Guarantee Safe Water by Using UV as a Firewall

Aquionics UV Light Sanitary Process

Sure, you have heard the buzz about using UV in your plant for disinfection, but let‚Äôs talk specifics‚Ķ. How can you truly put UV to work in your plant, realize the benefits from the first step of your process AND justify the cost? It‚Äôs simple‚ÄĒput UV to work as a¬†firewall¬†in your plant to guarantee safe water for your process and FSMA compliance.


When we talk about water quality and disinfection in processing plants, we like to focus on three main issues:


  1. Municipal water supply challenges
  2. FSMA compliance
  3. Brand protection

Using UV technology as a firewall in your sanitary processing plant is your answer to these concerns. 


But Municipal Water is Treated, Isn’t It?


Yes, the water is treated, but let’s talk about the distribution system for the treated water. According to a 2006 EPA study, more contamination events are due to issues with the distribution system than to source water contamination. But why?


  • ¬†Infrastructure is aging and old pipes are leaking
  • ¬†Pipes are breaking and broken pipes are a source of contamination

Are you prepared and protected if a slug of dirty water makes contact with your plant? What would be the potential impact of using untreated water in your process or product? If you are thinking, ‚ÄúBut we have never had a problem,‚ÄĚ you aren‚Äôt alone. However, the number of food borne illnesses and hospitalizations is staggering. UV treatment of your process water as it comes in the plant protects both your product and your consumer.¬†


So is City Water Acceptable for FSMA Compliance?


Not only is safe water important for protecting your product, but it is an enforced regulation. According to the FSMA section 117.37(a), it is required that the water supply be sufficient for the operations intended and be derived from an adequate source. This leaves us with the question of ‚ÄúSo is city water acceptable?‚ÄĚ Of course it is acceptable, but how do you know?


There are two ways to know if city water is acceptable:


  1. Increased microbial testing of the incoming water
  2. Some form of treatment of the water before it goes into the process

In order to truly comply with FSMA, the FDA will be looking at how processors are ensuring how guidelines are being met. This means documentation. The best way to meet the FSMA requirements for 117.37(a) is UV. UV provides real time measurement of dose, is easy to document and guarantees microbial inactivation.  


Good Business 


Aside from possible regulatory pressure or concerns about the water supply, why would you want to implement UV as a firewall in your plant? Brand protection.  


UV helps:


  • ¬†Minimize the risk of microbial contaminants entering the plant and contaminating the product
  • ¬†Ensure confidence that waterborne microbial contaminants will be inactivated instead of potentially leading to a costly and detrimental product recall
  • ¬†Potentially increase product shelf life when water is used as an ingredient

If bad water enters your plant and there is no treatment, what kind of impact could that have on your operation? 


Get the Facts About UV


Do your plant’s practices hold up to FSMA compliance? Get the facts to see if what you are already doing is enough, or if adding UV to your disinfection process as a firewall would benefit your process. 


  • ¬†Never had a problem with the water supply?
    • ¬†Although you may have never had a problem that you are aware of, you need to take into account the new restrictions put in place by the FSMA. You will need to document that you have no problem and be able to produce that documentation.
  • ¬†Already testing the city water once per week and it is typically pretty clean?
    • ¬†With the volume of water being used daily, is that frequency of testing a great indicator of what‚Äôs happening in real time? How would you know if bad water entered the facility? How would you respond if the water testing showed high microbial counts (48 hours¬†after¬†the water was already used)?
  • ¬†Already using RO, and don‚Äôt need UV?
    • ¬†Are you well protected in case there is a breakthrough in the RO membrane?¬† UV in front of RO will inactivate the organisms, reduce biofouling of the RO (reducing cleaning frequency of the RO), and help to ensure that if a breakthrough does occur that the organisms are inactivated.
  • ¬†Using carbon already?
    • ¬†Carbon is a breeding ground for microbial contaminants.¬† UV should be installed post-carbon to ensure that growth does not get into the process.
  • ¬†Most of your water goes through a multi-barrier treatment process currently?
    • ¬†FSMA will result in manufacturers having to think about ALL of your water.¬† Is the water used for CIP treated?¬† How about the water used for rinsing bottles, packaging, etc.?¬† All water should be ‚Äúsufficient for the operations intended‚ÄĚ.¬† Is¬†all¬†water being treated?

Justify the UV Expense


We know that municipal water concerns are well documented, FSMA compliance is an upcoming hot topic and food safety is always a constant concern. Get ahead of the curve before FDA can ask questions about your lack of compliance and treat water before it has a chance to cause compliance and safety issues for your brand.


Guaranteed disinfection and safe water can provide invaluable peace of mind. Contact a Rodem representative today and see the small price to implement UV as a firewall and get this assurance for your process, product and consumers in the long run.
