Q13. Why is water quality in closed systems important?
  Closed water systems are carefully designed to create precise and adaptable environmental conditions within buildings or process plant. The design necessitates the use of small bore control and regulating valves. If corrosion debris, installation debris or microbes are present these orifices may become blocked or restricted and the system will not operate to design parameters. Ultimately if systems are not cared for the pipe work and fittings may fail prematurely due to corrosion and other contributory factors. Water quality and water treatment are therefore very important.
Q14. What is industrial water treatment?
  Industrial Water Treatment can be classified into the following categories:
  * Boiler water treatment
  * Cooling water treatment
  * Wastewater treatment
  Water treatment is used to optimize most water-based industrial processes, such as: heating, cooling, processing, cleaning, and rinsing, so that operating costs and risks are reduced. Poor water treatment lets water interact with the surfaces of pipes and vessels which contain it. Steam boilers can scale up or corrode, and these deposits will mean more fuel is needed to heat the same amount of water. Cooling towers can also scale up and corrode, but left untreated, the warm, dirty water they can contain will encourage bacteria to grow, and Legionnaires' Disease can be the fatal consequence. In many cases, effluent water from one process might be perfectly suitable for reuse in another process somewhere else on site. With the proper treatment, a significant proportion of industrial on-site wastewater might be reusable. This can save money in three ways: lower charges for lower water consumption, lower charges for the smaller volume of effluent water discharged and lower energy costs due to the recovery of heat in recycled wastewater.
Q15. What is hard water?
  When water is referred to as 'hard' this simply means, that it contains more minerals than ordinary water. These are especially the minerals calcium and magnesium. The degree of hardness of the water increases, when more calcium and magnesium dissolve. Water with hardness more than 5 ppm is considered as hard.
  Magnesium and calcium are positively charged ions. Because of their presence, other positively charged ions will dissolve less easily in hard water than in water that does not contain calcium and magnesium. This is the cause of the fact that soap doesn't really dissolve in hard water.
Q16. What are hard water minerals?
  Calcium, manganese and magnesium are the most common minerals.
Q17. What are the hard water problems?
  Hard water causes scale to build up in pipes, heat exchanger, cooling tower and many other hot water systems. These scale deposits lead to lower cooling efficiencies, increased power consumption and lowering the life of mother plant.
Q18. What are the objectives of industrial water treatment?
  Industrial water treatment seeks to manage four main problem areas: scaling, corrosion, microbiological activity and disposal of residual waste water. Boilers do not have many problems with microbes as the high temperature prevents their growth.
  Scaling occurs when the chemistry and temperature conditions are such that the dissolved mineral salts in the water are caused to precipitate and form solid deposits. These can be mobile, like a fine silt, or can build up in layers on the metal surfaces of the systems. Scale is a problem because it insulates and heat exchange becomes less efficient as the scale thickens, which wastes energy. Scale also narrows pipe widths and therefore increases the energy used in pumping the water through the pipes.
  Corrosion occurs when the parent metal oxidises (as iron rusts, for example) and gradually the integrity of the plant equipment is compromised. The corrosion products can cause similar problems to scale, but corrosion can also lead to leaks, which in a pressurized system can lead to catastrophic failures.
  Microbes can thrive in untreated cooling water, which is warm and sometimes full of organic nutrients, as wet cooling towers are very efficient air scrubbers. Dust, flies, grass, fungal spores and so on collect in the water and create a sort of "microbial soup" if not treated with biocides. Most outbreaks of the deadly Legionnaires' Disease have been traced to unmanaged cooling towers, and many country have had stringent Health & Safety guidelines concerning cooling tower operations for many years.
  Disposal of residual wastewaters from an industrial plant is a difficult and costly problem. Most petroleum refineries, chemical and petrochemical plants have onsite facilities to treat their wastewaters so that the pollutant concentrations in the treated wastewater comply with the local and/or national regulations regarding disposal of wastewaters into community treatment plants or into rivers, lakes or oceans.
Q19. What is scale or scaling process?
  It has known that these two salts, calcium and magnesium are responsible for much of scale because they precipitate out of water more readily than other minerals such as sodium salts. These precipitates are held in aqueous suspension and when subjected to the normal temperature changes and pressure changes which accelerates the clustering of these suspended molecules. When the cluster achieves a size larger than that which can be maintained in suspension, the scaling process is initiated. In a pipe or tubing, the fluid velocity is greater in the center than close to the wall. The natural tendency for scale deposits to form is where the velocity of the fluid is lower so scale forms on the wall of pipes and lower velocity surfaces of heat exchangers for these reasons.
Q20. What is de-scaling?
  Removal of lime scale deposits from pipe lines, cooling towers, heat exchangers etc. with the help of de-scaling agents. Descaling agents usually contain an acid as the active ingredient, e.g. acetic acid, lactic acid, citric acid, phosphoric acid, hydrochloric acid, or sulfuric acid.
Q21. What is water softening?
  When water contains a significant amount of calcium and magnesium, it is called hard water. Hard water is known to clog pipes and to complicate soap and detergent dissolving in water.
  Water softening is a technique that serves the removal of the ions that cause the water to be hard, in most cases calcium and magnesium ions. Iron ions may also be removed during softening.
  Most conventional water softening devices depend on a process known as ion-exchange in which "hardness" ions trade places with sodium and chloride ions that are loosely bound to an ion exchange resin orazeolite (Many zeolite minerals occur in nature, but specialized one are often made artificially.
Q22. What is a water softener?
  A water softener is a unit that is used to soften water, by removing the minerals that cause the water to be hard.
  Water softeners are specific ion exchangers that are designed to remove ions, which are positively charged.
  Softeners mainly remove calcium (Ca2+) and magnesium (Mg2+) ions. Calcium and magnesium are often referred to as 'hardness minerals'. Softeners are sometimes even applied to remove iron. The softening devices are able to remove up to five milligrams per liter (5 mg/L) of dissolved iron. Softeners can operate automatic, semi-automatic, or manual. Each type is rated on the amount of hardness it can remove before regeneration is necessary.
  A water softener collects hardness minerals within its conditioning tank and from time to time flushes them away to drain.
  Ion exchangers are often used for water softening. When an ion exchanger is applied for water softening, it will replace the calcium and magnesium ions in the water with other ions, for instance sodium or potassium. The exchanger ions are added to the ion exchanger reservoir as sodium and potassium salts (NaCl and KCl).
Q23. What is reverse osmosis?
  Reverse osmosis (RO) is a separation process that uses pressure to force a solution through a membrane that retains the solute on one side and allows the pure solvent to pass to the other side. More formally, it is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. This is the reverse of the normal osmosis process, which is the natural movement of solvent from an area of low solute concentration, through a membrane, to an area of high solute concentration when no external pressure is applied. The membrane here is semi permeable, meaning it allows the passage of solvent but not of solute.
  The membranes used for reverse osmosis have a dense barrier layer in the polymer matrix where most separation occurs. In most cases the membrane is designed to allow only water to pass through this dense layer while preventing the passage of solutes (such as salt ions). This process requires that a high pressure be exerted on the high concentration side of the membrane, usually 2-17 bar (30-250 psi) for fresh and brackish water, and 40-70 bar (600-1000 psi) for seawater, which has around 24 bar (350 psi) natural osmotic pressure which must be overcome.
