Description
Belt thickeners can be used not only for thickening municipal and industrial sewage sludge. They are also widely used for sludge thickening in various industries. These thickeners are designed to provide high throughput for the removal of liquids from solid and liquid slurries (sludge). They are simple in design, made of stainless or galvanised steel and have a low space footprint. They are versatile and can be adapted to a wide range of sludge treatment methods, reducing the cost and hassle of sewage sludge management.
Advantages
- High throughput and low energy consumption. Adapted pneumatic or hydraulic belt centring, large belt working surface and specially designed ploughs allow efficient control of the sludge dewatering process. This design ensures that sludge dewatering will be carried out using less polyelectrolyte and less electricity.
- Optimisation and cost savings The possibility to integrate this thickener in cascade structures with other sludge treatment equipment offers great practicality and efficiency. This allows optimisation of the use of the plant and considerable space and cost savings, as no additional thickeners need to be installed.
- Wear resistance and durability. The hot-dip galvanised steel or stainless steel housing ensures that the belt compactor is resistant to wear. And many years of experience in the design and manufacture of these units guarantee flawless performance.
- Automatic polymer dosing system. The option of an automatic polymer dosing system ensures the optimum amount of polyelectrolyte during the process. This allows efficient control of the flocculation and sludge dewatering process and saves operating costs.
- Easy maintenance and servicing. The belt filters are robustly constructed and have easily accessible parts. You can efficiently and quickly carry out the necessary servicing work and ensure the continuous smooth running of the process.
- Low noise levels. This press has a quiet operation, which is important for the comfort of the working environment. This significantly increases the efficiency of the workforce and reduces disturbance to the working environment.
- Cost-effective and sustainable. By separating the leachate and the wash water, the leachate can be reused as wash water, ensuring economy and sustainability.
How it works
The main purpose of a sludge thickener is to reduce the volume of sludge before further sludge treatment steps. These OCM belt thickeners work on the principle of gravity by filtering the sludge to be thickened through a special fabric.
After the sludge is flocculated in the feed pipe, the sludge is smoothly fed onto the filter belt via a feed chute located above the tension shaft. The distribution plate ensures even distribution over the entire working width of the belt, separating most of the liquids and solids. The belt thickeners are equipped with several rows of adjustable ploughs which create channels in the flowing mass, facilitating the drainage of water away from the sludge mass and helping the sludge to thicken.
A slow-moving filter belt transports the sludge to the discharge point, where the thickened sludge is shaken off the belt and into a conveyor. The water separated by flocculation drains off automatically and can be reused for washing. The special fabric belt is cleaned by a washing chamber with flat jet nozzles.
The nozzle with a self-cleaning device collects the washing water separately. The thickened sludge is already ready for recycling using dewatering equipment.
