Minimize risk of microbial breakthrough from GAC filters Food and beverage manufacturers commonly use Granular Activated Carbon (GAC) filters, the only technique available, to remove ozone, chlorine and other dissolved compounds from water. Although GAC filters are effective, they are an ideal breeding ground for bacteria that can later contaminate a plant’s water supply and are prone to bio-fouling as well. Without periodic cleaning, sometimes as frequently as once a week, GAC filters can contaminate water used for product manufacturing and other related processes.
Traditionally, GAC filters are backwashed, using steam and large quantities of wash water to clean them and inhibit bio-film formation. However, the process is costly in terms of time, energy and water.
Less cleaning, more productivity Installed immediately after the GAC filter, Atlantium’s Hydro-Optic Disinfection™ system successfully inactivates microorganisms in GAC water, preventing them from moving downstream through production and process lines. The post-GAC application helps manufacturers attain high levels of water quality and as a result, drastically reduce the risk of microbial breakthrough, affording significantly more uninterrupted production. In fact, by reducing GAC filter cleaning frequency by approximately 60%, a leading beverage producer significantly cut system downtime, increased the number of production days and gained greater production efficiency.
Monitoring and control assures continuous disinfection Manufacturers gain additional advantage from Atlantium’s automated Monitoring and Control software that provides real-time, continuous measurement of water UV transmissivity and lamp intensity and receives continuous readings of water flow rate. The software adjusts the required disinfection dose to match the changing conditions. This automatic energy-saving feature continuously provides the correct protection against the microbial threat.
Utilizing Atlantium’s system for post-GAC disinfection, food and beverage manufacturers:
Reduce the frequency of cleaning, and thus, improve production line uptime
Reduce back wash and servicing and associated energy costs
Substantially raise water quality by increasing disinfection levels
