Oil, grease and fine suspended solids stop biology dead. We supply DAF units, plate separators and skimmers that take them out first, sized from your oil and TSS load, with the chemistry to break emulsions when free oil is not the whole story.
Free oil floats and can be skimmed; emulsified oil and fine, light solids do not settle and must be floated with coagulant and micro-bubbles. Food, dairy, edible-oil, meat, refinery, automotive (coolant, paint-shop), metal-working and chemical plants all produce these streams. Discharge norms (oil & grease ≤ 10 mg/L) and the health of the downstream biological plant both demand removal at the front end.
Free oil and coarse droplets, plate separator, no chemicals. Emulsified oil, FOG and fine solids, DAF with coagulant. Many plants need a plate separator first and DAF second.
30–60 % on food and dairy effluents where COD is largely FOG and solids; less on dissolved streams. It is a pre-treatment, not a complete ETP.
DAF float (5–10 % solids) goes to sludge holding and dewatering; oily float from separators to a slop tank for recovery or authorised disposal.
Send flow, oil & grease, TSS and COD: we reply with the right separator/DAF size and expected removal.
