DuPont IntegraTec™  Ultrafiltration Modules

Explore the implementation of ultrafiltration as a pretreatment method. A multi-technology approach was selected for this treatment process, where clarified surface water is directed to the Ultrafiltration System, utilizing DuPont™ IntegraPac™ XP 77 IP* ultrafiltration modules. The recovery rate for ultrafiltration is approximately 94%. using DuPont™ IntegraPac™ XP 77 IP* ultrafiltration modules. The UF recovery is approximately 94%

FilmTec™ Reverse Osmosis Elements

UF filtrate water is directly routed to the first pass of the Reverse Osmosis (RO) System. In this process, 60% of the permeate is sent to a second RO System for a second pass, while the remaining 40% is directed to the process water tank. Both the first and second pass RO systems use FilmTec™ BW30HR-440i elements, with an individual recovery rate of 75%.
