Published September 9, 2026. Last updated September 9, 2026. Quick Answer Industrial wastewater treatment systems combine ultrafiltration, reverse osmosis, vacuum evaporation, and automated pH adjustment in turnkey configurations to meet EPA and POTW discharge requirements while enabling water reuse. Documented results include up to 90% reductions in wastewater volume and disposal costs, with return on investment typically achieved in 12 […]

Published September 9, 2026. Last updated September 9, 2026. Quick Answer Coolant recycling systems recover 95 to 98% of metalworking coolant for reuse by combining particulate filtration, tramp oil separation, and bacterial control in a single system. Facilities typically cut new coolant purchases by 50 to 75% and disposal costs by up to 90%, with return on investment achieved in […]

Published September 9, 2026. Last updated September 9, 2026. Quick Answer Metal chip processing equipment reduces scrap volume by up to 91% and recovers up to 98% of the cutting fluid trapped in metal chips and turnings, turning a disposal cost into a documented revenue stream. Systems range from standalone crushers, shredders, wringers, and centrifuges to full crusher/wringer and shredder/wringer […]

Published September 9, 2026. Last updated September 9, 2026. Quick Answer A metal scrap conveyor is an automated system that moves metal chips, turnings, and swarf away from a machine tool to processing, storage, or load-out equipment. The right choice depends on four variables: scrap type, coolant load, throughput volume, and plant layout. PRAB offers 13 configurable conveyor types, including […]

Published 9/8/2026. Quick Answer A useful metal scrap recycling guide for a manufacturing plant covers five stages in order: sorting scrap by alloy and form at the machine, conveying it away from production without manual handling, recovering coolant or oil before the metal leaves the building, reducing volume through briquetting when the material justifies it, and negotiating with metal scrap […]

Published September 2, 2026. Last updated September 7, 2026. Quick Answer Machine shops reduce water and sewer costs primarily by treating and reusing process water and coolant on-site instead of sending it to municipal sewer, using industrial wastewater treatment systems, often built around reverse osmosis or evaporation, to recover clean, reusable water from wastewater streams and cut both discharge volume […]

Published September 4, 2026. Last updated September 4, 2026. Quick Answer Aerospace machining shops working with titanium and other exotic alloys need metal chip processing equipment built for the specific hazards and value of those chips. Titanium chips pose a fire risk and contain machining fluid that must be recovered, and the material is valuable enough that shredding and briquetting […]

Published September 1, 2026. Last updated September 1, 2026. Quick Answer: PRAB reduces equipment retrofit risk through a structured implementation process built on standardized core equipment platforms, phased installation timelines, scheduled downtime windows, pre-purchase materials and fluid testing, and the Managed Maintenance Program (MMP). Rather than a one-off custom project, a PRAB retrofit follows a repeatable, engineered sequence, backed by […]

Published August 26, 2026. Last updated August 26, 2026. Quick Answer: PRAB-built equipment carries a standard one-year warranty. For process equipment, chip processing, coolant recycling, fluid filtration, and water treatment systems, the Performantee® Guarantee is grounded in PRAB’s Test Before You Buy programs: free Materials Testing, free Fluid Testing, and the Demo Before You Buy program, each of which validates […]

Published August 13, 2026. Last updated August 13, 2026. Quick Answer Zero liquid discharge (ZLD) is a wastewater management approach in which a manufacturing facility treats and recovers essentially all of its process wastewater on site, so no liquid effluent leaves the plant as discharge. ZLD systems typically combine pre-treatment (ultrafiltration, oil-water separation), concentration (reverse osmosis), and vacuum evaporation to […]
