PacTec’s dewatering filters automatically separate solid and liquid during a sludge dewatering process. Also known as sediment filters, they are placed in dewatering containers- meaning no need for additional dewatering boxes. This streamlines the filtering process in a way that can save your company money. As a result of this filtration, the compacted, dry waste has less weight and volume- ultimately minimizing waste disposal costs.
Operations that can benefit from using these specially designed filters include:

PacTec offers various dewatering filter liners to fit most common 20-yard and 30-yard dewatering boxes. We also offer W-shaped dewatering filters to fit boxes of that unique design.
PacTec utilizes many fabrics to effectively capture solids during the dewatering process, regardless of your water content. We offer micron ratings from 50-micron to 260-micron to meet your waste stream needs. If you are unsure which option is best, contact a member of our team and we will gladly assist you.
PacTec offers many dewatering filter sizes, meeting the needs of most dewatering boxes. However, if your box dimensions are uncommon- give us a call to inquire about exact sizing and fit. If needed, we can custom-manufacture liners for you.
Yes, PacTec’s dewatering liners are very easy to install, and can be done quickly, by one person and from the outside of the box. To see just how easy it is done, we’ve created this installation video.
PacTec utilizes various materials to fabricate dewatering filters, but the most common are from a non-woven polymeric material. For a larger micron rating, we use mesh screens and woven materials with larger openings. If you need samples to test your waste stream, you can request these by contacting a member of our team.
Most customers use dewatering filters one time only, as they tend to blind off (where solids become lodged in all openings) as they fill, rendering their dewatering capabilities null once complete. Knowing this, PacTec makes them an affordable component of your dewatering processes.
PacTec’s dewatering filters are the ideal solution for dewatering many waste streams, including industrial sludge pits, cooling tower sludge, paint sludge, sump cleaning, and more. They are also heavily used in construction dewatering and industrial and refining processes.
Dewatering filters are often a much more cost-effective method of dewatering when compared to filter or belt press and eliminates the need for additional solids containment.
The Future of Biosolids Management: How to Stay Compliant with PFAS Regulations
The landscape of biosolids management is changing rapidly due to increasing scrutiny of PFAS contamination in biosolids. Land spreading bans in states like Maine and growing concerns about groundwater contamination mean more wastewater treatment plants (POTWs) may need to turn to Subtitle D landfill disposal.
But landfill disposal comes with challenges:
· Biosolids must pass the US EPA Paint Filter Test before being accepted for disposal.
· Excess moisture content can increase landfill tipping fees and transportation costs.
· PFAS-contaminated biosolids need containment solutions to reduce leachate risks.
Without the right dewatering solution, your facility could face landfill disposal restrictions, higher disposal costs, and operational impacts.
The Solution: PacTec’s Dewatering Solutions for PFAS-Contaminated Biosolids
At PacTec, we provide cutting-edge biosolids dewatering solutions that help wastewater treatment plants comply with US EPA and State landfill requirements while reducing transportation and disposal costs.
How Our Dewatering Solutions Help Your Facility:
-Ensure Compliance – Our dewatering filters and bags help biosolids meet the US EPA Paint Filter Test requirements, making them eligible for landfill disposal.
– Reduce PFAS Risks – By removing excess water, we help minimize leachate concerns in Subtitle D landfills.
– Lower Costs – Reducing water weight in biosolids means lower transportation and tipping fees.
– Easy to Implement – Our solutions integrate seamlessly into existing biosolids processing workflows.
With PFAS restrictions tightening, wastewater treatment plants must take action now to secure cost-effective, compliant biosolids management strategies.
