A Met-Chem pH Adjustment and Neutralization System will regulate pH levels for your industrial wastewater stream. Each system is custom engineered to fit the exact needs of your industrial application.
Met-Chem pH Adjustment Systems can handle flows from 1-10,000 GPM, and they are designed with two stages of treatment. Stage one handles the bulk of the pH adjustment, while stage two allows for fine adjustment to hit the targeted pH level. Whether acid is needed to lower the pH or a caustic is needed to raise the pH, a Met-Chem pH Adjustment System will target your desired pH range.
The standard tank construction for the Met-Chem pH Adjustment Systems are polyethylene tanks. These tanks are mounted onto a skid for easy shipping and installation. We are also happy to offer fiberglass tanks for applications with elevated temperatures or other corrosive conditions.
Met-Chem pH Adjustment Systems are automated with a Met-Chem Control Panel. This includes controlling the mixers, monitoring the pH, adding chemistry, and out of compliance alarms. Each system will be designed and automated to fit your specific wastewater application.
Met-Chem pH Adjust System has the ability to add an acid or a caustic. This allows for precise pH control and application of the chemistry. Both tanks contain pH probes that are constantly sending the precise pH levels to our Met-Chem Control Panel. This panel will automatically adjust the dosing rates of the chemical metering pumps. Both tanks also include mixers, with 316SS shafts, that are also controlled by the Met-Chem Control Panel. If no solids are present in the waste stream and the only discharge requirement is for the pH to be within a specific range, then the flow out of pH adjust tank #2 can go right to the city sewer.
Met-Chem can also provide a final monitoring station which can include a sampling port, pH recording, and out of compliance alarms. This final monitoring station will ensure all flows from your facility to the drain are within your discharge permitted range.
If solids are created by the pH neutralization process we can send these solids to a Met-Chem Lamella Clarifier and a Met-Chem Filter Press. View a Met-Chem Wastewater Treatment System for more information on this process. The Met-Chem Lamella Clarifier will settle the solids with the use of a polymer or flocculent. The solids that are settled in the clarifier will then be pumped to a Met-Chem Filter Press for further dewatering.
For more hazardous waste streams further pretreatment steps can be added. The two most common would be adding a Met-Chem Chrome Conversion System to convert hexavalent chrome to trivalent chrome or for treating cyanide.
A Single Tank pH Batch Neutralization System can handle flows of 500 to 10,000 gallons per day. These systems can have the option to be upgraded in the future into a Batch Wastewater Treatment System that can remove solids with the addition of a Met-Chem Filter Press. This system is ideal for smaller companies that don’t generate enough wastewater for a Continuous Flow Wastewater Treatment System.
The Met-Chem Control Panel will automated the entire process. This includes turning the mixer on and off in timed intervals, monitoring the pH, adding chemistry, and notifying the operator when the batch is complete and they can begin to run the filter press. The controls can also be run in hand mode for manual treatment.
Met-Chem will work with your chemical supplier to ensure the proper treatment steps are taken to hit the proper pH target range. This also includes adjusting the pH to drop out solids from the solution and adding a polymer or flocculent to help settle those solids. Please note every system is unique and we will ensure our design fits your specific treatment needs.
Met-Chem pH Treatment Systems are customized for your application. Some features and options for your system may include:

Met-Chem can offer start-up and installation as an additional option. We can provide full support as you get your pH Adjust and Neutralization System up and running. We have installation technicians and technical representatives that we can send to your facility to make sure the system is running as it should.
All units and systems are complete with manuals and telephone support. However, if you need someone to come to your facility, we will be happy to quote you on that as well.
