BWC Modular Steel-Plate Sewage Treatment Equipment | Prefab Sewage Treatment Unit

Working Principle Sewage first enters the pre-settling zone, where large debris is removed, then flows into the biological contact oxidation zone. The tank is filled with three-dimensional elastic media, and microorganisms attach to the surface to form a biofilm. As sewage flows through the media, organic matter is adsorbed and degraded, and ammonia nitrogen and total phosphorus are removed. After that, it enters the solid-liquid separation zone for sludge-water separation, and the clear water is disinfected before being discharged to standard or reused. The whole assembled sewage treatment unit uses blower aeration and runs automatically, making management simple. Application Fields 1.Residential areas: treating household sewage for discharge to standard or reuse. 2.Hotels and restaurants: treating guest room and restaurant wastewater to reduce discharge pollution. 3.Schools and hospitals: treating campus and hospital sewage to lower health risks. 4.Factories and mines: treating domestic organic wastewater to protect the surrounding water environment. FAQ Q1: Where can the BWC modular steel plate sewage treatment equipment be installed? A: It works well for residential areas, hotels, restaurants, schools, hospitals, factories, mines, and similar sites. The unit uses steel plate modules that can be assembled and buried underground, with the surface above used for landscaping or paving—no ground space taken up. It's a good fit for sites with limited space, scattered sewage sources, or where connecting to the municipal sewer isn't practical. Q2: What's the difference between an assembled sewage treatment unit and a standard integrated unit? A: An assembled unit uses steel plate modular tanks that are prefabricated in the factory and put together on site, making transport and installation more flexible. It's well suited for projects with tight spaces or limited transport access. A standard integrated unit is usually molded as one piece, so it's bulkier and has higher transport and lifting requirements. The processes are similar, but the assembled type is easier to install and expand. Q3: Is maintenance on this equipment a hassle? A: Not really. The unit runs automatically and doesn't need someone watching it every day. The main maintenance tasks are checking the blower aeration and media regularly to make sure they're not clogged, and pumping out sludge on a schedule. The steel plate tanks are treated for corrosion resistance, so just check the coating periodically. As long as you follow the procedures, it runs steadily with minimal maintenance.
