Wastewater treatment

When less is more

The world is constantly on the look-out for ways to reduce pollution, provide clean water, use less energy and recycle energy already used.

All commercial and industrial activities produce waste products that are harmful to our environment unless treated or processed. Virtually all such activities result in sludge that is normally of little or no commercial value, but is costly to transport. Disposing of such sludge responsibly represents a big challenge.

Alfa Laval provides solutions for removing as much of the solids as possible from wastewater to boost the effectiveness of wastewater treatment, and for drying the sludge as much as possible to reduce transport and disposal costs.

Alfa Laval technologies are available to deal with all kinds of sludge, whether from simple sedimentation, secondary biological treatment or advanced chemical treatment.
