Meva SA Grit Classifier

Mevas SA grit classifier is a highly effient grit classifier developed for grit handling in sewage tretment plants.

DynaSand WWR

DynaSand WWR can be used for final polishing in the final step of the purification of waste water. Due to continuous washing the DynaSand filter can purify waste water with high concentrations of particles, so that you get about 3-4 times higher capacity compared to backwashed sand filters. Washing of the filter media is adapted to load and flow.

DynaSand eVo

DynaSand EVO is a further development of DynaSand filter technology and is particularly suitable when cleaning water with low turbidity, such as ground water treatment and carbon filter installations. The filter sand is washed with water from a nearby filter or supplied via a conduit. Unlike continuous contact filtration no water is produced while washing the sand and like the conventional backwashing filter the sand bed is stationary during filtration. You can combine DynaSand eVo with contact filtration and can always switch to continuous filtration if necessary.
This makes DynaSand eVo optimal to use for groundwater cleaning and untreated water with low turbidity and colour.

DynaSand CF

DynaSand CF provides optimum contact filtration to produce process and drinking water from lake or river water. The flocculant is supplied just before the DynaSand filter inlet and the first part of the filter bed has excellent conditions for quick flocculation and acts as a flocculation reactor. That means you do not need any special flocculation tanks. Thanks to DynaSand’s ability to handle high concentrations of particulate there is no need for additional pre-treatment of the sedimentation.


DynaSand™ is a world-leading continuous sand filter developed by the Axel Johnson Institute in Sweden in the late 1970s. DynaSand is used to clean and produce water for drinking, industrial processes, waste water recycling and waste water treatment before the water is discharged into a recipient. With thousands of filters installed worldwide for municipal and industrial use, we have the experience and equipment necessary to exceed your expectations.
