Turbidity
Turbidity counts as a simple and basic indicator of water quality.
Caused by small particles, turbidity is not considered a physical quantity – it’s merely a subjective optical impression. Turbidity is determined by sending a light beam with defined properties through a sample. The scattered light that results from the particles is then measured.
Did you know that due to the molecular scattering, no turbidity = 0? Turbidity values below 0.0016 are not visually measurable
Depending on the measuring angle of the applied light, the unit for turbidity is specified in NTU, FTU, FAU, FNU or TE/F. In order to be able to comparably measure turbidity, formazine – the standard turbidity liquid – was created. All other liquids give differing results at the different measuring angles.
The Austrian drinking water standard stipulates a turbidity value of no more than 1.0 NTU.
Did you know that increased turbidity in the EDM area may indicate organic contamination or a problem in the filter system.
Organic contamination
Contamination by organic substances is given too little consideration in industrial production. Organic impurities can lead to microbial contamination of the machine components and thus form deposits of slime, algae or mould.
Reverse osmosis is the optimal choice here. The fineness of filtration is 0.0001 µm.
Thus, microorganisms are almost completely filtered out of the water.
Types of membrane filtration
Did you know that a large proportion of additives are the best breeding ground for bacteria, algae and mould?
Depending on the type of contamination, handling and inhalation can be harmful to the user’s health.
Did you know that organic contamination can be responsible for poor filter life?
