  • What is scale inhibitor?
  • Scale inhibitor is an indispensable chemical in water and non-water segment. They aid in keeping the membranes from fouling so that the water will flow smoothly through. It is highlighted that appropriate selection or rather optimization of RO configuration can result in savings of up to 5 % as compared to conventional design.
  • How do you use a scale inhibitor?
  • The inhibitor must be present in the water continuously so that it is available to inhibit the growth of each scale crystal as it precipitates from water. Either continuous chemical injection or a “squeeze” treatment, which provides a constant supply of inhibitor to the system between treatments, must be used.
  • Are chemical treatments for scale control a good idea?
  • Conventional chemical treatments for scale control are expensive and may cause health concerns and ecological implications. Non-chemical water treatment technologies such as electromagnetic field (EMF) are attractive options so the use of scale inhibitors, anti-scalants, or other chemical involved processes can be avoided or minimized.
  • Which anti-SCALANT is effective in preventing Caso 4 scaling?
  • Anti-scalants are chemicals such as organophosphonate, polyphosphate- or acidic polymers like polyacrylic acid 118, 119. Corbett 57 reported that EMF was invalid in preventing CaSO 4 scaling at 91% water recovery in RO system, while the application of anti-scalant sodium hexametaphosphate was successful in avoiding scale at 93% water recovery.
