Dechlorination For RO

  Most U.S. public water supplies today are disinfected with either chlorine or   chloramines   (chlorine mixed with ammonia). For disinfection,   chlorine   is generally added as a gas or liquid (typically as sodium hypochlorite) to produce free chlorine residual of 0.5 parts per million (ppm) to 2.0 ppm. Unfortunately, chlorine and its related compounds are oxidizing agents and can have harmful effects on medical and industrial procedures or processes. Even low concentrations of chlorine can rupture a patient’s red blood cells when going through hemodialysis. These compounds can also cause stress cracks in stainless steel, alter and damage active pharmaceutical agents, or lead to undesirable by-products. Water treatment systems are no exception;  reverse osmosis membranes  and  ion exchange resins  will deteriorate and degrade when chlorine is present. Removal of Chlorine Free chlorine and chloramines can be removed in several ways which are described below: Adsorption Dechlorination

  Chlorine (Cl2) has long been an essential component in municipal, industrial and wastewater treatment due to its ability to eliminate most pathogenic microorganisms. Chlorine (Cl2) has long been an essential component in municipal, industrial and wastewater treatment due to its ability to eliminate most pathogenic microorganisms. However in reverse osmosis (RO) systems, membranes are easily damaged by chlorine in the feed water. Chlorine damage to the membrane can lead to lower salt rejection and poor-quality permeate, which in turn could result in costly membrane replacement and down-time. If chlorine is present in the feed water, it is common practice to neutralize it with a sodium sulfite solution, a carbon bed, or combination of the two. Either technique works well, but sometimes operators who use these technologies and monitor their chlorine levels are surprised when they discover that their RO membranes are still damaged by chlorine. Some of the reasons chlorine slips past the

Acuro Organics Limited - dechlorination chemicals have been specially formulated for long term shelf-life and are odor-free.  In addition to neutralizing free and combined chlorine to protect RO/NF membranes , they also deactivate all other oxidizing and non-oxidizing biocides; this makes them essential tools for environmental discharge.

  Concentration of residual Chlorine after disinfection or oxidation is often too high for distribution, discharge to the environment or for other downstream processes such as reverse osmosis desalination. Amongst other methods, chemical dechlorination by means of Sodium Bisulphite (NaHSO3) is very common for various reasons: The reaction between Chlorine and Sodium Bisulfite is practically immediate, comes at a lower costs than other chemicals and is widely available 1.   INTRODUCTION When RO membranes are in use, the feed water must be dechlorinated to prevent oxidation of the membranes. The main role of dechlorination of water is the removal of high chlorine concentration levels. Chlorine is often used in water disinfection and other oxidation processes such as iron and manganese removal. Concentration of residual Chlorine after disinfection or oxidation is often too high for distribution, discharge to the environment or for other downstream water treatment processes such as revers
