  • Common Treatment Technologies for Inorganics in Soil, Sediment, and Sludge

    The most commonly used treatment technologies for inorganics in soil, sediment, and sludge include solidification/stabilization (S/S), excavation and off-site disposal, and acid extraction. These treatment technologies are described briefly below. Solidification processes produce monolithic blocks of waste with high structural integrity. The contaminants do not necessarily interact chemically ...

  • Retainment of the antimicrobial agent triclosan in a septic tank

    Laboratory experiments were conducted to investigate the fate of the antimicrobial agent triclosan (TCS) in a conventional septic tank. The main mechanism of TCS removal from wastewater was identified to be rapid TCS sorption to suspended particles followed by settling of these particles to the bottom of the septic tank. Sorption to particles was completed within minutes while the settling took ...

  • Freezing/thawing effect on sewage sludge degradation and electricity generation in microbial fuel cell

    The effect of sludge freezing/thawing on its disintegration and subsequent use as substrate in a microbial fuel cell (MFC) was investigated to enhance organic matter degradation and electricity generation. Experimental results indicated that long freezing time (more than 48 h) was effective in disintegrating the sludge collected from the secondary sedimentation tank of a wastewater treatment ...

  • Mass balance analysis of triclosan, diethyltoluamide, crotamiton and carbamazepine in sewage treatment plants

    The behavior of antibacterial triclosan, insect-repellent diethyltoluamide (DEET), anticonvulsant carbamazepine, and antipruritic crotamiton was investigated at two sewage treatment plants (STPs) to clarify their complete mass balance. Twenty-four-hour flow-proportional composite samples were collected from the influent and effluent of primary and final sedimentation tanks, a biofiltration tank ...

  • Pilot-scale fluoride-containing wastewater treatment by the ballasted flocculation process

    A pilot-scale ballasted flocculation system was used to remove fluoride from one type of industrial wastewater. The system included the formation of calcium fluoride (CaF2) using calcium hydroxide followed by coagulation sedimentation. Calcium fluoride was recycled as nuclei for enhancing CaF2 precipitation and as a ballasting agent for improving fluoride removal and flocculation ...

  • Full scale municipal implementations of the Agar IFAS process for municipal wastewater treatment

    Wastewater treatment plant retrofits worldwide are motivated by two main developments: a. Changes in effluent quality regulations, either to more stringent BOD/TSS requirements, or to include nutrient (N and P) removal b. Increase in flows to existing plants, due to either population growth or to expansion of sewerage systems One process capable of giving a cost-effective solution for these two ...

  • Municipal waste water treatment plant case study

    A municipal WWTP in the North of England was experiencing significant problems with accumulations of FOG in the Wetwell at the head of the treatment plant. The FOG would form a solid cap over the well several feet thick. This put considerable strain on the pumping gear, interrupted the performance of the float switches and required regular manual intervention from the staff. High costs were also ...

  • Water treatment case study

    Wastewater is any water that has suffered in quality by human intervention. Often, wastewater is being treated for re-use as drinking water or for other purposes. As high levels of nutrition are available in these waters, algae may grow rapidly as well as other micro-organisms such as bacteria. Algae can compete for nutrients against the bacteria in charge of sludge reduction and can also clog ...
