Our solutions

Our products and solutions are developed and manufactured based on solid experience in the field of wastewater. AL-2 Teknik started producing belt filters more than 25 years ago, which is still our core product, included in many of our solutions.

Mechanical filtration

AL-2 Belt Filter

Effective continuous filtration of process water and wastewater. Robust self-cleaning solution with endless Belt filter mesh from 30 µm to 5000 µm. Compact design in different sizes. Ideal for modular construction to accommodate large volumes of water.

Chemical-mechanical cleaning

AL-2 Separation System

Advanced wastewater treatment by combining chemical precipitation and filtration on AL-2 Belt Filter. Continuous separation process for removal of solids, organic matter, polluting particles, heavy metals, fats, oils, greases etc.

Continuous removal of carbon

AL-2 Carbon Harvester

Belt filter technology for removal of carbon in the water inlet of wastewater treatment plants. Continuous reduction of organic matter. The carbon is ideal for biogas. The solution creates economic and environmental benefits for both existing and new wastewater treatment plants.

Increased sludge dry matter content


AL-2 Sludge Dewatering

Sludge treatment system for increasing dry matter content in sludge. Continuous process with separation of sludge and liquid phase followed by sludge dewatering. Minimizing the sludge volume reduces costs of transporting and disposing of sludge through a low energy process.
Reduce transportation and disposal costs through a low energy process.

Dosing of liquid polymer

AL-2 Polymer System

Fully automatic and reliable polymer dosing and make up unit. Precise dosing of liquid polymer and dilution with automatically regulated water volume, with an optimum maturation phase.

Water polishing


AL-2 Media Filtration

Unique results with 1 micron filtration through Dryden AFM-media. Advanced automation ensures reliable and consistent results. Ideal for polishing and reuse of the water treated in the AL-2 Separation System.
