IMPORTANT :
- Raw Water Should Be Free From Turbidity, Free Chlorine, Heavy Metal,
Organic Matter, Oil and Should Be At Ambient Temperature
- Out put per generation is depend on effluent water quality
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 degasifier 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
degasifier 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
anionexchanger 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.coil 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. candys
filter ) both the type are in use the following steps are involved in the
purification of water by rapid sand filter
- 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
- 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.
- 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.
- 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
- 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 sandbed 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:
- rapid send filter can deal with raw water directly no preliminary
storage is needed
- the filter beds occupy less space
- filtration is rapid, 40-50 time that of a slow sand filter
- the washing of the filter is easy
- there is more flexibility in operation.

What is Ozone?
- Ozone is triatomatic 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,
disinfective, deodorizing decolorizing and oxidizing capacity.
- Ozone is 1.5 time stronger oxidant and 3000 time fastest disinfectant
than chlorine
- Ozone is also has microfloculent property which gives sparkle and
crystal clear clarity to water
