From Hydrocyclone to CFU: How Offshore Platforms Strip Oil Out of Produced Water

2026-10-26

Offshore platforms treat oily produced water under tight space, weight and discharge limits, so every stage has to earn its footprint. This article walks through a typical three-stage train — inclined-plate separation, hydrocyclone and walnut shell filter

Reclaimed Water as a City's Second Water Source: Quality Rules, Costs and Real Projects

2026-10-26

Reclaimed water turns treated municipal sewage into a dependable non-potable supply for industry, irrigation and urban services. This guide explains where the term comes from, how risk-based quality standards such as fecal coliform limits, COD and TSS thr

Hydroxyl Radicals at 2.8 V: How a Heterogeneous Ozone Catalyst Beats Plain Ozonation

2026-10-26

Ozone has an oxidation potential of 2.07 V yet still fails on many refractory molecules, because the reaction is selective and much of the gas escapes before it reacts. This article explains how a heterogeneous ozone catalyst redirects the chemistry towar

Coking Sour Wastewater at 15% Oil: A Fully Physical Train of CDFU, Filtration and KHC

2026-10-26

Sour water from coking carries fine coke particles, tightly emulsified oil, sulphur, ammonia nitrogen and phenols, and sending it straight to the stripper blocks trays and degrades the liquid ammonia product. This article follows a four-stage physical tra

KHC-F2001 and CDOF: Pairing a Silica-Alumina Ozone Catalyst with an Integrated Flotation Unit

2026-10-26

Advanced ozone oxidation is limited less by ozone chemistry than by how much of the ozone actually reacts before it escapes. This article looks at the two components SINOKLE pairs to close that gap: the KHC-F2001 silica-alumina catalyst with its multistag

Emulsified Oil Explained: Composition, Stability, HLB and Why DAF Needs a Coagulant First

2026-10-26

Emulsified oil is a manufactured product as much as a pollutant: base oil, emulsifier, rust inhibitor and stabiliser blended in fixed proportions, then dispersed into droplets small enough to stay suspended for months. This article unpacks the formulation

Pharmaceutical Wastewater at 6000 mg/L COD: What a CDOF Train Delivered in Inner Mongolia

2026-10-26

Pharmaceutical effluent combines refractory organics, heavy metals and biotoxic compounds, and biological treatment alone removed only about 15% of the COD at one large Inner Mongolia site. This article examines how the CDOF process pairs homogeneous and

Thermal Power Plant Oily Water: Two-Stage CDFU plus KFM Filtration in a Sierra Leone Case

2026-10-26

Tank farm wash water, pump leakage, coal handling runoff and transformer drainage all reach the same drain, and the resulting oily wastewater is small in volume but heavy in consequence. This article compares settling tanks and chemical demulsification wi

CDOF in Four Settings: Where an Integrated Ozone Oxidation and Flotation Unit Pays Off

2026-10-26

Process selection for advanced wastewater treatment is really a decision about investment, footprint and the operating bill for the next decade. This article opens up the CDOF unit, a PCT-patented integration of catalytic ozonation, hydrodynamic cavitatio

Landfill Leachate Without Membrane Concentrate: How a CDFU and CDOF Train Removes the Brine Problem

2026-10-26

The standard leachate chain of pretreatment, MBR and nanofiltration or reverse osmosis produces clear water and a concentrate that costs more to dispose of than the treatment itself. This article examines why the membrane route plateaus on aged leachate,
