Storm Water Treatment

Perth Council Depot – Contaminated Storm Water Treatment

Council storm water outlet protected from traces of sheen entering the storm water system by using conventional storm water pits coupled with MyCelx filtration media inserts.

The retrofit of the existing storm water pit, a 660mm diameter pipe covered with a standard grate cover was accomplished without need to alter the existing pipe or cover and using standard fittings the retrofit was completed in a short time.

The outcome is an insert that filters water draining into the system to remove any hydrocarbons. MyCelx remains unaffected by the constant passage of clean water and is only utilised upon contact with hydrocarbons, ensuring a long and economic life of filtering at the depot.

Council Protects Lake from Contaminated Storm Water

The Council took significant steps to protect the local lake in Perth, from hydrocarbon contamination carried in with storm water from the surrounding light industrial area.

Oleology assisted by deploying MyCelx Terraguard and MyCelx Versimats in the channels leading from the outlets of each of the storm water drains into the lake.

The use of the MyCelx Terraguard booms across each of the channels acts as an “underflow weir” preventing surface flow oil and emulisifed oil and water from flowing under the boom, as would occur with conventional booms.

The second line of containment employs MyCelx Versimats, the large high floating mats are ideal for capturing the sheen should it escape the first line of containment during high flow events.

The high floating and high buoyancy booms are still capturing oil contaminants up to 12 months after initial deployment. Unlike other booms, MyCelx continues to float even when fully saturated with oil up to one year.

Each of the booms is able to capture up to 30kg of oil product giving them the highest capacity and longest deployment life of any boom available.

Port Authority

In a drive to improve storm water effluent discharging into the harbour, the Fremantle Port Authority sought assistance from Oleology to capture discharge from intermittent oil contamination of the storm water.

The MyCelx booms were deployed and fixed to move with the tide ensuring a constant guard against losses of containment entering the storm water system and spilling unchecked into the harbour.
