How are industrial wastewater treatment systems customized for...

Custom system design begins with an analysis of industrial wastewater composition, flow rate, and site goals. Aerospace may need heavy-metal removal, plating may require cyanide destruction, and battery recycling may need acid and fluoride treatment. PRAB’s engineers combine UF, RO, evaporation, pH control, and chemical treatment for industry-specific solutions, often delivered in modular, skid-mounted configurations for quick installation. Industry Examples […]

What’s involved in achieving Zero Liquid Discharge (ZLD)?

ZLD (Zero Liquid Discharge) systems recover nearly all water from industrial wastewater, producing reusable distillate and a concentrated residue. This is accomplished through vacuum evaporation, crystallization, advanced filtration, and sometimes membrane pre-treatment to maximize recovery and reduce environmental impact. PRAB Highlight: PRAB’s Evaled® vacuum evaporators help meet ZLD goals by efficiently concentrating wastewater and producing high-purity distillate. These units are […]

How can ultrafiltration improve process water quality and...

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 […]

How do I select the right metal scrap...

Matching metal scrap conveyor technology to material and coolant type is critical. Consider scrap size (fine chips vs bushy turnings), material (aluminium vs steel vs cast iron), coolant content (wet vs dry), and elevation/incline. Metal Scrap Conveyor Examples: Steel belt conveyors perform well in both wet and dry operations. Oscillating conveyors excel at handling wet, abrasive chips. Pneumatic systems provide […]

How do metal scrap conveyors improve workplace safety...

Metal scrap conveyors eliminate manual scrap handling, reduce forklift traffic, spill risks, and operator injuries. They improve workplace safety by keeping floors cleaner, reducing slip hazards, and improving workflow efficiency. PRAB conveyor systems have helped facilities cut forklift scrap transport by up to 80%, reducing accident risk and freeing floor space for production. In one metal stamping plant, installation of […]

How do conveyors integrate with metal chip processing...

Conveyors integrate with metal chip processing and coolant recycling systems by automatically moving metal chips and swarf to downstream equipment such as crushers, wringers, centrifuges, or briquetters. This seamless flow allows for fluid reclamation, cleaner scrap handling, and more efficient scrap load-out. PRAB engineers metal scrap conveyors to function as part of complete chip and fluid management cells, with built-in […]

What features improve conveyor durability and reduce maintenance...

Durable metal scrap conveyors are engineered with abrasion-resistant components, heavy-gauge steel, sealed bearings, and bolt-free flight connections. Metal scrap conveyor durability in harsh metalworking environments is required to reduce downtime and extend lifespan. Factors like temperature resistance, magnetic properties, incline, and maintenance requirements should be considered. PRAB incorporates AR-steel wear bars, NEMA-rated motors, and replaceable side wings in its steel […]

What types of scrap conveyors are used in...

A metal scrap conveyor is a system used in manufacturing to transport metal chips, turnings, swarf, and other waste for recycling or disposal. Common types include steel belt, oscillating, drag chain, magnetic, pneumatic, and specialty conveyors—each chosen based on scrap size, abrasiveness, coolant content, or temperature. These systems improve efficiency, safety, and the value of metal scrap while preventing downtime. […]
