Did you know, when it comes to the disinfection of water systems Huwa-San is a far superior product to chlorine bleach. Here’s why …
1. Huwa-San is environmentally friendly. Chlorine is not!
Huwa-San breaks down to oxygen and water. Research carried out by the CDC (Centre for Disease Control and Prevention), found that over 600 by-products have been identified in chlorinated tap water, including halo acetic acids and tri halo methanes. These can cause cancer. Chlorine and chlorinated compounds have an adverse effect on the flora and fauna of streams and rivers.
2. Huwa-San is very stable. Chlorine is not!
Chlorine is highly reactive with organic materials and ammonia-based chemicals. Chlorine flashes off in calorifiers. Huwa-San is much less reactive and can remain in water systems, until diluted out by make-up water. Huwa-San is stable up to temperatures of 95 Degrees C.
3. Huwa-San is easy to use. Chlorine is not!
Following a disinfection chlorine must be neutralised before the system can be drained safely drained, refilled and recommissioned. Huwa-San simply stays in the system and continues to protect it.`This means that a Huwa-San disinfection costs 60% less than a chlorination.
4. Huwa-San is an amazing biofilm remover
Huwa-San will penetrate and remove stubborn system biofilms which include legionella and pseudomonas bacteria. Whereas chlorine only reacts with the outer layers of biofilm before it is spent. It can only therefore remove newly formed biofilm.
5. Huwa-San is loved by operators
Chlorine not so much! Operators love using Huwa-San because only one chemical calculation is required. It is easier to work with. Less clothes are destroyed during the disinfection process and there is no smell or odour from the Huwa-San products. We get amazing positive feedback from technicians on Huwa-San who have used both products.
6. Huwa-San doesn’t require pH correction whereas Chlorine does
Huwa-San will work across a wide range of pH which means that disinfection levels are not affected by the pH. In water, sodium hypochlorite (liquid bleach) forms hypochlorous acid, which is the biocide that disinfects water. It is most effective when the pH is 7.2-7.6. However, at a pH of 8 it is only 20% effective which means it is important to monitor the pH during a disinfection when using chlorine. Chlorine cannot be used for disinfection systems in London, where the softened water in the system has a pH of 9.0.
7. Huwa-San is a modern biocide/disinfectant
Chlorine is yesterday’s biocide. Huwa-San has been researched and developed over the past 40 years. It has been extensively tested in the lab and in the field. It is a biocide that has been specifically formulated to kill bacteria, fungi and mould in water systems. Chlorine bleach is a by-product of another manufacturing process. Its lack of stability, poor eco credentials, and inability to remove mature biofilms means that it has outlived its usefulness.
8. Huwa-San can kill algae and cryptosporidium. Chlorine cannot!
Huwa-San will kill algae and unsightly blooms whereas chlorine bleach is ineffective against algae.
Huwa-San also kills Cryptosporidium: Chlorine cannot.
9. Huwa-San is kind to metals and seals. Chlorine is corrosive.
Water disinfection usually gets carried out at 100-1000ppm peroxide (200-2000ppm Huwa-San TR50). Levels up to 3% peroxide will not corrode copper, stainless steel, or other metals. Chlorine can cause corrosion to system metals and perish system seals. Huwa-San should be the disinfectant of choice for stainless steel systems where chlorine can cause general corrosion and possibly stress corrosion cracking.
10. Huwa-San is fantastic for constant dosing
Huwa -San is registered under the BPR by Roam Technology under product type 5 for the disinfection of animal and drinking water. It is used throughout the world in agrochemical, agrochemical and industrial water systems to maintain system cleanliness and keep water bacteria free. Chlorine’s inability to remove biofilm makes it unsuitable for most continuous dosing applications.
