Compliance
pH Adjustment Systems help to meet zero manifesting goals and comply with Federal Resource Conservation and Recovery Act requirements plus state and local discharge regulations.
Low Maintenance
The pH neutralization system is low maintenance with minimal operator involvement.
Value
As part of the plant assessment, PRAB reviews operating costs such as electrical, water, cleaners, haul-away, manpower and regulatory compliance to get you the most value for your equipment.
Recycle and Reuse
The pH Adjustment System are engineered to pump, measure, treat, neutralize and discharge your wastewater giving you peace of mind.

Each system continuously monitors and adjusts effluent to maintain the 6.0-9.0 pH range required by EPA and POTW regulations, while automated chemical dosing minimizes reagent consumption and generates auditable compliance records.

When integrated with PRAB’s Process Water Treatment Solutions, pH-adjusted effluent can be reclaimed as process water, closing the loop on water management costs. PRAB offers continuous systems for flow rates above 10 GPM and batch systems for lower-flow or variable-discharge operations, both engineered and tested to meet site-specific permit requirements.


System Benefits

  • Predictable effluent quality — batch-to-batch consistency
  • Accurate chemical dosing through complete mixing and real-time analysis
  • Fully automated operation with minimal labor
  • Adjustable pH ranges to accommodate local municipality requirements
  • Closed-loop water reuse — treats process fluids for recirculation, not disposal
  • Reduces freshwater consumption
  • Reduced compliance risk with documented discharge events
  • Industrial-grade stainless steel construction for long service life
  • Safety & Risk Reduction — no direct handling of hazardous chemicals
  • Supports water reuse, sustainability goals, and green initiatives

pH Adjustment Systems – Key Engineering Advantages

Two-Stage Pre-Filtration

Mesh screen and automatic continuous-band filtering protect sensors and pumps, reduce maintenance frequency, and extend equipment life.

Precision Chemical Dosing

Automated acid and caustic monitoring with controlled injection based on live pH feedback prevents overfeeding and minimizes chemical spend.

Stainless Steel Construction

Industrial-grade tank with optional coatings for expanded chemical compatibility and long service life in harsh environments.

Fully Automated Operation

Automatic fluid transfer and batch discharge based on tank level and verified pH. Minimal operator intervention.

Skid-Mounted & Factory Tested

Pre-assembled for faster installation with reduced field wiring and commissioning time.

Compliance Documentation

Automated data logging of pH, volume, and time/date per batch. Email reporting and fault notifications included.

WHY BATCH PROCESSING MATTERS: Full reaction time before every discharge. Every batch is verified before drain or recirculation — less chemical waste, less freshwater draw, water reuse ready.

How Batch pH Adjustment Systems Work

PRAB batch pH neutralization systems treat acidic or alkaline water streams for two outcomes: compliant discharge and direct return to your manufacturing process. Unlike continuous-flow systems that rely on aggressive dosing, PRAB’s batch design delivers uniform, fully verified water quality — so treated water is ready for drain or recirculation every cycle.

 

01 Pre-Filtration

  • Mesh screen removes large solids
  • Automatic indexing drum filter (50-micron) captures fines
  • Protects pumps, probes, and downstream components
02 Controlled Batch Neutralization

  • Wastewater rapidly fills the stainless steel reaction tank
  • Automated dosing of acid or caustic chemistry
  • Continuous pH monitoring ensures precise batch control
03 Verification, Discharge or Reuse

  • Effluent confirmed within the targeted pH range
  • Neutralized batch routed to drain or returned to the manufacturing process
  • Process data logged for compliance documentation every cycle

Building the Closed-Loop Factory – Why Infrastructure Matters More Than Ever

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 […]
