Wendy Quinn started her water filtration parts business in 1986 with an initial focus on the semiconductor industry.
Ultraviolet Water Treatment with pre-filtration is a process that uses ultraviolet light to disinfect water or reduce the amount of bacteria and viruses present in source water. UV treatment works in the same way as strong sunlight does to purify water by making biological impurities inactive.
UV systems are used for the disinfection of pressurized wastewater, surface water, process water, and other low UV transmittance liquids. The WEDECO UV systems shown here meet the U.S. Environmental Protection Agency's UV Disinfection Guidance Manual and the National Water Research Institute (NWRI) guidelines, including the most stringent California Title-22 Water Reuse standards.
An industrial ultraviolet system reactor within a large scale drinking water treatment, filtering and high-performance purification levels using dose mode UV disinfection technology with self-cleaning quartz tubes. The water plant operator is able to change the UV lamp modules while the system is still under pressure.
WEDECO Duron is an open channel UV disinfection system for mid-size to large wastewater applications. The WEDECO Duron eliminates the need for chemical based disinfection while simultaneously reducing electricity costs and the amount of space required to reduce pathogens.
While we only supply the finished product, we thought you might be interested in seeing just how the ultraviolet water purification products we sell are made. Please note that this example reflects the manufacturing process of just one of our major suppliers to increase UV disinfection performance.
Changing a UV lamp in both small and large scale systems is a delicate job that requires the use of safety glasses. It can be done by anyone with a steady hand provided they have adequate room to maneuver and a safe location to place the fragile parts while working.

This is another example of servicing a commercial UV system from Aquafine. While we hope you find it informative, please be sure to follow your specific product installation procedure guidelines as they may vary between manufacturers.
Ultraviolet Water Treatment with pre-filtration is a process that uses ultraviolet light to disinfect water or reduce the amount of bacteria and viruses present in source water. UV treatment works in the same way as strong sunlight does to purify water by making biological impurities inactive.
This is because every cell of a living organism contains DNA (except many viruses, which only contain RNA), which allows the cell to function and reproduce. UV-C light from germicidal ultraviolet lamps is able to penetrate the cells of certain pathogenic microorganisms and disrupt the structure of their DNA molecules, preventing them from being able to perform vital cellular functions or to reproduce.
UV treatment removes the health threat from water-borne pathogens without creating the toxic disinfection by-products produced when chlorine is used for drinking water disinfection. UV technology is certainly a better alternative to chlorine disinfection because the deployment of chlorine, chlorine dioxide, hypochlorite and other chemical substances to disinfect liquids can result in effects which are detrimental to both public health and the environment.
While Ultraviolet Treatment Systems are not effective in removing chemicals, they have a very high effectiveness in removing protozoa (ie. Cryptosporidium, Giardia – organisms resistant to chlorine that are a major risk to human health.); bacteria (ie. Campylobacter, Salmonella, Shigella, E. coli); and viruses (ie. Enteric, Hepatitis A, Norovirus, Rotavirus).
With ultraviolet technology, it is possible to destroy more than 99.99% of all pathogens within seconds but one should note however that it is impossible to inactivate every single pathogen that ever passes through a large scale UV system regardless of what disinfection method is used, whether it is UV, chlorine or anything else. What is possible is that the pathogen levels are reduced by a predictable amount.
There are UV guidelines from the National Water Research Institute (NWRI) which apply to the disinfection of drinking-water supply sources. This includes filtered surface water, unfiltered surface water, and groundwater. For filtered surface waters, water treatment processes prior to UV disinfection could include granular or synthetic medium filtration, membrane filtration (microfiltration [MF], ultrafiltration [UF], nanofiltration [NF], and reverse osmosis [RO]), diatomaceous earth filtration, or slow sand filtration.
Complete sterilization is not necessary for the production of potable water. However, the water must conform to the drinking water standards of the EPA or those of the agency governing your supply. Normally, the water must contain less than 2.2 coliforms per 100 ml to be considered safe to drink. The coliform groups of microorganisms are generally associated with fecal matter and indicate that pathogenic (disease-causing) organisms, such as typhoid, may be present.
The ultraviolet output of the UV lamp system is dependent upon its primary voltage output and the lamp wall temperature. For example, at 56.6 F (12C) the lamp will be only 22% efficient in generating bactericidal radiation. To achieve 100% UV output, high intensity ultraviolet lamps should reside within a high-transmission clear fused quartz jacket so that the liquid being sterilized does not come in contact with the lamp and maintain an optimum temperature of 104 F (40C). This is because the raw source water inlet temperature is assumed to be 55°F (a national average which may vary depending on the geographic location), even though some RO systems utilize preheating to decrease the feed pressure required for reverse osmosis.
Another factor that must be considered is the useful life span of the UV lamp. Since the ultraviolet output and effectiveness of a UV lamp gradually decreases over time, it must be replaced as indicated by the manufacturer's stated hours of use or by a UV monitor. It is recommended that spare ultraviolet lamps be kept on hand at all times (but not for so long as to reduce their effectiveness if that is a factor) and that accurate records be kept of ultraviolet lamp use and replacement schedules, for both safety and legal concerns in the case of a contamination event.
More and more public water utilities are now switching from chlorine disinfection to UV disinfection for wastewater treatment, which is much more environmentally friendly and has no adverse effect on aquatic or marine life.
The effectiveness of a UV disinfection system is, in part, maintained by the performance of the cleaning system. Iron, calcium, aluminum, manganese, and magnesium have been observed to impact the effectiveness and frequency of cleaning requirements. Site-specific testing is recommended when any of these minerals or water-quality effects such as inorganic and organic constituents are present at concentrations that can result in the fouling of the quartz sleeves.
Please contact us whenever you need replacement parts for any type of water purification system component, regardless of manufacturer. Simply give us the part number and we'll provide you with a quote for your consideration and arrange delivery upon acceptance.
Kindly note that we do not design, manufacture, engineer, or service water treatment systems. Our business is focused solely upon offering you very low prices on consumables and repair parts for existing commercial and industrial OEM water purification systems, regardless of the application.
Our California office is open Monday through Friday from 8:00am to 5:00pm Pacific Standard Time, but you can write to us anytime and we'll get back to you as soon as possible, often after-hours, because we know that emergencies happen. We will ship worldwide with the exception of high fraud risk countries.
One of our goals is to continue to offer our customers the most up-to-date water treatment equipment and technology. So, if you are a water treatment component manufacturer looking for an established filtration parts and consumables wholesale distributor for your product line, or a procurement company seeking "women owned small business" bids for the government or an equal opportunity based publicly-traded corporate client, give us a call. We'd love to hear from you.
Looking for used water filtration equipment? We might have a client who is looking to sell their second-hand purification units after they've been replaced by a larger capacity system.
