RO antiscant

Scaling is caused in membranes because the level of hardness salts in the water becomes highly concentrated as it passes through the RO unit. In smaller units scale formation can be prevented by base exchange softening the make-up water but for larger systems that is very expensive. We have developed a range of easy to handle, cost effective RO Antiscalant which increase the solubility of the hardness salts so they remain in solution rather than forming scale on the membrane. Our cost effective RO antiscalants will inhibit a wide range of foulants including: calcium carbonate, calcium sulphate, barium sulphate, strontium sulphate, calcium fluoride, silica and iron.

RO Antiscalants are dosed directly to the RO feed water tank or feed water line (after pretreatment) at the recommended dosage of 1-3 mg/L and maximum dosage at 8mg/L, subject to inlet water quality and parameters is respect of Calcium Hardness, Iron, TDS, Alkalinity, pH and silica content. Maximum dilution should be 10% with RO or DI water for temperature less than 30 deg C. For higher temperature the dilution ratio can increase. 

Key Features and Benefits

  • Inhibit scale formation and effectively controls corrosion
  • Protects the membrane efficiently
  • Enhance the plant operation and equipments life span
  • Economical
  • Easy in usage and handling

 

Our RO Antiscalant (HIGH PH) is a super-threshold RO membrane antiscalant and antifoulant which is able to stabilize a wide range of supersaturated salt solutions, thereby preventing the precipitation on the membrane surface. 

It reduces the risk of scaling and eliminates the use of hazardous acids,resulting in efficient plant operation with highest possible conversion rate. 

It is a very effective antiscalant . It is also compatible with RO CHEMICALS series of coagulant and flocculants (polyelectrolytes). Our RO Antiscalant (HIGH PH) is effective in minimizing scaling in presence of foulants like Calcium Carbonate, Sulfate salts of Calcium, Barium, Strontium and Magnesium, Calcium Fluoride, Iron and Silica.

Key Features and Benefits

  • Effective scale inhibition 
  • Alkalinity builder 
  • High recovery rate 
  • Low Chemical dosage 
  • Cost Effective 
  • Effective Iron fouling control by sequestration 
  • Reduced frequency of membrane cleaning 
  • Compatible with all types of membranes 
  • Completely organic and biodegradable 

Application and Dosage
Our RO Antiscalant (HIGH PH) is dosed directly to the RO feed water tank or feed water line (after pretreatment) at the minimum recommended dosage of 1ppm and maximum dosage at 15ppm, subject to inlet water quality and parameters is respect of Calcium Hardness, Iron, TDS, Alkalinity, pH and silica content. 

In case of high iron content of about 0.5 to 1.0ppm, the dosing has to be increased by 10-15ppm for stabilizing Calcium. 

At about 10-15ppm dosage our RO Antiscalant (HIGH PH) is capable of fully inhibiting iron and calcium, and silica up to 166ppm. For higher silica content RXSOL ANTISCALANT should be used.
