We UV Care

Square’s main challenge was removing free chlorine with alternative chemical-free technologies to protect reverse osmosis and de-ionization in pure water generation. Another challenge was maintaining a continuous flow with a low frequency of system downtime and optimized low running costs.

Hygiene and disinfection with UV-C is more important than ever in times of convenience food, MRSA in hospitals, globalisation and industrial agriculture. Particularly where quality and safety are of great importance for humans, animals and products, this efficient and powerful method should be considered.

It may be important to think about the infectious dose of each organism which is essentially the number of pathogens that are required to infect a host. See the article linked below which provides more information on this, including the infectious dose for various organisms.

You have a clean, clear, “water white” 67 Brix sucrose solution with an ICUMSA value of 45 that you want to disinfect with UV. See the attached study which shows how moisture, temperature, and time affect the absorbance of sucrose solutions.

How prevalent are organisms like Legionella, Pseudomonas aeruginosa, and Non-Tuberculous Mycobacterium (NTM) in your incoming water? See some data below from a study done by Weas Engineering.

See the attached presentation from Emilia Rico at BCN Labs for more information about these (and other) spoilage organisms that are found in similar environments.

High doses of UV can inactivate Alicyclobacillus (87mJ/cm2 for a 1 log reduction). See the attached study from ASR Group in the International Sugar Journal.
