Powdered activated carbon.
A complete small treatment plant made at a factory and placed on site. For wastewater treatment, the package plant may contain primary sedimentation, aerobic biological treatment (e.g. acti vated sludge or rotating biological contactor), secondary sedimentation and sludge storage. The small local nature of the population that is served by a package plant can result in large variations in flow giving hydraulic shock loads to the treatment processes and so flow balancing may be required before treatment. Periodic substantial discharges of disinfectants or detergents associated with regimented cleaning at a hotel, caravan park, etc., can give rise to problems with the biological treatment processes. Other problems include excessive discharge of grease (e.g. from onsite restaurants) and a lack of trained personnel leading to poor maintenance of the plant.
