CDFU vs Conventional Dissolved Gas Flotation: Where the Real Gap Opens Up

2026-11-06

Both technologies float oil out of water with bubbles, yet the performance gap between CDFU and a conventional dissolved gas flotation cell is structural rather than incremental. This comparison works through bubble size distribution, vessel geometry, ret

Why Independent Refiners Keep Failing, and Where CDFU Fits in the Survival Plan

2026-11-06

Shandong Huifeng Petrochemical filed for bankruptcy in 2025 despite once ranking in China's top 500. This analysis separates the three pressures that broke it from the ones a plant can still control, and shows what a CDFU based physical treatment train ch

Advanced Ozone Oxidation Beyond O3/H2O2: What the CDOF Route Changes

2026-11-05

Ozone alone is selective, slow against refractory organics and wasteful of the oxidant it consumes. This article reviews the advanced oxidation combinations in common use, then examines how the SINOKLE CDOF process pairs a heterogeneous catalyst with cycl

Isothiazolinone in Cooling and Process Water: Dose Windows and Handling

2026-11-05

Isothiazolinone is a non-oxidising broad-spectrum biocide built from CIT and MIT, and it is dosed in milligrams per liter rather than by feel. This article covers how it kills, the dose windows used for slime stripping and routine bactericide duty, its co

Sodium Sulfate Wastewater and CDOF: Reading a 1067 mg/L COD Trial Closely

2026-11-05

Sodium sulfate wastewater from chemical, pharmaceutical, dye and pesticide plants carries dissolved salts and refractory organics that ordinary biological treatment cannot close. This article examines the CDOF ozone catalytic oxidation process, its micro

Inside the KHC Coalescing Separator: Fibre Media, Vortex Flow, 0.1 um Cut

2026-11-05

High-concentration oily wastewater needs a separator that grows fine droplets instead of waiting for them to rise. This article opens up the KHC coalescing oil-water separator from SINOKLE: the fibre media that capture and release droplets, the axial cycl

Sour Water From Delayed Coking: Three Mechanisms, Three Stages, One Train

2026-11-05

Coking sour water arrives with coke fines, emulsified oil and a composition that will not hold still, and each of those problems defeats a different piece of equipment. This article follows a three-stage arrangement in which fine filtration, the KHC coale

CDOF in Industrial Service: Catalytic Ozone, Flotation and the Cost Case

2026-11-05

Conventional wastewater treatment struggles with efficiency, cost and secondary pollution at the same time. This article examines the SINOKLE CDOF process, which combines catalytic ozone oxidation, cyclonic separation and dissolved gas flotation in one ve

Heavy-Oil Tank Farm Oily Water at Power Plants: Why CDFU Plus KFM Filters Holds

2026-11-05

Heavy-oil tank farm drainage at a thermal power plant can carry petroleum substances up to 1,000 mg/L along with solids and a stubborn emulsion. This article explains why oil separation tanks, flotation and chemical flocculation all fall short on that fee

Decanter Design in SBR Plants: Weir Travel, Floats and the Power-Free Option

2026-11-05

The decanter decides whether a sequencing batch reactor can draw off clear water without dragging sludge or scum with it. This article covers the weir, pipework and slewing support that make up the assembly, the PLC-driven cycle that governs its travel, t
