Sludge dehydrator descriptions

DAGYEE machines for sludge dewatering: Reliable and efficient methods of sewage sludge dewatering by means of screw presses and belt filter presses.

Sludge produced in municipal and industrial wastewater treatment plants requires dewatering prior to further treatment or utilisation. In view of increasing sludge disposal costs it has become necessary to concentrate the sludge to a high solids content.

DAGYEE offers for this purpose commonly known systems for continuous sludge dewatering, e.g. belt filter presses and screw presses.

Sludge dehydrator process

A screw press (SP) provides sludge dewatering by conveying the sludge along the inside of a permeable cylinder. It is based on a slowly-rotating (~5 RPM) Archimedean screw within a cylindrical screen (otherwise termed drum filter/screen or basket). It is normally inclined by ~20° to the horizontal to assist with the draining of water into the sump. The screen generally has an aperture rating below 0.5 mm and is based on wedge-wire or occasionally perforated metal.

The screens are less susceptible to clogging than the filter media used for other thickening and dewatering processes. Consequently, spray-cleaning is applied only intermittently for around 2−4% of the operating time.

As with all thickening and dewatering processes, the product solids (or cake) content is dependent on the feedwater sludge quality. The cake solids content has been shown to be inversely proportional to the volatile solids (VS) of the feed sludge.

Sludge dehydrator advantages

Efficient Dewatering

The machine employs a screw press mechanism that applies gradually increasing pressure and compression to the sludge. This results in effective water extraction, leading to high dewatering efficiency. It helps reduce the moisture content and the volume of sludge, resulting in lower transportation and disposal costs. Moreover, the machine can operate independently or multiple units work together.

Compact Design

The machine is designed with a compact structure, occupying small space so that it can easily work with existing wastewater treatment systems. Besides, the modular design makes it easy to install and maintain.

Continuous Operation

The machine operates continuously, allowing for a consistent and uninterrupted dewatering process for 24 hours. It can be automatic, with low maintenance and monitoring needed.

Low Energy Consumption

The slow rotation speed of the screw press, typically ranging from 1 to 4 RPM. It requires lower energy consumption compared to high-speed centrifuges or belt filter presses, which helps to reduce operation costs.

Great Durability

The entire machine is built with 304 stainless steel, including the movable and fixed plates, screw press, flocculation mixing tank, metering tank, control box, casing and frame. Especially, the screw press and blades are wear-resistant and heat-treated to prolong its service life. And the entire machine is under a one-year warranty.
