ROTAMAT® Disc Thickener RoS 2S – A perfect reference of reliability

For more than 10 years the ROTAMAT® Disc Thickener RoS 2S has been a permanent product of the HUBER range for mechanical sludge treatment. Sales have increased year by year and prove the success of our patented thickener. Especially the continuously increasing international demand for our Disc Thickener led to a soft redesign of the whole construction in 2008. One of the goals of that redesign was to increase operating reliability and reduce maintenance requirements.

Due to its innovative design the Disc Thickener has never needed any lubrication points or high-maintenance ball bearings. Also its extremely wear resistant stainless steel filter has always been guarantor of a long product life. ®  

The following three installation examples give proof of the inspection interval of 15,000 to 20,0000 operating hours we often see in practice. The typical operational performance per operating hour is 0.7 to 1.7 km on the screen circumference.

RoS 2S at WWTP Meldorf
RoS 2S at WWTP Meldorf

Up to now, the RoS 2S unit installed on WWTP Meldorf (Germany) is leading in running without any replacement of wear parts.

Start-up date:  June 2004
Sludge type:  excess sludge
Throughput:  5 m³/h; RoS 2S 1
Operating hours:  53 650
Operational performance:  approx. 38 000 km
Demand for wear parts:  /

Almost unbelievable 50,000 running hours without replacement of wear parts have been achieved even under quite difficult conditions. The unit is an outdoor installation without special protection and has been operated virtually without any interruption for six and a half years.

The low demand for wear parts gives proof of reliability and safety but also of other, clearly measurable advantages, such as low operating and repair costs.
