The ABT sludge thickener is an efficient and reliable solution for industrial and municipal facilities. It combines modern innovation with proven technology to meet high demands for both environmental performance and energy efficiency.
ABT is a fully enclosed system that serves as the first step in the dewatering process. It can be used as a standalone unit or integrated with equipment such as a screw press, belt filter, or centrifuge for a complete solution.
Separation of sludge and water is achieved through a combination of gravity and gentle static filtration. The process is designed to preserve sludge structure and prevent breakdown, ensuring high-quality thickened sludge.
The machine is available with various types of sludge scrapers, both rotating and static, optimized for efficient drainage. An adjustable sludge ramp at the end of the belt extends retention time and contributes to a higher solids content (TS).
The result is a compact, flexible, and high-performing thickener that provides stable operation and efficient sludge handling.
Process Description
Sludge is first stored in a tank and then pumped into the process using a progressive cavity pump. Flow is adjusted as needed to ensure a consistent feed to the next step.
In the next stage, the sludge is thoroughly mixed with polymer, with dosing based on the sludge’s properties and concentration. Mixing occurs in a mixer where the polymer reacts with the sludge to form flocs suited for further treatment.
The flocculated sludge is then fed to a dewatering table, where the liquid is separated from the solids. Drainage occurs via a belt filter using gravity, allowing solids to remain while water is removed.
Before leaving the belt, the sludge is slowed by an adjustable sludge ramp to extend drainage time and improve thickening. The entire process is designed for continuous operation and can run 24/7.
