UV Water Purification Systems


Separator Spares & Equipment, LLC specializes in UV Water Sterilizers and UV Water Purification. We provide Ultraviolet (UV) water disinfection systems that are proven, affordable, environmentally friendly technology that can help you ensure the safety of your water supply.

UV water purification systems are the most effective, efficient and cost-effective solution available for maintaining clean drinking water in any setting.

Ultraviolet light is a non-chemical form of water treatment that is lethal to microorganisms. Its radiant energy is in the electromagnetic spectrum between visible light and x-rays. The UV energy is transmitted into a water stream to destroy bacteria, yeast, mold viruses, and algae instantaneously on exposure of predetermined doses of UV light.

UV technology is often used where conventional chlorine disinfection cannot be applied and can be used in the advanced oxidation process (AOP). Key benefits of UV water purification technology include: improving the taste, color, pH, or odor of water, requiring no storage, handling, or transportation of toxic or corrosive chemicals, effective at inactivating a wide range of microorganisms including chlorine tolerant pathogens, and water reuse capabilities to meet sustainability objectives.

Since UV light is not a chemical additive, it does not produce or leave any toxic compounds in water or wastewater, as chlorine does. In the case of chlorine disinfection, residuals are harmful to the environment, so government restrictions have led to users adding other chemicals which do not completely eliminate the hazards of chlorine. In contrast, the UV disinfection system process is an environmentally friendly, safe, sensible, and cost-effective solution that harnesses natural process light to disinfect water, without even affecting the aesthetic quality of drinking water.

In maritime applications, UV sterilizers are typically installed at the point of use (after storage tanks) to disinfect the product water before consumption but may be installed on the seawater desalinator’s (RO) permeate line before entering a product water storage tank as a final disinfection stage.

What are the operating principles of SANITRON Germicidal Ultraviolet Water Purifier?

Sanitron-UV-2400c-Water-PurificationThe SANITRON UV system design has been carefully conceived to provide adequate germicidal dosage throughout the disinfection chamber. The dosage, as it applies to germicidal ultraviolet disinfection, is a function of time and the intensity of germicidal ultraviolet radiation to which the water is exposed.

The exposure time, in seconds, is the total time it takes the water to flow through the disinfection chamber exposing it to the germicidal lamp. Exposure time is related to the flow rate; the higher the flow rate, the lower the exposure time or the lower the flow rate, the higher the exposure time. The ultraviolet intensity is the amount of energy, per unit time, emitted by the germicidal lamp. The dosage is the product of ultraviolet intensity and the exposure time.

The operation of the SANITRON UV system is as follows:
– Water enters the purifier and flows into the annular space between the quartz sleeve and the chamber wall.
– Suspended microorganisms are exposed to the germicidal ultraviolet rays emitted by the germicidal lamp.
– The translucent sight port, or optional germicidal ultraviolet monitor, provides visual indication of germicidal lamp operation.
– The dual action wiper mechanism facilitates periodic cleaning of the quartz sleeve without disassembly or interruption of purifier operation.
– Water leaving the purifier is instantly ready for use, no further contact time is required.

Water quality plays a major role in the transmission of germicidal ultraviolet rays. It is recommended that the water does not exceed the following maximum concentration levels:

Turbidity: < 1 NTU
Manganese: 0.05 mg/1
Total Suspended Solids: 10 mg /1
pH: 6.5 – 9.5
Color: None
Hardness: 6 GPG or 102.6 PPM
Iron: 0.3 mg/1
Tannins: < 0.1 ppm (0.1 mg/l)
UV Transmission: >85% per cm*

* Contact Factory for recommendations on applications where UV transmission is < 85%

Effectively treating water with higher concentration levels than listed above can be accomplished, but may require added measures to improve water quality to treatable levels. If, for any reason, it is believed the germicidal ultraviolet transmission is not satisfactory, contact the factory.

The SANITRON UV system has been carefully designed to provide adequate germicidal dosage throughout the disinfection chamber. The dosage, as it applies to germicidal ultraviolet disinfection, is a function of time and the intensity of germicidal ultraviolet radiation to which the water is exposed. By understanding how these factors work together, you can ensure that your water is being properly disinfected each and every time.

Recommended Installation of SANITRON UV Water Purification System

Installation of SANITRON Germicidal Ultraviolet Water Purifier


The SANITRON UV systems are designed for easy installation. The UV purifier should be mounted horizontally on a flat dry surface. Secure the UV purifier using the mounting holes in the ballast housing or with the optional wall mounting kit. The UV purifier should not be solely supported by its plumbing connections.

The water purifier must be connected to the cold water line only. Inlet water temperature should not exceed 100°F.

Installation requires that a 5-micron sediment filter or finer be installed, in line, prior to the water purifier. The sediment filter will stop or trap large particulates from entering the water purifier. Particulates may cause deposits on the quartz sleeve and interfere with the purifier’s ability to disinfect the water. The sediment filter may also help reduce the amount of routine cleanings of the quartz sleeve.

Shut-off valves should be installed on both the inlet and outlet sides of the water purifier. The shut-off valves allow the purifier to be isolated from the water supply, which is required when removing the quartz sleeve. The use of bypass valves is not recommended.

Unions should be installed on both the inlet and outlet of the SANITRON UV water purification system; this will allow easy removal of the water purifier from the plumbing if required. Apply Teflon tape to threads of inlet and outlet ports to ensure a tight seal.

When all plumbing connections are complete, allow water to enter the water filtration system at a low flow rate until the purifier is full. NOTE: Close the UV water purifier outlet valve to pressurize the chamber. With the UV water purifier pressurized, it should be checked for leaks. Once it is determined that there are no leaks, the inlet valve can be fully opened.

Plug SANITRON UV system into approved ground fault circuit interrupt (GFCI) receptacle. Confirm lamp operation indication at sight port.

How does Ultraviolet water purification work?

UV-Water-PurificationIn simple terms, UV disinfection systems treat water at the right light wavelength, thus destroying the DNA of bacteria, fungi, protozoans, viruses, and cysts.

Water passes through a UV water filter system during the ultraviolet water treatment process. All living organisms in the water are exposed to UV light which attacks the genetic code of the microorganism and rearranges the DNA making it so the microbe can no longer function and reproduce. If a microorganism can no longer reproduce, it cannot replicate therefore, it cannot infect other organisms with which it has contact.

UV water purifiers are very effective at removing microbiological contaminants such as bacteria, fungi, protozoans, viruses, and cysts. Ultraviolet (UV) Water Purification is a proven technology that uses UV light to kill 99.99% of harmful microorganisms in water.

UV water filtration is a safe, chemical-free way to treat water and an environmentally friendly disinfection method.

UV water treatment is a great way to ensure that your drinking and bathing water is safe from harmful contaminants. If you’re looking for an affordable, easy-to-install solution with the peace of mind of knowing it will work effectively, give us a call! Our team can help assess your needs and recommend the best system for your situation.

What are the benefits of adding UV disinfection system to your marine reverse osmosis water maker?

UV lamps combined with reverse osmosis membranes produce clean freshwater without sacrificing good TDS (Total Dissolved Solids). The combination is an excellent choice for marine desalination, wastewater treatment, and commercial/municipal water purification applications.

UV lamps are more effective at killing pathogens than chemical disinfection because the UV light penetrates the cell wall of microbes and disables their DNA, preventing reproduction. UV lamps are proven to kill bacteria, viruses, cysts, and other waterborne pathogens.
