Offshore Gas Fields Have No Fresh Water to Dose With: Rethinking Highly Emulsified Produced Water

2026-09-14

Offshore produced water treatment fails on water balance long before it fails on chemistry. This analysis compares multi-stage dosing flocculation with a purely physical plus advanced oxidation train built on CDFU, SiC, KHC and CDOF units.

Zero Chemicals, Zero Hazardous Sludge: How Far Purely Physical Oil-Water Separation Can Really Go

2026-09-14

Emulsified oil is where most oily-wastewater plants fail. This review compares gravity, flotation, coalescing, centrifugal, filtration, membrane and chemical routes, and sets out where KHC, CDFU and KFM physical units take over from dosing.

Effluent Already Below 200 mg/L COD and Still Failing Consent: The Case for KLE-HEC-200-A20

2026-09-14

Low-concentration biochemical tail water is where conventional catalysts give up: organics are too dilute to drive good ozone transfer, and chloride passivates the active sites. KLE-HEC-200-A20 is built for exactly that band, and three projects show what

Municipal Tail-Water Polishing Without Extra Chemical Dosing: What a Dedicated Ozone Catalyst Changes

2026-09-14

Municipal secondary effluent is low in COD but full of humic substances, trace pharmaceuticals and odourants. A dedicated heterogeneous ozone catalyst targets that fraction, and this piece compares three plants where it replaced or preceded BAC and membra

High-COD Fine-Chemical Wastewater: Where KLEX-013 Sits Between Pre-Treatment and Biological Polishing

2026-09-14

Fine-chemical effluent with thousands of mg/L COD, heterocyclic toxins and swinging salinity breaks ordinary catalytic ozone. This review of KLEX-013 covers the carrier design, the specification limits that matter, and three plants running it continuously

Anthracite Over Garnet: Why Dual-Media Filters Outlast Single-Layer Beds on Oily Water

2026-09-11

Single-layer filters on oily water clog at the surface and backwash poorly. This article looks at how an anthracite-and-garnet graded bed with combined air-water backwash changes filtration cycles and effluent stability.

When Ozone Alone Stops Working: A Heterogeneous Catalyst Route for Refractory COD

2026-09-11

Refractory industrial wastewater resists conventional ozone oxidation because ozone utilisation is poor. This article sets out how a heterogeneous catalyst raises hydroxyl-radical yield and what the product series covers.

Chemical Wastewater: Picking Between Physical, Chemical, Physicochemical and Biological Routes

2026-09-11

Chemical wastewater is rarely treatable by a single unit. This overview sets out the four families of treatment method by action principle and shows which pollutant classes each one actually removes.

Refinery Overhead Sour Water: Breaking a Surfactant-Locked Emulsion in Minutes

2026-09-11

Crude slates are getting heavier and atmospheric/vacuum overhead sour water is increasingly emulsified. This article explains the interfacial chemistry behind that emulsion and how a SiC filter plus KHC coalescing remover answers it.

Offshore Skid Oily Water Units: Designed for Shock Loads, Not for the Design Point

2026-09-11

Offshore floating facilities produce emulsified cut-water under constant motion and feed swings. This article explains why stability across a wide load band, not rated-condition data, is the real acceptance criterion for a treatment skid.
