RO Membrane Biocide
RO membrane biocides are chemical compounds that are designed to prevent biological fouling or to remove bio-foulants from RO membrane. It has two variations viz. oxidizing and non-oxidizing micro biocide which helps in disinfection of Reverse Osmosis/Nano Filtration/Ultra Filtration membrane. Oxidizing type biocide is safe for potable Reverse Osmosis system and is highly efficient against broad spectrum micro-organisms. RO Membrane Biocide is completely biodegradable and is totally chlorine free and eco-friendly. The main reason of using an effective biocide program is to control bio-fouling in the membranes so that it can be relatively cost effective compared to cleaning programs.
Functions of Silver in ALSTASAN SILVOX
Silver shows oligo-dynamic effect or toxicity on bacterial cells even in relatively low concentrations. Silver ions denature enzymes of the target cell or organism by binding to reactive groups, resulting in their precipitation and inactivation. Silver inactivates enzymes by reacting with the thiol groups to form silver sulphides.
Hydrogen Peroxide is not stable which means that it decomposes to oxygen and water. To solve this problem silver is added to hydrogen peroxide as stabilizer. This stabilizer prevents the slow decomposition of the hydrogen peroxide. The Ag2+ ions keep O2- ions.
The silver performs as an activator. The singularity of this silver activator is that it only activates the peroxide when it is exposed to biofoulants. In contact with microbes the silver loses its stabilizing function and activates to release nascent oxygen to oxidize the exposed microbes. When all bacteria have been oxidized by the generated active oxygen compounds, the silver acts as stabilizer for the remaining and non-reacted oxygen.
