UV Water Disinfection Devices

UV Water Disinfection Devices
from 0,3 to 1.200 m³/h

UV water disinfection devices used for potable, well water and surface water, swimming pool, spa, waste water, aquariums, fountains etc.

Ultraviolet light is electromagnetic radiation with wavelengths shorter than visible light. UV can be separated into various ranges, with short range UV (UVC) considered “germicidal UV.”

At certain wavelengths UV is mutagenic to bacteria, viruses and other micro-organisms. At a wavelength of 2,537 Angstroms (254 nm) UV will break the molecular bonds within micro-organismal DNA, producing thymine dimers in their DNA thereby destroying them, rendering them harmless or prohibiting growth and reproduction.

It is a process similar to the UV effect of longer wavelengths (UVB) on humans, such as sunburn or sun glare.Micro-organisms have less protection from UV and cannot survive prolonged exposure to it.

Advantages

• More effective against viruses than chlorine.
• Environmentally friendly, no dangerous chemicals to handle or store.
• Νo problems of overdosing.
• Universally accepted disinfection system for potable and non-potable water systems.
• Low initial capital cost as well as reduced operating expenses.
• Immediate treatment process, no need for holding tanks, long retention times, etc.
• Extremely economical, hundreds of liters may be treated with low operating cost.
• Low power consumption.
• No chemicals added to the water supply – no by-products (i.e. trihalomethanes).
• Safe to use.
• No removal of beneficial minerals.
• No change in taste, odor, pH or conductivity nor the general chemistry of the water.
• Automatic operation without speial attention or measurement, operator friendly.
• Simplicity and ease of maintenance.
• No handling of toxic chemicals, no need for specialized storage requirements.
• Easy installation, only two water connections and a power connection.
• Compatible with all other water processes (i.e., RO, filtration, ion exchange, etc.).

Key Factor

A key factor of UV water treatment too proper choose a model is the flow rate: if the flow is too high, water will pass through without enough UV exposure. If the flow is too low, heat may build up and damage the UV lamp.
