FIELD OF INVENTION
The present invention relates to a device for Scale Prevention in water and process of manufacturing the same. More particularity, present invention provides a device made up of plastic having intrinsic property of buoyancy on water surface to treat water with poly phosphate to inhibit scale in water and collectively provides benefit of price benefit, durable, safety, light weight, compliant with standards and environment friendly compared to state of the art technologies.
BACKGROUND OF INVENTION
A Scale Prevention System is typically an antiscalant polyphosphate dosing system or device designed to eliminate or prevents hard water scaling from magnesium and calcium from the water. What many people may not realize is that not all water is identical, especially when it comes to its chemical composition. Some water contains high concentrations of magnesium and calcium minerals that have been absorbed from the earth, resulting in hard water. Conversely, water that lacks these minerals or has them in minimal quantities is considered soft. Natural sources like streams and lakes typically yield soft water.
However, underground water in regions abundant in chalk, gypsum, and limestone tends to be hard. Consequently, to convert hard water into soft water, a water softener is employed to remove the mineral components responsible for its hardness. This process, known as water softening, involves the removal of calcium, magnesium, and other metal cations from the water.
With the rapid economic development in India, there is an increasing demand for water. Tap water in many areas is characterized by high hardness, primarily due to elevated concentrations of calcium and magnesium ions. This hardness gives rise to issues such as scaling, poor results in facial cleansing and bathing experiences, among others. Household water softeners come to the rescue by treating tap water, eliminatingcalcium and magnesium ions, and producing soft water. This, in turn, reduces scaling and enhances the user's experience when washing their face or bathing.

The household water softener incorporates a cation exchange resin, which, during its operation, adsorbs calcium, magnesium ions, and similar impurities found in tap water. This process effectively reduces the water's hardness. However, when the ion exchange resin reaches its maximum capacity, it can no longer effectively soften the water and requires a regeneration treatment. This regeneration process entails the preparation of saturated brine by adding sodium chloride to a salt tank. The ion exchange resin is then washed with this brine to restore its capacity.
In the state of the art, water softening system is disclosed that rely on predetermined schedules for salt replenishment, occasionally causing inconvenience due to untimely salt addition.It is to be noted that the current water softener posses some limitation like they are not easy to maintain, it’s frequently required to add salt, regeneration of salty water, wastage of large quantity of water as effluent, operation through electricity, difficult installation in existing plumbing of house, tedious maintenance of salt and overall dimension occupies large space.
Polyphosphate is a condensation polymer of orthophosphate commonly used in water quality stabilisation treatments. Mostly available in market with different variants i.e. sodium tripolyphosphate (Na5P3O10) and sodium hexametaphosphate (Na6P6O18). The recommended dosage for the former is typically 2 to 5 mg/L, while the dosage for the latter is generally 1 to 5 mg/L. It is observed that the Increase in the dosage beyond these levels will not yield better results and may even lead to the formation of a white precipitate due to exceeding the solubility of polyphosphate in water. The solubility of commercially available polyphosphates typically hovers around 4 ppm. Additionally, under certain conditions, polyphosphate can create a protective film on metal surfaces, inhibiting corrosion.
In the current state of the art, polyphosphates have found extensive use in a wide range of anti-scale products. Specifically, in this application, polyphosphate filter material primarily refers to polyphosphate glass balls, although other forms of polyphosphate particles can also be employed. These polyphosphate filter media are readily available on the market.
However, a significant challenge associated with polyphosphate filter material is its high autolysis rate. When placed in a container, it tends to dissolve upon contact with water or even water vapour. Consequently, it depletes itself regardless of whether it is effectively used, leading to a relatively short lifespan. This limited service life is determined by the dissolution rate of individual polyphosphate filter material units. Regardless of the quantity added, each polyphosphate filter material unit dissolves at the same rate, and this does not extend the overall lifespan.
Another issue arises under specific water quality conditions, where polyphosphate may not function as intended. In these scenarios, with rising temperatures, polyphosphate rapidly decomposes into ortho-phosphorus, resulting in the formation of a white precipitate. In such cases, the polyphosphate filter material loses its polyphosphate properties and its ability to complex and mask calcium and magnesium ions. Instead, it contributes to phosphate scale formation, exacerbating scaling problems.
A more significant drawback is that in stagnant water, the polyphosphate filter material has a high self-dissolution rate, and its solubility in water is notably low. When self-dissolution reaches a certain concentration, it can lead to substantial precipitation within the container containing it, potentially clouding the water.
