Wilo-Sevio ACT

Series description

Your advantages

  • Gentle input of biomass carriers into the fluid
  • Efficient due to increased volume of penetration for an optimised treatment process
  • Reduced energy costs with improved treatment performance
  • Also available with energy-efficient IE3 motor technology
  • Retrofittable in existing systems

Construction

Solids diffuser

Application

Gentle process for mixing all kinds of biomass carrier particles in the pumped fluid

Equipment/function

The solids diffuser permanently sucks the biomass particles from the surface of the basin and channels them back to the lower layers of the fluid via the pipe. The angled outlet ensures the biomass particles do not drift up or down in an undefined manner, but remain in the fluid for a longer period, thereby supporting the biological process. This circuit ensures the biomass particles are only at the surface of the fluid for a limited time and that they remain active for the treatment process for a considerably longer period.

Description/construction

The solids diffuser consists of a pipe with angled outlet, a submersible motor and a propeller.

The pipe is used here for channelling and direct entry of particles into the fluid. The angle of the outlet can be adjusted vertically and horizontally according to the relevant conditions.

The motor is secured centrally in the pipe. A surface-cooled motor with IE0 or IE3 classification (in accordance with IEC 60034-30) is used here. The heat from the motor is transferred directly to the surrounding fluid via the motor housing. The winding is equipped with a temperature monitor. The power cable is a type NSSHÖU cable for heavy mechanical loads. The power cable enters the motor housing through a water pressure-tight cable inlet with strain relief and bend protection. The individual wires as well as the cable sheath are additionally sealed to keep out fluids.

The propeller is driven by the motor and features a specially optimised geometry for safe transport of the particles.
