Customized pH control systems for all wastewater and pH neutralization applications found in industry. Common applications and features include:
Typical pH Control Curves used with all of our pH adjustment systems. For each pH control stage within a system the tuning parameters for the acid and metering pumps (and bulk assist pumps if used) are independently controlled with non-linear tuning algorithm that can be programmed to any curve, such as a titration curve.
pH response is not linear and cannot be controlled as such. Most pH "controllers" on the market are not truly pH controllers because they use simple on / off control or linear control provided by a PID algorithm which is far too simple to account for the ever changing control gain encountered with the logarithmic reaction of pH to control input. A true pH controller MUST have the ability to control to a logarithmic and non-linear response such as the typical pH titration curve shown here.
