Q: What are STEL and OxiAcWa generators?
A: STEL and OxiAcWa generators are patented electrochemical devices which produces highly effective biocide – OxiAcWa anolyte.
Q: What are OxiAcWa solutions?
A: OxiAcWa anolyte is a solution of mixed oxidants which includes shortly after manufacturing mainly chlorine (Cl2), chlorine dioxide (ClO2) and ozone (O3). OxiAcWa anolyte contains also short-term radicals of oxygen, chlorine and the combination of those two. OxiAcWa catholyte is mainly sodium hydroxide (NaOH).
Q: What is the difference between STEL and OxiAcWa generators?
A: STEL generator requires about 9 grams of sodium chlorine to produce 1 gram of oxidants whereas OxiAcWa requires only 1,7 grams, which is the theoretical limit. The concentration of oxidants is also higher with the OxiAcWa generators.
Q: How powerful biocide OxiAcWa is?
A: OxiAcWa is highly effective against bacteria, fungus, algae, spores and viruses. It is always at least as powerful as chlorine or hypochlorite. However case-by-case it can be even 5 to 10 times more powerful. The difference between OxiAcWa and sodium hypochlorite is that OxiAcWa is also effective against parasites (Giardia, Cryptosporidium).
Q: Is OxiAcWa effective against biofilms?
A: Yes, OxiAcWa removes biofilms and prevents them to be formed. Specially problems caused by algae (cooling towers) can be solved by using OxiAcWa.
Q: How does OxiAcWa differ from sodium hypochlorite?
A: There are three main differences:
- The oxidation reduction potential (ORP) is much higher with OxiAcWa, because it consist of other oxidants than chlorine as well
- Sodium hypochlorite solution is alkaline (pH >12) because it includes lots of sodium hydroxide (NaOH), whereas OxiAcWa is neutral or slightly acid (pH 3-8)
- OxiAcWa solution contains much less chloride
