We design and manufacture high-performance wastewater treatment systems for municipal authorities and industrial clients worldwide. From MBR membrane bioreactors to sludge dewatering equipment — engineered to last.
Our Equipment
From biological treatment to advanced filtration — our equipment covers every stage of the water treatment process with proven efficiency.
Combines biological degradation with ultrafiltration membrane separation for superior effluent quality. Ideal for reuse applications and tight discharge standards.
High-efficiency removal of suspended solids, fats, oils and greases from industrial wastewater. Customizable for food processing, paper, and petrochemical plants.
Continuous, low-energy sludge dewatering with minimal operator attention. Self-cleaning filter screens reduce maintenance intervals and operational costs.
Eliminate persistent micropollutants, pharmaceuticals, and disinfection byproducts. Our AOP systems meet the strictest WHO and EU drinking water standards.
Fully integrated, factory-tested treatment plants in standard shipping containers. Rapid deployment for remote sites, emergency response, and modular expansion.
Hollow-fiber UF and spiral-wound NF systems for advanced water polishing, desalination pre-treatment, and water reuse projects. Long membrane lifespan.
Solutions By Sector
Our treatment systems are engineered to address the specific wastewater challenges across municipal, industrial, and commercial sectors.
End-to-end solutions for city and regional wastewater treatment plants — from primary screening to nutrient removal and effluent reuse.
Custom treatment systems meeting local discharge standards for heavy industries. We specialise in zero-liquid-discharge (ZLD) solutions.
Compact, quiet-running systems ideal for hotels, resorts, hospitals, and campuses that require on-site wastewater treatment and water recycling.
Our Approach
We guide every project through a proven five-step process — ensuring the right solution, delivered on time and within budget.
Submit your influent data. Our engineers analyse pollutant loads and set target effluent standards.
We develop a tailored treatment flowsheet, equipment selection and P&ID drawings.
In-house fabrication with ISO-certified quality control, FAT testing before shipment.
Worldwide logistics support, on-site installation assistance and commissioning by our team.
24/7 remote monitoring, spare parts supply and annual maintenance contracts available.
