  • 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) ...

  • Geotube Dewatering Technology is Sound Application for Remediation of Fox River Cleanup Site - Case Study

    Technology Allows Processing of Large Volumes While Retaining Impurities and Making Collection and Disposal Easier. Environmental remediation projects are often complicated, challenging—and huge. In fact, a number of remediation jobs that should be done have been delayed because there was no economical way of getting them accomplished. But that could be changing, thanks to a ...

  • Important things to consider when you have to treat dewatering discharge water at your site

    In many cases when you have to dewater an area of a construction or remediation site to do an excavation or other subsurface work, the water is clean and can be easily discharged without treatment. However, in some cases the soil and groundwater are contaminated, and if dewatering is required, it is highly likely that the discharge water will be contaminated and will require some type ...

  • Aggressive dewatering aids concrete rehab at Abitibi

    An enormous volume of water passes through the Abitibi Canyon Generating Station every hour of every day. In order to complete critical concrete repairs on the hydro power station, general contractor The Barclay Construction Group needed to find a way to pump and discharge almost 30 million gallons of water in a 500-metre section of the river upstream from the station in under 30 hours. Aquatech ...

  • Processing Wastewater Sludge Using Dewatering Containers

    The relative cost of dewatering equipment varies widely and is directly related to the processing rate. For smaller utilities that need to dewater sludge in batches, dewatering containers are an alternative that can be relatively inexpensive and simple when compared to other technologies on the market. The most common type of dewatering container is based on a roll-off box design, although any ...

  • Dewatering of moist sediments and soils for application to RaPID Prep AND RaPID assays procedures

    BACKGROUND INFORMATION: High moisture content (>30% by weight) can significantly lower concentrations of analytes detected in the RaPID Prep soil methods. In these methods, water associated with a sample will increase the volume of the extraction solution (liquid phase) and decrease the amount of soil (solid phase) in a weighed sample. In some cases, water may also decrease the ...


  • How to Deal with Oils When Treating Contaminated Construction Dewatering Water

    Oils are defined as organic materials that are not completely dissolved in water and present in the forms of sheens, globules, droplets. If present at a construction dewatering site, oil will most likely need to be removed from the contaminate water before discharge in order to meet the discharge limits for oil & grease (O&G) and/orspecific contaminants of concern (COC) that oil may carry ...
