What Should Be in a Manufacturer’s Metal Scrap Recycling Guide?

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 […]

How Can Machine Shops Reduce Water and Sewer Costs?

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 […]

What Systems Are Suitable for Aerospace Alloys and Titanium Chips?

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 […]

How Does PRAB Make Equipment Retrofits Predictable Instead of Risky?

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 […]

What’s Covered by PRAB’s Warranty, Performantee Guarantee, and Managed Maintenance Program?

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 […]

What Is Zero Liquid Discharge (ZLD) and How Does It Work?

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 […]

How Does Industrial Wastewater Treatment Work?

Published August 13, 2026. Last updated August 13, 2026. Quick Answer Industrial wastewater treatment uses a combination of physical, chemical, and biological processes to remove contaminants from manufacturing wastewater, enabling safe discharge or reuse. A typical system combines oil-water separation, ultrafiltration, reverse osmosis, automated pH adjustment, and, for high-strength waste streams, vacuum evaporation. The right combination depends on the plant’s […]

What Is the Difference Between a Tramp Oil Separator and a Coolant Recycling System?

Published August 13, 2026. Last updated August 13, 2026. Quick Answer A tramp oil separator is a single-purpose device that removes floating or dispersed hydraulic oil and lubricants from coolant. A coolant recycling system is a complete, multi-stage plant that performs oil removal, then adds particulate filtration, concentration control, and bacteria control so the coolant can be pumped back into […]

Safety Guidance for Magnesium, Titanium, and Mixed-Alloy Chip Processing

Published August 11, 2026. Last updated August 11, 2026. Quick answer: PRAB engineers metal chip processing, conveying, and fluid recovery equipment for magnesium, titanium, and mixed alloy applications in line with NFPA 484 and its successor consolidated standard, NFPA 660, the governing framework for combustible metals handling. That means application-specific system design, wet-type handling approaches where fine particulate risk is […]

How Does PRAB Integrate Systems for Coolant Recycling, Filtration, and Metal Scrap Handling Equipment With Existing Facilities?

Published August 11, 2026. Last updated August 11, 2026. Quick answer: PRAB integrates coolant recycling, fluid filtration, wastewater treatment, and metal scrap conveying equipment with existing plant systems through a structured, phased framework, not a one-off install. The process begins with an application study and controls assessment, moves through a documented interoperability plan covering supported PLCs, robotic cells, and OEM […]
