MANCHESTER, UK – BWA Water Additives has introduced Flocon 885, the first polymer to provide a biodegradable option for cost-effective control of carbonate and sulfate scales on reverse osmosis systems.
Nozi Hamidi, BWA Water Additives vice president of marketing, said: “Flocon 885 is a specialized organic chemistry that is highly effective in controlling deposition of inorganic scale-forming salts on membrane surfaces… Flocon 885 is the only product that is readily biodegradable in both sea water and fresh water conditions. This is important to offshore producers who are phasing out the use of chemicals targeted for substitution by CEFAS standards.”
BWA’s Flocon 885 breakthrough provides a biodegradable option to offshore producers who typically use phosphonate based antiscalants to clean membrane desulfination units. Starting in 2015, the use of chemicals such as certain phosphonates in applications where there is discharge to seawater will be limited due to their environmental profile.
The company says the antiscalant was developed to overcome the environmental profile issues of toxicity to aquatic organisms, bioaccumulation, and biodegradation.
