MembraneGuard MG 11 Silt Remover
Remove organics, silt and other particulate deposits from polyamide, polysulfone and thin film composite membrane surfaces
The high pH formulation MembraneGuard MG 11 Silt Remover was created especially to remove silt, organics, and other particle deposits from polyamide. Thin film composite membrane with polysulfone surfaces. This cutting-edge, extremely potent powder has the subsequent characteristics:
- pH was set at 10.0 + 0.5.
- Extremely efficient at room temperature
- Is easily washed and has no surfactants
- Contains chelating agents and detergent builders or pH buffer
Dosage: 25 gm per ltr of water
How to use MembraneGuard MG 11 Silt Remover:
- Add RO permeate to the cleaning tank.
- Add 25 grams of Floclean MC11 gradually for every liter of available cleaning tank space.
- The cleaning solution can be heated to increase cleaning efficacy.
- Use a mixer to thoroughly mix the solution or run it through the cleaning pump.
- Adhere to the temperature restrictions set by the membrane manufacturer.
- For one hour, follow the flow rate suggested by the membrane or system manufacturer and circulate the solution through the membrane bank in the feed direction.

To avoid the removed solids from redepositing, the first return flow—up to 15% of the cleaning tank volume—should be routed to the drain in cases of severe fouling. For multi-pass systems, cleaning each pass independently will get the greatest results. If the removed material causes the solution to become turbid or discolored, it should be thrown out. Before cleaning more passes, a new solution needs to be made. Before putting the system back in service, rinse it with permeate.
