The present disclosure relates, in general, to water recycling systems,
and more specifically, relates to greywater treatment systems.
BACKGROUND
[0002] As the population increases, ever greater demands are being put on
natural resources. The natural resource that is becoming scarce is freshwater. Water
shortages have been experienced worldwide in recent years as population centers
exhaust their supplies of freshwater. Water shortages have a destabilizing effect on
local economies and may even lead to international conflicts. More than half of the
Indian population does not have access to clean water and generally relies upon the
groundwater which is highly contaminated with industrial waste and fertilizers.
[0003] As demands for potable water increase, communities will rely more
heavily on water conservation efforts that include water reclamation and water recycling. Generally, daily human water use produces two categories of wastewater, which are known as greywater and blackwater. Blackwater is wastewater that includes biological human waste and greywater is generated from domestic activities such as washing machines, lavatory use, and bathing and the likes. The greywater requires less treatment as greywater generally contains fewer organic compounds than blackwater and generally includes less pathogen contamination. By using treated greywater to flush toilets, for example, instead of using fresh, potable water, it can reduce the daily use of fresh, potable water by a certain percent in a typical family home.
[0004] Few existing systems include membrane bioreactors (MBR) that is
one of the significant method available in the market for the purification of greywater. It replaces clarifiers, media filters and reduces reactor size by combining physical membrane barriers with biological treatment. These characteristics make MBR a good solution for a greywater treatment system and greywater recycling. Greywater systems usually comprise plumbing, pumps and a bioreactor storage unit where the biological treatment occurs and the water passes through a membrane filter. However, the existing systems are complicated and expensive.

[0005] Therefore, there is a need in the art to provide a means that can treat
and reuse the greywater effectively.

This approach can use a phytoremediation process followed by exposure to sun-light under the influence of metal nanoparticles. The present disclosure can be described in enabling detail in the following examples, which may represent more than one embodiment of the present disclosure.
[0032] FIG. 1 illustrate an exemplary representation of a system for treating
greywater, in accordance with an embodiment of the present disclosure.
[0033] Referring to FIG. 1, system 100 configured to treat greywater that is
produced by human domestic operations that does not include significant
concentrations of human biological waste and can be used to water plants, irrigate
landscaping, and support other water-intensive operations. System 100 can include
a first set of pipelines 102 (also referred to as a three-way valve), a reservoir 104, a
first filter 106, a second filter 110, a second set of pipelines 108 and a storage unit
114, where the second filter 110 can include a hydroponic system with
nanoparticles that is configured to treat the water i.e., greywater.
[0034] Greywater is generally produced by domestic operations like sinks,
showers, baths and light industrial applications, such as washing machines, kitchen and, and has not yet been treated for pathogens. The system 100 described herein may be useful in high-density buildings, such as in apartments, dormitories, hotels, office buildings, other commercial buildings, schools and the likes. Some manufacturing facilities may benefit from the disclosed systems if the greywater produced by the manufacturing operation is not heavily loaded with chemical contaminants.

[0035] In an embodiment, reservoir 104 also interchangeably referred to as a
surge tank 104 configured to collect greywater from sources through the first set of pipelines 102, where the sources can include sinks, showers, washing machines, dishwashing machines and the likes. The first set of pipelines 102 can be configured in the building to receive used water from bathroom, kitchen, laundry, and the likes, which is collected in the reservoir 104. The first set of pipelines 102 coupled to reservoir 104 and allow the passage of water from the sources to reservoir 104. The reservoir 104 can include collection lines that are fluidically coupled to various sources of greywater, such as showers, sinks, and the likes that direct collected greywater into reservoir 104.
[0036] The greywater collected from the sources can be stored in the reservoir
104. The reservoir, upon operation of a pump 112, configured to allow the passage of water to the first filter 106. The first filter 106 can filter a first set of contaminates from the greywater, the first set of contaminates can include dirt, organic waste matters, paper, hair and any combination thereof.
[0037] The filtered water from the first filter 106 is passed to the second filter
110 through the second set of pipelines 108, where the second filter 110 also interchangeably referred to as hydroponic filter 110 that can include any combination of nanoparticles, dissolve oxygen (DO) and pH indicators for incorporation into plant structures, where the DO and pH indicator is a smart/internet of everything (IOT) based sensor 118. The hydroponic filter 110 with nanoparticles is configured to treat the greywater to filter a second set of contaminates from the greywater. The second set of contaminants can include minute impurities, additional particulate, pathogens in the collected greywater, where the particles greater or lesser than about 5 microns in size can be treated by the second filter 110.
[0038] The hydroponic filter 110 can include a rigid rack set at the water
surface to support plants that send down roots into the wastewater column. The rigid rack set at the water surface supports aquatic and terrestrial plants, where the nanoparticle diffuses into the plants via roots that absorbs impurities and degrade the impurities from greywater. Many aquatic and terrestrial plants have a good

capacity to absorb impurities and degrade them. The hydroponic filter 110 is designed in such a way that screened plants can be grown in hydroponic filter 110. The pH indicators can be added to the mixture for incorporation into the plant structure for monitoring pH.
[0039] In another embodiment, smart/ IOT based sensors 118 configured to
monitor and analyze the quality of the filtered water/grey water at different intervals, which helps to make valuable decisions in real-time. The screening of plants can be done at the first step to getting the best plant, which optimises the sustainabihty of plants for more than two cycles. Then the green synthesised nanoparticles can be added, which can synergise with plant roots and fasten the process of degradation of contaminants present in the greywater. The IOT based sensors 118 can monitor the whole system to observe at the interval of 4-6 hours, the required DO of treated water for recycling in the mainstream.
[0040] The hydroponic filter 110 can be integrated with specific
nanoparticles. Using this approach, there can be synergy among the nanoparticles, plant root system which can easily degrade the second set of contaminants from the greywater. The synergetic effect of plants and nanoparticles effectively and efficiently treat the greywater. In an exemplary embodiment, the nanoparticles can be made of metals selected from a group comprising iron (Fe), copper (Cu) and any combination thereof.
[0041] The hydroponic filter 110 with solar dish and nanotechnology is a
green approach to purify the greywater using sustainable energy resources. This approach can use the phytoremediation process followed by exposure to sunlight under the influence of metal nanoparticles. The phytoremediation is a bioremediation process that uses various types of plants to remove, transfer, stabilize, and/or destroy contaminants in the greywater. In this process, the plant releases natural substances through its roots.
[0042] The treated greywater from the hydroponic filter 110 can be stored in
a storage unit 114 that can be fluidically coupled to a pipeline 116 to distribute the treated greywater for reuse. The treated greywater can be used for domestic purposes like laundry, washing vehicles, toilets, irrigation purposes, and the likes.

For example, the water used from domestic operations like sinks, showers, baths can be collected in the reservoir and treated by the filters that can include hydroponic filter, where the treated greywater may be used again to flush toilets, washing clothes and irrigation purposes thereby reducing consumption of potable fresh water.
[0043] The embodiments of the present disclosure described above provide
several advantages. The one or more of the embodiments provides system 100 that performs solar-driven phytoremediation technique in which the rate of reaction depends upon the capability of nanoparticle to get diffuse into the plants via roots and increase the absorption of impurities.
