An in depth study of the incoming water prompts Sparkle to suggest a membrane based clarification system, which not only brings down the water to safe disposal limits but also makes it good enough to be used in the boilers. Modification in the operating parameters suggested for achieving better quality at the outlet. This ETP outlet water is further sent for post treatment as given below.
An extensive system for water treatment is suggested with the following flow scheme, Bag Filter – Activated Carbon Filter – Pressure Sand Filter – Ultra Filtration – Reverse Osmosis. A gradual reduction in the suspended impurity load is effected in each successive stage. The Ultra Filtration system brings down the turbidity and fine suspension levels drastically so as to make the water quality appropriate for feeding to Reverse Osmosis. The Reverse Osmosis system effectively brings down the Total Dissolved Solid levels in the final permeate less than 80 parts per million which is good enough for boiler water intake.
The treated water is
