The Overall Objective
During storm events, surface water run off would come into contact with solids from the near surface geology. These solids exhibited slow settling characteristics in the water meaning they would require chemical treatment in order to be safely discharged offsite.
Siltbuster installed 2 HB50 lamella clarifiers onsite and were able to efficiently treat the water to the required levels. The units were treating less than 10mg/litre at a flow rate of between 40-80m³/hr.
