Wastewater Treatment Facilities | Modular & Custom Solutions

Waste water treatment facilities are engineered sites or packaged systems used to treat sewage, municipal wastewater and industrial effluent before discharge, reuse or further processing. Unlike a single wastewater treatment machine, a complete facility normally combines several treatment stages to remove solids, organic pollutants, oil, grease, nutrients, sludge and other contaminants.
The first stage is usually preliminary treatment. Mechanical grilles, bar screens or solid-liquid separation equipment remove large debris, fibers, plastics, food residues and floating materials. This helps protect pumps, pipelines and downstream equipment. For facilities receiving unstable wastewater flow, an equalization tank can balance hydraulic load and pollutant concentration, making the whole process easier to control.
For wastewater containing oil, grease or light suspended solids, oil-water separation and flotation are often added. A CPI oil water separator can remove free oil from oily wastewater, while a DAF dissolved air flotation machine is suitable for separating fine suspended solids, grease and chemical flocs. With an automatic dosing system, coagulants and flocculants can be accurately prepared and dosed to improve separation performance.
The main pollutant removal stage is often biological treatment. MBBR systems use suspended biofilm carriers to support microbial growth and improve organic matter degradation. MBR systems combine biological treatment with membrane filtration, offering compact layout and higher effluent clarity. For facilities with limited space or stricter discharge requirements, packaged MBR sewage treatment plants can be a practical option. For projects requiring flexible operation and stable performance, MBBR can also be considered.
After biological treatment, wastewater may pass through a clarifier or sedimentation unit. Lamella clarifiers are often used when the project needs efficient solid-liquid separation with a smaller footprint. Sludge generated from flotation, clarification and biological treatment must also be handled properly. Screw press sludge dewatering machines, belt filter presses or other sludge dewatering equipment can reduce sludge volume and disposal costs.
For B2B buyers, planning waste water treatment facilities requires more than selecting equipment by capacity. Important parameters include daily flow, peak flow, COD, BOD, TSS, oil and grease, pH, ammonia nitrogen, phosphorus, temperature, discharge limits, site layout, climate, automation level and maintenance capability. Qingdao Jinwantong can supply single equipment or integrated treatment configurations according to project requirements.
