Disinfection Systems Treatment

Ultraviolet Disinfection Process

What is Ultraviolet (UV) light?

Electromagnetic radiation with wavelength from 10 nm to 460 nm, shorter than that of visible light but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the sun. It is also produced by electrical and specialized lights, such as mercury lamps, tanning lamps, and black lights. The chemical and biological effects of UV are greater than simple heating effects, and many practical applications of radiation derived from its interactions with organic molecules. Short-wave ultraviolet light damages DNA and sterilizes surfaces with which it comes into contact. For humans, sun tan and sun burn are familiar effects of exposure of the skin to UV light, along with an increased risk of skin cancer.

How does UV work?

Ultra violet photons harm the DNA molecules of living organisms, such as viruses DNA molecule, so that it will not function properly, such as in reproduction. Ionization is the process where an atom/molecule gains or loses an electron. An Ionizer works by electrostatically charge negative ions internally and disperse them into the air. Like a magnet, the released negative ions will merge with positive ion particles in a room. This includes dust mites, pollen, pet dander, bacteria, and viruses. The bonded ions will fall due to the increased weight leaving the air free from any contaminants. Owners will have to vacuum/clean up the particulates on the ground or wall.

Ultraviolet disinfection systems are used in the wastewater treatment industry to remove

micro-organisms, such as fecal and E-Coli organisms in wastewater. We do know that these are micro-organisms and are not viruses, but the process of disabling them both will work with viruses as well. Wastewater Depot LLC has also used this process in both for water and airborne applications on using this UV technology for applications to disable some virus that exists in places such as hospitals and nursing homes where we know the virus exists. The virus is in the range of

parts per billion not parts per million, so it is hard to find.

To meet disinfection requirements for packaged wastewater treatment system many are supplied with the Horizontal channel type Unit to meet the quality effluent limits required at the discharged. The Wastewater Depot Ultraviolet Disinfection system is available. The Wastewater Depot, LLC Horizontal Channel Type of packaged treatment systems disinfects wastewater flows ranging up to 500,000 US gallons per day (GPD). The Wastewater Depot Horizontal Channel Type’s most significant features are the small footprint and its ease of operation.


The Wastewater Depot ultraviolet disinfection (UV) system comes standard with a stainless steel channel and built-in level control weirs, remote NEMA modified stainless steel enclosures with window kits and removable waterproof modules.


In order to meet the effluent discharge permit limits, the UV system will require maintenance. Lamps will need to be replaced every 8,500 hours. Due to the heat of the lamps and the harsh nature of the wastewater, the quartz sleeves (the protective material over the lamps) will also need to be cleaned and possibly replaced. Fouled quartz sleeves will prevent the UV light from penetrating the wastewater solids passing through the trough and thus will reduce system efficiency. An operator is required to remove the modules and clean the quartz sleeves with a lime, calcium or rust remover. This can be done on a work table or on a cleaning rack.
