Two machines, two different jobs. Here is how to tell them apart and when to use each. A magnetic conveyor and a magnetic separator both use magnets to handle ferrous material, but they perform opposite functions. A magnetic conveyor is a material handling device that transports solid ferrous chips and parts. A magnetic separator is a fluid filtration device that […]
POTW discharge violations most commonly result from effluent pH outside the required 6.0–9.0 range, missing or incomplete discharge logs, undocumented batch events, and probe drift from inadequate sensor maintenance — any of which can trigger EPA enforcement action under 40 CFR §403. PRAB pH Adjustment Systems prevent violations by automatically verifying every batch before release, logging pH, volume, and timestamp […]
Closed-loop water management in manufacturing is a water treatment strategy in which process fluids are treated on-site and recirculated back into the manufacturing process rather than discharged to a sewer or hauled off-site for disposal — reducing freshwater consumption, eliminating discharge fees, and minimizing hazardous waste generation. PRAB pH Adjustment Systems enable closed-loop water management by neutralizing process wastewater to […]
PRAB pH Adjustment Systems automatically log pH reading, effluent volume, and timestamp for every batch discharge event, creating a complete, tamper-evident compliance record that satisfies POTW permit documentation requirements and RCRA audit trails without any manual data entry. Automated compliance reports are generated and emailed on a configurable schedule, giving EHS managers a ready-to-present audit package at any time. Learn […]
Yes — raising wastewater pH to the appropriate level (typically 8.5–10.5 depending on the metal) causes dissolved heavy metals such as zinc, copper, nickel, and chromium to precipitate as insoluble metal hydroxides that can be removed by downstream filtration or settling. PRAB pH Adjustment Systems support metal hydroxide precipitation as part of the standard batch neutralization cycle, helping facilities meet […]
PRAB’s 50-micron continuous-band filter removes fine particulate solids from incoming wastewater before it contacts pH probes or precision metering pumps — preventing probe fouling, sensor drift, and pump wear that are the most common causes of pH system downtime. The continuous-band design self-cleans automatically, eliminating the manual media replacement required by conventional drum filters and reducing overall maintenance labor. Learn […]
Industries that commonly require pH adjustment systems include metalworking, CNC machining, metal fabrication, die casting, electroplating, chemical processing, aerospace manufacturing, and food and beverage — any facility generating acidic or caustic process wastewater subject to POTW discharge limits. PRAB pH Adjustment Systems are engineered for industrial wastewater flows from 8,000 to 39,000 gallons per day, with configurations for both batch […]
Automated pH control eliminates the overfeeding inherent in manual neutralization by dosing acid or caustic reagent only in response to live sensor readings — stopping precisely when the target pH is reached rather than adding a fixed volume per batch. PRAB’s closed-loop dosing algorithm significantly reduces chemical consumption compared to both manual and continuous-flow systems, thereby lowering reagent costs and […]
Yes — PRAB pH Adjustment Systems support closed-loop water management by verifying treated process water to a target pH before routing it directly back into the manufacturing process, rather than to drain or haul away, eliminating disposal costs and reducing freshwater demand. PRAB systems Recycle Process Water Facilities operating under drought restrictions or zero-liquid-discharge (ZLD) requirements benefit most, as on-site […]
Batch pH adjustment systems complete the full neutralization reaction before every discharge, delivering more consistent effluent quality and lower chemical consumption than continuous-flow alternatives, which dose on-the-fly and risk under- or over-treatment at variable flow rates. Continuous-flow systems are best suited for high, constant wastewater volumes above 10 GPM where a brief residence time is sufficient for the waste chemistry. […]
