BACKGROUND ART
Chemical treatment of water is an important requirement of any recirculating water circuit in a number of industrial processes and applications. It is well known in the existing art that such treatment of contaminated used water for recycling as coolant or other application, conventionally involve dosing of various required chemicals for achieving end characteristics based on application and end use directed to reducing turbidity, scale formation, algae formation, corrosion reduction or oxygen scavenging and the like. The nature and time duration for the chemical treatment program varies substantially depending on input as well as output water quality and characteristics. Often, there are competing needs and conflicting objectives of meeting the end results. As for example, mildly acidic water is good for reduction in scale formation but may lead to corrode pipelines on longer use; On the other hand the chemically treated water that is basic in nature, may be good in reducing corrosion but can lead to mild scale formation affecting adversely the cooling characteristic of water when recycled as coolant. Moreover, various standard chemicals used for treatment purpose are patented and having chemical properties often unknown. It is thus not possible to compare effectiveness of these chemicals on-line in relation to meeting the end objective of the recycled treated water and no available technology/system provides supports to meeting such requirements. It is hardly possible to check effectiveness of these commercially available patented chemicals in determining major end effects like avoiding scaling, corrosion etc that are gradual and time taking processes, making the treatment process and the end parameters targeted to achieve to be a matter of subjective decision with trial and error approach.
There has therefore been a continuing need in the existing art for monitoring and management of water treatment process parameters for recycling for cooling or other purposes in various industrial processes to specifically optimize multiple parameters for effectiveness of water treatment off-line and check effectiveness of this treatment through a controlled system adapted to dosing, stirring and tapping for treating water samples on a experimental scale to ensure supply treated water of desired chemical and physical characteristics favorable for intended recycling purpose avoiding the detrimental corrosion and scaling effects in a simple, safe, reliable and cost effective manner and also to enable a follow-up process to evaluate and control on a sustained manner. The system is further adapted to be scaled up to operate with equal efficiency and quality multiparametric optimization for water treatment in actual plant scale operation.

Three pairs (3x 2 jars of 1 litre capacity) of dosing containers(DC) are provided with Servo Solenoid switch(SW) having size of 1/4 inch BSP at both ends at the top most level. The six containers are connected through six keys to three numbers of solenoid valves (SV) for controlled dosing. Suitable electrical power supply is provided for operating these solenoid valves(SV) based on optimized parameter values/set points decided by the microprocessor and related command/signal generated. Such valves are normally closed when output is zero and are operated when controller allows to open the valve to pass the particular reagent to reach to set point, so long the waste water sample is maintained in the containers(SC) in the next lower level. Three of such sampling containers(SC) each having 5 litres capacity are arranged provided with stirrers and independent solenoid valves. A further Liquid locking valve mechanism is used by means of Teflon lock. Such an off-line experimental set-up is adapted for accommodating acidic solution with permissible limit upto N/50. Each of the sampling jar is provided with Stirrer/vibrator(ST/VB) for stirring /shaking of the solution during experimental run. The output from the sampling jars at the intermediate level is fed to the collecting container(CC) of 5 litre capacity at the bottom most level on stand wherein the treated water with optimized parameter values based on set points and operation of independent solenoid valves, are collected by batches of feed of sample.
It is further important to note in said accompanying Figure 2, that the dosing attachment containers(DC) are made of borosilicate glass, fitted with stopcock. TAP-with Vi inch BSP threading at end. Made of PP/PC/HDP material, fitted in all four containers. A sample lifting motor-pump having capacity of 10-11 LPM is provide in the system to lift treated water from respective jar to use/analysis points. The required pipeline uses 1/2 inches BSP connection or nozzle for pipe-fittings. The PVC motor(MT) made of PP/HDP material, having about 20 ft nylon pipe, motor and pump(MP) is completely sealed so that the same can be dipped into sample for lifting to container.

The central processor monitors the wastewater sample chemistry and decides on dosing of chemicals in isolation or combination. The display panel (DP) provides/indicates the instantaneous parameter values corresponding to each of the dosing/sampling jars/containers during wastewater treatment for recycling and the matching with respective set point values.
The system for management of water treatment through multi-parametric treatment optimization as of the present invention having said microprocessor based control unit thus enable all required chemicals being dosed automatically as per requirement to a pre-set desired value and therefore optimization of dosing can be carried out through a number of simple steps. The apparatus can handle all kinds of recyclable water. More advantageously, the apparatus facilitates easier comparison of various chemicals for their effectiveness in water and wastewater treatment and can also be used as a post-treatment monitoring apparatus.
The manner of implementation of the off-line water treatment through multi-parametric treatment optimization and its management is achieved through automatic dosing of treatment chemicals using the above described system and apparatus according to the invention wherein the following simple steps are sequentially followed to attain desired characteristics of the treated water for recycling,
a. Various chemicals such as the biocide, scale inhibitor, corrosion inhibitor or oxygen
scavenger etc. are kept in the top row containers at a particular selective dilution
level.
b. The water sample is to be taken in a plurality of container with stirrers, solenoid
valves, taping points etc. in the second row, comprising either 5 or six numbers of
such jars made of borosil glass.
c. The set points of various parameters like pH, ORP, Conductivity, TDS, Turbidity, DO
etc are to be set as per requirement of controlling parameters in a closed loop
system depending on end use of recycled water.
d. Dosing of liquids from top row containers are done through solenoid valves to sample
water container.
e. Solenoid valves works on on-off control mechanism and it stops dosing when set
points are reached for a particular parameter in water container and the signal is

sent to valve through container, operatively through the microprocessor based control unit of the system.
f. The first set of data points are generated for individual chemical dosing levels to
achieve respective independent parameters.
g. The second set of data points to be generated by two parameters taken in
combination.
h. When there is no interaction between parameters all the valves will be closed when
pre-determined set point is reached which will determine the optimum dosing level, i. When there is interaction between parameters valves will re-open, j. Data points are recorded with reference to time, k. When there is re-opening of valve the experiment is repeated at a different dilution
level with the chemical concerned. I. When rate of change of parameters becomes negligible or dosing rate reduces
significantly optimization of dosing is understood to be achieved, m. These Steps can be repeated for comparative assessment of various chemicals used
for water treatment.
According to one embodiment of the invention, the above steps implemented experimentally with sample water of unknown character and the corresponding validation of data using patented chemicals directed to optimize parameters in treated water as end product of desired characteristics, are as given in the following Table 1 :


The above results clearly indicate that recommended doses of chemicals are at a relatively higher level than actually required by experiment. However, this is done to protect the equipment from any sudden change in characteristics of sample water. The set points are deterministic of the desired optimized parameters in isolation or in combination as required in the treated water for its intended end use.
