To determine the appropriate HOD UV system, we need the following information: UV Transmittance (UVT) at 254 nm Maximum and minimum flow rates Required UV dose Target pathogens Key water quality parameters Additionally, a treatment process flow diagram helps us understand the existing setup. Further information may be required for specific applications such as pH
Yes, you can use your existing flow meter if it provides reliable reading and there are no diversions between the flow meter and the UV system. It is crucial that the flow signal accurately represents the flow through the UV system, with no risk of measuring flow when the UV system is bypassed. The flow
Ultraviolet Transmittance (UVT%) measures how much UV light at 254 nm passes through 1 cm of water. To measure it you will need a spectrophotometer (we recommend using a portable one), quartz cuvettes, and reference water (can be distilled water). How to Measure UVT%: Prepare the Spectrophotometer Turn on the spectrophotometer and allow it to
If no UVT% test sample is currently available, you have a few options: Atlantium personnel can bring a portable UVT% meter for on-site testing during a scheduled visit. Alternatively, you can send a sample to your Atlantium salesperson for testing. Please ensure the sample is in a 100 ml plastic bottle with a sealed cap,
UVT%: Measures how much UV light passes through water, indicating UV-absorbing contaminants. Turbidity: Measures water cloudiness due to suspended particles, reported in NTU. They measure different aspects of water quality and are rarely correlated.
Low-Pressure (LP) UV: Emits a single wavelength (253.7 nm). Produces less UV light overall, requiring more lamps in the system for effective coverage. LP Lamps operate at lower temperatures and therefore each LP lamp is more energy-efficient than an MP lamp. Limited versatility in handling a variety of contaminants, as it does not damage microorganisms’
Total Internal Reflection (TIR) is Atlantium’s patented technology that enhances UV disinfection by uniformly distributing light throughout the inactivation zone, effectively concentrating UV energy for optimal microorganism inactivation. At the core of this system is its uniquely designed chamber, made of high-quality quartz surrounded by an air block instead of traditional stainless steel. This innovative
Unlike quartz chamber surrounded by an air block and stainless steel, traditional polished stainless steel chambers do not reflect UV light. Instead, it absorbs UV energy, reducing system efficiency.
The HOD MP UV system effectively removes Free Available Chlorine (FAC) by targeting both forms present in water—hypochlorous acid (HOCl) and hypochlorite ion (OCl⁻), each with unique absorption characteristics. At pH levels below 7, the process will require more UV energy for breakdown. As pH rises, the process will require less UV energy for breakdown.
Our lamps are designed for exceptional longevity. However, operational parameters can influence their performance. Based on our accumulated data, we've observed that actual lamp life often surpasses the rated duration, with some cases showing impressive longevity depending on the number of ignitions. Our lamp replacement alerts are triggered by real-time sensor readings that measure the
