High-end sludge treatment solutions for demanding applications

DEWACO LTD offers solutions to the world's most complex sludge treatment problems. The company can also help to reduce environmental impacts and substantially improve efficiency in producing bioenergy from waste.
The company provides complete sludge thickening, dewatering and sludge removal systems. Its combined process technology in sludge treatment has been successfully implemented in both municipal and industrial applications. All products are designed for a long and reliable working life demanding minimal operational and maintenance costs. In addition, DEWA equipment can be easily integrated into existing systems.

DEWA NPD XL Belt Filter Press is the most flexible solution for any sludge dewatering application. It has an independent “Extra Large” gravity deck which allows users to adjust the belt speed of the gravity section independently enabling to achieve higher solid consistency prior to dewatering. It is also possible to select four different belt routes for the pressing belts, a feature which further increases the flexibility of the product.

DEWA Chain & Flight type sludge and scum collectors are designed to operate in longitudinal clarifiers. In addition to municipal water and wastewater application, they can be use DAF, API tank and desalinations applications.

DEWA BTN L Heavy Duty Gravity Belt Thickener is a total enclosed unit designed to considerably increase the solid content of the sludge. The monocoque design feature enables odour containment within the unit and simplifies odour extraction via the vent pipe mount on the top cover. This revolutionary design concept offers a clean, odour-free and operator friendly environment.

DEWA FPD multi-stage series sludge dewaterer is a combination of a BTN (heavy duty belt thickener) and a FP (belt filter press), and is designed for the most demanding, large capacity applications. The FPD multi-stage dewaterer is easy to modify according to the characteristics of the sludge and throughput and cake solid requirements.

CAVIA facilitates the extracttion of valuable materials and energy from sludge. During the sludge handling process, CAVIA generates an improved biogas yield of up to 40%. This increased source of free, renewable energy that can be used on site or resold to the grid has a major impact on net profit and an equally significant effect on emissions, reducing them drastically.

Dewaco's vision and mission is to be an international player in the field of sludge treatment equipment and solutions and to continually develop and deploy the highest quality sludge water treatment systems in the world.
