The Melaklean Cleaner Air Products microbial test DIY kit can be used on process water, drinking water, waste water or recycled water, and gives an answer in 24 hours.
In addition, the test solution changes colour depending on the level of bacterial contamination. The colour is compared with a colour chart fitted on the test device.
The test kit is suitable for aerobic bacteria. Examples of bacteria it can show presence of (non-specifically) are Coliform, E-coli, Giardia, Cryptosporidium, Campylobacter, Listeria and Legionella.
It can be used for cooling tower water, to obtain a heterotrophic plate count, thus a fast snapshot of the condition of the cooling tower.
If the sample water contains a high concentration of fungi, the fungi (eukaryotic cells) will ingest the active indicator, reduce it and turn pink. Total Microbe will provide fungi detection when present at high levels.
The red specs represent fungi colonies which are producing polysaccharides and they are looking for surfaces (side walls) to attach themselves to (filming). Fungi specs will be irregular in size and shape. Find 20 or 30 specs and they are a relative indication of high concentration level and environmental stress.
