How a Compact STP Works (3 Step Overview)
✔
Primary Treatment – Solids Removal. Inlet screening and grit separation.Settling tank removes ~30 % suspended solids.
Secondary Treatment – Biological Digestion .Aerobic microbes break down dissolved organics.BOD & COD drop to permissible limits.
✔
✔
Tertiary Treatment – Polishing & Disinfection .Nitrification–denitrification, phosphorus precipitation.UV irradiation delivers odor free, pathogen free water fit for reuse.
