Project

The University sunk a borehole to provide drinking water to the campus as an alterntive to mains water. The borehole water exceeded the EC Drinking Water Directive limits for iron and manganese and a new treatment plant was required to reduce iron to below 200 m g/l and manganese to below 50 m g/l. Whitewater reviewed the contractor's design and supervised installation and commissioning on behalf of the University.

Responsibilities

Review of process design calculations, Piping and Instrumentation Diagram (P&ID), control philosophy and specifications for major items of plant including pumps, filters and tankage.

The process route consists of aeration by compressed air injection and pre-chlorination followed by filtration using pressure filters charged with granular catalytic filter media. After filtration the water is stored prior to distribution. Filter backwash water is discharged to sewer.
