Demineralisationis the process of removing mineral salts from water by using the ion exchange process.

Demineralised water also known as De-ionised water. Deionisation is a physical process which usesion exchange resins which provides ion exchange site for the replacement of the mineral salts in water with water forming H+ and OH- ions. Because the majority of water impurities are dissolved salts, deionisation produces a high purity water that is generally similar to distilled water, and this process is quick and without scale build up.
De-mineralization technology is the proven process for treatment of water. A D.M. Water System produces mineral free water by operating on the principles of ion exchange, Degasification, and polishing. Demineralised Water System finds wide application in the field of steam, power, process, and cooling.

Principle :

Raw water is passed via two bed filled (ion exchange resins). While the cations get exchanged with hydrogen ions in first bed, the anions are exchanged with hydroxyl ions, in the second one.

Process :

Ion-exchange is a rapid and reversible process in which impure ions present in the water are replaced by ions released by an ion-exchange resin. The impure ions are taken up by the resin, which must be periodically regenerated to restore it to the original ionic form.

Ion Exchange Resins :

There are two basic types of resin - cation-exchange and anion-exchange resins. Cation exchange resins will release Hydrogen (H+) ions or other positively charged ions in exchange for impurity cations present in the water. Anion exchange resins will release hydroxyl (OH-) ions or other negatively charged ions in exchange for impurity anions present in the water.

There are three ways in which ion-exchange technology can be used in water treatment and purification

1.Cation-exchange resins alone can be used to soften water by base exchange.

2.Anion-exchange resins alone can be used for organic adsorption or nitrate removal.

3.Andcombinations of cation-exchange and anion-exchange resins can be used to remove virtually all the ionic impurities present in the feed water, a process known as deionisation. Water deionizers purification process results in water of exceptionally high quality

De-Mineralisation / De-ionisation :

For many industrial applications, high-purity water is essentially free from ionic contaminants is required. Water of this quality can be produced by deionisation. The two most common types of deionization are :

Two-bed deionization

Mixed-bed deionization

Two bed de-ionisation :

The two-bed deionizer consists of two vessels - one containing a cation-exchange resin in the hydrogen (H+) form and the other containing an anion resin in the hydroxyl (OH-) form. Water flows through the cation column, whereupon all the cations are exchanged for hydrogen ions. The same principle applies when considering anion-exchange.

The de-cationised water then flows through the anion column. This time, all the negatively charged ions are exchanged for hydroxide ions which then combine with the hydrogen ions to form water (H2O).

Mix bed (MB) de-ionisation :

In mixed-bed deionizers the cation-exchange and anion-exchange resins are intimately mixed and contained in a single pressure vessel. The thorough mixture of cation-exchangers and anion-exchangers in a single column makes a mixed-bed deionizer equivalent to a lengthy series of two-bed plants. As a result, the water quality obtained from a mixed-bed deionizer is appreciably higher than that produced by a two-bedplant.
Although more efficient in purifying the incoming feed water, mixed-bed plants are more sensitive to impurities in the water supply and involve a more complicated regeneration process. Mixed-bed deionisers are normally used to polish the water to higher levels of purity after it has been initially treated by either a two-bed deionizer or a reverse osmosis unit.Mixed bed polishing produces a water with less than0.1micro Siemens per centimetreconductivity. With sophisticated design and appropriate resins, the conductivity of pure water (0.055micro Siemens per centimetre) can be achieved. Residual silica values can be as low as 1micro Siemens per centimetre

Water softeningis the removal ofcalcium, magnesium, and certain other metalcationsinhard water. The resulting soft water is more compatible with soap and extends the lifetime of scaling and deposition problem. Water softening is usually achieved usinglime softeningorion-exchange resins.

Ion-exchange resin devices

Conventional water-softening equipment installed for industrial use depends on anion-exchange resinin which "hardness ions" - mainly Ca2+and Mg2+- are exchanged forsodiumions. Ion exchange devices reduce the hardness by replacing magnesium and calcium (Mg2+and Ca2+) with sodium or potassium ions (Na+and K+)."

Ion Exchange-Principle

Ion Exchange resins are insoluble granular substances which have in their molecular structure acidic or basic radicals that can be exchanged. The positive or negative ions fixed on these radicals are replaced by ions of the same sign in solution in the liquid in contact with them.

Ion Exchanger-Reaction

Ion Exchangers are insoluble granular substances which have in their molecular structure acidic or basic radicals that can exchange. The positive or negative ions fixed on these radicals are replaced by ions of the same sign in solution in the liquid in contact with them.

Strong Acid Cation (SAC) exchange resin in the sodium (Na+) form where the hardness ions of calcium (Ca+2) and magnesium (Mg+2) are exchanged for more soluble sodium ions. The general reactions for calcium are shown here:

This reaction is reversible and upon exhaustion, the resin can be returned to the sodium form through regeneration, contacting it with an excess of sodium chloride (NaCl).

he treatment of water for steam generation is one of the most significant branches of water chemistry. Industries use steam, either in the process or generating power. Generation of steam is energy intensive and costly, therefore efficient production and utilization of steam is a prerequisite to keep over all cost of production down. Strategy for the boiler water treatment should be to use the boiler that operates with the highest efficiency for the longest possible timeBoiler water should be treated properly to prevent pittingcorrosion, scaling and carryover even hot blast of tubes. Using some of the specific result oriented additives can prevent these problems to facilitate fast, safe & reliable steam generation.

