Retrofit Expansion Of An Ultrafiltration System Using TORAY UF Modules

The Brazos Regional Public Utility Agency (BRPUA) in Texas operates the Surface Water and Treatment System (SWATS) that treats water from Lake Granbury, fed by the Brazos River. The SWATS facility first began operating in 1988 with clarification, dual media filtration, and electrodialysis reversal (EDR). The plant was upgraded in 2001 to include ultrafiltration (UF) and reverse osmosis (RO) membrane treatment to produce higher quality effluent.

The plant's first retrofit and expansion of the UF modules and system, respectively, took place in 2008 to produce up to 10 MGD. After several years of operation, the membrane modules exhibited fiber breakage, and the utility recognized an opportunity to upgrade the existing UF system and consider room for future expansion.
