Our Services
Our Services
Complete wastewater treatment services, from consulting and design through installation to after-sales support, delivered to perform in real-world conditions.
Sludge Dewatering & Drying
Reduces the volume and moisture content of sludge from wastewater treatment systems, making it easier to store, transport, and dispose of while cutting long-term handling costs.
Evaporation & Zero Liquid Discharge
Technology that reduces wastewater volume and recovers water for reuse, efficiently minimizing or eliminating liquid discharge from your production process.
Preliminary & Primary Treatment
Screening and removal of solids, grease, and initial contaminants to reduce the load on downstream treatment stages.
Advanced Wastewater Treatment
Elevate water quality with specialized treatment technologies that remove complex contaminants and meet stringent water-quality standards.
Water Reuse & Recycling
Restores used water to a quality fit for reuse across your processes, reducing fresh-water consumption and improving water resource management.

Our Products
Featured Products
Wastewater treatment machinery trusted by industrial customers, built to cut costs, boost efficiency, and perform in real plants.
DEWATERING
Decanter Centrifuge
Decanter Centrifuge is a centrifugal sludge dewatering machine that separates solids and liquids by high-speed centrifugal force. It handles sludge concentrations of approximately 2,000–30,000 ppm and produces a dry sludge cake of approximately 20–30% DS. It operates continuously in a closed system and supports high throughput in a limited space, suitable for industrial applications requiring speed and continuous operation.
DEWATERING
Sludge Dryer
Sludge Dryer/Low-Temperature Sludge Dryer is a sludge drying machine using a heat pump at temperatures below 70°C, helping reduce the weight and volume of sludge, with a heat recovery system to save energy. The closed system helps control odour and vapour, leaving the sludge dry, easy to handle and extendable towards a Zero Liquid Discharge (ZLD) approach.
DAF
Rectangular DAF
Rectangular / Horizontal DAF is a dissolved air flotation system for primary wastewater treatment, helping separate FOG and SS and reduce BOD/COD with microbubbles that carry the sludge up to the water surface. It can reduce FOG/SS by more than 90%, BOD by more than 30% and COD by more than 20%, supporting flow rates of 1–1,000 m³/hr, and integrates the Coagulation–Flocculation system and the bubble generation unit into a single platform. The structure can be selected as either FRP-coated steel or SUS304/316.
EVAPORATOR / CRYSTALLIZER
Evaporator Crystallizer
Evaporator Crystallizer, an evaporator and crystallizer for the final stage of the Zero Liquid Discharge (ZLD) system. It uses vacuum to concentrate wastewater up to the saturation point in order to separate salts and solids as dry crystals, while recovering almost all of the distillate for reuse, enabling the system to achieve complete Zero Liquid Discharge. Suitable for wastewater with high TDS and a high solids content, using a Scraped Surface system to reduce scale build-up on the heat exchange surface.
MBR MEMBRANE
Membrane Bioreactor
Membrane Bioreactor combines biological treatment and membrane filtration in a single tank, replacing the sedimentation tank and producing high-quality clear water. Suitable for wastewater treatment systems and water reuse, it supports Flat Sheet and Hollow Fiber membranes with a pore size of 0.03–0.1 μm, made of PVDF, PES and PTFE, which are hydrophilic and fouling-resistant, efficiently filtering out TSS and bacteria.
