RO Membrane Scale Inhibitor - Scale inhibition processes have been studied in detail. From this work, it has been determined that ‘Threshold’ is the key mechanism in the prevention of scale formation in membrane systems.

ROCscale 51 reduces the risk of scaling and eliminates the use of hazardous acids, resulting in efficient plant operation with the highest possible conversion rate. It is, therefore, a more cost-effective alternative for membrane protection than pH control or ion exchange softening.

ROCscale 51 is a super-threshold RO membrane scale inhibitor able to stabilise a wide range of supersaturated salt solutions, thereby preventing precipitation on the membrane surface. This property allows engineers to design RO systems to successfully operate at higher recoveries than systems that do not utilise this technology. Equipment manufacturers that design systems to operate at higher recoveries have a significant advantage over their competitors because they can offer the end user benefits such as: 

• Improved cost effectiveness.
• Less feedwater required.
• Less concentrate for disposal.
• Less chemicals to be used.
• Better environmental acceptance of concentrate discharge.

Product benefits 

• Highly effective antiscalant across a broad spectrum of waters.
• Minimises scaling and reduces the frequency of membrane cleaning.
• Will usually replace the need for acid addition.
• Low dose rate gives a highly cost-effective solution to scale control.
• Compatible with all membrane types.
• Effective iron and manganese sequestrant.
• More stable and effective than sodium hexametaphosphate and most polymers.
• Enables systems to work at enhanced rates of recovery.
• Classified for use in producing potable water including ANSI/NSF Standard 60, Kiwa-ATA and DWI certification.
