The new Hidrostal motors are available with drive power from 5 - 170 kW and are suitable for vertical and horizontal installation. Thanks to the design with protection class IP68, the motor pumps can be used in permanent flooded operation, but also in dry installation. The cooling is ensured by an internal energy-efficient cooling circuit. These characteristics make Tuma motors the ideal drive for screw centrifugal pumps to pump unscreened waste water, sludge or other demanding media. In addition to different speeds and voltages various insulation classes and combinations of construction materials are available. Various protection and monitoring elements ensure maximum safety and reliability

High efficiency aerator Spaans Babcock developed the third generation aerator: After a long period of testing, the ideal design was developed. A complete new design which ensures a high efficiency, a huge mixing effect and a very smooth running with less vibration to the bridge and drive unit. The new O2Max is designed on the basis of the latest know-how (knowledge) on surface aeration and beats the old problems with this kind of aerators.

The compact and highly sensitive fluorometers have excellent turbidity rejection and high ambient light rejection, making them suitable for use in water and wastewater treatment works, as well as natural waters at the surface and to depths of up to 1000 m.

General process concept: To achieve an ideal consistency in the raw or mixed sludge prior to the digestion, as a general rule the excess sludge is mechanically thickened before mixing with the primary sludge. The excess sludge thickening reduces the amount of sludge fed to the digestion tank. This yields considerable energy savings and better use of the digestion system, as well as longer retention times in the digestion process. This results in further reduced digested sludge quantities as well as improved dewatering properties thereof. Decanters for thickening are not designed according to the classical counter current principle, but according to the direct current principle. Thanks to this design, the suspension passes through the entire length of the centrifugal chamber in the direction of the discharge. The centrate water runs through channels in the direction of the weir openings. The result is a very long clarification section and thus minimal or no polymer as well as achieving the highest separation efficiencies. Hiller Lysate technology: The HILLER lysate device is attached in the area of the sludge discharge openings and uses the existing kinetic bowl energy. The disintegration effects in the thickened waste activated sludge (WAS) are mainly caused by impact and shear forces generated by the knife blades rotating at high circumferential velocity in the labyrinth and the lysing chamber. The WAS disintegration is carried out in the full flow of the thick sludge that has entered the lysate device; no lysate enters the separated centrate water. Advantages: - Viscosity reduction and better pumping properties at high thickening degrees - Cell disruption increase resulting in an increased degradation of the organic share - Gas yield increase - Improved dewatering behavior

The newly developed DecaSmart compact system series is ready for use immediately for your separation task. HILLER compact units for dewatering, can be put to work on your separation task straight away. In order to be able to offer an optimal solution for different throughput volumes, a DecaSmart of the decanter size DP31 is offered in addition to the current HILLER DecaSmart DP45N. The most significant advantages of the new, compact decanter series, among others, the quick availability for the operator, the simple plug and play integration into the running operation, as well as the attractive price with low operating costs. All process-relevant units are optimally matched to each other and are controlled and monitored via the integrated, user-friendly HILLER switchgear.
