Proven Industrial Experience
PRAB‘s water treatment systems are designed to integrate with the broader manufacturing operation. Process Water Treatment Solutions address in-process fluid reuse for metalworking, plating, and food processing. Industrial Wastewater Treatment Systems ensure compliance with discharge limits for operations governed by the EPA, POTWs, or state-specific permits. For facilities targeting ZLD, EVALED® Vacuum Evaporation eliminates all liquid discharge by recovering spent fluids as high-purity reusable distillate. All systems are backed by PRAB’s Performantee® Guarantee, with documented performance data prior to shipment.
Unlike generic water treatment providers, PRAB understands metalworking fluids, tramp oils, fines, sludge generation, and the operational realities of industrial production environments.
PRAB uniquely combines:
This allows manufacturers to create more efficient closed-loop manufacturing operations that recover value from both metal scrap and industrial fluids.
Most facilities already operate legacy equipment from multiple vendors. PRAB specializes in integrating new systems into existing manufacturing environments with minimal disruption to production.
PRAB systems are designed to reduce operating costs while improving consistency, compliance, and long-term reliability. Many systems continue operating successfully for decades in demanding industrial applications.
PRAB helps manufacturers transform industrial wastewater from a costly disposal problem into a reusable operational resource.
Benefits may include:
Whether your facility needs a standalone pH adjustment system, coolant recycling equipment, or a fully integrated wastewater treatment solution, PRAB provides the engineering expertise, equipment durability, and long-term support manufacturers need to succeed.

Water Management solutions for Industrial wastewater treatment and process water treatment use a combination of physical, chemical, and biological processes to remove contaminants, meet environmental regulations, and enable reuse.
Key technologies include ultrafiltration (UF) for suspended solids and oils, reverse osmosis (RO) for dissolved salts, vacuum evaporation for Zero Liquid Discharge (ZLD), pH adjustment systems for regulatory compliance, oil-water separators, UV disinfection, and ozone oxidation for targeted contaminant removal.
PRAB designs fully integrated systems combining UF, RO, vacuum evaporators, automated pH control, and advanced oxidation in turnkey configurations tested under stringent factory conditions. These systems have achieved up to 90% wastewater volume reduction and significantly lowered chemical consumption in high-demand industries.
Ultrafiltration systems use semi-permeable membranes to separate suspended solids, emulsified oils, and fine particulates.
This process extends the life of wash water, reduces chemical use, and creates a consistent effluent stream that can be safely reused in manufacturing processes or discharged in compliance with environmental regulations.
PRAB Highlight:
PRAB’s crossflow UF systems are engineered for minimal fouling and maintenance, achieving up to 75% detergent savings and 90% haul-away cost reductions. They integrate easily with PRAB RO or evaporation systems for maximum reuse potential.
Learn About PRAB UF Systems
Custom system design begins with an analysis of industrial wastewater composition, flow rate, and site goals. Aerospace may need heavy-metal removal, plating may require cyanide destruction, and battery recycling may need acid and fluoride treatment.
PRAB’s engineers combine UF, RO, evaporation, pH control, and chemical treatment for industry-specific solutions, often delivered in modular, skid-mounted configurations for quick installation.
