The drum filter made by VDZ Aqua is specially designed and constructed for continuous business operations.


The self-cleaning sift-drum is fully made of stainless steel AISI 304. The cone-shaped sifting rings are mounted on the internal corrosive resistant carrying arms. 


Because of the inward-facing cone, it creates a profile that opens to the inside, this prevents clogging. Also, this causes a flush surface with a specific gap width, suitable for all types of wastewater. 


A dividing compartment with a landing in front of the drum guarantees an evenly distributed water distribution spread over the total width of the drum. A scraper knife is mounted over the total surface width of the rotating drum. The knife of the scraper removes solid materials that are situated on the surface of the drum.


The necessary pressure needed from the knife is caused by a spring or a weight.


The drive system for the rotating drum is a geared motor and a worm transmission with adjustable rpm’s. The hollow shaft simultaneously acts as a connection for the cleaning/spraying system.


In the drum filter, there are multiple sprayer heads that make sure that the drum is cleaned an extra time.


The wastewater flows from the inlet compartment onto the slowly turning drum. Solids that don’t go through the filter stay on the surface, and are removed by the scraper knife. The knife has been designed to bring the recently removed solids to get moved to the gutter and into a disposal bin.


The filtered liquid flows through the filter from the outside inwards. After that, the filtered wastewater flows from the inside back out for an extra cleaning effect.

Unique and highly efficient VDZ aeration system

Based on our experience and know-how we created an aeration system that is more reliable, uses fewer parts but also makes more white water than traditional systems.

Small footprint

Our innovations have led to more flexible designs which can be built to a smaller footprint compared to traditional systems.

Low cost of operation

Through optimization of all aspects of the system, our treatments use less power, chemicals, and maintenance compared to the traditional systems.

Our Story

VDZ group of companies is family-run and values cooperation and team effort.

The basis of VDZ Aqua lays in 1982 when Jan van Sinderen started at Pielkenrood and was later strongly involved in the founding of Nijhuis water technology. In 1995 his son Bas joined him in the industry.

So our solutions are based on 40 years of experience in the wastewater treatment industry in combination with the thorough process know-how of our clients.

Based on this also developed an advanced and more efficient new aeration system. This is implemented in our plants to build very efficient water treatments with ease of use and a low cost of operation.

Thanks to our sister company VDZ trading we have the ability to provide used equipment as well. In this case, we replace all critical components with new ones and implement the latest developments and technologies. This greatly reduces the ecological footprint of the installation while maintaining our high-quality standards.

Now at VDZ Aqua, we combine all of this know-how into comprehensive packages and solutions for our customers.
