Ship Oily Water Treatment: Inside the MARPOL Compliance Chain

2026-10-12

Bilge water and tank washing water put every ship under MARPOL and GB 3552-2018 limits. This walkthrough covers the screening, coalescence and polishing chain, and the four mainstream separation routes, then shows how SINOKLE pairs a coalescing oil remove

Fracturing Flowback Fluid in Xinjiang: Zero-Chemical Treatment at 360 m3/d

2026-10-12

Fracturing flowback fluid combines complex composition, high viscosity and severe emulsification, which makes reagent-heavy treatment routes expensive twice over. The SINOKLE chain pairs CDOF ozone catalytic oxidation for deep gel breaking and viscosity r

Dual Carbon Pressure Meets Oily Wastewater: Energy, Chemicals and Sludge in One Frame

2026-10-12

Industrial wastewater treatment consumes energy, chemicals and produces sludge, and the three costs are usually managed separately. CDFU swirl dissolved air flotation compresses hydraulic retention time from 15-40 minutes to 1-5 minutes by coupling a swir

C16+ in Refinery Heavy Feedstock: What It Means for Electric Desalting Wastewater

2026-10-12

C16+ components, hydrocarbons with 16 or more carbon atoms, define the heaviness of heavy crude at 70%-90%, waste oil at 65%-85% and residue at 85%-98%. They reach electric desalting wastewater through oil-phase entrainment and trace dissolution at total

Inside the Dissolved Gas System: What EDUR Multiphase Pump Technology Changes in a DAF Train

2026-10-12

A dissolved air flotation train is only as good as the bubbles feeding it. The SINOKLE EDUR high-efficiency dissolved gas system pairs German-made EDUR multiphase pump components with patented swirl centrifugation and ultra-fine bubble generation, reachin

Ozone Disinfection in Water and Air: Real Strengths, Real Limits, and the Bromate Question

2026-10-12

Ozone kills by disrupting organelles and DNA/RNA, penetrating membranes and diffusing through an entire treatment volume, which is why it leaves no dead corners and no residue. The trade-offs are equally concrete: higher capital and running cost than chlo

Flotation Selection Guide: From DAF Fundamentals to CDFU Operating Data

2026-10-12

Flotation uses fine bubbles as carriers that lift oil droplets and solids to the surface as scum. Four bubble-generation routes suit different waters, and the choice is dictated by water quality rather than preference. Where conventional CFU designs stall

Wellhead Produced Fluid Treatment: A Modular Route from Three-Phase Separation to Reinjection

2026-10-12

Wellhead produced fluid is a multiphase mixture of crude oil, water, natural gas and suspended solids whose oil content swings widely and whose emulsion is stable. The classic gravity settling, coagulation and filtration train answers with long residence

Choosing Oil-Water Separation Equipment: Why Footprint and Turndown Beat Headline Efficiency

2026-10-12

Specifications for oily wastewater have tightened on concentration, droplet size and variability at the same time. Four failures show up in long-term operation: settling that misses fine droplets, footprints that need civil works, flow regimes too fragile

Refinery Wastewater: Cutting COD and Protecting Membranes with CDOF Ozone Catalysis

2026-10-12

Refinery wastewater fails operators in two familiar ways: COD that will not stay compliant, and membranes that foul long before the design case predicted. The conventional answer, biological treatment plus Fenton plus membrane filtration, buys performance
