MSE Hiller Ltd, Mobile and Separation Equipment (M&SE) specialise in the rental and sales of dewatering centrifuges into environmental applications within the water treatment and process industries. Effluents and sludges may be dewatered or thickened by use of either fixed or temporary installed mobile dewatering plants. Trial units are available for on site testing of applications and unit capacities range from 1 to 105 m3 per hour. The MSE Hiller range of decanter type centrifuges offer high performance sludge dewatering and thickening and there are over 5,600 units installed Worldwide. The centrifuges can be supplied with either hydraulic or electrical regenerative back drive capability for automatically adjusting the scroll speed to suit the solids loading of the feed. The hire service is available with or without process operatives and can be used for on site lagoon and pond clearances, digestor cleaning, seasonal peak loads/breakdown coverage etc. Mitsubishi rayon membrane systems can be offered for high efficiency separation and cleaning of effluents offering water re-use options to customers.

Hiller Decapress Centrifuge for Optimal Dewatering Results at Waste Water Treatment Plant in Switzerland

ARA Schönau is one of the largest and most modern waste water treatment plants in Switzerland.

About 20 million m3 of waste water are treated and cleared there annually by means of very modern processes. The state of art sludge treatment process used at site includes the Anammox procedure: by an anaerobic ammonia oxidation the nitrogen containing centrate from the sludge dewatering is pre-treated biologically.

For the new sludge dewatering technique the decision making criteria was based on:-

Cost-efficiency of the decanter centrifuges


Customer satisfaction of previously installed plants.

The Hiller Decapress dewatering technique succeeded in winning due to cost-efficiency combined with high performance

Hiller GmbH were awarded the contract following and open invitation to tender process due to excellent process results during trials, economic viability of the decanter centrifuges as well as the proven customer satisfaction on previously installed Hiller plants.

In December 2015 Hiller delivered two of their high-performance DecaPress centrifuges, type DecaPress DP574.

Since that time the new dewatering machines have brought optimal results in regards to waste water separation. Hiller was able to meet all the delivery deadlines and even exceeded the required process performance guarantees.

Innovation in regards to centrate regulation leads to stable operation process as well as reduction of polymer amounts.

An additional positive effect on cost-efficiency was the installation of the patented Hiller Centrate Control Camera. This is a newly developed system which ensures a continuous optical monitoring of a pre-selected centrate quality. This automatically regulates the polymer consumption in order to achieve optimal results and save polymer consumption.

By means of this innovative system it is no longer necessary to operate the plant with higher amounts of polymer at weekends or holidays because of safety reasons. Learn more about Hiller Centrate Control under: http://www.hillerzentri.de/images/hiller-centrate-control-en.pdf
