Chlorine Scavenger Removal of residual chlorine from feed water
Corrosion Protector Corrosion inhibitor for permeate distribution systems
Cleaners Successful membrane clean depends primarily on the nature of the foulant. Before electing cleaning chemicals and designing a cleaning protocol it is vitally important to correctly identify the deposit or foulant trough a RO feedwater proper lab analysis and Membrane Autopsy Service. For the most effective cleaning, and therefore reduced cleaning frequency, conditions of pH, temperature and contact time are important.

Due to a different RO feed water ionic composition, it is necessary to have a proper lab analysis. As a result, different types of scale may deposit on the membranes if the correct antiscalant and/or dosage is not used. To provide optimum operating conditions for both Sea and Brackish Water RO plants, it is imperative to select the correct antiscalant. Correct product application in the RO feed water is critical to ensure the optimum plant operational performance is possible, reduce the overall costs through energy savings, reduced cleaning frequency and extend the life of the membranes.
