Waste Water Treatment Systems | Custom MBR, DAF & Clarifiers

Waste water treatment systems are used to treat wastewater before discharge, reuse or further processing. They are widely applied in municipal sewage treatment, industrial effluent treatment, commercial wastewater projects, oily wastewater separation and packaged sewage treatment applications. A proper system helps reduce pollutants such as COD, BOD, TSS, oil and grease, ammonia nitrogen, phosphorus, odor and sludge volume.
A complete wastewater treatment system usually starts with pretreatment. Mechanical grilles or screens remove large solids, fibers, plastics and floating debris to protect pumps and downstream equipment. For wastewater with uneven discharge, an equalization tank can balance flow and pollutant concentration, making the following treatment stages more stable.
For industrial wastewater containing oil, grease or light suspended solids, oil-water separation and flotation are often required. CPI oil water separators can be used for oily wastewater treatment, while DAF dissolved air flotation machines are suitable for removing fine suspended solids, grease and chemically formed flocs. Chemical coagulation and flocculation can be added through an automatic dosing system to improve separation performance.
The core of many systems is biological treatment, which removes organic pollutants through microbial activity. MBBR wastewater treatment systems use biofilm carriers to improve biological degradation and resist load fluctuation. MBR sewage treatment systems combine biological treatment with membrane filtration, offering compact layout and high-quality effluent. For packaged sewage treatment plants, MBR and MBBR are commonly selected according to effluent target, footprint, operation requirements and project budget.
After biological treatment, clarification or solid-liquid separation may be needed. A lamella clarifier can improve sedimentation efficiency in a smaller footprint compared with conventional settling tanks. Sludge generated from flotation, clarification and biological processes can be treated by screw press sludge dewatering machines, belt filter presses or other sludge treatment equipment to reduce moisture content and disposal cost.
For B2B buyers, selecting the right system requires more than choosing a product name. Important parameters include wastewater source, daily flow, peak flow, COD, BOD, TSS, oil and grease, pH, temperature, nutrient levels, required discharge standard, land area, climate, automation level and maintenance capacity. Qingdao Jinwantong can provide single equipment or integrated waste water treatment systems based on project conditions.
