Envirotech Engineering Systems has taken step for processing the hard water and makes it usable. Hard water consists of excess quantity of calcium and magnesium which is highly dissolved in water but not suitable for drinking purpose. In fact, hard water may create many problems:-
* Decrease the water flow rate
* Increased electricity cost while heating or boiling
* Washing is not performed in better way
* Leave white stain on the glass surface
* Highly indigestive
* Not suitable for skin
Due to the above problems, it is required to soften the water and so the softening water plants are established which plays big role in cleaning this.
Softening of water is processed through the ion exchange and precipitation methods. This process rely on removing mainly two minerals i.e., calcium and magnesium with the flow of sodium. In this process, two separate tanks are associated with a pipe. These two separate tanks denote the brine tank and mineral tank. Mineral tanks consist of raw water containing minerals where as brine consists of the sodium chloride and both tanks are connected with a tube or pipe. As the process started, surface of vessels contains the calcium and magnesium which is flushed through the flow of sodium (salt) which is perfect and powerful solution for the minerals.
* Chemicals based softeners which is usually used in laundries to wash clothes by removing the magnesium and calcium but this water is not fit for drinking.
* Packaged water softeners are of two types – precipitating softeners such as washing soda and borax which react upon the calcium and magnesium and improves the cleaning efficiency, whereas in non-precipitating softeners, phosphates are used for removing the minerals to great extent.
Knowledge of law of the land (national and international rules and regulations) in regards to water and wastewater treatment that you have to comply with.
* What quantity of effluent is produced in your entity on daily basis?
* The chemical contents and their concentration in the effluent. For instance, 30m3/hour with COD of 500ppm, and pH of 11.5.
* What is your budget for installing and running the ETP?
* Can you spend on its maintenance once it is installed?
* Do you have enough and suitable land area for the desired construction and installation?
* Choosing the right vendor is one of the critical factors to consider. An expert in the filed who provides excellent aftersales service should be considered.
* As there are many types to consider, choose the ETP that best suits your company requirements.
* Better recruitment and training to the personnel responsible for operation and maintenance of the plant.
