Where KELIER
Technology Applies

Physics-driven, chemical-free wastewater treatment for three core energy industries. Each solution combines KELIER's proprietary separation technologies into an optimised treatment train.

Oilfield Produced Water

Onshore & offshore reinjection

Chemical-free treatment of oilfield produced water for reinjection and surface discharge. CDFU removes emulsified oil in 1–5 minutes — no coagulants, no oily sludge.

>90%Oil removal (CDFU)

<5 mg/LEffluent oil content

0Chemical additives

Refinery Wastewater

Desalting, sour water & tank washings

End-to-end treatment of refinery oily effluents — desalter blowdown, coker sour water, and crude tank washings. CDFU and CDOF handle oil and COD simultaneously without chemicals.

Power Plant Wastewater

Heavy/light fuel oil & coal washing

Physics-driven separation of fuel oil emulsions and coal-washing effluents from thermal power stations. CDFU and KHC deliver stable effluent quality across variable load and fuel type.

>95%Oil removal (KHC)
