UASB Reactor

UASB (Upflow Anaerobic Sludge Blanket): An “Oxygen-Free” Bed That Turns High-Strength Organic Wastewater into Biogas — Industrial Emission Reduction That Pays Back in Energy

Nationwide (food, brewing, starch, pharma, MSG, paper)

Pilot to full-scale (10s–10,000s m³/d)

UASB (Upflow Anaerobic Sludge Blanket) is a second-generation high-efficiency anaerobic reactor that removes 70–90% COD at 4–15 kgCOD/(m³·d) while producing methane biogas. Covers mechanism, design parameters and real MSG/alcohol wastewater data.

MBBR Reactor

MBBR (Moving Bed Biofilm Reactor): Carriers Drift in the Water, Microbes Cluster on Them — Compact and Stable Industrial Wastewater Upgrading

Nationwide (pharma, coking, petrochem, paper, TCM)

Pilot to full-scale (10s–10,000s m³/d)

MBBR grows biofilm on suspended HDPE carriers like Kaldnes K1 — compact, shock-resistant, no sludge return. Covers filling fraction, surface loading and HRT with real industrial cases.

Aerated Biofilter

Biological Aerated Filter (BAF): Squeezing "Biofilm + Filtration" into One Tank — a Compact Powerhouse for Industrial Wastewater Advanced Treatment

Nationwide (dyeing, fine chem, pharma, food, municipal upgrade)

Pilot to full-scale (100s–10,000s m³/d)

The biological aerated filter (BAF) integrates biofilm oxidation and physical filtration in one reactor, cutting footprint and effluent turbidity without a secondary clarifier.

Activated Carbon Ads

Activated Carbon Adsorption (GAC/PAC): "Catching" the refractory organics that "slip through" in the biological effluent.

National Multi-Industry (Printing and Dyeing / Pharmaceutical / Coking / Chemica

Pilot-scale to full-scale engineering (from tens to tens of thousands of m³/d)

Activated carbon adsorption serves as the "safety net" unit for advanced treatment of industrial wastewater, capable of removing refractory COD, color, and micropollutants remaining after biological treatment. Based on public literature and engineering ca

Sulfur-based Autotro

Sulfur-based Autotrophic Denitrification (SAD): Nitrogen Removal Without Carbon — A "Zero-Carbon Source" Pathway for Advanced Nitrogen Removal from Low C/N Industrial Wastewater

Across multiple industries nationwide (groundwater remediation / municipal efflu

Pilot-scale to full-scale engineering (from tens to tens of thousands of m³/d)

Sulfur-based autotrophic denitrification (SAD) utilizes elemental sulfur, thiosulfate, or sulfide as electron donors and inorganic carbon as the carbon source, enabling the reduction of nitrate to nitrogen gas without the need for external organic carbon.
