What Lets a SiC Ceramic Membrane Survive High-SS Oily Service Where Organic Membranes Quit Early

2026-10-28

A membrane filtration device is only as good as its material, structure and operating mode. This technical dissection of the SINOKLE ultra-fine SiC membrane filter explains why silicon carbide wins on hydrophilicity and chemical durability, how the honeyc

Why Emulsions Refuse to Separate: A Practical Guide to Demulsification Methods and Mechanisms

2026-10-28

Demulsification destroys the conditions that keep an emulsion stable, letting dispersed droplets flocculate, coalesce and split into clean oil and water layers. This guide explains the two-step breakdown mechanism and its reversibility limits, the main de

Commissioning Numbers That Matter: A KHC Coalescing Skid on High-Oil Sour Water

2026-10-27

Emulsified sour water threatens strippers and sulfur recovery while wasting recoverable light oil. This commissioning report follows a KHC coalescing oil-removal skid through three-point sampling: effluent oil between 15 mg/L and 35 mg/L, corrected values

From 1,300 mg/L to Surface-Water Class III: A CDOF Leachate Project Broken Down

2026-10-27

A landfill leachate project in Shiyan, Hubei shows what CDOF advanced catalytic ozonation can do: upstream MBR effluent with COD around 1,300 mg/L cut below 400 mg/L, then biologically polished to surface-water Class III. The article details the reactor d

Homogeneous Versus Heterogeneous Ozone Catalysis: What Changes When the Catalyst Is a Solid

2026-10-27

Catalysts turn ozone from a selective disinfectant into a broad-spectrum oxidation engine for refractory wastewater. This comparison of homogeneous and heterogeneous ozone catalytic routes covers transition metal ions, metal oxide catalysts, secondary-pol

Coking Wastewater Without Chemicals: How CDFU and KHC Tackle Coal Chemical Effluent

2026-10-27

Coking wastewater combines high salinity, high toxicity and poor biodegradability with some of the most stubborn emulsified oil in industry. This article explains the 0.1-0.35 m3 per ton of dry coal generation rate, the purely physical CDFU and KHC separa

Four Projects, One Filter Media: Field Evidence Behind SFM Super-Hydrophilic Filtration

2026-10-27

Filter media earn their reputation in the field, not the brochure. Four documented projects from 2017 to 2025 — Changqing Oilfield, PetroChina Huabei, the Republic of the Congo and a Sierra Leone power plant — show how SFM super-hydrophilic media, paired

Sour Water, Solved in Three Stages: CDFU, SiC Filtration and a KHC Coalescing Finish

2026-10-27

Sour water rich in emulsified oil and coke fines plugs strippers and defeats gravity settling, cyclones and membranes alike. This article breaks down why each conventional route fails, then walks through the SINOKLE combined process of CDFU, SiC filtratio

A Short History of Corrosion Inhibition: From Syrup and Vegetable Oil to Green Polyaspartic Acid

2026-10-27

Corrosion costs the world USD 1.8 trillion a year, and chemical inhibition is the main line of defence. This history runs from 1845 pickling additives and the first 1860 patent to HSAB theory, composite formulations and modern green inhibitors such as pol

Sodium Hypochlorite 101: Chemistry, Storage Rules and Why Bleach and Toilet Cleaner Never Mix

2026-10-27

Sodium hypochlorite bleaches, disinfects and treats water — and decomposes violently when stored hot. This primer covers its formation from sodium hydroxide and hypochlorous acid, hydrolysis behaviour, the acid reactions behind the bleach-plus-cleaner chl
