Raw Water Treatment (Potable Water)
Raw water like Industrial Development Corporation piped water supply, direct surface water, ground water is requiring pre- treatment and post treatment before sued for different industry processes and applications. Disinfection is required to remove microbiological contamination from water.
Purita offers following products in the area of disinfection of raw water;
- TERSUS® Chlorine Dioxide [CLO2] System
- TERSUS® Electro-chlorination [ECP] System
- TERSUS® UV System
- TERSUS® Ozone System
- TERSUS® Advance Oxidation Processes [AOPs]
The preferred technologies applied are Chlorine Dioxide / Electro-chlorination in Pre-treatment. In the pre- treatment step, they are usually added into the Raw water collection tank as per site condition and requirement. The purpose of such treatment is to prevent bacterial growth in the collection tank.
For further treatment, it is suggested to use additionally UV Technology / Ozone Generator / AOPs as a full proof solution to prevent the any kinds of bacterial, virus, fungi, algae etc., being carried forward in the potable water. It is also advisable to implement such technologies for the purpose of specific bacterial prevention like Pseudomonas / Salmonella / TOC reduction.
Effective micro-organism control helps down-stream Purified Water System like RO-EDI. As a safe guard, it is suggested to use UV system for residual ClO2 / Ozone destruction before pre-disinfected water being fed to the RO-EDI plants.
