Filter Air Softener 24x72 In FRP Manual

This is also often found as the same crust on the inner surface of old pipes and other surfaces where & ldquo; hard water & rdquo; has evaporated.), which can make pipe rot, and galvanic corrosion. & Nbsp; However, hard water can also provide some health benefits by providing calcium and magnesium and reducing the potential for toxic potential from the metal ions and copper.

The method used generally relies on the method of removing Ca2 + and Mg2 + from the solution or absorption of this ion, the process used is binding them to a molecule that eliminates their ability to form a scale or disturb detergents. This deletion is achieved by the exchange of ions and with the precipitation method. Absorption requires the addition of chemical compounds called agents of absorption (or chelating).

Since Ca2 + and Mg2 + exist as flying salt (light ions), they can be removed by refining water, but distillation is too expensive in most cases of hard water, so use more distilled processes.

Sodium ion exchange material contains ions (Na +) that are bound and electrostatic that are ready to be replaced by violent ions such as Ca2 +and Mg2 +. & Nbsp; Exchange of organic polymer resin ions containing an anionic functional groups that are bound. Minerals called zeolites also show the nature of ion exchange, this mineral is widely used in detergent.

Water must be treated through a resin filter. Negatively charged resins will absorb and bind positively charged metal ions. Resin initially contains univalent (1 +) ions, most often sodium, but sometimes also hydrogen (H +) or potassium (K +). Divalent calcium and magnesium ions in water replace this ion into univalent, which is released into the water. The & ldquo; hard & rdquo; water (hard water), more hydrogen, sodium or potassium ions released from resin and enter water.

Resin is also available to remove carbonate ions, bi-carbonate and sulfate absorbed and hydroxyl ions released from the resin. Both types of resins can provide a single water softening effect.

regeneration process
The resin capacity will gradually reach the point of fatigue (saturated) and eventually only contain divalent ions, mg2 + and Ca2 + for cation exchange resins, and SO42 anion resins for exchange. At this stage, resin must be regenerated. If cationic resins are used (to remove calcium and magnesium ions), regeneration is usually done by passing concentrated salt water, usually sodium chloride or potassium chloride, or chloride acid solution. For anionic resin, regeneration usually uses sodium hydroxide solution or potassium hydroxide. On an industrial scale, the flow of effluent waste from the re-generation disposal process can trigger a value scale that can interfere with the waste disposal system.

The impact of hard water (hard water) for human health

sodium sodium effect
For people in the low sodium diet, increased levels of sodium in water can be significant, especially when caring for very hard water. For example:

Someone who drinks two liters (2L) from water included in soft water (assume receiving 30 gpg intake), then with the same dose and using hard water is expected to consume around 480 mg of more sodium (2l x 30 gpg x 8 mg / l / GPG = 480 mg). This comparison is very visible, the difference is very far.

The American Heart Association (AHA) shows that at least 3 percent of the current population still consumes the amount of the weight of the specified salt, where the amount of salt consumed is not more than 400 mg of sodium per day. & Nbsp; AHA shows that no more than 10 percent of sodium intake comes from water. & Nbsp; Draft Guidelines for EPA 20 mg/L for water Protects the most vulnerable people.

Most people who care about sodium levels in water generally have one of the faucets in homes that use water soffts (water softener), or have reverse osmosis & nbsp; The system installed for drinking water and cooking water, which is designed for desalinisation of sea water.

potassium chloride can indeed be used as a substitute for sodium chloride, which has additional benefits to help lower blood pressure, but it is very expensive. But even in this way it must be done carefully because of high potassium levels that are dangerous and can cause complications such as cardiac arrhythmia, although people with normal kidney function must consume large amounts of potassium to develop hypercalemia.
