Equipment That Meets Every Stage of the Line

Every unit is engineered to your flow rate, influent characteristics and discharge standard. Full details below for every product.

Solutions

From Single Unit to Turn-Key Line

We work as an engineering partner: wastewater analysis, process design, equipment supply, installation guidance and commissioning support.

How We Work

Four Steps to a Compliant Discharge

Wastewater Analysis

Share your COD/BOD, SS, pH and flow data — or send samples. We size the line to your actual load, not a guess.

Process & 3D Design

Process flow diagram, equipment layout and 3D models for your review before fabrication starts.

Fabrication & QC

Factory test, material certificates and third-party inspection (SGS / Intertek) on request.

Installation & Support

Remote or on-site commissioning guidance, operator training and spare parts supply.

Engineer inspecting water treatment equipment on site

On-Site Service

Commissioning, troubleshooting and operator training are part of our delivery promise — not an extra.

Treatment Technologies for the Full Process Line

From high-strength organic loads to suspended solids and sludge, our technologies cover every stage — designed around your raw water quality and discharge target.

Water treatment engineering
Water treatment engineering capabilities

Two-Phase Catalytic Oxidation

Based on the Fenton reaction, integrating electrochemical coagulation, catalytic oxidation and flocculation-sedimentation. Hydroxyl radicals (·OH, +2.83 V, second only to fluorine) are non-selective to organics, breaking refractory macromolecules into small molecules and mineralizing them to H₂O and CO₂.

In-Situ Plant Expansion & Emergency Treatment

For capacity expansion and crashed-system recovery at existing plants: high-efficiency biofilm carriers (polyurethane soft media, cross-flow media, suspended porous ring media) and multi-stage A/O step-feed processes, combined with engineered bacteria (COD degraders, low-temperature nitrifiers) — dominant flora within 5 days and stable effluent within a week.

High-Strength Organic Wastewater Treatment

CSTR hydrolytic acidification improves biodegradability and organic loading; enhanced EGSB reactors reach 20–25 kg/m³·d volumetric loading with no biogas buffer tank, a small footprint and strong shock-load resistance. Paired with DAF, MBR and Fenton polishing up to reuse standards.

Small & Medium Town Wastewater Treatment

For villages and dispersed point sources: SFWT sludge filtration, AAO-HM membrane bioreactor, AAO-DSF aerobic dynamic sludge filtration and sludge self-circulation integrated units — compact footprint, low energy consumption, modular production and unattended operation.

    Two-phase Catalytic Oxidation — Principle & Oxidant Potential

    Based on the Fenton reaction, the process integrates electrochemical coagulation, catalytic oxidation and flocculation-sedimentation. Hydroxyl radicals (·OH) oxidize organics non-selectively and mineralize them into H2O & CO2.
