FAQs

How does a UV disinfection unit purify water in my Blountville home?

A UV unit uses high-intensity ultraviolet light (specifically the germicidal 254-nm wavelength) to penetrate the cell walls of microbes such as bacteria, viruses, and protozoa. The light disrupts their DNA so they can no longer reproduce or cause infection. Water flows through a stainless-steel chamber surrounding the UV lamp, receiving a lethal dose of UV energy in a fraction of a second, all without adding chemicals, taste, or odor to your water.

Do I still need pre-filters if I install a UV system?

Yes. UV light only works effectively on clear water. Sediment, iron, manganese, or organic color can shield microorganisms from UV exposure. We recommend at least a 5-micron sediment filter—and often an activated-carbon filter—upstream of the UV unit. In Blountville, where many households rely on well water with moderate turbidity or mineral content, a simple two-stage pre-treatment ensures the UV dosage remains at the required 40 mJ/cm² or higher.

Will a UV purifier remove chemicals or improve taste and odor?

UV disinfection is designed solely to inactivate microorganisms; it does not remove dissolved chemicals, heavy metals, or hardness minerals, nor does it noticeably affect taste or smell. If your Blountville water contains sulfur odor, iron, or chemical contaminants, you’ll need additional treatment (such as carbon filtration, softening, or reverse osmosis) before or after the UV stage.

What maintenance does the UV system require and how often?

1) Lamp replacement: UV lamps gradually lose intensity and must be replaced every 9–12 months of continuous operation, even if they still light. 2) Sleeve cleaning: The quartz sleeve that isolates the lamp from water can accumulate scale or film; inspect and clean it at least twice a year with a non-abrasive cleaner. 3) Pre-filter changes: Replace sediment and carbon cartridges every 3–6 months or per pressure-drop indications. 4) Annual system check: Our Blountville technicians perform a yearly inspection, verifying UV dose, alarm function, flow rate, and leak integrity.

How much electricity does a residential UV disinfection unit use?

Most residential units draw between 25 and 60 watts—comparable to an LED light bulb left on continuously—costing roughly $3–$6 per month on an average Blountville utility rate of 12¢/kWh. Because the lamp should remain on 24/7 for consistent protection, the low operating cost makes UV one of the most energy-efficient purification options available.

Is a UV system enough to meet Tennessee’s water quality regulations for my business or rental property?

Tennessee Department of Environment & Conservation (TDEC) accepts UV as an approved primary disinfectant when it meets NSF/ANSI Standard 55 Class A performance (minimum 40 mJ/cm² dose) and when an automatic lamp-failure alarm and flow restrictor are installed. For public water systems, you must keep maintenance logs, monitor UV intensity, and perform periodic microbial testing. We supply systems with real-time UV sensors, data logging, and NSF 55 certifications to ensure compliance in commercial, multifamily, and food-service applications in and around Blountville.
