Dosing Ozone Is Not Oxidizing: What CDOF Changes About Advanced Oxidation Design

2026-09-10

Ozone contactors waste most of the gas they are fed. CDOF couples catalytic oxidation, cyclonic mass transfer and flotation in one enclosed vessel, cutting reaction time from 60-90 min to 10-15 min.

From 20000 ppm to 150 ppm: How Cyclonic Flotation Handles Oil That Refuses to Separate

2026-09-10

Oily wastewater carries floating, dispersed and emulsified oil at once. CDFU stacks cyclonic separation, dissolved-air flotation, micro-nano bubbles and coalescence; two project cases show the results.

When Influent Oil Swings from 500 mg/L to 5000 mg/L: A Field Case for Cyclonic Flotation

2026-09-10

Deeply emulsified oily wastewater defeats DAF and IGF. This analysis explains the microbubble and centrifugal coupling inside CDFU, its 15-60 second retention, chemical savings and enclosed VOC control.

Landfill Leachate Without the Chemical Mountain: A Closed-Loop CDFU + CDOF + MBR Train

2026-09-10

Landfill leachate defeats conventional flow sheets. A closed-loop train combining CDFU, multi-stage CDOF ozone oxidation, high-efficiency denitrification and MBR cuts footprint and chemical use while holding effluent stable.

Oil Depot Draw-Off Water: How a Two-Stage Physical Train Recovers Gasoline and Reuse Water

2026-09-10

Light-oil depot draw-off water must meet two goals at once: reusable effluent and saleable recovered gasoline. This breakdown explains how CDFU rough flotation plus KHC coalescing deoiling achieves both without chemicals.

Granular Microfiltration: Where It Sits Between Coarse Filtration and Ultrafiltration

2026-09-09

Granular microfiltration uses nano-composite particles as the medium rather than a membrane sheet. This article covers the sieving, cake-layer, deep-bed and adsorption mechanisms, the 0.1-10 um separation range, and where the technology earns a place in a

Delayed Coking Sour Water: A Chemical-Free Route to Oil and Coke Fines Removal

2026-09-09

Oil and coke fines in delayed coking sour water coke up the downstream stripper. This article sets out a chemical-free pretreatment built on cyclonic dissolved air flotation plus coalescence oil removal, with filtration for fines, and the industrial resul

SiC Membranes Under Dirty Water: Honeycomb Cores, Cross-Flow Operation and the Limits of Organic Membranes

2026-09-09

Material, structure and operating mode set the performance ceiling of any membrane plant. This article examines why hydrophilic SiC, a honeycomb membrane core and cross-flow filtration together extend what a membrane can survive in oily and high-suspended

CDOF Explained: One Skid for Multi-Catalytic Ozone Oxidation and Cyclonic Dissolved-Air Flotation

2026-09-09

SINOKLE's CDOF folds ozone multi-catalytic oxidation, hydrodynamic cavitation and cyclonic dissolved-air flotation into a single enclosed unit. Retention under 15 minutes, ozone utilisation above 99.98%, and a fraction of the sludge of Fenton plus sedimen

CDFU in Numbers: Bubble Size, Retention Time and Chemical-Free Oil Removal Against Mainstream CFU Units

2026-09-09

A parameter-level look at SINOKLE's CDFU compact cyclonic dissolved gas flotation unit: 5-30 um bubbles, sub-5-minute retention, free-oil removal at or above 99%, no chemicals, and how it compares with mainstream CFU suppliers on bubble size and control p
