Disc Filter for tertiary treatment filtration
Designed for the filtration of large volumes of wastewater, the compact system has the capability to filter high flows (volumes) of liquids.
- Utilities and municipal wastewater
- Industrial trade effluent
Why choose a WPL Disk Filter:
- Low power consumption – gravity flows save energy costs
- Simple removal and replacement of filter cartridge
- Compact unit with a high filtration quality that delivers high flows up to 500 L/s
- Enables filtration from 10μm up to 200 μm mesh size
- Installed above ground in steel tanks or below ground in concrete channels
- Units can be put into operation immediately after installation
- Suitable mainly for tertiary filtration treatment removing undissolved material
- Fully automatic operation which includes a programme with pre-set operation parameters
- Filtration runs continuously without interruption.
Filter applications include:
- Treatment of effluent water
- Pre-treatment before Ultra Violet (UV)
- Pre-treatment of potable water
- Cooling water in various industries
- Inlet process water
- Recovery of valuable materials in different types of industry
- Industrial waste water treatment such as fish farms, paper industry, food and drink process
Option of hire and trials:
Fast and flexible hire of WPL’s wastewater treatment units ensures that sites undergoing emergency reactive work, or planned refurbishment, can remain fully operational and within environmental consent. Whilst WPL’s full-scale operational trials provide a fast and effective solution, offering immediate enhancement to onsite industrial trade effluent treatment. This means full compliance is achieved as soon as possible, with no capital risk, putting your mind at ease while a permanent option is found.

How the Disc Filter works
Waste water flows by gravity from the central drum through filtration segments. The filter drum is idle at the beginning of the filtration cycle – it does not rotate. Suspended solids get caught on the inner side of the segments covered by a filter cloth. As the cloth gradually becomes clogged with suspended solids, the water flow through the cloth decreases and water level inside the drum gradually increases. Water level probe activates the rotation of the filter discs and in the same time the backwash system is turned on.
High-pressure backwash rinses impurities off to the sludge manger. The water level inside the drum decreases, the flow is again at its peak with minimum water level. The filtration cycle repeats. Filtration proceeds continually without interruption.
