Sand washing/sand dewatering
This is the mechanical cleaning equipment of wastewater treatment plants, which is located generally after the mechanical screen, and it separates the sand content of waste water from which the screenings have already been removed.
It handles and dewaters the sandy sludge of the sand trap facility in case of large quantities of waste water. The equipment includes an inclined auger having no shaft for removing the sand, which seats on a wearing plate. It can be supplemented also with a sand washer unit if required, which reduces the bacteria content of the sand, thus mitigating the risk of infection.
