Mechanical pretreatment
A basic device for removing solids from wastewater, where raw feed is directed onto a curved plane with slots through which water enters and solids slide down. The design with no moving parts operates by gravity and is widely used in food processing.
Mechanical pretreatment
A device for separating solid elements from wastewater, in which the liquid is fed to a rotating drum consisting a slotted screen, and the impurities are torn off by a scraper. Ttreated water flows through the drum to the drain, and a lance with sprays washes the drum; device is used in many industries
Mechanical pretreatment
An advanced device for separating solid elements from wastewater, in which the inflow is directed to a rotating slotted drum, from where the water escapes through the slots, and the contaminants are removed to the outside. Rotary screens with internal inflow have a wide range of applications from the food industry to plastic recycling.
Mechanical pretreatment
A device for dewatering and compressing solid waste from grates and sieves. It consists of a drum in a pipe with a piston that compresses the waste, the seepage flows out through the slots, and the compressed waste is pushed out up to 6 m. Recommended for waste with fats and oils.
Mechanical pretreatment
Modern device for dewatering and compressing solid waste from grates and sieves. It consists of a drum in a pipe with a screw that transports and compresses waste, and water flows out through holes. The compressed waste is pushed out, and used in many industries.
Mechanical pretreatment
A device for separating solid contaminants, protecting pumps. Installed vertically in pumping stations and collectors. Wastewater leaves the cylinder through perforated walls, and larger impurities are carried away by the screw. Vertical sscreens are more reliable than basket screens.
