NETZSCH is known globally as a specialist in the areas of wastewater treatment and biogas technology. Rotating positive-displacement pumps have been used for decades in these markets, and NETZSCH offers a wide variety of applicable pump systems. Among the selection of NEMO® progressing cavity pumps, TORNADO® rotary lobe pumps and our grinding systems, we are sure to have the right pump solution for you.
Beets, particularly sugar beets and specially-bred energy beets, are becoming more and more popular. The storage of the beets in silos or silage tubes is complicated and expensive. Collecting beet pulp in foil-lined reservoirs represents a comparatively simple and cost-effective alternative to this. More
Used service water from industrial processes is one of the most problematic types of waste water due to its composition, which is often very demanding for conveying systems. In order to enable problem-free treatment of this kind of waste water in spite of this, the T.Envi® is specially designed for a long service life with minimum wear, so that it can also convey extremely abrasive media without any problem.

In order to be economically viable, biogas plants today must be able to be operated using a variety of energy crops and bio waste. However, changing sources can rapidly become a problem for the operating company: The consistency and composition of the biomass is difficult to predict due to natural fluctuations in their origin, coarse material continues to block lines and pumps.

wo things are severely limited on ships: space and time. Compactness is particularly vital in the machine room, as each centimetre means a loss at the expense of valuable transport capacity. At the same time, the systems have to be robust, as manpower can hardly be switched to repairs at sea and interim port stops are to be avoided at all costs for reasons of time. So maximum demands are placed on safety-critical systems such as bilge pumps. More
There are two aspects of wastewater treatment plants at Celle (Germany) which have a direct use: in addition to cleaning waste water, the sewage sludge which arises with the nutrients it contains can be used later as manure in agriculture. The sewage sludge is transported via a pressure pipe around 25 metres in length with several right-angled turns – ten metres of it being geodesic – to a silo and from there it is later spread over agricultural areas. So that the mix can be stored, it is first dewatered in an angle press and flocculating agents are added. More
When pumps are used on ships and in ports, the technology must meet special requirements: this means the pumps should not only cope with a really wide variety of fluids, such as wastewater and lubricant oil, but should also be as space-saving, maintenance-free and easy to handle as possible.

While Germany still faces many unsolved problems in terms of implementing the energy turnaround, they have moved significantly further on in South America. Of all the countries, the developing nation of Brazil is proving itself to be the role model when it comes to renewable energies. Around 75 percent of the electricity requirement is covered by hydroelectric power there. More
Cutting systems, which are based on high-pressure water jets and do not alter the material structure through their energy input like lasers do, are establishing themselves in more and more areas, such as robotics or automotive manufacturing. A cutting aid, an abrasive, is mixed into the water to increase cutting performance. This abrasive is frequently a fine garnet sand. After the cutting process, the water-sand mixture has to be separated again, so that the sand can be disposed of. A manufacturer of water jet cutting systems offers an automated solution for its systems to remove and separate the sludge from the water. More...
