Water & wastewater Treatment Solutions
Longdai provides customized treatment solutions for municipal wastewater, industrial wastewater, sludge treatment, water reuse and purification projects, with process design, equipment configuration and EPC services based on actual project requirements.
Longdai's solution is configured to each project's water quality, treatment scale, discharge standards, reuse requirements, and site conditions. Our solutions cover domestic and municipal sewage, industrial wastewater, construction slurry and sludge treatment, pure water production, and reclaimed water reuse. We combine pretreatment, biological treatment, solid-liquid separation, sludge dewatering, advanced treatment, and membrane treatment to suit actual operating conditions wherein we support each project from process design and equipment configuration to installation, commissioning, and EPC delivery.

Capacity: 10–50,000 m³/dMunicipal Wastewater Treatment SolutionLongdai’s solutions for municipal and decentralized wastewater treatment projects are designed around each project's treatment scale, influent quality, effluent standard, site conditions, and reuse needs which run from process design and equipment configuration to installation and commissioning. Treatment capacities range from 10 to 50,000 m³/d.
-
Capacity: 50–20,000 m³/dIndustrial Wastewater Treatment SolutionThe pollutants in industrial wastewater and the treatment requirements are closely tied to the production process, which may include oils, heavy metals, high-concentration organics, salts, color, and refractory substances. We design the process and configure the equipment according to the wastewater source, flow, water quality, target pollutants, discharge standards, and reuse requirements.
-
Slurry capacity: 30–500 m³/h Sludge capacity: 5–500 tDS/dSlurry Treatment SolutionSlurry or sludge from different sources differ greatly in sand content, moisture content, organic matter content, and dewatering performance. As such separation, thickening, conditioning, and dewatering processes are configured to the sludge characteristics and the final disposal requirements.
-
Pure water capacity: 0.5–200 m³/h Reclaimed water capacity: 50–20,000 m³/dPure Water and Water ReuseLongdai provides water treatment solutions for different water source conditions, target water quality, and reuse purposes. The process runs from raw water pretreatment, softening, ultrafiltration systems, and reverse osmosis systems to electrodeionization (EDI) for deep desalination.
-
Capacity: 1,000–100,000 m³/hAir Pollution and Odor ControlExhaust gases from different production and environmental facilities differ greatly in pollutant composition, concentration, air flow rate, humidity, and variability. As such treatment solutions are combined and configured to the actual characteristics of the waste gas.
