Carriers That Never Stop Moving: An MBBR Field Guide Built on Mill Effluent

2026-09-15

What makes a moving bed biofilm reactor run without backwashing, how carrier surface area and aeration drive the process, and what pilot work on newsprint, pulping and bamboo mill effluent achieved.

Ozone Advanced Treatment on a 15-Minute Clock: Reading the CDOF Upgrade Claim by Claim

2026-09-15

An item-by-item audit of the CDOF ozone catalytic oxidation advanced-treatment upgrade: patented catalysis, ozone dosing ratio, retention time, skid footprint, sealed operation and shock-load behaviour, plus the limits.

Five Checks Before You Retrofit a WWTP Flotation Unit: Two-Stage CDFU Line by Line

2026-09-15

A claim-by-claim reading of the two-stage CDFU flotation upgrade for wastewater treatment plants: physical demulsification, compressed PAC dosing, sealed operation, retention time and shock-load behaviour, with a before/after list.

No Pressure Vessel, No Compressor: What Cavitation Air Flotation Changes on Site

2026-09-15

How cavitation air flotation generates microbubbles without a saturator, what a Q=200 m3/h CAF unit draws in power against DAF, and where the design fits in papermaking, dyeing and food effluent.

Matching Units to the Pollutant: How SINOKLE Assembles Treatment Trains for Hard Wastewater

2026-09-15

A plant owner's view of difficult industrial wastewater: why single units fail, how CDFU cyclonic flotation, CDOF ozone oxidation and KFM media filtration get combined, and what the Congo-Brazzaville oilfield and refinery projects delivered.

Walnut Shell Media Still Beats Sand in Oily Water: Where the Filter Earns Its Keep

2026-09-14

Conventional sand filters harden and blind when they meet oily water. A walnut-shell filter with naturally oleophilic media, deep-bed grading and enhanced air-water backwash runs longer cycles at lower water use. Here is what changes in practice.

Desalter Draw-Off Water: Choosing Between One-Stage and Two-Stage Physical De-oiling

2026-09-14

Desalter draw-off water carries high oil, resin, asphaltene and severe emulsification. A purely physical train built on a coalescing de-oiler plus CDFU cyclonic dissolved-air flotation handles it without chemicals. Here is how the two configurations diffe

Chloride at 8000 mg/L Is What Kills Catalysts: Inside the A40 Precious-Metal Grade

2026-09-14

High-chloride biochemical tail water deactivates ordinary precious-metal media fast. KLE-HEC-200-A40 carries a double cerium protective layer and higher metal loading than A20. Three projects - leachate, pesticide and API - show the operating results.

Desalter Cut Water Still Fails COD After De-oiling? The Carbon-Based Catalyst Option

2026-09-14

Physical de-oiling gets desalter cut water to low oil but leaves dissolved organics that fail COD consent. KHC-F1001, a carbon-based ozone catalyst on a 1400 m2/g activated carbon carrier, is designed for that residue, with results from three industries.

Landfill Leachate at 20000 mg/L COD: What a Silica-Alumina Catalyst Does Differently

2026-09-14

High salinity and extreme pH destroy most ozone media within months. KHC-F2001 uses a silica-alumina composite carrier for that duty, and three projects - landfill leachate, antibiotic synthesis and refinery polishing - show the operating envelope.
