RO Membranes' Protection At SWRO Facility, Asia

A seawater reverse osmosis (SWRO) facility in Asia with a 100,000 m3 per day drinking water capacity employs a multi-stage treatment process including a clarifier, disc filter, ultrafiltration (UF) membrane, micron filters, RO and post-treatment. The RO system consists of 12 skids, each treating 750 m3/hr feed water upstream of the micron filters. In 2018, the SWRO facility undertook a comparative study to evaluate the disinfection efficacy of a novel HOD™ (Hydro-Optic Disinfection) UV technology to provide enhanced protection of the RO elements and positively affect overall RO system and facility performance.

Atlantium HOD UV systems provide effective RO membrane protection by combining ultraviolet water disinfection technology with hydraulic and optic principles. The HOD UV system features the unique Total Internal Reflection (TIR) technology that recycles UV light energy, ensures homogenous UV dose distribution, provides superior power (kW) efficiency compared to traditional UV, and achieves unprecedented biofouling prevention and micro-organism inactivation.
