PH Adjustment

Walchem pH Equipment

PH Adjustment System

Pictured is a Walchem EK series (water proof) metering pump and pH controller integrated into a pH adjustment system.  This system adjusts the pH of tanker truck cleaning wastewater using sulfuric acid.  The typical pH of the wastewater can be as high as 13 as a result of the caustic cleaning process.  This wastewater is trucked to a sister facility for treatment, but must undergo pH adjustment prior to transport to insure that it is not characteristically hazardous.

Walchem pH controllers and EK series metering pumps are available from Blue Sphere Water Technology as both stand alone equipment items or part of a larger engineered system.
