The Surface Water and Treatment System facility consists of lime-softened clarification, dual media filtration, ultrafiltration membrane filtration, and reverse osmosis (RO) membrane treatment. This system treats water from Lake Granbury in Granbury, Texas, which has elevated levels of chlorides ranging from 50 to 1,400 mg/L. As designed, the syste...

This paper will present bench test and full scale results and discuss key challenges of implementing bench test findings at full scale in the context of the case study demonstration tests.Utilities that treat surface water and utilities that are planning conversion from iron based coagulants to aluminum based coagulants will gain knowledge into imp...

Brazos Regional Public Utility Agency Surface Water and Treatment System completed bench test and resultant full-scale implementation for pretreatment coagulant changes from iron-based to aluminum-based coagulants. This includes optimization of clarification followed by membrane filtration and the change of operation from coagulant, flocculation, s...
