DuraSlick* RO is a family series of membrane elements engineered for use with fouling-prone brackish water applications and industrial effluent treatment before reuse or discharge. DuraSlick RO features a proprietary thin-film innovative low fouling membrane, providing
higher hydrophilicity, a smoother membrane surface and lower membrane charge.
Retrofitting exiting systems with the DuraSlick RO will extend operating time between required cleanings, which in turn reduces downtime and expenditures on required chemicals.
