Water and quality water are important for both human health. Water quality is also important for equipment and utility systems. Several water quality parameters such as
water_cock, manganese and hardness do not pose a risk to human health but damage equipment and surfaces in contact with water, such as sanitary ware, ceramics, household appliances and heating equipment. Requirements for drinking water quality are regulated by Regulation No. 82 of the Minister of Social Affairs of 31 July 2001 “Requirements and methods of analysis for drinking water quality and control”
You can find the form of water analysis performed by Callefiks OÜ here.
The following is an overview of some of the water quality parameters and their impact:
The health effects of ammonium in drinking water are very small compared to the amount obtained from food. The maximum level of ammonium in drinking water is 0.5 mg / l.
ODOR and TASTE
The smell and taste of water are affected by many substances dissolved in water. Excessive content of organic substances in the water changes the color of the water to yellowish or greenish, gives the water an unpleasant smell and taste. Groundwater contains hydrogen sulfide, gives the water the smell of a rotten egg. When the water stays in the pipeline or well for a long time, various microorganisms start to grow in the water, which can release many bad-smelling substances into the water and change the taste of the water.
Iron content of water from a natural water source or depreciated metal piping. Elevated iron content in drinking water does not pose a health risk, but impairs the organoleptic properties of the water. The high iron content is accompanied by an unpleasant taste and turbidity of the water, a yellowish color of the water and a brown precipitate. The maximum level of iron in drinking water is 0.2 mg / l.
The content of manganese in natural water does not pose a risk to health and its content is regulated to ensure organoleptic properties. Increased manganese content in water is the cause
formation of black sediment on surfaces in contact with water. The maximum level for manganese in drinking water is 0.05 mg / l
Water hardness is caused by the calcium and magnesium content of the water. Calcium and magnesium are important minerals for human health, but they cause limescale and limescale deposits in water. If the water hardness is high, the faucets will become clogged, white stains will remain on the sanitary ware, the consumption of detergent will increase, in boilers and heat exchangers, limescale will form, heat exchange will deteriorate and heating costs will increase.
