Stronger decolorization (>95%) and removal of COD, BOD (40-70), Faster sedimentation, better floculation, Non-Pollution (no aluminium chlorine, heavy metal ions etc...)
The Raw water contains Hardness salt and silica which will concentrate on the reject side and precipitate on the membranes on reaching their saturation limits. Thus choking the membranes and affecting the operating performance.
In order to avoid scaling of the R.O. Membranes due to prcipitation of the hardness salts or silica on reaching their saturation level a Antiscalant are required to be dosed.
This is special polymer based Antiscalant used to control the precipitation of hardness salts & silica.
(i) RO plant
Puretreat RO30(Silica and Non-Silica). (ii)Evaporator Puretreat E30.
Polyelectrolyte helps in better Flocution due to its special characteristics of absorbing micron size particle and to form a heavy floc. This is a latest innovation in the of Filtration.Purpose of providing polyelectrolyte dosing after coagulant dosing better Filtration to make effluent as clear as possible.
Free chlorine if present in the water may prove to be injurious to the RO membrane. Hence it is very essential to Dechlorinate the water in the pretreatment of RO System.
