Railway Station, Ipswich

The water entering the sewer system from the site was impacted by PCB’s and hydrocarbons as a result of historical spillages.

In order to comply with the discharge criteria the flow of water to sewer had to be intercepted and treated. Due to the flow volumes required two phase separation units were installed with throughput capacities of 25 cu m/hr.

The separators were capable of achieving < 50 micron hydrocarbons at the required flow rate.

To ensure compliance the separators were fitted with an additional chamber which was filled with Granular Activated Carbon.
