20/3/2019, · Low and high ,pH, set points too close together. Having ,pH, set points too close causes the system to “fight” itself. This scenario occurs when ,acid, is added, driving the ,pH, below the lower set point. This causes the system to add caustic and the ,pH, then rises above the high set point, causing an ,acid, addition. The cycle then repeats.

Defining pH Neutralization Systems | Pumps & Systems

The preferred method for pH neutralization of waste streams is by the automatic addition of acid or caustic. The ideal setup is a batch neutralization module. A basic batch system includes a treatment tank with a mechanical agitator (mixer), an in-tank pH sensor, an in-tank level control, metering pumps for acid and caustic injection, an automated drain valve or pump for the effluent, and a control panel.

Most ,wastewater pH, neutralization systems are well suited for submersion sensors from the top of the tank. Use couplers and plastic pipe attached to the top of the ,pH, sensor to keep the cable out of contact with the solution and chemicals. 1. Support the sensor and pipe so it does not move around in the tank and impact the tank wall or mixer. 2.

The acidity or alkalinity of wastewater affects both industrial wastewater treatment and the environment. Low pH is acidic, high pH is alkaline, and a pH of 7 is neutral. The universal standard pH for wastewater discharge compliance ranges between 6 and 9; although some POTW’s allow higher or lower pH ranges.

A pH adjuster is a chemical used to alter the pH or Potential Hydrogen level. pH (Potential Hydrogen) is the measurement of the activity of the hydrogen ion or how basic or acidic something is. By adding a pH reagent such as an acid you can drive pH downward. By using a caustic or other alkaline substance you can drive pH upward.
