AL-2 Belt Filter
Efficient mechanical filtration of process water and wastewater.
AL-2 Belt Filter
Market-leading belt filter
The AL-2 Belt Filter is market-leading. Our belt filter is used for filtration of process water or wastewater, where we effectively remove particles when the water gravitates through the filter mesh. The self-cleaning belt filter is operated by automatic start-stop, where the endless filter belt carefully removes the particles from a continuous flow.
AL-2 Teknik started producing belt filters more than 25 years ago, and the many years of experience and development have made our belt filters efficient and reliable. The operational reliability is of high importance when it comes to treatment of wastewater. AL-2 Teknik offers servicing, maintenance and spare parts.
About the belt filter
The degree of filtration depends on the application. We deliver filter belts with mesh apertures from 30 μm to 5000 μm (0.03 mm to 5.00 mm). It gives a wide applicability and the possibility to filter everything from:
– Wastewater in food and dairy
– Recirculated water in zoological gardens
– Aquaculture (land-based and offshore farms)
– Inlet screening at municipal wastewater treatment plants for effective removal of inorganic matter such as cotton buds and fiber belts, which are unwanted at the wastewater treatment plants.
At municipal wastewater treatment plants, we can also – in a very energy-efficient process – remove organic matter, which is ideal for biogas production and at the same time save energy for aeration and retention of microplastics.
Compact, gentle and automatic filtration
AL-2 Belt Filter has many advantages:
- Compact with internal drum motor
- Continuous operation with endless belt
- Interval operation for build-up of filter mat
- Gentle removal of particles and impurities
- Combined filtration and dewatering
- Automatic cleaning of the belt
- High level of reliability
- Cost-effective with low energy use
- Low noise level
- Automation with level sensors, flowmeters, and PLC-control is offered
The AL-2 Belt Filter is made of stainless steel AISI 304 or AISI 316 supplemented by plastic material parts, which provides a product that is resistant in most environments.
The AL-2 Belt Filter is made from corrosion resistant materials such as stainless steel AISI 304, AISI 316, PE, PP etc, suitable for the environment where they will be employed.
The belt filter can be delivered in a filter tank adapted to the individual application or installed in concrete channels constructed according to AL-2 specifications. Standard filter tanks are available in various configurations and are made of PE or PP plastic. Customer-specific solutions are also available, e.g. special inlets and outlets or manufacturing in stainless steel.
The AL-2 belt filter is available in several standard models, chosen dependent on use, flow, space, etc. It is possible to install more belt filters in a parallel setup for high flows. All models are based on the same AL-2 design, which makes them equally efficient, reliable, and useful.
Automatic cleaning of the belt filter provides a continuous and effective filtration. Different solutions for scrapers and backwash make it possible to choose the optimal belt cleaning.
AL-2 Teknik carries a large stock of belt for all standard models within all mesh ranges. It gives great flexibility for our customers, as this allows us to dispatch parts very quickly when required.
