Smell, color, turbidity, taste and flavor are organoleptic properties of water; and there are certain organic and chemical substances that impair these properties. In this article, let's talk about exactly what organoleptic contaminants are found in water, where they come from, and how to remove them.
Why water is turbid
Water loses its transparency due to the presence of tiny suspended particles that do not sink to the bottom immediately or do not sink there at all when settling. These particles may be organic or inorganic, otherwise known as fine suspended solids.
In rivers, shallow wells, and wells, turbidity increases during spring snowmelt and rainy seasons. Algae proliferate in rivers and humus and clay are washed down with springtime streams. Humus also finds its way into the water through the joints of well pipes or the collapse of well walls.
If you have cloudy water running from your shower head, we suggest you buy a shower water filter in our store. It perfectly copes with such a problem!
What gives water its color
Water can be both colorless and with shades: white, yellow, brown, green, red, gray. The hue and its intensity depends on the dissolved organic substances and inorganic compounds in the water, as well as on their quantity.
The yellowish or brown color of the water is usually due to clay, humus or peat. If the water is opaque, then the cause may be fine sand, which can be seen in the sediment.
Transparent but bright yellow, green or reddish water is caused by algae and phytoplankton.
If the water initially appears clear, but when settling changes color from yellowish to almost red, it indicates the presence of organic iron, and the more it is, the darker and more intense the color.
When the water has a whitish hue, and it partially precipitates during sedimentation, it is a sign of limestone or white clay.
Why does the water smell bad
The intensity of the smell is determined by a person's sense of smell, and there is a special scale in which the most strongly pronounced smell is indicated by the number 5, and the absence of smell - the number 1. The consumer should know that if he feels the smell not immediately, but only after another person points out its presence, such water has a score of 2 and is still suitable for drinking.
The smell of water comes from various gases, organic and inorganic compounds; it can be of natural or artificial origin.
Water smells of natural origin: swampy, muddy, earthy, putrid, fecal, hydrogen sulfide (smell of rotten eggs). They arise in the process of vital activity of plants and microorganisms, as well as due to the influence on the water of river banks, soils, soil, decaying organics and some agricultural runoff.
Odors of artificial origin: chlorine, iron, phenolic, gasoline. Mostly they arise from the fact that industrial effluents from factories, plants, car washes get into the water. Our Chlorine Shower Head works great against chlorine odors!
What should drinking water taste like?
Ideally, water should either have no taste or it should be mild and not repulsive. There are four tastes: sweet, bitter, sour and salty. For example, water with an excess of sodium, potassium and magnesium tastes brackish. There are also flavors: metallic, chlorine, astringent and others. For example, manganese gives astringent taste to water,
The tastes and flavors of water depend on what gases, chemical and organic compounds are dissolved or suspended in it (undissolved).
Filter pitchers do an excellent job of normalizing the taste!
How to purify water
Most organoleptic contaminants can be removed with one filter, the charcoal filter. Activated carbon inside such filter is an excellent adsorbent: it captures almost all organics, as well as chlorine and petroleum products. After the charcoal filter water gets rid of odors, becomes clear and pleasant to the taste.
If the cause of turbidity and color is organic iron, it can be removed by the treatment system, which will include a filter that removes iron. The de-ironer also removes manganese and hydrogen sulfide.
Turbidity and chromaticity due to the presence of tiny particles of sand and clay are removed by means of 15 Stage Shower Water Filter.
Limestone, as well as all other organoleptic impurities, is effectively removed by a reverse osmosis system.
When installing a water treatment filter or filter system, it is important to properly size cylinders or cartridges, competently install and maintain water treatment equipment in time!
