RO Membrane Cleaning

Before Cleaning

1. RO plant has been shutdown for 2 years. RO plant closed without preservation
2. On opening of RO membrane, it was found that high biological growth found inside the pressure vessels and membrane surface.
   
3. All Membranes had been stuck up because of organic and inorganic fouling.
   
4. Hard layer of sclae formed on the membrane surface

Cleaning Method:

1. Each membrane was taken out and CIP was done.
2. Alkaline Cleaning and Acidic Cleaning performed for each membrane
   
3. After cleaing flow improved 100%
4. Membrane TDS also reduced
