DYNAMIC DRUM THICKENER WITH ARCHIMEDEAN SCREW

 

 

The state of the art in the thickening solutions for municipal and industrial sludge.

To solve the problem of sludge thickening, TEKNOFANGHI proposes SCRUDRAIN® dynamic thickeners with Archimedean screw inside. SCRUDRAIN® is placed before plate filter presses, belt filter presses, centrifuges and drying beds, to achieve higher dry solids concentrations before dewatering.  Our thickener is also used to increase the sludge concentration before biogas reactors or just as filters to remove coarse material such as fibres in the textile industries. The concentration of D.S. in the outlet from the sludge thickener can be achieved by changing the speed of the Archimedean screw (e.g.: sludge with 0.5 - 3% D.S. can be thickened to 5 - 15% D.S.).

TYPICAL APPLICATIONS:

  • Municipal wastewater

  • Industrial wastewater

  • Food and beverage,

  • Dairy farms and slaughterhouses

  • Wineries and breweries

  • DAF sludge

  • Chemical industry

  • Paper mill

  • Drinking water, river and lake water

  • Mineral, ceramic, glass

  • Ground water remidiation

  • Oil sludge

  • Biogas

HIGH CAPACITY

The achievable thickening results are much higher than with conventional systems. SCRUDRAIN sludge thickeners can handle from a few m³/h, to a maximum of 200 m³/h per single unit, depending on the type of sludge and the dry solids content.

ARCHIMEDEAN SCREW

The SCRUDRAIN® main advantage is an “Archimedean screw” inside instead of conventional empty drum thickener. As a general guide, sludge with 0.5-3% can be thickened to 5-15% dry solids (DS) depending on the sludge.

FILTRATE

The dirty particles, removed during the washing phase, remain inside the drum thickener and are discharged together with the thickened sludge, ensuring a particularly clean filtrate (high efficiency capture) up to > 98%.

AUTOMATIC WASHING SYSTEM

The filter cloth is kept clean with an automatic washing system, using special TEKNOFANGHI designed spray nozzles, which use less water than other standard nozzles on the market. For rapid cleaning of the nozzles, they can be easily removed and cleaned, without using any tools

LONG LIFE FILTER CLOTH

The filter cloth has a long life, since it is not under tensile stress because it is directly fixed on the screw. Combined with the robust and simple structure of the machine, these thickeners are extremely reliable.

PLUG AND PLAY UNITS

SCRUDRAIN® thickeners are supplied as “plug and play units”, complete with control panel, washing pump, and all ancillary equipment necessary for efficient operation. The control panel enables complete automatic operation of the machine, it is designed to be interfaced with other panels, and supplies signals to drive sludge and polyelectrolyte pump. The machine is completely enclosed, to prevents odour.

DEDICATED ACCESSORIES

As optional accessory, the SCRUDRAIN® can be equipped with a reactor-flocculator to optimise sludge and polyelectrolyte mixing and to distribute the sludge inside the drum thickeners optimally. Each SCRUDRAIN® model is available with a dedicated tank for thickened sludge storage and transfer which is complete with level probe and thickened sludge pump.
