ultrafiltration FAQ

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.

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:

• Federal Compliance – Ultrafiltration and Reverse Osmosis systems reduce hazardous waste volumes, supporting RCRA goals and minimizing manifesting.
• State Requirements – Pilot testing and lab validation ensure systems are tailored to unique state discharge permits.
• Local POTW Standards – Automated pH Adjustment Systems continuously neutralize effluent, while Oil-Water Separators achieve effluent with <15 ppm oil to meet local oil & grease discharge requirements.
• Audit Readiness – Integrated controls provide real-time monitoring, alarms, and documentation to demonstrate compliance during inspections.

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.
