Seawater Desalination Routes Compared: Thermal, Membrane and the Freeze Option

2026-11-09

Distillation, membranes and freezing all remove salt from seawater, but they fail for different reasons and suit different project sizes. This comparison sets out where multi-stage flash still wins, what limits reverse osmosis in practice, how electrodial

Diatomite in Water Treatment: Pore Structure, Surface Chemistry and Where It Earns Its Place

2026-11-09

Diatomite is sold as a filter aid, a filler and a catalyst support, but the grades behave very differently. This piece reads the physical data sheet line by line, explains why refined material outperforms the raw product, compares four modification routes

Refinery Circulating Water De-Oiled at 17,000 m3/d: Coalescing Oil Removal at Scale

2026-11-09

Refinery circulating water picks up oil from cooling-loop leaks and process media, and its emulsified, fluctuating character makes stable de-oiling difficult. This article reviews how the coalescing oil remover works - fibre capture, bidirectional flow, C

Inside the KHC Coalescing Separator: 0.1 um Droplets at a 0.05 MPa Pressure Budget

2026-11-09

The KHC series coalescing oil-water separator from SINOKLE Technologies demulsifies hard-to-break emulsions purely physically: a single unit handles up to 50 m3/h at a pressure drop of no more than 0.05 MPa, removing emulsified droplets of 0.1 um and larg

Desalting Wastewater at 100,000 mg/L of Oil: A Purely Physical Route That Holds Up

2026-11-09

Electric desalting washes salts and water out of crude oil and leaves behind a wastewater that can carry an oil phase above 10% and salinity of 2,000-5,000 mg/L as chlorides. Heavier crude slates keep widening that spread. This article reviews the purely

Ternary Precursor Liquor at pH 2 to 3: Oil Below 2 ppm Without Activated Carbon

2026-11-09

Ternary precursor liquor for battery materials is saturated with sulfates at pH 2 to 3 and carries oil and TOC that damage cathode material quality. The conventional answer - coconut-shell activated carbon plus special resins - is costly, saturates within

CDOF Catalytic Ozonation: 99.98% Ozone Utilisation and 15-Minute Reaction Windows

2026-11-09

Catalytic ozonation only pays off when ozone is used efficiently. CDOF, developed by SINOKLE, couples multi-path catalytic ozonation with cyclonic separation and dissolved-air flotation, cutting ozone dosage to 1/5-1/2 of conventional lines while reaching

From 20,000 ppm Inlet Oil to Discharge Quality: CDFU Units Across Four Deployments

2026-11-09

The CDFU cyclonic dissolved gas flotation unit from SINOKLE combines centrifugal separation, dissolved gas flotation and ultra-fine bubble generation in one compact shell, removing oil down to particles below 2 um with only 1-5 minutes of retention. This

Emulsified Oil Down to 10 ppm: The Zero-Chemical Route Built on CDFU and KHC

2026-11-09

Highly emulsified oily wastewater is the classic case where chemical demulsifiers cost more than they recover. This article walks through a purely physical alternative built around the CDFU cyclonic dissolved gas flotation system and the KHC coalescing se

Sour Water Carrying 3,000 mg/L of Oil: Where Gravity Settling Fails and CDFU Kicks In

2026-11-09

Coking sour water can carry 500-3,000 mg/L of oil together with coke fines finer than 20 um, clogging strippers and overloading downstream units. Gravity settling demands 50-70 hours of retention, while cyclonic and membrane routes struggle with 0.1-20 um
