Separation Technology

BAUER SEPARATORS

Strong output and optimum dry matter content are the characteristics of BAUER Separators. Their long durability lead back to many years of experience, perfect technical design and the use of high-quality material. This makes us the technological leader in this field.

Separator

Based on our quality assurance system ISO9001 and constant development of all our components, Bauer manufactures products of only the highest standards.

Separation saves money

Separation stands at the forefront of liquid manure management. It is the starting point of subsequent meaningful liquid manure preparation. After separating into solid and liquid media, many useful opportunities for further processing exist. For instance, the separated solid portion is used today to produce valuable bedding material or compost. The liquid manure in turn ensures reliable growth in the fields during every growing season. It replaces chemical fertilizer to save money, lowers environmental impact and promotes animal health.

Lower costs, better animal health – BAUER.

The BAUER SEPARATOR converts manure into a valuable fertilizer

Fully-automatic separation – that means splitting up slurry into a liquid and a solid fraction – offers great advantages.

The thin slurry remaining can be distributed any time without any sophisticated homogenizing techniques.

The odorless solid fraction is easy to store without any problems

Economical use of existing resources with up-to-date technologies.

Farms with high animal concentrations are faced with great problems due to the large amounts of manure. This applies particularly to farms with a high stock per unit and area. Existing legal requirements aggravate the situation. For this reason, slurry must be treated adequately. Customary manure management systems are time-consuming, labor-intensive and can require enormous investments as well.

High economic efficiency

Slurry separation is the ideal solution for farms with a large animal population and small distribution areas. It reduces the storage capacity requirement up to 30%. Through specific use of nutrients of the liquid and solid fractions, mineral fertilizers can be saved. Extra profits are possible by selling the solids to small gardeners for example, or as a basis of compost for horticultural farms.

Thickener Bridge with Central Drive

Posted on by
Thickener Bridge with Central Drive

DESCRIPTION AND WORKING PRINCIPLES

The thickener bridge with central drive can be installed in different sizes of reinforced concrete tanks. Its purpose is to thicken and prepare sludge from the decanters for subsequent treatment. The in-flow of sludge is diverted by the settling cylinder to optimize thickening; special pegs turn very slowly to expel any air still in the sludge. Bottom scrapers remove the accumulated sludge for collection in the central hopper, where it is extracted through pipes. The clarified water flows in the peripheral channel.

MANUFACTURING FEATURES

 

  • Torque shaft made of carbon steel suspended axially from the control unit.
  • It is provided with fittings for the central distributor and for hinging the scraping unit;
  • Double arm scraping unit made of carbon steel, on which are mounted the adjustable scraper blades and the thickener pegs;

Periferal Scraper Bridge

Posted on by
Periferal Scraper Bridge

DESCRIPTION AND WORKING PRINCIPLES

The bridge is installed on a circular basin with a tower and central scum box for removing the sludge. It is used in those cases where suspended particles in sewage need to be separated and removed by gravity.

The water and sludge mixture from the central tower is diverted by a baffle cylinder to let the sediment solids settle at the bottom. Scraper blades convey the precipitated sludge to the central cone in the tank where they are then extracted with a pump. The clarified water flows in the channel around the top perimeter of the tank. Any floating materials are trapped by a blade in the spillway and taken to a collection and discharge tub.

MANUFACTURING FEATURES

LONGITUDINAL SCRAPER BRIDGE – DEOILER/CLARIFIER 01
Longitudinal Scraper Bridge 3
LONGITUDINAL SCRAPER BRIDGE – DEOILER/CLARIFIER 02
Longitudinal Scraper Bridge 2
DESCRIPTION AND WORKING PRINCIPLES

This unit can be installed in a rectangular basin for removing particles of sediments and floating material in sewage. The sewage inlet is in one of the short sides of the tank. Air passes through porous ceramic filters in the tank encouraging the sediment substances to settle. The bottom scraper turns in the opposite direction to that of the sewage inlet to move the sand into a scum box. The forward limit switch signals the movement control unit to reverse direction and, at the same time, the scraping blade lifts up from the bottom while the surface scum blade moves down and conveys the oil to the skimmer. The return limit switch restores the previous condition. The water is in this way cleaned of most of the suspended solids in the channel.

MANUFACTURING FEATURES

  • Bridge deck with accidental overload 250 kg/sqm
  • Max deflection 1/500 of the span, made of carbon steel and with galvanized screen walkway, tubular railing with handrail and footguard, in conformity with safety standards, and entirely made of carbon steel;

Side Channel Blowers

Posted on by

Side Channel Blowers

The side channel blower or exhauster increases the pressure of the aspirated gas by the creation, in the peripheral toroidal channel, of a series of vortexes caused by the centrifugal thrust of the impeller. While the impeller is rotating, the vanes force the gas forward and, because of the centrifugal thrust, outwards, producing a helical motion. During this motion, the gas is recompressed repeatedly with a consequent linear pressure increase along the length of the channel.

Applications and advantages
Side channel blowers are suitable for all those applications requiring considerably higher pressures than that which can be achieved using centrifugal fans. Side channel exhausters are used in all those applications requiring an operating vacuum higher than the one achievable by a fan, but not as high as to require the use of a vacuum pump. The rotating parts are not in contact with the casing. There is therefore no friction during operation and thus no internal lubrication is necessary. The gas moving through the machine therefore remains uncontaminated and completely oil-free. The other main advantages of using side channel machines are: easy installation;
low noise level;
no vibration and therefore complete dynamic stability;
pulsation free discharge;
minimal maintenance.
