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.

Automated pH adjustment systems continuously monitor and regulate pH levels in wastewater to meet local discharge requirements. By reducing manual intervention, they ensure consistent compliance, optimize chemical usage, and improve the efficiency of treatment processes across a wide range of industries.
PRAB designs and integrates automated pH neutralization systems as part of complete wastewater treatment packages for industries such as metal finishing, aerospace, battery recycling, and pharmaceuticals. These systems range from acid neutralization for plating operations to advanced real-time pH control for manufacturing lines, providing consistent, reliable results.
Ozone and UV (Ultraviolet) systems destroy bacteria, viruses, and organic contaminants without adding residual chemicals, making them ideal for reuse and high-purity applications.
PRAB integrates ozone and UV into closed-loop systems for parts washing, plating, and other high-purity industrial processes.

Oil-water separators remove free and some emulsified oils from process water, protecting downstream filtration equipment and improving discharge quality.
PRAB offers oil-water separation as part of integrated treatment packages, improving UF membrane life and system efficiency.
PRAB Oil-Water Separation Solutions
Membrane filtration (UF, nanofiltration, RO) produces high-quality water for reuse or discharge, reduces chemical use, and meets stringent environmental regulatory standards.
PRAB’s membrane systems are designed for industrial durability, integrating with evaporation or chemical treatment for complete solutions.
Resources:
Industrial wastewater treatment systems support regulatory compliance by removing contaminants, adjusting pH, reducing oil and grease, and lowering dissolved and suspended solids to meet federal, state, and local discharge standards.
These systems are designed to align with regulations such as the U.S. EPA’s Clean Water Act, Resource Conservation and Recovery Act (RCRA), state-level discharge permits, and local Publicly Owned Treatment Works (POTW) limits. By integrating technologies like ultrafiltration, reverse osmosis, oil-water separation, and automated pH adjustment, facilities ensure effluent quality remains within mandated thresholds—helping avoid fines, protect community infrastructure, and pass environmental audits.
PRAB’s industrial wastewater treatment solutions are engineered specifically to help manufacturers meet or exceed environmental regulatory compliance requirements:
By combining engineered equipment, pilot testing, and automated controls, PRAB systems give manufacturers confidence in regulatory compliance while also reducing costs through water reuse and zero-liquid-discharge strategies.
EPA pretreatment regulations require industrial wastewater discharged to a Publicly Owned Treatment Works (POTW) to maintain a pH between 6.0 and 9.0. Discharges below pH 5.0 are specifically prohibited under 40 CFR §403.5(b)(2). PRAB systems verify every batch within this range before discharge is permitted.
Yes. PRAB pH adjustment systems are configurable for closed-loop water management, routing treated water directly back to the manufacturing process rather than to drain. This reduces freshwater consumption, cuts fluid disposal costs, and supports sustainability goals. End-of-life coolants, wash water, and process fluids can all be treated for recirculation.
PRAB’s automatic 50-micron continuous-band filter is the second stage of the two-stage pre-filtration system. It continuously removes fine particulates that could foul pH probes, damage metering pumps, or interfere with chemical dosing accuracy — extending equipment life and reducing maintenance frequency compared to conventional drum filters.
Yes. In metal-bearing wastewater streams, raising the pH to the appropriate level causes dissolved metals to precipitate as metal hydroxides for downstream removal. PRAB systems support metal hydroxide precipitation as part of the standard batch neutralization cycle, helping facilities meet both pH and metals discharge limits simultaneously.
