pH Adjustment Systems helps to meet zero manifesting goals and comply with federal Resource Conservation and Recovery Act requirements, as well as state and local discharge regulations.
Low Maintenance
The pH system is low maintenance with minimal operator involvement.
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.

Remove Heavy Metals and Organic Compounds from Wastewater to Comply with POTW Discharge Regulations

PRAB works with many customers who produce wastewater that is either too acidic or too alkaline to be discharged into the public sewer. In these cases, a reliable pH adjustment system like the fully automated, skid mounted systems offered by PRAB, could be the solution. PRAB’s pre-packaged pH Adjustment Systems treat a wide variety of industrial waste streams and are configured to neutralize and automatically adjust the pH of your wastewater, greatly reducing labor costs, eliminating accidents and potential illegal discharge violations. In straightforward terms, your system is engineered to pump, measure, treat, neutralize and discharge your wastewater, meeting POTW limitations thereby giving you peace of mind.

We start with a review of your application and then focus on which pH adjustment system will be best suited for your process. We offer customizable options that address the fact no two wastewater streams are exactly alike, which can make the selection process challenging. PRAB has streamlined this process with its new water / wastewater analysis instrumentation and complimentary lab with pH testing equipment.

pH is the measure of free acidity or free alkalinity of water. This is measured on a scale of 0-14 where solutions with a pH of less than 7.0 are acids while solutions with a pH of greater than 7.0 are bases. Bases (i.e.- Sodium Hydroxide, etc.), which are alkaline in nature are used to neutralize acids, while acids (i.e.- Sulfuric Acid, etc.) are used to neutralize alkalis.

Having a reliable, automatic monitoring system is essential to ensure that the wastewater treatment system is satisfactorily controlled to obtain the desired results. We offer a Continuous pH Adjusting System for higher flow rates (> 10 gpm) and batch pH Adjusting System for a lower flow rate (typically less than 10 gpm).

Before discharging the effluent from a wastewater treatment system to a publicly owned treatment works (or sewer) there is a specific pH range that must needs to be met for compliance as pH is constantly monitored.

Key benefits include: Reduced risk in overfeed or underfeeding of the pH adjust chemistry, assurance that you’re in compliance with the discharge requirements, improved efficiency of system operation, and reduced labor expense by not having a worker constantly monitoring.What is pH adjust?