As is widely recognised, preventing the buildup of scale inside cooling and heating equipment, such as geysers, washing machines, water purifiers, and similar devices, is essential. To address this, systems that remove the hardness components present in the supplied water are connected to the water supply lines of these cooling and heating devices. Among these, automatic regenerating water softeners, utilising an ion exchange resin system, have gained significant popularity. This type of water softener employs a Na+ type of ion exchange resin, which displaces metal cations like Ca2+ or Mg2+ with Na+ ions to eliminate the hardness components. When the resin becomes saturated and loses its ability to remove hardness components through ion exchange, it is regenerated by flushing it with a saline solution. During the regeneration process, soft water cannot be supplied, which is why two water softeners are often used. Water flows alternately through these softeners, ensuring a continuous supply of soft water.
It's worth noting that metal cations like Ca2+ or Mg2+ can convert into CaCO3 and MgCO3, forming thick scale deposits inside pipes and other water-operated equipment. Polyphosphate (PO3) offers an ideal and simple solution to remove scale as it gradually dissolves scale from deposited surfaces.
Hard water is responsible for problems such as stiff laundry and dry hair because it reduces the ability of water to interact effectively with soap. This makes it challenging to wash hair properly and also hinders the effectiveness of laundry detergents. A water softener effectively eliminates these issues.
As previously mentioned, water softening employs a filtration device, system, or appliance to eliminate calcium and magnesium ions from hard water, thus making it soft. There are three general types of water softeners:
Reverse Osmosis: This device allows water to pass through a semipermeable membrane, removing approximately 98% of impurities. It does consume a significant amount of water and is relatively expensive but excels at removing chemical impurities like magnesium and calcium.
Ion Exchange: The most common type of water softener, known for domestic use, works by replacing calcium and magnesium metal ions with sodium ions. A large tank is filled with salt pellets, and hard water is passed through it. The sodium ions in the salt react with and replace the calcium or magnesium ions in the water, resulting in soft water.
Salt-Free: This device uses a mechanical filter to remove calcium and is less effective with water containing magnesium. It is primarily designed for removing calcium from hard water and may not work as well with water that has high magnesium content.
None of the state of the art provides optimised yet economical solution for the hard water Scale Prevention System.
OBJECT OF THE INVENTION
The main object of the present invention is to provide a device for Scale Prevention with buoyant features in water tank by inhibit scale and process of manufacturing the same.
Another object of the present invention provides is to provide a device for water scale free that gets rid of calcium, magnesium, and certain other metal Cation in hard water.
A further object of the invention is to provide a device that renders scale free water which requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions.
Another object of the present invention provides is to provide device that lead to Scale free water which indirectly extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes and fittings.
Still another object of the invention is to provide a device that inhibit the scale by forming smooth layer on cations like calcium and magnesium ions which are responsible for water hard, and relatively safe for use and consumption and also overcome loading of Na+ ions of earlier state of the art i.e. Ion Exchange mechanism.
Another object of the present invention provides is to provide water scale free device that is made up of plastic, easy to manufacture, easy to adapt with economical significance.
A further object of the invention is to provide a device for water de-scaling the ground hard water which is generally responsible for endless appliance repair bills and scale-ridden pipes and also saves sinks, bathtubs, and toilets from the annoying stains.
A still further object of the invention is to provide, in a device of the character set forth, novel means for strengthening the legs of the same.

DETAIL DESCRIPTION OF INVENTION
Prior to delving into a detailed explanation of the present invention, it is important to establish that the invention's application is not restricted solely to the specific arrangement of components depicted in the accompanying drawings. The invention has the potential to manifest in various embodiments, as illustrated in different figures, and can be implemented or executed through a range of methods. It should be emphasised that the language and terminology used here are employed for descriptive purposes and should not be regarded as limiting factors.
Fig, 1 describes perspective side view of the device of the present invention. The device depicts two compartment i.e. Upper compartment (2) and Lower compartment (3). The upper compartment (2) is air tight plastic container having preferably funnel type cone shape device that has glossy surface on the top circular part (4) and gradually inclined to the bottom that provide rotational inertia advantage to the device. The top surface of upper compartment is relatively flat and glossy that minimises the chances of water retention on the top of the device. The shape of upper compartment (2) is optimised with a view to keep the assembly floating over the water surface. The inclined lateral side (6) of the upper compartment (2) provides constructional advantage of floating in water tank during water inflow or water discharge time. The shape also provides easy rotational movement to the assembly in the case of waves or turbulence generated in the water tank (9). The lateral surface (6) plays vital role to satisfy the core object of the present invention i.e. the maximum momentum of the assembly into the water tank. The prior art provides static anti scaling device that is positioned at bottom of the tank with the rope of cable at the opening hole of the water tank.
