A biogas plant provides an efficient, economical and sustainable method of generating energy. A particularly important aspect of the biogas plant is the digester feeding; this is decisive for the gas yield. But how does solid matter feeding suitable for bacteria work? The potential of “liquid feeding” is a widely discussed method in this context.

Using a state-of-the-art Vogelsang solid matter feeder, it is possible to prepare and mix solids with a liquid component in a particularly advantageous way. This treatment enables you to increase your gas yield and reduce your energy costs. How does this work and what technology can help you? Let’s take a closer look!

Who would have thought that dentures, identity cards or beer bottles could be found in wastewater treatment plants? It is patently obvious that wastewater treatment plants are not designed for these materials. Another product that are a major challenge for wastewater treatment plants is wet wipes. In many cases, they have become an indispensable part of the household. Wet wipes are used for various purposes, such as cleaning a baby's bottom or special cleaning wipes for toilet or smooth surfaces. However, not every wipe is the same.

There is waste in almost every production area. This is also the case with the production of bread. In large bakeries and supermarkets there are tons of bread every day that have to be sorted out for various reasons. However, this waste contains many valuable raw materials and is far too good “for the bin.”

Heavy rain is overloading sewage systems and treatment plants more and more frequently. Storm tanks keep the drainage flowing smoothly.

Positive experience of cooperation ensures environmentally compatible and resourcesaving energy and materials. Unnoticed by most, one of the biggest biogas plants that converts waste into valuable resources, went into operation in 2019. 

The PierPump by Volgelsang disposes of wastewater from boats simply, cleanly and reliably. It helps to obey the new environmental regulations. With the PierPump, disposal of wastewater and bilge water is as straightforward as refueling at a filling station.

November 11, 1991 in the Rothenschirmbach industrial area: The starting signal has been given for the construction of the branch. Vogelsang has acquired the property for its second German site.

In an emergency, when flood waters have flooded streets, basements and apartments, mobile pump power is required. And rescue workers and helpers must be able to rely on it – one hundred percent. Time for Vogelsang pump power. Rotary lobe pumps from Essen (Oldenburg) shine with their high pumping capacity, compact size and many possible applications.
