Clean water is becoming an increasingly costly resource, thanks to pollution and increasing regulations, which is why more companies and wastewater treatment facilities are turning to UV disinfection and self-cleaning wastewater systems.
How does UV wastewater disinfection work?
Ultraviolet (UV) disinfection kills or inactivates bacteria, viruses, protozoa and more by exposing them to a specific light wavelength. This can be an effective alternative to the more traditional method of using chlorine to disinfect water. In addition to being a potentially harmful chemical, the stricter the regulations regarding e. coli become, the more chlorine is needed to keep the water up to standard. UV disinfection is relatively safe, doesn’t introduce additional chemicals and is equally effective.
UV systems use special lamps, a ballast and a control system. The lamps vary in intensity depending on your specific wastewater treatment system and needs, and are protected by a clear quartz sleeve. The water is then exposed to UV light at the intensity and duration it needs to inactivate the microorganisms.
UV wastewater disinfection systems have a few drawbacks. First, the quartz sleeves can develop mineral scale, which will reduce their effectiveness. This can be solved by periodic cleaning as well as monitoring the light levels to ensure the best results. Second, operators will need to take care so as not to experience harmful effects of UV exposure. Finally, total suspended solids (TSS) can block the organisms from the UV light and absorb its radiation instead, which renders it far less effective. Operators need to ensure the water has an appropriately low concentration of TSS.
How do self-cleaning wastewater systems work?
Self-cleaning wastewater systems are designed to reduce the amount of TSS in water without additional chemicals, frequent filter changes and backwashing. They’re particularly useful for food and beverage companies that pay more for high levels of TSS in their wastewater (for example, grease, oil and fats).
These systems use a cross-flow filtration system, which helps avoid particle buildup. Instead of collecting on a screen or filter, the particles are more evenly distributed as the water flows through, which cuts down on the number of filter changes and routine cleaning or maintenance that must be done. These types of filters can reduce TSS by up to 60 percent, with a water recovery rate (from effluent) of 99 percent. It also cuts down on the number of chemicals needed to treat the water. Ultimately, self-cleaning wastewater systems are a great way—especially when paired with a UV disinfecting system—for wastewater treatment facilities to save money and get great, eco-friendly results.
