Sludge drying reed beds: full- and pilot-scale study for activated sludge treatment.
Sludge drying reed beds have been used for dewatering and mineralization of sludge since the beginning of the 90s, but their insufficient performances in terms of Dry Matter [DM] content and mineralization of the sludge have made necessary new studies. Therefore, 8 pilots of 2 m2 each and a full-scale plant (13,000 p.e, 8 beds of 470 m2 in operation for 4 years) have been monitored to examine t...
متن کاملTreatment of septage in sludge drying reed beds: a case study on pilot-scale beds.
French legislation requires the control of private on-site sanitation systems by local authorities. This will result in a large increase of the quantity of sludge from septic tanks to be treated. Nevertheless, large wastewater treatment plants are not systematically able to treat this sludge because they may have reached their nominal load or they are not so numerous in rural zone to avoid too ...

متن کاملSludge Dewatering and Mineralization in Sludge Treatment Reed Beds
Sludge Treatment Reed Beds (STRBs) are widely used in Northern Europe to dewater and mineralize surplus sludge from activated sludge systems used to treat urban domestic sewage. STRBs are low-technology, energy-efficient, and do not require addition of chemicals. They dewater and stabilize the sludge and produce a final product that can be safely used as a fertilizer for agricultural crops. Lon...
متن کاملSludge Treatment in Reed Beds Systems – Development, design, experiences
There are important differences in the environmental perspectives and costs involved in mechanical sludge dewatering followed by disposal on agricultural land compared to reed bed sludge treatment. The effect on the environment of the operation of a Sludge Treatment in Reed Beds system is seen as quite limited compared to traditional sludge treatment systems such as mechanical dewatering and dr...
