An Advanced and Efficient Control of Pathogenic Organisms

Proven Disinfection and Biofilm Protection

Atlantium’s HOD™ (Hydro-Optic Disinfection) UV provides facilities with an energy efficient disinfection solution for hot water system and non-chemical control of pathogenic organisms such as Legionella. It eliminates the potential of corrosion and disinfection byproducts formation associated with chemical disinfection while also positively effecting heat exchanger performance.

The Value of UV for Legionella Control in Cooling Towers

Excessive growth of Legionella in cooling towers and water systems can cause significant negative health effects. In this comparative study, Atlantium’s proprietary medium-pressure HOD UV technology was evaluated and determined to achieve 100% mortality of Entamoeba Histolytica (E. histolytica) at a dose of 8.8 mJ/cm2 systems.

Biofouling from aquatic invasive species (AIS) has profound operational impacts. Mussels and other AIS attach to or clog submerged surfaces including water intakes, trashracks, cooling water piping, fire control systems and more – resulting in flow restrictions and blockages that threaten water delivery and power reliability. The associated costs from lost power production can be significant.

For more than a decade, Atlantium has been working to apply our environmentally sustainable HOD UV disinfection technology to help hydroelectric facilities prevent biofouling from invasive mussel species and their profound operational effects.

The HOD UV treatment solution is proven effective at controlling biofouling from mussels and other AIS, enabling cleaner and more efficient heat transfer in cooling water exchangers. HOD UV is a cost-effective solution using medium pressure UV light and eliminating the need for corrosive chemicals when treating AIS.

Hydro Review: Experiences with Using HOD UV Technology to Control Mussel Fouling

The U.S. Bureau of Reclamation (Reclamation) Lower Colorado Region began a series of feasibility studies in 2007 to assess risk from mussel fouling, outline best low-ecological-impact management practices for coping with invasion, and identify control options for raw water systems to prevent invasion and infestation.

Hydro-Optic™ UV — Proven Biofouling Control of Aquatic Invasive Species

For more than a decade Atlantium Technologies has been applying its environmentally sustainable Hydro-Optic™ (HOD) ultraviolet (UV) disinfection technology to help hydroelectric facilities prevent biofouling from invasive mussel species and their profound operational effects.

Empowering Plants with a Trusted Solution

EPRI 2019 Generation Technology Transfer Award Presented to Plant Bowen

Aaron Nickles, System Owner, Southern Company – Plant Bowen, and Tracy Underwood, Lab Team Leader, Southern Company – Bowen Georgia Power Company received the 2019 Electric Power Research Institute (EPRI) Generation Technology Transfer Award for Plant Bowen’s boiler feed water dechlorination using Atlantium’s HOD UV.

Power Plant in Pinghu, China Installs HOD UV for Non-Chemical Disinfection of Boiler Feed Make-Up Water

A power plant in Pinghu, located within the Zhejiang Province, China, installed the HOD UV treatment system to replace the use of chemical biocides and protect boiler feed make-up water from anaerobic and aerobic bacterial growth and associated biofouling. The facility has achieved non-chemical boiler-feed make-up water disinfection using the HOD UV technology.

Why Atlantis UV?

TECHNOLOGY

Total Internal Reflection

Atlantium’s HOD UV technology is based on medium-pressure lamps which are shorter and more powerful than low-pressure lamps. Medium-pressure lamps’ conversion rate (rate of converting electricity to UV light) is about one-third of that of low-pressure lamps and as such, many conventional UV systems that use medium-pressure lamps are less energy-efficient than most conventional UV systems using low pressure. HOD UV systems are designed with an optical amplification mechanism that recycles UV photons within a quartz-made disinfection chamber making them even more power-efficient than low-pressure Systems.

The core of the HOD disinfection system is a disinfection chamber made of quartz and surrounded by an air block. This configuration helps trap the UV light’s rays and forces them to repeatedly bounce inside the chamber in a phenomenon referred to as Total Internal Reflection (TIR). The ray’s long path inside the chamber combined with an optimally engineered flow of water in a controlled, defined pattern, creates a uniform UV dose distribution that reaches and achieves 4-log* virus* inactivation of microorganisms throughout all the water running through the chamber. This is one of the key elements to attaining high levels of microbial 4-log* virus* inactivation and electrical consumption.

Superior Control & Monitoring: Dual Sensors Configuration

As UV transmittance (UVT) and lamp output are measured separately, the HOD UV system automatically adjusts lamp power when conditions fluctuate so that the minimum required dose set by the user is guaranteed to be delivered. This also contributes to efficient power consumption as lamp power can vary between 25-100% according to the production stage and condition. The appropriate dose and operational mode are tailored by Atlantium’s team so that they meet our customers’ specific needs.

A user-friendly touch screen panel provides the user with important operational information such as delivered dose, flow rate and water UVT. In addition, it records each lamp’s total number of operating hours and can activate alarms if lamp intensity drops below the minimum set level. A remote-control module enables the user to monitor and access the system when offsite. The data logging system enables traceability over time to monitor delivered dose, power consumption, UVT, flow rates and additional factors for secure production cycles.

Superior Control & Monitoring: AiO Controller

Setting a new standard in precision, monitoring and operation of UV systems! Atlantium’s Hydro-Optic™ (HOD) UV systems feature the All-in-One (AiO) Controller — the most advanced operation module in the market, providing unparalleled user experience and more reliable system information than ever before.

Accurate control and monitoring of a UV system are critical for its efficient operation and water biosecurity. The AiO Controller features an elegant touch-screen interface, with a display at a glance of lamp power, flow, UVT, and UV dose. The innovative solution offers peace of mind and quick access to essential information about each individual UV lamp, including status, operation hours, number of ignitions and efficiency.

The controller is operated through a secure user-management tool that allows different permissions to different users. Authorized operators can easily configure output signals, UV dose and operation mode and Parameters can be stored and retrieved for efficient operation. The AiO Controller event log records and displays up to 1000 events with detailed information. The AiO controller also keeps records of system parts’ repairs, replacement and calibration, making maintenance transparent and trackable.

The AiO Controller can be connected to a remote computer for advanced service and support, remote monitoring, connection to SCADA and for generating reports of all recorded parameters in specialized formats complying with a wide range of regulations.
