description and use

Hypersperse MDC220 is a highly effective liquid antiscalant/antifoulant developed to control scale precipitates and reduce particulate fouling within membrane separation systems. Use of this product provides longer run times and extended element life resulting in reduced operating and capital costs. Years of use in industrial applications show excellent results in membrane separation processes including reverse osmosis (RO), nanofiltration (NF) and ultrafiltration (UF) applications.
