Over the years, we have identified that more and more of our clients are looking at ways of reducing their waste management costs. Any facility which has a wastewater treatment plant (WWTP) needs to have them emptied at regular intervals, depending on the size, usage, location, etc.

Mobile Dewatering Unit & Filter Skips

Therefore, rather than having to remove all the sludge to licensed facilities, incurring both substantial disposal costs and transport costs, we can utilise a mobile dewatering unit and filter skips as required and dewater the sludge.

Sludge dewatering is achieved by injecting a polymer into the sludge as it is being pumped through the specialised dewatering unit and into a filter skip / dewatering container, depending on the volumes of sludge. In some cases, it will suffice to just bring the dewatering unit on-site without the need for filter skips depending on the size of the WWTP.

Depending on the type of sludge, dewatering will result in volume reduction of up to 90% with a solid content ranging from 10% to 15%. The mobile dewatering units can be used to dewater sludge from WWTPs, grease traps, septic tanks, etc.

Other Dewatering Works

Enva offer a range of sludge dewatering methods for dealing with wastewater treatment, settlement pond, and filter bed waste, including the use of AVC dewatering units, mobile decanters, and mobile centrifuge plants.

Wa can also assist with the treatment and disposal of waste solids either through our Portlaoise EPA licensed facility, or through another relevant licensed facility.
