SolarBee – Potable water treatment

General Overview Tecnology Fresh Water Applications Potable water treatment Wastewater Applications Models & Specifications

Stagnation in Potable Water Storage Reservoirs Can Cause:

  • Loss of residual chlorine leading to excess chlorine usage and disinfection by-products.
  • Thermal stratification, which reduces the mixing effect of normal inflow and outflow.
  • Nitrification associated with chloramine.
  • Excessive ice buildup in cold climates.

In potable water distribution reservoirs, the SolarBee can be installed to provide thorough mixing to reduce problems associated with long water age and loss of disinfectant. The SolarBee can also be used for boosting chlorine or chloramine in the reservoir, and for break point chlorination if the reservoir is taken off line. In these applications the SolarBee is typically installed through a top hatch (using bolt-apart or collapsible models), and the solar modules and battery are mounted on the roof.

Advantages of using SolarBee in potable water reservoirs:

  • Models are available for reservoir volumes of 750 – 150.000 m3 per SolarBee. This flexibility allows us to select the best equipment for your reservoir.
  • The SolarBee thoroughly mixes the entire reservoir, reaching all the dead spots, even in large reservoirs with hundreds of support columns. Breakpoint chlorination can be accomplished by injecting chlorine into the SolarBee impeller area.
  • The SolarBee has little or no energy cost, a 25 year expected life, and virtually no maintenance. It comes with a two year parts and labor warranty.
  • The SolarBee flotation system, together with the variable length intake hose, self adjusts at all times for peak performance regardless of water depth in the reservoir. No other mixing system does this.
  • Although the various models range from 300 to 500 cm in diameter when fully assembled, the SolarBee’s design allows it to be disassembled and brought into the reservoir through a 60 cm x 60 cm opening. Trained factory technicians perform all installations.
  • Unlike nozzle devices applied to the inflow-outflow piping, the SolarBee causes no detrimental effect on system flow rate capability, no loss of energy at the nozzle, no losses in pump efficiency, and no changes to other distribution system characteristics. Also, by definition, when extra mixing is needed the most is when there is very little flow available to make the nozzle system perform at all.
  • High speed turbulent mixers have a very short distance of influence unlike the SolarBee which mixes the entire reservoir. The SolarBee has far less electrical and maintenance costs, and there is no high voltage in the reservoir. Also, the SolarBee has stainless steel construction instead of cast iron, and the SolarBee is not subject to problems of cavitation or being run dry.
  • The SolarBee can be equipped with SCADA output signals, a chlorine injection system, and with various solar and 24-hour power kits as needed depending on reservoir characteristics.
