The Rochem Separation Systems, Inc. (Rochem) Disc TubeTM Module (DTM) technology is an innovative membrane separation process. It is designed to treat liquid waste that is higher in dissolved solids content, turbidity, and contaminant levels than waste treated by conventional membrane separation processes. According to the technology developer, Rochem, the innovative DTM design reduces the pote...

The biological treatment of ammonia-rich landfill leachates due to an inadequate C to N ratio requires expensive supplementation of carbon from an external carbon source. In an effort to reduce treatment costs, the objective of the study was to determine the feasibility of nitrogen removal via the nitrite pathway during landfill leachate co-treatment with municipal wastewater. Initially, the la...

A common failure mode for landfills is clogging of the leachate collection system. Based on the studies of clogging about landfill leachate collection system, the influence factors about clog were comprehensively and systematically analyzed .The results show that calcium is the dominant mineral of the dry mass of clog material, and CaCO3 is the main component of the clog. The growth of biomass,...

The large number of municipal solid waste (MSW) landfills and the many hazardous materials which they contain pose a serious threat to both surrounding environment and human populations. Once waste is deposited at the landfill, pollution can arise from the percolation of leachate to the porous ground surface. Contamination of groundwater by such leachate renders it and the associated aquifer un...
