Surespa Ltd launched an innovative, active oxygen based hot tub water treatment product, eco3spa, onto the market in February 2019. Since the product launch online sales have increased very rapidly and dealers have been recruited throughout the UK, France and now Germany. The popularity of the product stems from the fact that it is free of both chlorine and bromine, which are bad for the environment and frequently cause unpleasant odour and skin irritation. Additionally, there is no need to continuously test the water and balance the total alkalinity and pH, as is required when using chlorine, thus making the hot tub significantly easier to maintain.
Domestic hot tub water typically remains in the tub for 3 months, so adequate and ongoing sanitation is crucial. It is important that independent and validated test data is available to prove that a product is effective and safe for use.
eco3spa comprises three components:
An MSc research project was conducted at Swansea University during 2019/2020 to look at the sanitising and biofilm control efficacy of eco3spa with positive results. This research confirmed that the Step 3 Active Oxygen Tablets perform at least as well as chlorine in killing common contaminants, Escherichia coli and Pseudomonas aeruginosa, at a range of relevant water temperatures and pH values, validating the assertion that constant pH balancing is not required when using the product. The study also looked at the effect of the Step 2 Conditioner on the performance of the active oxygen and appeared to show that, although the Conditioner didn’t reduce live bacterial replication it did appear to make the cells clump and switch to a viable but non-culturable state.
This new study will build on the previous research to further study the performance of active oxygen as an effective sanitiser over a period of time after it is added to the water and to look in much more detail at the role the Water Conditioner plays in the sanitation process.
