De Mineralized water treatment plant (D.M. PLANT) :

Process :

Demineralization systems are very widely employed not only for conditioning water for high – pressure boilers but also for conditioning various process and rinse water the ion – exchange system chosen very accordingly to the volumes and composition of the raw waters, the effluent- quality require for different uses and the comparative capital and operation cost briefly if silica removal is not require the system may consist of a hydrogen – cation – exchanger unit and a weekly basic anion exchanger unit usually followed by a de gasifier to remove by aeration most of the carbon dioxide formed from the bicarbonates in the first step when silica removal basic anion – exchanger unit usually with a de gasifier between the unit to removed carbon dioxide ahead of the strongly basic anion –exchanger unit for uses where the very highest quality of effluent is required this may be followed by secondary polishing unit consisting of either.

A hydrogen – cation – exchanger unit and a strongly basic anion–exchanger unit or

A single unit containing an intimately mixed bed of a hydrogen cation – exchanger and a strongly basic anion exchanger

Pressure Sand filter :

Process :

The filter is equipped with certain valves and device which are incorporated in the outlet –pipe system the propose of the device is to maintain a constant rate of filtration an important components of the regulation system is the venture mater which meager the bad resistant or loss of head when the resistant built up the operator open the regulation valves so as to maintain a steady rate of filtration when the loss of head exceed 1.3 meter it is uneconomical to run the filter.

Normally the filter may run weeks or even month without cleaning when the bed resistant increase to such an extant that the regulation valves has to be kept fully open it is time to clean the filter bed since any further increase is drained off and the sand bed is clean by scraping of the top portion of the sand layer to a depth of 1 or 2 cm this operation may be carried out by unskilled laborers using hand tool or by mechanical equipment after several year of operation and say 20 or 30 scraping the thickness of the sand bed will have reduced to about 0.5 to 0.8 meter then the plant is closed down and a new bed is constructed.

The advantages of a slow sand filter are 1) simple to construction and operation 2) the cost of construction cheaper than that of rapid sand filters 3) the physical chemical and bacteriological quality of filter water is very high when working ideally, slow sand filter have been shown to reduce total bacterial counts by 99.9 to 99.9 per cent and E.coli by 99to 99.9 per cent

In recent year a mistaken idea has grown that biological or slow sand filtration is an old fashioned outdated method of water treatment which has been completely superseded by rapid sand filtration this is defiantly not the case slow sand filtration is still the chosen method of water purification in a number of high industrialized cities as well as urban areas in a number of cities in U.S and Europe slow sand filters have recently been constructed.

Rapid Sand or Mechanical Filter :

In 1885 the first rapid sand filer were installed in the USA since that time they have gained considerable popularity especially in high industrialized countries.

Rapid sand filter are of two type the gravity type (e.g. candy’s filter ) both the type are in use the following steps are involved in the purification of water by rapid sand filter

1.    Coagulation: the raw water is first treated with a chemical coagulant such as alum the dose of which varies from 5 – 40 mg or more per liter depending upon the turbidity and colors temperature and the ph value of the water

2.    Rapid mixing: the treated water is then subject to violent agitation in a mixing chamber for a few minutes this allows is quick and thorough dissemination of alum throughout the bulk of the water which is very necessary.

3.    Flocculation the next phase involve a slow and gentle stirring of the treated water in a flocculation chamber for about 30 minutes the mechanical type of flocculator is the most widely used it consist of a number of peddles rotate with the help of motor this slow and gentle stirring result in the formation of the thicker the precipitate of rock diameter the greater the setting velocity.

4.    Sedimentation: the coagulated water is now lead sedimentation tanks where it is detained for periods varying from 2-6 hour when the flocculent precipitate together with the impurities and bacteria settle down in the tank at least 95 percentage of the flocculent precipitate needs to be removed before the water is admitted into thee rapid send filter the precipitate or sludge which settle at the bottom ass removed to time without disturbing the operation of the tank for proper maintenance the tank should be clean regularly from time to time otherwise they may become a breeding ground for mollusks and sponge

5.    Filtration: they partly clarified water is now subjected to rapid and sponges

Filter Beds :

Each unit of filter bed has a surface of about 800 to 90 m2 (about 900 sq. feet) Sand is the filtering medium the depth of the sand is the filtering medium the effective size of the send particles is between 0.4-0.7 mm the depth of the sand bed is usually about meter (2 ½ to 3 feet). Bellow the send bed is a layer of graded level 30 to 40 cm ( 1-1 ½ feet deep the gravel support the send bed and permits the filtered water to move freely towards the under drain the depth of the water on the top on the sand bed collect the filtered water rate of filtration is 5-15 m3/m3 hour

Filtration :

As filtration processed , the alum flock not remove by sedimentation is held back on the sand bed it forms a slimy layer comparable to the zoo Leal layer is the slow send filter is it adsorbs bacterial from the water and effect purification oxidation of ammonia also takes place during the passage of water through the filters. as filtration proceeds, the suspended impurities and bacteria clog the filters the filters soon become dirty and begin to lose their efficiency when the loss of head approaches 7-8 feet filtration is stopped and the filters are subjected to a washing process known as back washing

Back-washing :

Rapid send filters need frequent washing daily or depending upon the loss of head washing is accomplished by reversing the water through the sand bed which is called “back washing” back washing dislodge the impurities and cleans up the sand bed the washing is stopped when clear sand is visible and the wash water is sufficient clear the whole process of washing takes about 15 minutes in some rapid sand filters compressor air is used as part of the back washing processes.

Advantages :

The advantage of a rapid sand filter over the slow sand filter is:

1.    rapid send filter can deal with raw water directly no preliminary storage is needed

2.    the filter beds occupy less space

3.    filtration is rapid, 40-50 time that of a slow sand filter

4.    the washing of the filter is easy

5.    there is more flexibility in operation.

What is ozone?

Ozone is triatomic allotrope of oxygen formed by recombination of oxygen atoms

Ozone is a color less gas with a characteristic pun get odor

Ozone is one and half time as heavy as oxygen

Ozone is 12.5 times more soluble in water than oxygen

Ozone has the strongest bactericidal, microbicidal, germicidal, disincentive, deodorizing decolorizing and oxidizing capacity.

Ozone is 1.5 time stronger oxidant and 3000 time fastest disinfectant than chlorine

Ozone is also has micro flocculant property which gives sparkle and crystal clear clarity to water

Ozone reduce it self to oxygen with in 20 min at room –temperature leaving behind a nascent oxygen atom which is a very powerful oxidizing agent

Ozone treatment is absolutely chemical free as it makes use as chlorine fluorine or for my lene redundant

How is ozone produced?

In stratosphere ozone is produced by sun’s ultra violet rays and by lightening

Ozone technology produced ozone (O3) directly from ambient air without any need for oxygen cylinder or chemical

Ozone can proudly proclaim that the unique novel state of the art cold non sparking and indigenously developed technology which sues B1 stages of electronic circuitry can offer maximized production of ozone with economy of scale making it viable to offer customer built machines for each individually need for the first time.

Ozone technology can produce ozone quantity ranging from 1 gm /hr to 180 gms and hence ozone positive air ozonized can purify and sterilize area ranging from 200 sq feet to 25000 sq feet while ozone positive water ozonizes can purify and disinfect ranging from 50 ltr/hr.
