The wastewater treatment process varies slightly from industry to industry and can be broadly divided into physical sedimentation, chemical and biological methods. Regardless of that method, all of them will be in contact with chemical solutions, and the corrosiveness of the solutions is greater or lesser according to different processes, such as neutralization reaction and redox reaction, which will use strong acid or alkali and are more corrosive, while extraction and other solutions are generally not very corrosive.
QEEHUA pump suggests choosing chemical pumps of suitable materials according to corrosive chemicals, and corrosion-resistant materials are generally available in FRPP and PVDF or CFRETFE.
Wastewater treatment process flow in focus.
Neutralization: neutralization of acid and alkali to achieve neutral pH.
Oxidation reduction: Oxidizing (or reducing) agent is added to oxidize (or reduce) the substances in the wastewater to harmless substances.
Electrolysis: Electrode plate is inserted into the wastewater, and when it is energized, the charged ions in the wastewater become neutral atoms.
Extraction: The solvent is separated out by using the relative density difference between the solvent and water.
