Tannins are a type of organic molecule produced by the decomposition of plants. Tannins are commonly found in surface water sources and shallow wells below sea level, as well as aquatic and coastal environments. Water moving through areas with a lot of rotting vegetation collects these minute plant particles, which gives the river its color. This coloration is sometimes mistaken for debris or impurities, although it's actually tannins in the water.In drinking water, tannins can leave a vinegary or sour aftertaste. Individuals may also detect a moldy or lemony odor in the water. Tannins in water are considered an aesthetic problem. Even though they can make water unfit for drinking and stain clothes, they offer no health risk.Tannins can have the same effect on private well water. On its way down to the reservoir that supports your well, ground water may pass through rotting plants or tannic soil.
Tannins are biological chemicals that are produced naturally as a result of decaying plant life and water passing through peaty soil. This can cause water to turn a hazy yellow to a tea-like tint, as well as yellow discoloration on materials.When consumed or used in the home, tannins in water pose minor health or safety dangers, but they may produce certain unusual problems. Apart from their ugly look, tannins in water can have a damp, crop-like stench and a strangely bitter aftertaste when consumed. The amber color has the power to discolor laundry for a long time and acts as a dye.Basically, the most serious problem with this simple contaminant is that, it will alter the flavor, look, and smell of water due to the formation of tiny, organic humic acid molecules in the water.
Nobody wants to wash clothes in dirty water, especially because it is known to discolor clothes. Similarly, drinking water that is murky or tea-like, smells awful, and tastes sour, is probably not your idea of fun. The water-based units in your home are at risk of lasting harm due to tannin molecules generating fouling and staining.
HOW CAN NETSOL HELP IN REMOVING TANNINS FROM WATER?
·While the water treatment business is expanding, removing tannins from water can still be a challenge. In one place, a water purifying process may be effective, while completely ineffective in another. The success of treatment approaches is usually determined by the vegetation in a given location.
·When it comes to eliminating tannins from drinking water, ION EXCHANGE systems are the most effective water treatment technology. To get the most out of ion exchange systems and keep them from fouling or scaling, adequate pretreatment is required.
·Water softening, media filters, UV sterilizers, and ultrafiltration are all examples of pretreatment procedures that increase the life of the ion exchange system while also improving tannin absorption. Regeneration measures such as adding salt water solutions and baking soda should also be used to improve the effectiveness of the ion exchange system. When cleaning is required, the fouling ion exchange resin produces a fishy odor in the water.
·REVERSE OSMOSIS systems are also used to remove tannins from water as supplementary treatments or polishers. The efficiency of reverse osmosis is primarily due to the fact that tannins are organic molecules with a high molecular weight. Regardless of this fact, tannins in water can be hazardous to reverse osmosis systems, as they have a tendency to clog the membrane. Another advantage of the reverse osmosis method is that if the qualities of the supply water change, the RO system will be able to handle it.
·The final treatment option is OXIDATION, which is less straightforward than ion exchange systems. Chlorine is one of several effective oxidation agents for eliminating tannins from water. A simple jar test can be used to determine the concentration and retention duration for optimal tannin oxidation of feed water. Tannin levels in water can also be reduced to acceptable levels using certain types of activated carbon units.
