Written by Paul Montgomery, Published July 31, 2026 | Last updated July 31, 2026 Quick Answer: Automated pH adjustment systems, also called pH neutralization systems or pH adjusters, continuously monitor acidic or alkaline wastewater and dose acid or caustic chemistry to bring it into the 6.0 to 9.0 pH range required for compliant discharge. Beyond compliance, batch-based systems verify every […]
Published July 30, 2026 | Last updated July 30, 2026 Quick Answer: Tramp oil is unwanted hydrocarbon-based oil, such as way lubricant, hydraulic fluid, or rust-preventive coating, that leaks or migrates into metalworking coolant and washwater. It floats, disperses, or emulsifies in the fluid, where it reduces cooling performance, feeds bacterial growth, shortens tool life, and drives up disposal costs. […]
Published July 20, 2026. Last updated July 20, 2026. Quick Answer: There is no single “best” industrial wastewater treatment system. The right system depends on your wastewater composition, flow rate, and discharge or reuse goals. Most manufacturers combine two or more of five core technologies: ultrafiltration, reverse osmosis, vacuum evaporation, automated pH adjustment, and oil-water separation. PRAB customer installations have […]
Published July 20, 2026. Last updated July 20, 2026. Quick Answer: A coolant recycling system typically reduces new coolant purchases by 50 to 75 percent and cuts coolant disposal costs by up to 90 percent, while recovering 95 to 98 percent of metalworking coolant for reuse. Most manufacturers see full return on investment within 6 to 18 months, with high-volume […]

Quick Answer You turn metal scrap and coolant recycling into a connected automation system by treating conveyors, chip processors, coolant recycling units, and wastewater treatment as one engineered line rather than separate equipment purchases. This means specifying PLC […]

Quick Answer What is a closed-loop metalworking system? A closed-loop metalworking system is a plant-wide architecture in which metal chips, coolant, and wastewater are continuously captured, processed, and returned to productive use rather than being discharged or hauled away as waste.

Quick Answer Does the material being machined affect which metal scrap conveyor or chip processing system I need? Yes, significantly. Chip morphology, bulk density, abrasiveness, and coolant affinity vary widely by material. Aluminum produces fine, stringy chips with high coolant retention […]

Reviewed by Mike Proos | Published July 2, 2026 | Last updated July 2, 2026 Quick Answer: A wringer uses centrifugal force to fling cutting fluid off metal chips, recovering fluid that would otherwise leave with the scrap. The recovered fluid is mechanically separated, not chemically cleaned, so it can carry fines […]
