Point-of-Entry (POE) Water Treatment Systems: The Ultimate Guide to Safe and Clean Water

Discover the benefits of Point-of-Entry (POE) water treatment systems and learn about the revolutionary PearlAqua Deca UV POE water disinfection system for clean, safe water.

Point-of-Entry (POE) Water Treatment Systems: The Ultimate Guide to Safe and Clean Water

Are you considering installing a water treatment system for your home or business? Point-of-Entry (POE) systems provide comprehensive water purification and treatment for your entire property, ensuring clean and safe water for various applications. Read on to learn more about POE systems, LED UV water treatment, and how the innovative PearlAqua Deca UV water disinfection system, supplied by LED UV-C Systems Ltd, stands out in the market.

What is a Point-of-Entry (POE) Water Treatment System?

A Point-of-Entry (POE) water treatment system involves installing water treatment equipment, such as an ultraviolet water treatment system, on the main incoming water line to a property, be it a home or business. POE systems treat all water entering the property, except in some cases, water used exclusively for irrigation purposes may be left untreated. This comprehensive approach ensures clean and safe water for various applications throughout the property.

Point-of-Entry (POE) vs. Point-of-Use (POU) Water Treatment Systems

It's essential to differentiate between Point-of-Entry (POE) and Point-of-Use (POU) water treatment systems. While POE systems treat water at the main incoming line, ensuring comprehensive treatment and water purification for the entire property, POU systems treat water only at a single tap or application, providing localised water treatment.

UV Sterilisation: Effectively Inactivating Harmful Pathogens for Safe Drinking Water 

How UV sterilisation inactivates a wide range of harmful pathogens, including bacteria, viruses, protozoa, and fungi, ensuring safe and clean water for your home.

UV Sterilisation: Effectively Inactivating Harmful Pathogens for Safe Water

UV sterilisation has emerged as an effective method to inactivate a wide range of harmful pathogens, ensuring safe and clean water. Learn more about the types of pathogens that UV sterilisation targets and how this technology can help protect you and your family from waterborne illnesses.

Bacteria: Eliminating Common Culprits of Illness

UV photons effectively inactivates harmful bacteria such as E. coli, Salmonella, Legionella, and Shigella, which can cause gastrointestinal illnesses, pneumonia, and other infections. UV sterilisation is a powerful tool in protecting against bacterial contamination in water supplies.

Viruses: Neutralising Viral Threats

UV water purification can neutralise viruses, including norovirus, hepatitis A, rotavirus, and influenza, which can cause a variety of illnesses, such as gastroenteritis and respiratory infections. By targeting viruses, Ultra-violet disinfection helps ensure safe and healthy water.

Protozoa: Inactivating Waterborne Parasites

UV-C treatment can effectively inactivate waterborne protozoa such as Cryptosporidium and Giardia, which can cause gastrointestinal illnesses like diarrhoea, nausea, and stomach cramps. UV sterilisation helps to safeguard against these common waterborne parasites.

Fungi: Controlling Fungal Contamination

UV water disinfection can also help control certain fungi and mould spores, which can cause allergies, infections, and other health issues. This additional layer of protection is especially beneficial in maintaining clean and safe water.

Factors Affecting UV Sterilisation Effectiveness

The effectiveness of any UVC water sterilisation system depends on factors such as the intensity of the UV light, the duration of exposure, and the specific wavelength used. It is crucial to ensure the water is clear and free of particles that could shield pathogens from UV light. Trust in LED UV-C Systems Ltd's expertise to provide effective UV sterilisation solutions for your water treatment needs.

PearlAqua Deca: List

Conventional UV Power Use

Conventional mercury systems are typically left on 24 hours a day 7 days a week due to warm up times and restriction on cycling. This uses unnecessary power if water is not in use, costing money and wasting energy.

Common UV LED Power Use

UV LEDs offer instantaneous on/off capabilities with 100% power within nanoseconds. This however, does not account for the variations in flowrates in whole house systems, so the UV LEDs treat the water at full power 100% of the time.

Dynamic Power Control
Only With PearlAqua Deca

Beyond instant on/off capabilities of UV LEDs, PearlAqua Deca features Dynamic Power Control, providing optimum performance across all flow rates– saving you money with a lower electric bill. When low flow rates are detected, the system adapts and lowers the power consumption.
