Challenge

A recently commissioned water treatment plant was oversized compared to the town’s water demand and operated only for a couple of hours in a 24-hour production cycle, leading to the UF membrane fouling, Disinfection issues in potable water and critical alarms during startup.

Solution

Sapsorb Water Services had a technical support contract with our client and was engaged to provide the best solution for this challenge. After reviewing the control philosophy of the entire conventional treatment and UF system, the system solution included reducing the raw water flow to match the peak demand and programmable changes to the UF system by splitting the UF trains into two to operate as duty/standby

Results

The systems operate for a longer duration, eliminating the membrane fouling and disinfection issues. Also, all the alarms were eliminated, and the plant operated seamlessly to supply adequate quality water to the community.
