When Water Cut Passes 90%: Rethinking Surface Separation for Mature Onshore Oilfields

2026-09-18

Composite water cut above 90% has changed what oilfield surface facilities must do. Gravity settling and heavy chemical dosing are losing ground to compact pure-physical separation that cuts retention time, footprint and O&M exposure at the same time.

From Emulsified Oil to Marine Discharge Limits: Combining CDFU, KHC, CDOF and KFM by Objective

2026-09-18

Water quality decides the treatment sequence. This article maps five common objectives - heavy emulsification, extreme oil concentration, composite oilfield pollution, terminal polishing and COD-driven limits - onto the SINOKLE module combinations that an

Cutting Chemicals Out of Oilfield Condensate Water: What a CDFU and SFM Physical Train Changes

2026-09-18

Chemical dosing has been the default for oilfield condensate-water deoiling for decades. A pure-physical CDFU plus SFM route removes the dosing step entirely, cutting sludge, O&M workload and energy use while keeping separation stable under fluctuating fe

Why No Single Unit Fits Every Oily Stream: Route Selection with CDFU, CDOF, KFM and KHC

2026-09-18

Industrial streams differ too much for one standard treatment train. This guide walks through six real water types - high-oil refinery effluent, high-oil acidic water, oil-depot shock loads, composite oilfield water, landfill leachate and terminal polishi

SINOKLE Wins Bid for Oily‑Wastewater Treatment Project of Oil‑Tank Farm at Dar Port, Tanzania

2026-09-18

 SINOKLE has recently secured the bid for the oily‑wastewater treatment project of the oil‑tank farm at Dar es Salaam Port, Tanzania, undertaken by China Railway Major Bridge Engineering Group. T

Pesticide Wastewater: Matching Five Very Different Streams to the Processes That Can Handle Them

2026-09-17

Pesticide wastewater spans benzene, organophosphorus, phenolic and mercuric streams. This compares biological, micro-electrolysis, photocatalytic, ultrasonic and ozonation routes against the concentrations each can actually treat.

Membrane Bioreactor Configurations Compared: From EMBR to Submerged Hollow Fibre, What Changes

2026-09-17

A walk through MBR variants: aerated, extractive, split and submerged configurations, plate versus hollow fibre modules, real plant capacities, and the energy and fouling costs behind the effluent quality.

Coal Gasification Wastewater Under ZLD: Placing Catalytic Ozonation Where It Actually Pays

2026-09-17

Coal gasification wastewater breaks conventional advanced oxidation. This explains where SINOKLE's CDOF catalytic ozonation and swirl air flotation unit fits in a zero-liquid-discharge train, and why ozone solubility matters.

Electrodialysis and EDR: Where Ion-Exchange Membranes Still Beat Reverse Osmosis on Cost

2026-09-17

Electrodialysis moves ions through selective membranes under a DC field. This covers membrane selectivity, EDR operation, typical voltage and energy figures, and where the process still makes economic sense.

CASS Process Design: One Basin, Cycled Phases, and No Secondary Clarifier to Operate

2026-09-17

The CASS process runs aeration, sedimentation and decanting in one tank. Here is how the biological selector zone, cycle timing and aeration hardware choices shape effluent quality and land use.
