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 […]
Understanding Filter Media and Its Effects on Fluid Filtration Many buyers focus only on micron ratings when selecting filter media. But coolant filtration performance depends on several factors: Coolant chemistry Media structure (depth vs. surface filtration) Flow rate Particle size distribution Industry guidance warns that selecting filter media solely on micron rating can lead to higher operating costs and poor […]
Manufacturers continue to invest heavily in automation, machining technology, and process optimization. But as labor availability tightens and operating costs become more volatile, many plants are finding that automation alone is insufficient. This is where the “Closed-loop factory” strategy becomes important. The limiting factor is rarely the machine tool; it is the supporting infrastructure. A growing number of manufacturers are […]
When manufacturers research metal scrap handling, coolant recycling, or industrial water reuse systems, PRAB is often the benchmark for large, complex operations. That reputation is well earned. PRAB systems are widely used in centralized coolant management, plant-wide conveyor networks, ISO 14001 environmental compliance, and closed-loop water reuse—challenges typically associated with high-volume production environments. But that perception has created a misconception. […]
Paper Bed Filters remove fine metal particles and debris down to 5 microns—extending tool life, improving machining accuracy, reducing downtime, and lowering disposal costs. Why Contaminated Fluids Cost Metalworking Facilities Money Q: What problems do dirty coolants and cutting fluids cause? Accelerated wear on pumps, valves, and spindles from chips and fines. Degraded fluid quality from tramp oils and bacteria, […]
Ultrafiltration (UF) technology enables manufacturers to recycle water from tumbling and deburring processes, reducing water and sewer costs by up to 99%, decreasing chemical usage, and maintaining compliance with stringent environmental regulations—all while enhancing operational efficiency. The Manufacturing Challenge A U.S.-based die casting and fabrication manufacturer faced a significant challenge: managing wastewater from two vibratory deburring systems without exceeding local […]
A lot goes into a successful metalworking operation, from a skilled workforce to reliable equipment. Chief among these components is the effective cooling of tools and workpieces. This is where metalworking fluids like coolants and lubricants come into play, as they reduce the heat and friction produced by machining processes. Without these fluids, corrosion within the unit and raw […]
Using the PRAB Guardian to Manage Your Cutting Fluids and Fluid Filtration When machining, it is essential that shops have a thorough understanding of how to maintain their metalworking fluids properly. If they don’t, they run the risk of exposing employees to health risks, incurring avoidable costs, and harming productivity due to extended maintenance times. Here are a few […]

Research has shown that top-performing machine shops annually invest two to three times more money in capital equipment than other shops. Not coincidentally, profit margins for high performers are almost double those reported by typical shops. For all businesses, the objective is to achieve the largest possible profit margins. One way for metalworking operations to attain that goal is […]
