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.

These systems set the standard for 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 tertiary treatment to get effluent of water reuse quality (5-10 µm) and <5 mg/l suspended solids and <10 mg/l BOD at a rate of 10-15 m3/h/m2.

Alternatively, install the all-in-one Alfa Laval Membrane bioreactor (MBR) system, that combines secondary and tertiary wastewater treatment and delivers a superior effluent quality (effective filtration in sludge to 0.2 µm) suitable for reuse. It removes suspended solids down to <1 mg/l, BOD down to <5 mg/l and handles 5-40 liter/h/m2 filtration area. The gravity driven, pump free and energy efficient design with compact membrane filtration modules (MFM) is based on our patented hollow sheet technology.

Compared to other MBR solutions it offers improved safety, simplicity of operation, plus low operation and maintenance costs.

For some types of industrial wastewater e.g. petrochemicals, chemicals and pharmaceuticals evaporation of anaerobic effluent and crystalization of salty effluents using Alfa Laval AlfaVap and WideGap systems is a good solution.
