A pressure-bearing integrated unit is a water treatment system built inside a closed tank and operating under pressure. The fully enclosed integrated water filter is a common version of this—raw water goes through reaction, settling, and filtration and comes out as pressurized clean water, so there's no need for a clear water tank or a secondary pump station. The fully enclosed design keeps outside contamination out and prevents algae growth. It takes up far less space than a traditional plant, and once the inlet and outlet pipes are connected, it ties straight into the water network.

Raw water enters the pressure-bearing integrated unit and mixes with coagulant to form small flocs. It then flows into the settling zone, where the flocs sink to the sludge hopper under gravity. The clear water rises into the filtration zone and passes through a quartz sand or anthracite bed, where suspended solids are trapped. The key feature of the fully enclosed integrated water filter is that the whole process happens inside a sealed, pressurized tank. Inlet pressure pushes the water through the media, and the treated water still has enough pressure to go directly into the supply network. After the bed runs for a while, a built-in automatic backwash system cleans it and restores filtration capacity.
Application Fields
1.Township water supply: ties directly into the network, skipping the clear water tank and secondary pumping—good for small centralized stations.
2.Residential secondary supply: handles water quality swings and keeps pressure and safety steady for high-rise residents.
3.Industrial circulating water: side-stream filtration to remove suspended solids and keep water quality stable.
4.Food and beverage: pre-treatment for production water to reduce turbidity and impurities.
FAQ
Q1: How much pressure can a pressure-bearing integrated unit handle?
A: Standard design pressure is 0.4–0.6 MPa, and special models can go up to 1.0 MPa. The tank is usually coated carbon steel or stainless steel, around 8–10 mm thick, so it handles network pressure directly. A booster pump is only needed if the inlet pressure is too low.
Q2: How often does the filter media in a fully enclosed integrated water filter need to be replaced?
A: Quartz sand or anthracite usually lasts 3–5 years and is maintained through regular backwashing. For iron- and manganese-bearing groundwater, a catalytic film forms on the media, so it doesn't need replacing unless it cakes up. The actual cycle depends on influent quality and how well backwashing is working.
Q3: How does it compare with a traditional open concrete tank?
A: The fully enclosed design keeps outside contamination out and prevents algae growth. Running under pressure eliminates the clear water tank and secondary pump station, so the footprint is just a fraction of a conventional plant. It works once the pipes are hooked up—a good fit for sites with limited space or projects that need to get running fast.
