Use of Shredded Recycled Plastic as Filter Bed Packing in a Vertical Flow Filter for Onsite Wastewater Treatment Plants: Preliminary Findings

Crushed Glass as a Filter Medium for the Onsite Treatment of Wastewater

Treatment of small scale gold mining wastewater using pilot-scale sedimentation and Cocopeat filter bed system

The use of amalgamation process to recover gold from mined ores by the small-scale gold miners in the Philippines and other developing countries produces and dispose of untreated wastewater to the receiving water bodies. In this study, a field-scale filter bed system was constructed to treat heavy metal metal-laden wastewater collected from small-scale gold mining site in Paracale, Camarines No...

A survey on the performance of moving bed biofilm reactor and rapid sand filter in wastewater treatment

Moving bed biofilm reactor (MBBR) is a process in which attached growth is utilized for wastewater treatment. This process does not require sludge recycling or backwash. Activated sludge processes can be promoted to an MBBR by adding media to an aeration tank. Rapid sand filter is a physical method for the removal of total suspended solids (TSS) in advanced wastewater treatment. The purpose of ...

Treatment of Dairy Wastewater Using Pilot Scale Tricking Filter

A pilot scale trickling filter and secondary sedimentation are used to evaluate the feasibility of this process for the treatment of raw dairy waste. The BOD in the raw waste of 252 to 1200 mg/l is reduced 50-73% by a single stage and a further 17-55% by sedimentation tank. Treatment efficiencies are determined at various waste strengths and influent flow rates. With a loading rate of 5-12 kg B...

Halophyte filter beds for treatment of saline wastewater from aquaculture.

The expansion of aquaculture and the recent development of more intensive land-based marine farms require efficient and cost-effective systems for treatment of highly nutrient-rich saline wastewater. Constructed wetlands with halophytic plants offer the potential for waste-stream treatment combined with production of valuable secondary plant crops. Pilot wetland filter beds, constructed in trip...
