Membrane Upgrades to Address Aging Water Treatment Infrastructure Challenges in a Small System

Deteriorating water treatment infrastructure and high levels of organics in the raw water created challenges for the Village of Hines Creek in satisfying ESRD?s more stringent treated water quality standards. An assessment of the facility identified major process components that needed upgrades including pre-treatment/sedimentation, filtration, and organics removal processes. Short-term filtration improvements were implemented to address the aging filtration infrastructure. Long-term, upgrade considerations included existing asset utilization, addressing regulatory pressures, operability, and treatment robustness. The adopted upgrade strategy of UF and NF membranes assured that the system is versatile enough to meet current and future regulatory challenges.
