ROXPLUS: regeneration station for wastewater treatment

ROXPLUS

Wastewater reclamation plant

The ROXPLUS regeneration station is a set of systems for wastewater treatment similar to a domestic system, from which quality water is obtained for reuse by means of membrane technology

The system complies with the requirements of Royal Decree 1620/2007, dated 7th December, whereby the legal system is established for reusing treated waters. These items of equipment are manufactured in compliance with the standards of BS-4994:1987 (British Standard Specification for Design and Construction of vessels and tanks in reinforced plastics) and Spanish Standard UNE-EN 976.

ADVANTAGES:

  • Compact equipment. Oxidation, filtering via membranes and recirculation in one single item of equipment.
  • Saving network water.
  • No need for decanter.
  • High effluent quality.
  • Small implementation surface area.

HOW A REGENERATION STATION SYSTEM FOR WASTEWATER TREATMENT WORKS

THE SYSTEM IS CARRIED OUT IN THE FOLLOWING STEPS:

  • BIOLOGICAL OXIDATION:

    The biological decomposition of the organic mat- ter takes place in the biological reactor thanks to the provision of air and the generation of aerobic microorganisms. Unlike the case with conventional total oxidation, higher concentrations of solids are worked with in the reactor, in such a way that more oxygenation is required and as the sludge is older, higher purification performances are obtained.

  • FILTERING:

    Filtering by membrane technology is used to bring about separation of the solid-liquid, the solids and bacteria being left on the outer wall. A suction system is used to exert a vacuum pressure on the membranes creating an inflow-outflow in such a way that the water seeps through the membranes, leaving the solids, viruses and bacteria retained in the outer wall.
    The sprinklers create an ascending airflow that makes it possible to clean the surface of the ou- ter wall of the membranes and guarantee aerobic conditions.

  • RECIRCULATION:

    Returning sludge to the reactor, to make the concen- trations in the two reactors equal.

  • CHLORINATION (OPTIONAL):

    The treated water is chlorinated with a dosage of sodium hypochlorite, ma- king it possible to conserve the sanitary properties of the effluent guaran- teeing the reuse of the
