Upgrade of process for tertiary treatment in purification plants
Problem / Need :
The Community of local authorities must meet the requirements for MES discharges of less than 15 mg/L for the 500 population equivalent ( HE) wastewater treatment plant ( STEP ).
Method used / Answer provided :
Installation of a casing drum filter, located after the biodisc and lamella decanter, has contributed to the reduction of suspended solids ( MES ).
The filter, made of stainless steel, is placed in an underground casing and includes all the valves required for isolation and by-pass, as well as a control and command panel.
Results
Analyses showed a positive result in terms of removal efficacy, with outlet concentrations of between 5 and 10 mg/L for a treatment flow rate of 11 m³/h. This performance indicates a high reduction in pollutants in the treated water, reflecting the efficacy of the treatment process in place.
The ability to maintain these levels of concentration at the output shows the quality of the treatment system’s performance in continuous operation at this specific flow rate.
