Concepts and products for water treatment

We work widely with everything from industrial process water, leachate to storm water, household sewage and drinking water. We can offer proven systems and products for different types of purposes.


A compact solution for vacuum degassing of sewage sludge with simultaneous phosphate precipitation. The technology reduces methane emissions, improves drainage and reduces the phosphate load.


An efficient filter-bottom system that can be built on site or prefabricated. Old filter systems in both drinking water and sewage plants can be easily replaced. Triton® has a single filter-bottom.


A compact cleaning solution with SBR technology. Modular and flexible for optimal results.


The Malmberg Airflo® System is a dissolved air flotation unit. It’s highly efficient for water clarification. It is used in a variety of industrial applications such as dairy-, food-, oil-, pulp- and paper industries but also for general water treatment.

Backflow protection

Malmberg Backflow Protection is a complete unit with reliable and simple performance.

Aeration system

Malmberg bottom aeration system has been carefully planned, from design to installation. The system minimizes energy costs to the lowest possible pressure losses, optimized oxygen control, and a high aeration capacity.


Malmberg Decanting is installed vertically in the sludge settling bassin. It improves thickening by draining off the clear face below the sludge cover.

Plastic chain scrapers

Malmberg Plastic Chain Scraper is designed for use even in extreme environments. The chain is extra strong as well as chemical-resistant which guarantees extra-long service life and minimum wear.

Round sludge scraper

A modular and scalable design of the scraper makes it easy to adapt to different basin volumes. The main components are prefabricated which enables a quick installation. 

Safety hatch

Malmberg Safety hatch can be used both outdoors and indoors. It can also be placed on a wall.  order it either as a double hatch or as a single.
