Category : Water Treatment and Environmental Control

Key Products : ALGAS Microfilter

ALGAS FLUID TECHNOLOGY SYSTEMS AS has over 26 years experience in supplying water treatment plants for the industry, especially the Pulp and Paper Industry, although the concept design has been available and in use for many more years.

Working closely with its customers, ALGAS offers, supplies and commissions a range of unique and effective Microfilter Systems. The size and design of the system is established using experience from the results of Test Filters treating “Live Water” in mill trial conditions and the knowhow from over more than 500 successful installations. Much of the system is made in locally selected fabricating plants with the use of some bought in components. Marketing is affected throughout a network of agents and engineering companies in more than 50 countries world-wide. Distributors have been established in India, Japan, the USA and Canada, and ALGAS GmbH, a daughter company in Düren near Cologne, is operating as a marketing and service company for EU countries and the Middle East. The Microfilter Concept is unique as it is used in most water treatment applications in Pulp & Paper Mills with equal efficiency in all application areas. In some applications previously considered impossible for a “Filter”, the Microfilter Concept has proved that its efficiency makes it possible to replace, for example, the large sedimentation basins used for primary treatment, having only 5% of the installed holding capacity but with 100% of the performance efficiency. Installation is fast and straightforward taking only days rather than months.

Over the years ALGAS has developed its MICROFILTER know how to handle all types of water treatment and producing a quality of clear water to replace fresh water in appropriate mill applications. Over 500 installations worldwide cover applications ranging from treating fresh water, white water for Fibre and Water recovery, filtrate from Screw and Roller Presses, producing a Super Clear water from traditional savealls such as Flotation, Disc Filters & Strainers, through to primary effluent treatment, replacing clarifiers and polishing after final Bio settling for safe discharge. The Microfilter unit itself is compact, easy and fast to install, has low power requirements and is very flexible in operation by being able to cover the wide range of water treatment applications necessary in Pulp & Paper mills.

The company’s vision is to show water treatment really is “profitable” saving millions in recovering for re-use, raw materials, water, energy and power as well as saving chemicals and helping the Environment.

ALGAS Microfilter

The ALGAS Microfilter is basically a drum filter but with features that make it extra special. Filtering from the inside out allows the recovery trough to be installed inside the drum. This means the filter operates with a much higher level compared to conventional designs, increasing filtration time and improving efficiency. No vacuum and only atmospheric pressure is used which gives a soft filtering action, neither pushing nor pulling solids into or through the filtering medium.


This helps easy filter medium cleaning and any solids in the clear filtrate are “microscopic”, making the clear water safe to replace fresh water for re-use.for example on wire showers. Filter cloths types range from 10 micron for special applications, though to 1000 micron for example, in thickening applications. Installation is fast and simple, no drop legs or heavy support work. Little or no chemicals are necessary and the Microfilter is not affected by variations in flow, solids or Ph as are old traditional methods of treatment.
