Module type WWTP for 50 to 1200 PE

The module type Wastewater Treatment Plants (WWTP) offered by AQUARIUS ND Ltd. are based on the extended aeration purification process.

Generally, the moduletypeWWTPconsistsof:

Inlettank – made of concrete or metal, which is located out of the module.

Serves for receiving the wastewater and equalization of the wastewater flow and content.
At the inlet of the tank is installed screen made of stainless steel, cleaned manually and submersible feeding pump.

Module type WWTP състоящ се от:

  • Biological tank
  • Secondary settling tank 
  • Disinfection tank
  • Tank for sludge stabilization
  • Machineroom
  • Blower– 1 pcs.
  • Tank for sodium hypochlorite– 1 pcs.
  • Dosing pump– 1 pcs.
  • Feeding pump– 1 pcs.
  • Electrical board– 1 pcs.

Note: If the terrain allows, the wastewater can go directly to the module WWTP trough inlet pipe at 30 cm. above the elevation of the upper edge of the module. In this case the receiving tank will not be obligatory and the screen is mounted in the module, below the inlet pipe.

The module is installed on a concrete foundation.