Fig. 1 depicts second compartment (2) in lower portion of the assembly (1), where tubular structure with lateral slit (7) provided with threading on top of the compartment to connect with the upper part of the assembly [As depicted in Fig. 5]. The tubular structure of lower compartment (3) is generally with reducing surface area from top to bottom that also provides effective floating inside the water tank (9). The lower compartment (3) contains lateral slits (7) throughout the periphery of the compartment which facilitates water inward from water tank (9) and outward from the compartment (3) towards the water tank (9) during operation. The said arrangement provides pendulum type floating to the assembly (1) when submerged into the water tank (7).
Fig. 2 illustrates a sectional side view of present invention where in device is sum-merged in water tank (7). The assembly or device (1) submerged in water tank (7) wherein floating of top plate (4) over the water level as been observed due to buoyant property of the upper compartment due to intrinsic property of air to keep on higher position into the water tank (9). Generally, the device is expected to be submerged beyond juncture (6) of the present assembly (1). It is also submitted that once the anti-scaling material i.e. polyphosphate which is accommodated in lower compartment is reduced to substantial level i.e. upto 80-85% then the assembly will not dragged down due to no gravitation force and therefore the device is compromised its original upright vertical position and tend to float with relatively horizontal position. The said position is indicative for the user to refill the anti-scale material i.e. polyphosphate into the lower compartment (3).
Fig. 3 illustrates a cross sectional side view of present invention where in device is provided with loaded anti scaling material i.e. polyphosphate. Fig. 3 depicts cross sectional view that accommodates polyphosphate inside the lower compartment (2). The compartment (2) is easy to open and fill without any specialised skill or tool. The assembly is compatible to accommodate other type of anti-scale material in form of crystal or ball or pouched packed other anti scale composition. The assembly or device (1) provides maximum surface area to exchange ions into the water stored in the tank (9) due to turbulence at the time of water filling from upper side of the tank. The device contains constructional advantage feature that provides pendulum floating at the time of turbulence or waves to achieve equilibrium for ion exchange in the whole water tank (9).
Fig. 4 illustrates perspective side view of the compartments in de-coupled position. The upper and lower components (2, 3) are provided with plastic material that can withstand shocks of operation. The material is rigid enough to withstand movement of the water force or shocks or jerks received by striking with the walls of water tank and on the other end lights enough to serve the purpose of the invention buoyant effect. The de-coupled view of the upper assembly shows threading portion that lower end and vice versa the lower portion provide threading portion at top side of the component. The said fig depicts the easy to use or operate by the user using simple means without any skill or tool. The said arrangement is useful during maintenance i.e. cleaning of lower compartment if the slit are clogged by water impurities after extensive use. The upper compartment and lower compartment is manufactured with die cast or molding method that contains steps of manufacturing plastic parts from plastic beads through optimised parameters. The manufacturing process steps involve uniqueness pertaining to the process parameter to achieve fine finished product components with respect to assembly of the present invention. As disclosed in the Fig. 4 the upper compartment can be divided into the flat surface (4) and conical lateral surface (5) in order to achieve convenience of the production. The snap fit arrangement is provided to connect these parts (4, 5) for fast and convenient fitting of the parts.
The general grade of plastic used in the present device is pertaining to ABS, PC, PP, PET, PVC, CPVC or HDPE.
The present invention is disclosed herein as preferred embodiments and it is possible to modify the concept of upper and lower compartment by deviating size and shape of the component to get suitable to higher capacity water tank. In other embodiments, like underground water tank the assembly can be used with relatively large sizes of upper and lower compartments. In that case second compartment requires carrying adequate quantity of polyphosphate proportional to the water tank storage capacity. Further in order to have buoyant for the large capacity water tank, the shape of upper assembly can be rectangular or square with relative higher capacity to withstand more weight at the surface. Similarly, lower compartment can be modify to accommodate higher quantity of anti-scaling material and accordingly later slits will be position in the lower compartment. The guiding means (rope or cable) to retract the device will also be provided at suitable position to serve the device in underground water tanks. The user can install multiple devices in case of high TDS water or treatment required for large water tanks.
Following are the advantages of the device:
· Light weight
· Simple
· Device operating without electricity
· Low cost solution to hard water treatment
· No maintenance
· Efficient
· Easy to transport
The present invention provides process advantage in manufacturing of metal plate and plastic arm by considering the environmental impact and carbon foot print while developing each component.
While, the invention has been described with respect to the given embodiment, it will be appreciated that many variations, modifications and other applications of the invention may be made. However, it is to be expressly understood that such modifications and adaptations are within the scope of the present invention, as set forth in the above-mentioned provisional patent application.
