A sand filter is a mechanical device used for wastewater and water treatment, primarily designed to remove solids and suspended particles from liquids. It consists of a container filled with a layer of specialized filter sand.

The wastewater or water is passed through the sand, where particles are trapped and retained in the sand. As filtration occurs, the water becomes clearer, as both coarse and fine impurities are left behind in the sand. Sand filters are effective, low-maintenance, and commonly used in treatment plants, swimming pools, and drinking water purification. They play a crucial role in improving water quality by removing suspended solids, algae, and other contaminants.

Performance: from 5m3/h up to 1,000m3/h

Sand filter, active carbon filter etc.

Dissolved air flotation is a wastewater treatment process used to remove solids, oils, and fats. In this process, the wastewater is first saturated with air under pressure. Then the pressure is suddenly reduced, causing fine air bubbles to form. These bubbles attach to the contaminants and float them to the surface, where they can be skimmed off as foam. This efficient process improves water quality and is commonly used in industrial applications.

Capacity: from 5 to 1,000m3/h

Design: vertical, horizontal, with/without slats, operated with compressed air or nitrogen

A drum screen in wastewater treatment is a device used to remove solids from wastewater streams. It consists of a rotating cylindrical drum with perforated or mesh walls. Wastewater is fed into the drum, and as it rotates, smaller particles pass through the openings while larger solids are retained and discharged at the end. This system is particularly efficient for the preliminary treatment of wastewater, helping to remove larger contaminants and reduce the load on subsequent treatment processes.

Capacity: from 5m3/h to 1,000m3/h

Screen slott: 0.25-2.00 mm

A polymer preparation station is a specialized facility in wastewater treatment that is used to produce a polymer solution. These polymer solutions are commonly employed to enhance the dewatering of sludge and promote the formation of larger flocs, which can be more easily separated.

In the station, the polymer is dissolved in water, with the precise dosing and mixing time being crucial for effectiveness. The resulting solution is then introduced into the treatment process to optimize solid removal. Polymer preparation stations play an important role in wastewater treatment, as they enhance the efficiency of subsequent processes and can reduce overall operating costs.

Capacity: 500-10.000l/h
