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 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 […]
Most manufacturers using TiO₂-based coatings, paints, or pigments are generating titanium dioxide wastewater. Most don’t realize it until there’s a compliance problem. Titanium dioxide is the most widely used pigment in industrial manufacturing — present in automotive primers, aerospace coatings, industrial finishes, and plastics. When those processes generate wash water, rinse water, or process effluent, TiO₂ is present. The challenge: […]
For most manufacturers, the conversation around wastewater pH starts and ends in the same place: don’t violate the permit. And that’s fair. POTW discharge compliance is non-negotiable. The consequences of getting it wrong — surcharges, permit violations, forced shutdowns — are real and expensive. But here’s what a lot of plants are missing. A well-engineered automated pH adjustment system doesn’t […]
The U.S. manufacturing sector is running into a wall it cannot drill through, outsource away, or ignore any longer: water scarcity. As of early 2026, more than half of the contiguous United States is experiencing some degree of drought, and in the most production-intensive industrial regions — Phoenix, Las Vegas, Corpus Christi, San Antonio, and California’s manufacturing corridors — the situation […]
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 […]
Why pH Control Systems Matter in Industrial Wastewater Every manufacturing process that uses water, whether for cooling, cleaning, plating, or machining, creates wastewater with fluctuating pH. Those fluctuations can result from spent coolant, tramp oils, cleaners, or metal-bearing fluids. When pH drifts outside the EPA- or POTW-required 6.0–9.0 range, facilities risk heavy surcharges, permit violations, or even forced shutdowns. That’s […]
