Chemical Dosing Skids for an Industrial Wastewater Plant

Home > Projects > Chemical Dosing Skids for an Industrial Wastewater Plant

Three automatic dosing skids (PAC, PAM, pH) supplied for an industrial wastewater plant.

Project Background

The plant needed reliable, PLC-controlled dosing of coagulant, flocculant and pH chemicals instead of manual batching.

Our Solution

Skid-mounted preparation tanks with agitators and metering pumps, wired to the plant PLC for flow-paced dosing.

Process Train

  1. 1Chemical preparation tanks
  2. 2Metering pumps
  3. 3Dosing points (coagulation, pH, disinfection)
