WSI International products

Our Containerized Systems are wastewater treatment systems fit into a container to allow a natural movement for remote locations and emergency needs. Designed with maximum efficiency in mind, these systems are fully equipped with the needed with controls and are ready to treat municipal wastewater.

WSI belt presses are designed for heavy mud and sludge applications. Our presses are a perfect fit for Oil and Gas Operations. They come skid mounted and can recycle water from the DAF to wash down the belt. They can operate as a complete stand-alone unit, to dewater at multiple sites. Each belt press come pre-assembled  and tested. They are capable of treating 7 barrels a minute of sludge.

Our module system offers a complete solution to any Oil and Gas wastewater stream. They are prefabricated and ready to deploy. Most configurations have a chemical treatment module, DGF/DAF module and a dewatering module. They can be rearranged on the fly, depending on the treatment requirements. Each module has integrated control that intelligently "talk" to each other to optimize effluent quality.

The R-75 DAF was originally designed for use in the mining and the oil & gas industry. Over the past couple of years, it`s become apparent that it`s robust heavy-duty frame and integrated components are perfect for emergency industrial pretreatment scenarios. We`ve deployed the R-75 to several customers that were out compliance on their discharge permits. The DAF is capable of running autonomously and can remove 99% of solids.The DAF can process 500GPM of water.

WSI has been designing and building Belt Filter Presses for over 12 years. Our belt press uses industry standards as well as proprietary technology. All of our presses have five major components; a headbox for optimal sludge flocculation, a gravity section to thicken the sludge, an adjustable wedge section to allow for maximum dewatering, an “S” section to permit a gradual increase in pressure and a cake doctoring section to remove the sludge from the belt. Each section is custom designed to meet or exceed the demands of the project. 

The DAF unit acts to remove the suspended solids (TSS) from the wastewater source. The DAF pump recirculates DAF effluent and flash mixes it with ambient air (aspirated on the suction side of the DAF pump). The air dissolves into the effluent under the pressure of the pump.

The skimmer system is comprised of two parallel lengths of ultraviolet stabilized glass reinforced Nylon 6/6 chain with stainless steel paddles and buna rubber wiper assemblies.
