1 Automatic fine rotation screen

EKOflow FIN 1

Automatic fine rotation screen
Basic measures:
QMAX MAXIMUM CHANNEL FLOW 2400 L/s
DMAX MAXIMUM DRUM DIAMETER 2,8 m
WMAX MAXIMUM CHANNEL WIDTH 3,0 m
HMAX MAXIMUM CHANNEL HEIGHT 3,0 m
S LIGHT SPAN BETWEEN DRUM BARS 1 - 6 mm
Application:
  • For mechanical pretreatment of wastewater/rainfall water, removes all particles larger than the chosen plates on the drum.
  • Device is multifunctional: collects, transports and drains water form the collected waste in the pressing zone.
Working principle:
  • On the internal side of the rotating drum waste water flow brings bulk waste which remains on the drum plates, on its internal side. By rotating, the drum lifts the waste on its upper side.
  • On the upper side, just behind the drum, there is a spray lath with nozzles. Spray lath is connected to clean water supply using electromagnetic valve. Water flow from nozzles takes off the collected waste material and throws it towards the drum center into the open basin placed on the lower part of the spiral.
  • Spiral transports water to the pressing-draining zone, where, after the water is separated, waste is being removed from the device, usually discharged to the municipal container for solid waste.
  • Clean water is using electromagnetic valve introduced into the pressing zione and it rinses the sludge made by pressing the material. Rinsed sludge is drained with a pipe and returned back to the inlet of the device.

2 Automatic fine screw sieve

Automatic fine screw sieve
Basic measures:
QMAX MAXIMUM CHANNEL FLOW 150 L/s
WMAX MAXIMUM CHANNEL WIDTH 0,9 m
HMAX MAXIMUM CHANNEL HEIGHT 2,0 m
S TROUGHT-SIEVE PERFORATION SIZE 3 - 6 mm
Application:
  • For mechanical pretreatment of wastewater/rainfall water, removes all particles larger than chosen perforation (clear width between plates) basin-sieve device.
Options:
  • Depending on the installation angle, we can differentiate:
    - Aslope construction – usual installation angle 30-40°
    - Vertical construction – installation angle 90°
Working principle:
  • Waste water flow brings waste material onto the sieve. Material remains on the sieve if its size is larger then the clear width of the sieve. Spiral rotation transports waste upwards to the draining-pressing zone where, after water is separated, it is being discharged from the device, usually to the municipal container for solid waste.
  • Clean water that rinses the sludge made when material is being pressed is brought to the pressing zone. Rinsed sludge is drained back into the channel through a drain pipe. Clean water is through the nozzles also used to wash out the lower part of the spiral with sieve in the channel.
