Disinfectant of R.O Membranes
OSMO DISINFECTANT is a liquid formulation based on sodium bisulfate used in different water treatment processes, and particularly in REVERSE OSMOSIS plants. Continuous dosing of OSMO DISINFECTANT ahead of the high-pressure pump provides a reducing action of chlorine and disinfecting of the membranes. The use of OSMO DISINFECTANT is also extended to the flushing of the membranes when the system is in idle condition thus blocking bacteria growth.
RO Bisulphite is a solution of sodium hydrogen sulphite (sodium bisulphite) used in the
preservation of RO membranes and as a de-chlorinating agent.
If the feed water to the RO system contains free chlorine it must be removed otherwise it can breakdown the RO membrane. RO Bisulphite is a 40% solution of Sodium Bisulphite (NaHSO3) It undergoes the reaction below with free chlorine:
2NaHSO3 + 2HOCl → H2SO4 + 2HCl + Na2SO4
RO-OSMO CLEAN-2 is a membrane cleaner specifically designed to remove rust accumulations, iron & other minerals fouling. It is also effective against light calcium carbonate scaling. RO-OSMO CLEAN-2 should be used in accordance to membrane manufacturers recommendations & OEMS. The cleaning solution temperature & pH value also to be adjusted to suit the system procedures to get the best performance. Fouled or scaled RO membranes reduce the system performance. In such case, product flow & quantity get affected. Therefore, preventive maintenance steps maintains the membrane performance & minimize losses. As a part of such steps, periodic cleanups of the membranes is suggested in line of membrane manufacturers & OEM Suppliers. This applies particularly for systems being fed with high metal ion foulants. However, it is suggested to conduct chemical cleanups either when the normalized product flow is reduced by >10% or salt rejection decreases by >10%, or the differential pressure increases by >10%.
RO-Osmo Clean-3 is a blend of alkaline organic components designed for effective RO membranes cleaning. RO-Osmo Clean-3 is effective in removing iron oxides & hydroxides as well as Calcium Carbonate & Calcium Sulfate. It is highly effective when used in combination with high pH detergents cleaners to help remove organic substances & microbial slimes. Moreover, it is a good general-purpose membrane cleaner designed to support the cleaning of acid insoluble’s sulphates of calcium, barium & strontium, as well as traces of calcium fluoride. During normal operation, reverse osmosis & other membranes can become fouled, which greatly reduces the efficiency of the system and proper functioning causing reduction in normalized permeate flow. The effects of fouling can lead to poor water quality, loss in production, unscheduled downtime & premature membrane replacement. A regular maintenance & cleaning program can provide a significant return on investment by extending system run time, prevents membrane degradation, maintaining lower feed pressures & extending the membrane’s life.
RO-Osmo Clean-10 is a broad spectrum scale inhibitor for Reverse Osmosis systems.
RO-OSMO CLEAN-10 is multipurpose antiscalant/antifoulant for handle and all membrane systems using a wide range of brackish, high salinity, process and effluent feed-waters. It is a highly effective scale inhibitor designed for reverse osmosis, nano-filtration & UF systems. RO-OSMO CLEAN-10 is a general antiscalant that inhibits inorganic scale formation on RO membrane surfaces. It functions by chemically interfering with crystal formation in the feed water and reduces the potential for adhesion between scale particles and the membrane surface. Typical mineral constituents such as Calcium & Magnesium carbonates, Sulfates and colloidal clay particles are maintained in a soluble state and dispersed to minimize or eliminate scale potential. It aids in prolonging membrane life and increases operational efficiency.
