Waterworks supplied a 25 m3/day package treatment system that was barged to a remote coastal island off British Columbia for treating effluent from a directional drilling operation camp. Treated effluent was discharged to a protected shell fish rich marine bay and had to achieve strict discharge requirments.
The unit had to be very small for easy transportation and operate with minimal operator attention. Flow volumes and strengths swing wildly throughout the day as did contaminant levels.
Influent was equalized and screened through a static screen, then treated in a Waterworks Trickling Filter Extended Aeration (TFEA) unit. The effluent was disinfected before discharge.
The treatment plant was only 6 feet by 16 feet in plan area.
