The (Archimedean) Screw Pumps are well-known for their excellent qualities such as the Simple & Rugged design, the high efficiency, the capacity to pump raw water(even when it contains an amount of solids and debris) and their lifetime reliability.

The SMC consist in a Stainless Steel frame, developed for a “in channel” installation with 75° inclination. The filtration zone, placed in the bottom part, is made by equidistant stainless steel bars.

The coarse waste present in the waste water, are blocked by the bars of the filtering zone and accumulate in the bottom of the frame until, the consequent increase of water level, active the cleaning system through rakes.

The system WAU – COMBINED PRE-TREATMENT UNIT is the answer to the intrusive and too costly in concrete pre-treatment stations.

Our WAU3 – COMBINED PRE-TREATMENT UNIT is a “state of the art” combined unit of waste water pre- treatment, designed to fulfill three functions at the same time (filtration, sand removal and grease removal) into a single, convenient and reliable stainless steel machine.

As Biogas generally called, are all gases which result from microbial degradation of organic matters under anoxic conditions (under exclusion of oxygen). In addition to the classical biogas, there is also digester gas from sewage treatment plants as well as landfill gas, which results from fermentation of solid biomass/bio-waste, food leftovers, organic fertilizers, plant remains and energy crops.
