A plug and play solution
The Rotary Drum Sieve combined with a Buffer Tank Platform is ideal for projects that require continuous inline straining of coarse pollution from flows up to 150 m³/h. Applications include straining of large solids from flows transferred by vacuum trucks to protect equipment such as United Rentals pumps, and washing and straining of course particles.
Challenges
Cleaning of sewer, pits or basins involves many challenges due to various large pollutants. Large Petro-Chemical Residues, Wipes, Stones, Plastic and Organic Materials can obstruct or damage treatment equipment during processing. This is especially prominent with high volume flow where static strainers are insufficient and invariably prone to blockage. This costs time and money.
Special for this challenges we added the Rotary Drum Sieve at our product catalogues. With the Rotary Drum Sieve, also called RDS, we provides the complete solution. When you add the RDS at the beginning of the process, you will capture the big pollutants, prevents damages and ensures a continuous and fast flow of your liquid. An ideal solution for high volume flow with no human intervention is required.
Working principle
Transferring liquids into the Rotary Drum Sieve can be processed by a vacuum truck or pump. Within the drum there is a 3 mm perforated sieve which captures the large pollutants. Due to the rotation movement the waste is ejected from the sieve negating the coagulation of materials and preventing blockages.
Additionally a safely concealed Auto-Cleaning system has been integrated into the drum. Waste materials are loosened from the nozzle in conjunction with high pressure water jetting and the rotational drum movement.
Through the ‘diagonal orientation’ gravity discharges the waste material. A flexible plastic hopper guides the waste and solids to the dewatering box. The clean liquid is collected in the buffer underneath the drum.

Case study: Cleaning a canal following a landslide. Solution for efficient debris removal.
Challenge:
Cleaning up debris from a canal following a landslide is no easy task. It requires a combination of manual labour and high-powered equipment to remove the large debris and clean up the rest. One recent project in France used the Rotary Drum Sieve: it was efficient, cost-effective, and easy to use.
Solution:
The first step was to manually remove the larger debris from the canal. Once this was complete, the team used a pump to clean up the rest of the debris. The pump was able to remove about 10 m³ of coarse solids, including earth, gravel, stones, and bitumen, with a large volume of water at a flow rate of up to 140 m³/h. This process helped to optimise treatment costs by minimising the amount of material that needed to be destroyed.
However, the client required that the solids be filtered down to 3 mm before the water could be discharged into a nearby pond. To meet this requirement, the team used a self-cleaning screen that was easy to install and use with an automatic transfer of solids >3 mm to a waste bin. This solution not only filtered the solids down to the required size but also provided a high treatment rate for a small footprint space requirement.
Benefit:
Using the Rotary Drum Sieve allowed the team to clean up the canal efficiently and effectively, without incurring high costs or damaging the environment. The easy installation and use of the self-cleaning screen also made the process smoother and more straightforward, allowing for the automatic transfer of solids and reducing the need for manual labour.
