Surface Water Treatment
The standard type water treatment plant is based on tradition and history. Experience demonstrates its ability to effectively treat most water, generally from surface sources. This surface water treatment plant style has proven to meet many challenging situations of extremes such as high turbidity, iron and manganese, cold waters and seasonal quality variations. The treated product is always safe and clear = quality water for your community.

The Process
Coagulant chemicals are injected in the feed stream to promote formation of flocculent particles, a grouping of dissolved and suspended contaminants. In the flocullation step, these particles form a bond within a delicately balanced turbulent flow. In the clarification step the particles separate to the bottom for regular de-sludge removal, whereas the clear water migrate to the top collector for filtration. In the final filter step, the clarified water is refined through the engineered layers of graduated filter sand selection, and the filter is maintained by a periodic air scour / backwash process.

Two-bed water de-ioniser consists of two FRP/MS rubber lined pressure vessels that are connected in series along with its internal fittings. The 1st vessel consists of strongly acidic cation exchange resin that converts the positive ions of salt and replaces them with hydrogen the ions to form respective acids. The acids hence formed are absorbed in the next vessel by strongly basic anion exchanges resin.

The water being obtained by such process shows conductivity less than 10 u S/ cm at 25 o C and total dissolved solids less than 10 ppm. This can also be further reduced to less than 1u S / cm using MIX BED DEIONISERS
