Installation and Maintenance Recommendations Services

0

General for All Regeneration Equipment, Treatment Units and Pre-Treatment Equipment. For the proper operation of the treatment unit, rainwater should previously be separated so that it does not enter the treatment system. The water intake pipe to the treatment unit should be diverted into two for the installation of a gas exhaust pipe. It should not be left at the level of windows, terraces or other normally frequented places. Avoid the use of elbows as much as possible. The gas exhaust pipe diameter should be the same as the water intake pipe. Equipment access traps, together with the sample-taking trap, should be properly closed and accessible for control and maintenance. The electrical connections should only be carried out by a qualified electrician. It is essential that the unit be correctly levelled.

  • Never start up the blower / turbine if the treatment unit is not full. The diffusers could be irreversibly damaged.
  • This equipment should be installed on a flat surface as close as possible to the treatment unit. In addition, it should be installed in a place protected from excess dust and cold air. It is recommended to install in a well-ventilated purpose-built shed. It is important for blowers to be at least one meter from the wall for good heat dissipation.

  • Separators should only be installed in drainage systems in which it is necessary to separate light liquids from the water and retain them within the separator. These devices should not be installed in drainage and sewerage systems containing domestic wastewater.
  • Separator systems should be installed near the source of the light liquid, in well-ventilated areas that are easily accessed for cleaning and maintenance.
  • A ventilation pipe should be installed in the outlet pipe. The ventilation pipe should always allow air to pass through, which is why the factory-fitted stopper should be removed and the pipe extended to the outside.
  • Before putting the separators into service with the sealing system, the float should be removed from the sealing system.
  • Once the equipment is filled with water, replace the float.

Roxplus

  • Emptying of water and sludge twice a year.
  • It is recommended to clean the turbines’ suction filters every 6 months.
  • Clean the membranes with sodium hypochlorite (commercial bleach).
  • Use the membrane-cleaning opportunity to empty the sludge from the biological reactor and then empty out half of the membrane compartment.

Grem

  • Review the filter status every fortnight.
  • It is recommended to clean the suction filters of the blowers every 6 months.
  • It is recommended to empty sludge once or twice a year.
  • Clean the membranes with a sodium hypochlorite (commercial bleach) solution.
  • Chlorination system: Periodically fill up the hypochlorite tank. The filter should be cleaned once a year.

NECOR

Decanter: Sludge should be emptied every 1-2 years or when the sludge level height reaches 50% of the decanter’s useful volume.
Reactor and run-down screen: Sludge should be removed at the same time as it is removed from decanter. For removing sludge from the reactor, a hose should be used to carefully spray through the pipe installed in the wall that separates the reactor from the run-down screen to prevent the extraction of the plastic filler.

Sludge removal should be performed by companies authorized to do so. This operation is performed with a tanker truck.

  • Membrane blower: The suction filter should be regularly cleaned. To do this, remove the compressor lid, remove the filter, clean it with compressed air, replace it and close the lid.
  • Electrical panel and sludge recirculating pump: Maintenance-free.

SBREM

Decanter: Sludge extraction by means of a tanker truck every 6-12 months.
Reactor: Sludge extraction by means of a tanker truck: It is recommended to empty 4/5ths of the equipment every 6-12 months, preferably during the months of April and October. (Avoid the warmest or coldest months).

  • Turbine: Check the suction filter on a monthly basis and if dirty clean it with compressed air. To remove the suction filter, the turbine has to be stopped, the mushroom-shaped head at suction point dismantled and the filter removed.
  • Electrical panel and decanter and reactor pump: Maintenance-free.

Oxidation Unit (ROX)

Emptying of sludge twice a year. It is advisable to leave a fifth of the volume for the regeneration of the biological culture and refill with clean water. On some occasions maintenance can be performed over shorter periods (quarterly or six-monthly). It is necessary to perform regular controls of floating sludge and eliminate any excess sludge and to check the status of the Thompson dump at the outlet of the treatment unit and remove any excess sludge that may have built up.

  • Blower: Models: ROX 5 to ROX 50: it is necessary to change the membrane approximately every 2 years. Models higher than ROX 50: it is necessary to regularly clean the suction filter of the turbine.
  • Electrical panel and sludge recirculating pump: Maintenance-free.
