The main goal of pretreatment is making feed water for the Commercial RO Plant compatible with the membrane. Pretreatment is necessary to reduce membrane fouling, scaling, and degradation, and extend the effectiveness and lifespan of the membrane elements.
As we all know, Reverse osmosis (RO) is currently one of the most frequently employed water purification techniques, in both the public and private sectors. Large and small communities can purchase Commercial RO plants from Netsol Water, a well-known manufacturer of water treatment plants.
For the proper functioning of the Commercial RO Membrane, every RO Plant needs pretreatment, which includes the best methods so that the lifespan of the membrane will be increased.
Which pretreatment methods are used in commercial RO Plants?
A few pre-treatment techniques for reverse osmosis plants include softening, dechlorination, and antiscalant treatment. After pre-treatment, high pressure is applied to force water through a semipermeable membrane, which retains contaminants and lets pure water through.
1: Water Softening Method
The ion exchange principle is used by ion exchangers to remove dangerous minerals from water. Water softeners change scale-forming salts like calcium sulfate and magnesium bicarbonate into soluble, non-scale-forming sodium salts.
They are non-scale-forming because sodium compounds are highly soluble, and do not precipitate out of solution to create scale. Deionizers and demineralizers remove even more minerals from water.
Ion-exchange offers several advantages
The method is more easier and the chemicals used are much safer for the operator to handle. You could automate everything totally. Moreover, automatic duplex softeners are an option, guaranteeing a steady supply of soft water for crucial uses, like boiler feed.
2: Dechlorination Method
Prior to water being distributed into the receiving environment, leftover wastewater is removed via de-chlorination. The currently available dechlorination method makes use of tablets.
When the residual chlorine content is too high for the RO membranes to handle, dechlorination is performed. This is typically kept constant during the pretreatment at 0.5 to 1.0 ppm. Before transferring the water to the RO unit, dechlorination is required because the majority of membranes can only handle 0.1 ppm of chlorine.
3: Antiscalant Treatment
For reverse osmosis systems, antiscalant is a water pretreatment additive that is very successful, at preventing the membranes from scaling. An antiscalant is added to the feed water and circulated through the system, before the water reaches the reverse osmosis membrane.
The reaction causes a lag between the calcium magnesium and bicarbonate. The delay gives the water enough time to cross the membrane, before any chemical reactions that could lead to the formation of scale. This prevents scale from accumulating while the RO is purifying the water.
