Industrial wastewater treatment
Industrial wastewater varies considerably in specification, depending on type of industry and local habits. In many cases it is not accepted by the municipal wastewater treatment plant, so pre-treatment or complete on-site treatment is needed. Alfa Laval offers several compact, easy-to-operate wastewater treatment technologies that produce clean effluent either for discharge or further treatment for water reuse.
On-site industrial wastewater treatment – also an untapped water resource
Alfa Laval technologies for biological treatment of industrial wastewater are ideal for removal of nutrients, organic matter, fats, oil and grease (FOG), and other undesirable substances and micro particles. They are characterized by high efficiency, flexibility and small footprint – with all steps in the same tank.
Where influent flow and organic loads vary and effluent requirements are stringent, the Alfa Laval AS-H Sequencing Batch Reactor (SBR) with our patented floating decanter is a good choice for secondary biological treatment. Combine it with the Alfa Laval AS-H Iso-Disc® Cloth Media Filter for

Wastewater - an untapped water resource
More and more realise that wastewater can also be a valuable water resource. There are many good reasons to consider reusing biologically treated municipal and industrial wastewater: Increase water resources, reduce intake of new water and limit effluent flow loads to sewers.
Reclaimed water can be used for numerous applications e.g. industrial process water, cooling towers and wash water; surface irrigation of crops, vineyards and golf courses; recreation lakes, wetlands, wildlife habitat and stream augmentation and ground water recharge.
Water treated with Alfa Laval MBR and AS-H Iso-Disc filtration systems can even be used as potable water if a final polishing step e.g. UV radiation, ultrafiltration, nanofiltration, reverse osmosis, active coal, ozone or chlorine is added.
