Working principle

This rotary disc filter consists of multiple filter discs arranged horizontally, each with a fan-shaped filter plate covered by a fiber filter cloth with 10 μm openings. Its operating procedures involve filtration, backwash and sludge discharge.

  • 1. Filtration

    Sewage travels to the filter tank through gravitational force, and a water distribution weir is positioned within the tank. The filter cloth is entirely submerged and allows the sewage to flow through from the outside in. Then, with gravity, the fluid travels from the outlet weir and out of the filtration system as one consistent process.
  • 2. Cleaning

    Sewage travels to the filter tank through gravitational force, and a water distribution weir is positioned within the tank. The filter cloth is entirely submerged and allows the sewage to flow through from the outside in. Then, with gravity, the fluid travels from the outlet weir and out of the filtration system as one consistent process.
    To ensure efficient cleaning operations, an alternate cleaning mode is used. The suction pump works continuously, switching automatically between two filter discs every two cycles. In the event of decreased water quality or a rapid increase of liquid levels in the tank, all backwash pumps will automatically activate at the same time to clean several groups of filter discs until normal operations are restored.
  • 3. Sludge discharge system

    This sludge discharge system has been constructed with a funnel-shaped container base. By collecting the sludge at the bottom, this minimises the amount of build-up on the filter material, meaning the filtration process is extended and the amount of backwash water needed is reduced. The sludge pump sends the sludge back to the wastewater treatment network through the sludge discharge pipe which has been perforated at the bottom of the tank. The interval and duration of the sludge discharge can all be adjusted.

Features
  • The quality of the wastewater is stable and the filtration is effective, allowing it to withstand an influx of up to 60-80mg/L of suspended solids (SS). When the SS input is at or below 40mg/L, the effluent SS output is kept to 10mg/L or less.
  • With its minimal size and low energy consumption, this filter helps to reduce both space and costs.
  • The waterhead loss remains minimal, guaranteeing that the water flow and pressure stay consistent, with the head loss between the states not exceeding 300 mm.
  • Automation can help reduce manual labor and the associated costs.
  • The use of modular design in combination with swift filter cloth replacement can dramatically reduce maintenance and repair expenditure.
  • This filter features filter cloth with a special weaving technology, providing increased resilience and superior filtration precision. The microfilter diameter range is 5-20 μm and can be chosen depending on the need. This allows for an effective filtering of small particles and an improved quality of the water. The fiber surface is smooth and prevents dirt build-up, while also featuring excellent corrosion resistance and the prevention of mildew. These traits ensure the longevity of the filter cloth and stability in water quality.
