Document Type and Number:
WIPO Patent Application WO/2012/165748
Kind Code:
A1
Abstract:
Provided is a method for washing a filtration membrane using novel disinfectant applied to water treatment, and a method for controlling biofouling. The method for washing the filtration membrane includes a step of disinfecting raw water, inflow water, and a filtration membrane using a solution including isocyanurate to minimize damage of the membrane and maintain superior performance. Microorganisms which form a biofilm and cause biofouling may be inactivated to maintain a high salt removal rate and a stable amount of water penetration.
