Reuse your wastewater for agricultural irrigation with REUSE reactors

REUSE reactors are suitable for the latest European requirements for agricultural irrigation. These compact sterilizers, specially adapted to REUSE quality classes A to D, are simply connected to the outlet of the wastewater treatment plant. They provide the necessary UV dose to guarantee the requirements on the E.coli parameters.

Here are some benefits of REUSE reactors:

  • Horizontal or vertical installation
  • Automatic lamp cleaning
  • Upstream and downstream sampling
  • 5 year warranty.

REUSE Reactor UV range

The REUSE range includes 4 sterilizers: S, M, L and XL. For each reactor, the maximum throughput was calculated for each quality class using highly constrained water, namely:

  • TSS = 35 mg/L
  • Transmittance = 50%
  • E.coli concentration: 100 000 UFC/100ml

Of course, if your wastewater leaving the WWTP is of better quality, the same reactor will be able to handle more flow, or you can choose the lower model.

Where to establish the REUSE reactors?

REUSE reactors should be installed at the outlet of the treatment plant, after the tertiary treatment, in order to ensure that the water to be treated meets the treatment requirements imposed on the treatment plant for the TSS, BOD5 and COD parameters.

Why choose this equipment?

This range of reactors has been specially designed for the reutilization of water at the plant outlet. For this reason, these devices were designed with the following applications in mind:

  • Automatic online cleaning system to reduce the formation of organic and inorganic deposits on quartz sleeves.
  • Upstream and downstream sampling valves to facilitate sampling during regulatory controls
  • Teflon UV sensor: to continuously monitor the UVC radiation of the sterilizer
  • Chemical cleaning quilting: to facilitate maintenance and increase radiation performance
  • Interface with detailed view:
    • UVC radiation in %,
    • System time counter,
    • System boot counter,
    • System states
  • Various voltage-free contacts to complete the supervision
    • General defect
    • Pre-alarm / alarm: Lamp efficiency decrease warning (i.e. UV intensity) / Lamp efficiency limit reached,
    • Lamp failure
    • An additional free ON / OFF contact

Lack of technical room ? Go for REUSE manholes!

A lot of small wastewater treatment plants do not have a technical room or lack the space to install a UV disinfection unit. In addition, the hydraulic circuit of the WWTPs is generally gravity, which requires the installation of an additional pump. REUT’s range of manholes simplifies the installation of the reactors, as they are assembled according to the recommendations and can be installed directly according to the hydraulic line of the WWTP.

Wastewater reutilization at the end of the wastewater treatment plant for :

    • Direct REUSE: Irrigation, micro-irrigation, watering,
    • Indirect REUT: groundwater supply
    • Agricultural use:
      • Field crops
      • Vegetable farming
      • Prairies
      • Orchards
      • Vineyard
    • Urban use:
      • Golf
      • Green spaces
      • Race track
    • Wetlands maintenance
    • Bathing area protection
    • Washing water for industrial processes
  • Horizontal or vertical installation
  • Automatic lamp cleaning in line and without disassembly
  • Upstream and downstream sampling

  • Chemical Cleaning Inlet (CIP)
  • LCD interface with UV intensity display,
  • Various voltage-free contacts to complete the supervision
  • Non-chemical treatment: no harmful chemicals need to be added.
  • Easy to install and maintain: automated quartz cleaning to ensure the efficiency of the equipment
  • Economical and energy efficient: low power requirements
  • Acts on a wide range of pathogens, including those resistant to chlorination (certain protozoa such as Cryptosporidium and Giardia).
  • Recognized by regulatory agencies, including the United States Environmental Protection Agency (USEPA).
  • Effective – Destroys 99.99% of microorganisms
  • Ecological: UV does not produce any disinfection by-products that could pollute the environment or limit the reuse of water (as in the case of chlorine or ozone)
  • Reliable: works day and night, 24 hours a day, 7 days a week,
  • Safe for users: no handling of chemicals.Safe for users: no chemical manipulation.
  • Compact and fast treatment: the bacteriological abatement is carried out in the reactor. Water flows through the system without the need for a holding tank or reaction time.
  • Continuous monitoring of disinfection efficiency with remote management to meet operational needs.

Please refer to the supplier’s specific terms and conditions for more information.

All the equipment in the REUSE range is equipped with upstream and downstream sampling ports fitted with flammable valves. Bacterial analysis should be done within 4 hours of sampling, on an average 24-hour sample kept in a cool place. The tests must be accompanied by a UV transmittance measurement at 254 nm as well as a TSS measurement.

REUT reactors are provided ready to be connected and complete. They can be done in 2 ways:

  • Horizontal: the most compact configuration, with top access to the lamps
  • Vertical

Upstream and downstream isolation valves and reductions should not be installed directly on the reactor but close enough to facilitate maintenance operations.

UV lamp maintenance

Before any intervention, remember that :

  1. UV lamps must be recycled according to the regulations of your country. Do not throw them in the regular or industrial waste, as they contain mercury particles.
  2. When replacing a UV lamp, do not put your fingers on the glass. Cleaning the lamps with alcohol will remove any traces.
  3. The light generated by a UV lamp must be carefully protected from direct or indirect view.

When replacing the UVC lamp, be careful not to put your fingers on the glass. Cleaning the lamps with alcohol will remove any finger marks.

When should replacement of wearing parts be considered?

It is recommended to change the UV lamps after 13,000 hours of operation, to maintain the guarantee of a sufficient level of irradiation. This replacement can be done at the same time as the Quartz UV sleeves (if they are damaged). When the sleeves are properly maintained, experience shows that a replacement every two lamps is sufficient (here every 26000 hours / 3 years for example)

How to recycle UV lamps?

That’s easy! Put the old UV lamp in the new lamp package and, for those using original Bio UV reactors, write “recycling” and then ship your used lamps to an approved recycling facility.
