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;
  • Replaceable scraper plates made of neoprene rubber.
  • Cylindrical central baffle made of carbon steel;
  • Peripheral spillway with Thompson profile made of stainless steel, with fixing and adjustment accessories;
  • Direct control unit consisting of an electric motor and epicycloidal step-down gear, with alloy steel oil bath gears with cylindrical and helical teeth, and suitable protection for outdoor use;
  • Central power supply at the top.

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

Bridge deck with accidental overload 250 kg/sqm, max deflection 1/500 of the span, resting on a steel rotating support at the centre and, at the side, on a trolley with rubber wheels; Central support with thrust bearing, lubricated with grease and mounted on a fixing plate, and horizontal pins for attaching and supporting the mobile bridge deck; Central baffle and settling cylinder made of galvanized steel, anchored to the central plate with threaded rods; Peripheral double-axis drive trolley made of carbon steel, with polyurethane coated iron wheels, shafts and wheel holders and supports; Bottom scraper arm consisting of a set of vertical tubular supports attached to the mobile bridge deck; hinged at the ends of the supports are profiles on which are attached a logarithmic spiral blade and the travelling wheels. The height of the blade can be adjusted according to the gradient of the bottom; Replaceable scraper plates made of acidresistant neoprene rubber. Distribution manifold of loop design, with brush holder, brushes and terminals for connection to the geared motor (consisting of a central rotary manifold with plastic protective base and rainproof Cover); Geared motor connected directly to one of the wheels of the trolley; Surface scraper, Thompson profile, collection and discharge tank of the scum box with supporting brackets.

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;
  • Trolleys made of carbon steel profiles, with polyurethane coated iron wheels of which two are geared and two are idler;
  • Anti-slip wheels coupled in the sliding profile;
  • Double blade made of steel tubes for collecting scum on the surface;
  • Bottom scrapers consisting of blades supported by nylon travelling wheels. The scraper is connected to the bridge by means of steel tubes with adjustable joints;
  • Replaceable scraper plates made of neoprene rubber;
  • Microbubble diffuser tubes made of selected silica sand and epoxy binder;
  • Bridge moving unit with worm geared motor directly connected to the driving gears;
  • Control unit for lifting the bottom scrapers and the skimming blade, consisting of a worm geared motor or, on request, a control unit and oil hydraulic piston;
  • Scum-box for collecting the scum, in stainless steel;
  • Limit switch.
  • Bridge deck made of hot-galvanized carbon steel;
