Yes at disinfection rates of 100ppm peroxide (200ppm HuwaSan) over 24 hours or 1000ppm peroxide (2000ppm HuwaSan) over 1hours HuwaSan will kill legionella. Independent tests, by TNO Food and Nutrition Laboratories 2013, show that 2000 ppm Huwa-San (1000ppm peroxide) will achieve a 4.8 log reduction of legionella in 1 hour.
When carrying out a HuwaSan disinfection can the water be used?
Yes at disinfection rates of 100ppm the water can be used. It would not cause harm if somebody drinks it or washes in it. Water systems fed by tanks would generally be classes as non-potable.
Where disinfection rates increase to 1000ppm the system must be taken off line and would not be safe for drinking or washing.
During disinfection when I have achieved 100ppm peroxide at all my outlets. Do I need to flush the peroxide dosed water out of the system?
No 100ppm is the level of peroxide that is required for carrying out a disinfection over 24 hours. It is best to disinfect the cistern and the down services when there is minimum use to give HuwaSan the optimum time to work. There is no requirement to flush the outlets through at this point. When all the outlets are 100ppm peroxide the system should be left in use. 100ppm is safe for drinking and bathing.
I want to carryout a mains water disinfection how would I carry this out?
Mains water disinfections are usually carried out at 1000ppm peroxide over an hour. Generally 3% HuwaSan is good for mains water disinfections as much less product is required due to the small volume of water held in the mains pipework.
What chemical would you recommend to get rid of odours
We would recommend SweetPee to get rid of odours caused by your pets. As it is enzyme based it breaks the smell down rather than masks it. It even works on cat urine which is a really hard smell to get rid off.
We would recommend Checkmate for odours around your home and work place. It can be used to get rid of the smell of urine, vomit, rotting rubbish and cigarette smoke.
What sort of odours does SweetPee tackle?
SweetPee tackles the smell of wee and vomit caused by your pets. It is easy to use simply remove all solids and soak up any excess moisture then spray the affected area.
Is Sweetpee suitable for outside use?
SweetPee is great for outside use. We have customers who use it to spray concrete areas and fake grass. It is great for removing unwanted smells.
How do you use your test strips?
All our test strips are for testing levels of hydrogen peroxide in systems. They are simple and easy to use. Simply dip the strip into the solution to be tested, wait an appropriate amount of time and then compare to the colour scale on the side of the test strip tub.
What is constant dosing?
Constant dosing is when you add a small amount of chemical in proportion to the incoming mains water. This is done via a water meter. The small amount of chemical disinfects the water and helps to keep it free from bacteria. This process like the use of temperature for legionella control has to be closely monitored.
What is Gumdrops?
Gumdrops is a solution that is added to your pet’s drinking water. The solution removes the taste of chlorine from your pet’s water which means that your pet is encouraged to drink more. It also removes plaque from your pet’s teeth which reduces the requirement for brushing and prevents gingivitis.
Is SweetPee safe to use around your pets?
SweetPee is safe to use around your pets as directed. It is to clean the areas where pets may have an accident. Please do not use the spray directly on your pet.
What is the difference between 3, 5, 20 and 50% HuwaSan?
The number at the end of HuwaSan is the concentration of the peroxide in the product. For example Huwasan TR3 is 3% peroxide, TR 20 is 20% peroxide etc.
As the concentration of peroxide in the HuwaSan increases the personal protective equipment that the user needs also increases.
What concentration of HuwaSan is recommended for spa pool disinfection?
The Spa Pool chemical that we sell is 5% peroxide. This is great for spa users who have asthma that is brought on by harsh chemicals like chlorine.
Why would I use HuwaSan, silver hydrogen peroxide instead of chlorine (bleach) to disinfect my water system?
HuwaSan is easier to work with than chlorine. It is a single chemical and does not require neutralisation up to dose rates of 1000ppm peroxide.
It removes the biofilm on the pipework surface where the majority of bacteria will live and multiply.
It is safer for your staff to work with.
It has no odour, taint or smell so if used in spa pools it is much better.
