Activated Carbon in Wastewater Polishing: Capacity, Isotherms and the Choices That Decide Operating Cost

2026-10-30

Activated carbon adsorption remains the default polishing step whenever dissolved organics, colour and odour survive upstream treatment. This article explains how powdered and granular grades differ, how the Freundlich isotherm guides carbon selection, wh

Why Polyacrylamide Behaves Differently in Every Plant: Monomer Routes, Viscosity and Dosing Practice

2026-10-30

Polyacrylamide is the most widely used organic polymeric flocculant in water treatment, yet its performance varies sharply between plants. This guide walks through the three generations of acrylamide monomer technology, polymerisation and drying practice,

Coking Sour Water: A Four-Stage Physical Train Instead of Chemical Demulsification

2026-10-29

Coking sour water combines a low pH, a severe emulsion, heavy solids and a long list of heterocyclic organics, which is why neutralisation and activated sludge both disappoint. This analysis walks through the four difficulties, explains why chemical route

Why Heterogeneous Ozone Catalysis Replaced Homogeneous Fenton in Plant Design

2026-10-29

Two oxidation potentials frame the whole argument: hydroxyl radicals at 2.8 V and ozone at 2.07 V. This piece follows the shift from soluble metal catalysts to a patented solid system, explains what happens at the Lewis acid centres of a metal oxide surfa

Two Ozone Catalysts, Two Jobs: KHC-PC1001 Versus KHC-F2001 in Practice

2026-10-29

A carbon carrier and a silica-alumina carrier solve different problems, and pairing them badly is a common reason ozone systems miss their numbers. This comparison sets the two SINOKLE catalyst grades side by side on surface area, strength and salinity to

Reading KHC-F1001 by Its Numbers: Surface Area, Ozone Split and Strength

2026-10-29

Catalyst selection is mostly the skill of reading a parameter sheet as an engineering argument. This breakdown takes the carbon-based KHC-F1001 apart item by item - iodine number, ozone decomposition rate, chemical oxygen demand and colour removal, streng

Sour Water De-oiling with CDFU and KHC: A Physical Route Without Chemicals

2026-10-29

Stripper trays and reboilers foul with aluminium compounds that arrive with the coke fines and oily sludge in sour water, and conventional flotation plus membrane de-oiling cannot hold the line. This analysis explains the equilibrium the stripper exploits

Ozone Catalyst Manufacturing: Pore Forming, Sintering and the Strength Trade-off

2026-10-29

A catalyst that wins on surface area often loses on strength, and a catalyst that survives handling often loses on activity. This account of the SINOKLE ozone catalyst series covers carrier chemistry, the pore-forming routes that resolve the strength conf

HCC Cyclonic Coalescing: Cutting Emulsified Oil Down to 0.1 μm Droplets

2026-10-29

Cyclones are simple, compact and cheap to run, yet conventional units lose fine droplets and force plants into cartridge filters that clog. This analysis follows the flow path through the HCC high-efficiency cyclonic coalescing unit, explains where coales

Homogeneous or Heterogeneous Ozone Catalysis: A Practical Selection Framework

2026-10-29

Both catalytic routes activate ozone and both raise chemical oxygen demand removal, yet they behave very differently once the catalyst has to leave the reactor. This comparison sets out the reaction mechanisms, the separation penalty attached to soluble m
