Wastewater Equipment

Wastewater treatment has become an increasingly critical part of plant operations over the last decade. Manufacturing companies in all industrial sectors are working to reduce consumption of a finite resource, cut a dramatically increasing operational cost, and comply with tightening federal, state, and local wastewater treatment, handling, and disposal regulations.

PRAB Guardian Coolant Recycling SystemPRAB Guardian Coolant Recycling Systems 

The more you can clarify your metalworking coolants, the less waste you'll haul away. You can cut your coolant waste disposal costs up to 90% and your need to buy new coolant up to 75% with PRAB's Guardian coolant recycling system.



PRAB has been effectively handling wastewater treatment for over 35 years. We understand the value of water and have the engineering capability to help you filter, recycle, and reuse a large percentage of your currently dumped waste. Our comprehensive line of wastewater filtration equipment allows our engineers to design a system that meets the filtration needs of your facility. Most systems offer a simple payback of less than one year which means capital dollars invested are justified and recouped quickly. The PRAB wastewater filtration equipment starts as simple as a paperbed filter and magnetic separator, and moves through vacuum filtration and ultrafiltration technology. These systems, whether simple for particle removal or more complex for finite liquid/liquid separation, are all engineered based on your plant needs and your specific water analysis requirements.

PRAB, in partnership with Veolia Water Solutions & Technologies of Italy, also offers a full line of evaporation and mechanical compression wastewater filtration systems. This partnership brings two wastewater treatment experts together to offer the broadest line of equipment to meet the filtration requirements of today’s complex industrial wastewater challenges.
