SweWater/wastewater treatment
In municipal and industrial treatment plants, large volumes of sludge are generated that must be treated before it can be transported, stored, or further processed. For the process to operate efficiently, solutions are required that can handle the entire chain - from separation and thickening to dewatering and transport.
Autofric offers a complete range of equipment for sludge handling in water and wastewater treatment processes. With extensive experience, robust solutions are developed and manufactured for efficient handling of sludge and residual products.
Sludge Screening
In many facilities, the first step is to separate larger particles and fibrous material from the sludge. For this purpose, equipment such as the Sludge Cleaner ASC is used - an energy-efficient in-line screen press for the separation and dewatering of solid particles from sludge flows.
Sludge Thickening
After separation, the sludge needs to be thickened to reduce its volume prior to final dewatering. Autofric’s Sludge Thickener ABT is designed to efficiently concentrate sludge and create better conditions for subsequent treatment.
Sludge Dewatering
Sludge separated from wastewater in the initial stages of the treatment process contains resources in the form of energy and nutrients, but also toxins that can harm the environment.
At wastewater treatment plants, sludge is digested to produce biogas and reduce sludge volume. However, large amounts of digested sludge still remain, which are costly and energy-intensive to manage.
Through effective dewatering, sludge volume can be drastically reduced, resulting in significant savings in handling and transportation costs. Dewatering also facilitates the removal of environmental contaminants from the sludge.
Dewatering is often carried out mechanically and can be performed in several ways. One effective method is to use a screw press to extract water from the sludge. The water is returned to the treatment process, while the dewatered sludge is collected and disposed of.
Autofric’s ASP screw press is designed for efficient and energy-saving dewatering of wastewater sludge from treatment plants and industrial processes.
The sludge press operates using a rotating screw that forces the sludge through multiple dewatering zones, separating liquid from solid particles. The design ensures stable operation, low energy consumption, and minimal maintenance.
Transport of Dewatered Sludge
After dewatering, the sludge must be transported for storage in containers or further handling. Autofric’s screw conveyors are used to transport sludge, sand, and other bulk materials both horizontally and vertically within the facility.
The conveyors are robust, energy-efficient, and can be customized to suit each facility’s layout and capacity requirements. The enclosed design also reduces odors, dust, and spillage during transport.
Autofric’s Type-E screw series transports and distributes the separated sludge, both horizontally and vertically, to containers or sludge storage facilities.
