The BRU concept developed by FAN Separator GmbH., a Bauer Group company, has been put into practice since 2005, and many installations are operating successfully to the highest satisfaction of their owners all over the world. A heavy dairy cow needs to be bedded well. The choice of the appropriate bedding material is therefore not to be taken lightly. All materials have their advantages and disadvantages: Straw involves an unknown level of germ contamination and high storage costs. Sand is not very absorbent and causes heavy wear to machinery resulting in high expenses. Wood chips are rather expensive and not always available. All of these materials must also be transported to the farm first and then disposed of afterwards involving further expenses. Those who can afford them, still opt for the use of mattresses with the usual problems. BRU bedding material combines all advantages. BRU bedding is low-priced, fresh and available every day, highly absorbent, of a perfectly hygienic, constant quality and it is readily accepted by the cows. It is worth taking a closer look at the BRU concept: The BRU is synonymous with recycling and producing fresh bedding material every day, directly on the farm. There is no need for additional storage space or reductions to the amount of solid matter in the slurry or overall slurry volume. The slurry is first pumped from the collecting basin into the FAN press screw separator where the undigested fibres are separated from the raw manure. Then the material is fed into and transported through a 3 to 10 Meter long stainless steel drum (depending on the model) by means of a special patented conveying system. It takes the material anywhere from 8 to 22 hours to pass through the drum. During this time, micro-organisms are acting on the material. Without any additional external energy, and through a natural, aerobic process, temperatures inside the stainless steel drum rise to more than 60°C to 75°C so that the material is not only dryer but also becomes hygienically perfect. The biological hygienisation process is a type of fast composting. At temperatures of 60°C to 75°C inside the drum, almost 100 percent of all pathogenic germs which cause mastitis in dairy cows are destroyed. The inflammation of the udder involves huge economic damage to milk farmers again and again. Fresh, bio bedding material is one of the many prerequisites for high milk output. The biological process inside the drum is monitored and controlled by means of temperature metering and the airflow rate. At the BRUs outlet, the material has a dry matter content of 40 to 42%. By means of conveying equipment, the bedding material is transported into an intermediate stock – 10 to 48 m³ of bedding material can be produced per day. With this amount of bedding material from 300 to 2.000 cows can comfortably be supplied.

The BAUER Rainstar is the best solution for famers searching a cost and energy saving irrigation system with with the highest level of performance and operating reliability. In addition to that the Bauer Rainstar is easy to use and offers an excellent quality and attractive price-performance ratio. From a wide range of machines the exactly right model can be selected for every field shape and size. The radial full flow turbine, developed by Bauer after intensive research, assures a cost and energy saving irrigation and is particularly efficient when low precipitation rates are applied. With the newly developed GPS-assisted application “SmartRain” for smartphones and tablets Bauer offers a modern solution for managing and optimizing irrigation systems. Specific operating states can therefore be activated via the app as well as starting, stopping and changing the retraction speed (or irrigation amount). A settings menu allows even more functions used on a daily basis to be easily modified in the app or from a PC with web browser.

The innovative solution for sludge separation promises not only more hygiene but also operating costs- and time-saving. The sludge press SPS 8 - 1200 is used in municipal sewage plants and wherever industrial sludge needs to be dewatered as for example in meatpacking, milk and tannery industry. The FAN sludge separator SPS 8 - 1200 has a drive power of 0,55 KW, the solid matter can achieve a dry mass content of up to 30 %. The sludge separator is used in municipal sewage plants where decanter centrifuges often have been used so far. The aim of the new system is always separating liquid from sludges and so to change their content of humidity, volume and consistency. For example the more sewage sludge is going to get dewatered the cheaper are the disposal and transportation costs. Advantages compared to decanter centrifuges The essential advantages compared to other dewatering technologies are the considerably lower energy and maintenance costs and higher dry mass contents. The mostly high operating costs can be considerably reduced with the sludge press separator. Another distinctive feature is the screw of special geometry designed for sludge dewatering. A highlight of the SPS 8-1200 is the auger made of low-wear high-performance plastic which has a special geometry for dewatering sludge with 0,5-10% dry matter content. Moreover, the FAN sludge separator is the only screw press on the market which does not need wipers or brushes in order to screen the inside of the screen.

The separators from BAUER, used in agriculture and industry such as pharmaceutical and food industries, enable the fully automatic separation of waste substrate into liquid and solid phases. This is made possible by the significant reduction in the waste volume (15-30%). In addition, the liquid phase can be more easily distributed on the field or further treated in treatment plants, for example. The use of the solid phase as fertilizer or as a basis for compost is also a possibility. BAUER offers a wide product range in this area: S300: An economical solution for wastewater treatment for small operations For small companies, BAUER offers the small separator S300: The newest model of the product family weighs only 220 kg with a footprint of 1.3 x 0.5 m and a height of less than 90 cm, making it more than suited for its role as a compact unit. Despite these small dimensions, the S300 can deliver throughput of up to 16 m³ per hour. S655/S855: Numerous potential uses – including in industrial applications For users with moderate to high waste volumes, BAUER offers the separators S655 and S855. These machines separate 10 to 25 m³ (S655) or 15 to 35 m³ (S855) of substrate per hour and guarantee energy-efficient separation of the organic fertilizer. The throughput varies depending on the age, dry matter content and consistency of the waste. The liquid phase (70-85%) is optimally suited for spreading with pipe and hose systems. The solid phase (15-30%) – self-composting, odorless, stackable and therefore easy to store – can be sold as fertilizer or compost, for example. S855 GB: “Green Bedding” separator for recognized bedding quality The use of separators for processing slurry into bedding for dairy cattle is growing increasingly common. With the help of the “Green Bedding” model, the moisture level, volume and consistency of the starting material are changed to produce high-quality yet inexpensive organic bedding. A high dry matter content in the solid phase is critical for hassle-free use as bedding. The BAUER S855 GB ensures a constant DM content of up to 36% – a level that has been shown not to increase the risk of mastitis. In contrast to previously used bedding materials such as straw, sawdust, rubber mats or sand, the “Green Bedding” variant does not generate high costs either for procurement or disposal. The resulting bedding is also optimally accepted by the animals and offers a high level of comfort. Both criteria have a significant impact on the milk output. “Plug & Play”: Efficient and mobile separators All separators are also available in mobile designs: The “Plug & Play” separator systems from BAUER are compact units in which all components from the intake pump to the electronic control are packed into the smallest possible space: Once connected to a power socket, these compact space-savers immediately and efficiently separate the solid from the liquid phase. The complete systems are each driven by BAUER HelixDrive pumps.
