  • Geotextiles in Construction Dewatering

    Woven geotextiles work wonders in dewatering applications as wraps around well screens and sump pit screens. The textile can be sewn into sleeves or tubes to be slid over the well screen or sump pit framework. This technique allows the user to compensate for well screens with slots that are too large or for sump pit piping with large perforations. By adding the geotextile sleeves the user ...

  • How to Select a Dewatering Pump Supplier

    Dewatering is a requirement of many mining/quarrying or construction projects. Simply put, it is the job of eliminating or controlling the effects of water on the job site. This can mean pumping out standing water or bypassing a river, but it usually means controlling the water contained in nearby soil. Any project that requires digging into the earth (to lay foundations or sink a mine shaft) ...

  • Vertical-flow constructed wetlands as an emerging solution for faecal sludge dewatering in developing countries

    Yard-scale experiments aiming at assessing the suitability of vertical-flow constructed wetlands to dewater faecal sludge (FS) were conducted in Yaoundé (Cameroon). During 6 months, beds vegetated either with Cyperus papyrus L. or Echinochloa pyramidalis (Lam.) Hitchc. & Chase were fed under constant solids loading rates (SLR) of 100, 200 and 300 kg TS (total solids) m−2/year. ...

  • Process-based modelling of phosphorus removal in a novel constructed wetland system using dewatered alum-sludge as substrate

    A process-based model that can evaluate the transport and the fate of phosphorus (P) in agricultural wastewater was developed for a novel 4-stage dewatered alum sludge cakes (DASC) based constructed wetlands (CWs) system using STELLA software (version 9.1.4). The model considered adsorption, plant and microbial uptakes as the major forms of P involved in the transformation chains. The results ...