What are the sources of iron and manganese in water.

Iron and manganese are concentrated in water by contact with rocks and minerals, and occasionally fabricated materials like iron and steel pipes. Groundwater supplies may require treatment for high levels of iron and manganese; generally few surface water supplies have high enough levels of either to cause problems. Occasionally discharge of acid industrial wastes or mine drainage may increase iron or manganese to problem levels in surface water.

What problems are caused by iron and manganese?

Neither iron nor manganese in water present a health hazard. However, their presence in water may cause taste, staining and accumulation problems.

Because iron and manganese are chemically similar, they cause similar problems. Iron will cause reddish-brown staining of laundry, porcelain, dishes, utensils and even glassware. Manganese acts in a similar way but causes a brownish-black stain. Soaps and detergents do not remove these stains, and the use of chlorine bleach and alkaline builders (such as sodium carbonate) can actually intensify the stains.

Iron and manganese deposits will build up in pipelines, pressure tanks, water heaters and water softeners. This reduces the available quantity and pressure of the water supply. Iron and manganese accumulations become an economic problem when water supply or softening equipment must be replaced. Also, pumping water through constricted pipes or heating water with heating rods coated with iron or manganese minerals increase energy costs.

the redox potential of the water is such as it allows an oxidation of the ferrous iron in ferric iron which precipitates then in iron hydroxide, Fe(OH)3, thus allowing a natural removal of dissolved iron.

Boilers are systems which generate steam, which consists of two principal parts: the furnace, which provides heat, usually by burning a fuel, and the Boiler proper, a device in which the heat changes water into steam. The steam or hot fluid is then recirculated out of the boiler for use in various processes for heating applications.

Proper pre-treatment of Boiler feed water is an important part of operating and maintaining a boiler system. As steam is produced, dissolved solids become concentrated and form deposits inside the boiler. This leads to poor heat transfer and reduces the efficiency of the boiler. Dissolved gasses such as oxygen and carbon dioxide will react with the metals in the boiler system and lead to boiler corrosion. In order to protect the boiler from these contaminants, they should be eliminated or at least through external or internal treatment.

Reverse Osmosis (RO) is a modern process to purify water for a wide range of applications, including semiconductors, boiler feed water treatment, food processing, biotechnology, pharmaceuticals, power generation, seawater desalting, and municipal drinking water.

This particular process uses a weakly acidic cation resin. This resin type is capable of removing hardness from water when it also contains alkalinity. After treatment, the water contains carbon dioxide, that can be eliminated with adegasifier tower. The cation resin is very efficiently regenerated with an acid, usually hydrochloric acid.

Reactions

Here the example of calcium:

2 R-H + Ca++(HCO3)2R2-Ca + 2 H++ 2 HCO3

and the hydrogen cations combine with the birarbonate anions to produce carbon dioxide and water:

H++ HCO3CO2+ H2O

The salinity has decreased. Temporary hardness is gone.

De-alkalisation is used:

In breweries

In household drinking water filters

For low pressure boilers

For cooling Tower

As a first step before the SAC exchange in demineralisation

Benefits:

Reduce Blowdown - Alkalinity is a factor that most often dictates the amount of boiler blowdown. High alkalinity promotes boiler foaming and carryover and causes high amounts of boiler blowoff. When alkalinity is the limiting factor affecting the amount of blowdown, a dealkalizer will increase the cycles of concentrations, reducing blowdown and lowering operating costs.

Reduce Chemical Use - The reduction of blowdown by dealkalization keeps the water treatment chemicals in the boiler longer, thus minimizing the amount of chemicals required for efficient, non-corrosive operation.

Reduce Return Line Corrosion - Carbonate and bicarbonate alkalinities are decomposed by heat in boiler water, releasing carbon dioxide into the steam. This gas combines with the condensed steam in process equipment and return lines to form carbonic acid (H2CO3). This depresses the pH value of the condensate returns and results in corrosive attack on the equipment and piping.

Improve Textile Dyeing - Alkalinity may also produce non-uniform results in dyeing of textiles and other fabrics because of its effect on the pH value of the dye bath.

Improve Beverage Tastes - In beverage manufacturing, alkalinity often produces flat tastes or tends to destroy taste characteristics of flavoring extracts.

Sand filtrationis a frequently used very robust method to remove suspended solids from water.The filtration medium consists of a multiple layer of sand with a variety in size and specific gravity.

A sand filter has a Highdirt holding capacityTSS / m2 of sand surface.

When the filters are loaded with particles, the flow direction is reversed and the flow is increased to clean the filter again . This step is called a backwash.

Carbon filteris a method of filtering that uses a bed ofactivated carbonto remove contaminants and impurities, using chemicalabsorption.

Each particle/granule of carbon provides a large surface area/pore structure, allowing contaminants the maximum possible exposure to the active sites within the filter media. One pound (450 g) of activated carbon contains a surface area of approximately 100 acres (40 Hectares).
