Technical Bulletin

Description :
ORG 10 is a high pH formultion that has been designed specifically to remove organics, silt and other particulate deposits from polyamide, polysulfone and thin film composite membrane surfaces. This advanced, high s trength powder has the following features:

• pH adjusted to 10+ 0.5
   
• Highly effective at ambient temperatures
   
• Contains no surfactants and is quickly rinsed away
   
• Contains detergent builders, chelating agents and pH buffer

ORG 10  is suitable for use with all polyamide, polysulfone and thin film, composite membranes. It can be used at temperatures from 15°C (60°F) up to the maximum recommended by the membrane manufacturer.

The standard dilution ratio is 25 grammes of ORG 10 per litre of water

Cleaning Instructions

Inspect cleaning tank, hoses and cartridge filter. Install new filter elements.
Fill cleaning tank with RO permeate.
Slowly add 25 grammes of ORG 10  for each litre of cleaning tank capacity.
Thoroughly mix cleaning solution by using a mixer or by circulating it through the cleaning pump.
The solution may be heated to improve cleaning effectiveness.
Do not exceed the membrane manufacturer’s temperature limits.
Circulate the solution through the membrane bank in the feed direction for one hour at the flow rate recommended by the membrane or system manufacturer. If the manufacturer’s recommendations are not available, the following guidelines may be used.

Spiral wound membrane

 Hollow fibre membrane

In cases of heavy fouling, the first return flow (up to 15% of the cleaning tank volume) should be diverted to drain to prevent redeposition of removed solids.
In multi-pass systems, best results will be achieved if each pass is cleaned separately.
The solution should be discarded if it becomes turbid or discoloured by removed material.
A fresh solution should then be prepared before cleaning additional passes.

Rinse with permeate before returning the system to service.
