Does a higher dosage of water treatment chemicals result in better treatment outcomes?

 No, the dosage must be controlled within the “optimal range”; overdose can actually cause problems:

Excessive Algicide： For instance, over-dosing PAM causes flocs in water to carry excessive charge and disperse, making them difficult to settle and increasing effluent turbidity; PAC overdose lowers water pH and may even leave residual aluminum ions, compromising water safety;

Excessive scale inhibitor: Not only increases costs but may also form “chemical scale” with ions in the water (e.g., organic phosphonates excessively react with Fe³⁺ to form precipitates), potentially clogging pipelines;

Excessive biocide: For instance, excessive sodium hypochlorite corrodes metal equipment and may disrupt subsequent treatment processes (e.g., impairing microbial activity in biological treatment tanks);

Excessive corrosion inhibitor dosage: Certain inhibitors (e.g., chromate) become toxic at high concentrations and may cause chemical wastage.

Therefore, the “minimum effective dosage” must be determined through pilot testing and on-site adjustments, with dynamic recalibration based on water quality fluctuations.
