Sludge generation is an important part of the water and wastewater treatment process, since inadequate sludge handling system can lead to serious environmental problems.

The DEWA N-PD belt filter press is the most flexible solution for any sludge dewatering application. It has an independent gravity belt thickener which allows users to adjust the belt speed of the gravity section independently. It is also possible to select four different belt routes for the pressing belts, a feature which further increases the flexibility of the product.

The DEWA P-C “Mini” sludge dewatering unit is ideal for small scale sludge dewatering applications in both municipal and industrial treatment plants. This twin belts design has a small gravity drainage section followed by wedge and pressing sections.

DEWA provides both spiral shaftless conveyors as well as belt conveyors depending on customer requirements.

The programmable control panel can accommodate individual facility requirements. Optional equipment is available for severe (e.g. profibus) environments.

For sludge and scum collection and removal we offer chain & flight-type chain scraper systems. These are the most sophisticated systems for sludge and scum removal from rectangular settling tanks. Chain Scraper Systems can be used in multiple application basin types.

DEWA flocculator is used for water and wastewater clarification and to optimal formation of flocs. In sludge dewatering, it is essential to precondition the sludge with the polymer prior to dewatering. DEWA flocculator is designed to obtain the best possible formation of the flocks. It is easy to combine with other machines and equipment.

This versatile, economical and powerful belt filter press with integrated belt thickener is our most popular sludge dewatering unit for municipal and industrial applications with unbeatable price-quality ratio and low operational costs. Every component is made of stainless steel or high-grade plastic material which is highly resistant to most corrosive media. This combined with easy access and maintainability of vital parts guarantees reliable operation and a very long lifespan product that will last decades.

AURA PRESS, the latest breakthrough in DEWA’s esteemed belt press portfolio, introduces a host of compelling features tailored to meet your unique needs. With its remarkable high flow capacity, exceptional load handling capabilities, and consistently outstanding performance, AURA PRESS is engineered to exceed your expectations.

The DEWA P-C “Mini” sludge dewatering unit is ideal for small-scale sludge dewatering applications. This compact twin belt design has a small gravity thickening zone followed by a wedge and pressing zone. In process principle “Mini” imitates its big brothers, DEWA N-PD XL and FPD. In the performance “Mini” will reach the lower dewatering requirements and is particularly applicable for industrial sludge types. The “Mini” is available in three different sizes with standard belt widths of 0.7m, 1.1m, and 1.6m. The best possible materials, the stainless steel frame and rollers make it robust, reliable, and long-lasting. “Mini” is the most economical choice for applications with low throughput requirements.
