Black Liquor, White Water and the Reuse Ceiling in a Paper Mill

2026-09-21

A paper mill has two very different wastewaters and one reuse ceiling. This article separates pulping black liquor from machine white water, looks at magnetic separation pilot data, and shows why AFF filtration followed by MBFB is the combination that act

Breaking the B/C Barrier: How CDOF Catalytic Ozonation Re-Opens Biodegradability

2026-09-21

Refractory organic wastewater poisons the biology it is supposed to feed. This article explains how CDOF catalytic ozonation generates hydroxyl radicals at 2.80V, opens ring structures, lifts the B/C ratio from 0.1~0.2 toward 0.4 and above, and where it p

Reading a Water Body by Its Oxygen: From Winkler Titration to BOD5 and COD

2026-09-21

Dissolved oxygen is the single number that tells you most about a receiving water. This guide covers what controls it, how the Winkler titration is run and where it goes wrong, how membrane probes differ, and how BOD5, BOD20 and COD each describe a differ

Where the Pollution in an Electroplating Line Actually Comes From: A Stream-by-Stream Breakdown

2026-09-21

Electroplating plants rarely fail on one bad stream; they fail because eight or nine chemically different drains are mixed into one header. This piece traces each stream back to its process step, then walks through flotation, ion exchange, electrolysis, e

Holding Power-Plant Draw-Off Water Below 10 mg/L With Two-Stage CDFU and KFM Media Filtration

2026-09-20

Heavy-fuel-oil tank draw-off water is black, emulsified and loaded with sediment, yet must discharge below 10 mg/L oil. This article explains how two-stage SINOKLE CDFU physical demulsification plus KFM active media filtration divide the duty and hold tha

Emulsified Oil in Battery-Material Effluent: What Ozone Catalytic Oxidation Demulsification Achieves

2026-09-20

Emulsified oil wrapped in a surfactant film defeats conventional coalescence. This article breaks down how SINOKLE CDOF breaks that film with ozone catalytic oxidation, captures droplets with sub-10 um nanobubbles, and reports pilot data from battery-mate

Tank-Bottom Water Without Chemicals: Coalescing Separation Paired With CDFU Cyclonic Flotation

2026-09-20

Chemical demulsification of tank-farm draw-off water creates oily hazardous sludge and poor recovered oil. This article explains how a high-efficiency coalescing oil remover plus SINOKLE CDFU cyclonic dissolved air flotation holds effluent at 35 mg/L with

The Concentrate Trap Behind MBR and RO Leachate Trains, and the Membrane-Free Way Out

2026-09-20

Dual-membrane leachate trains produce clear water and a concentrate stream above 5000 mg/L COD that nobody can dispose of. This article examines that trap and how SINOKLE's CDOF route mineralises pollutants instead, with no membrane and no concentrate.

One Unit Is Rarely Enough: Matching CDFU, CDOF and KFM Trains to Mixed Industrial Effluent

2026-09-20

High oil, high suspended solids, high COD and severe emulsification rarely yield to a single unit. This article sets out how SINOKLE combines the CDFU, CDOF, KFM and coalescing deoiler into trains for overseas oilfields, heavy-oil power stations and minin

What Sets Slaughterhouse Wastewater Apart: Blood, Grease and an Ammonia Load Near 120 mg/L

2026-09-20

Slaughterhouse wastewater carries blood, grease, hair and feces, and putrefies quickly. This overview covers its sources, its roughly 120 mg/L ammonia-nitrogen load, the HJ 2004-2010 and GB 13457-92 standards that apply, and the design principles that kee
