4.  A building in which are located and operated the
pumps of an irrigation system.
 Pump houses are facilities including pumps and
equipment for pumping fluids from one place to
another.
 They are used for a variety of infrastructure
systems.

5. Two types of pumping station exist:
 Dry Pumping Station:
Built as a room outside of the water or watertight in
which the pumps are installed functioning in open air.

6.  Flooded or Wet Pumping Station:
Built as a reservoir , in which submersible or vertical
pumps are installed.

7. The design of a pumping station should take into
account the following parameters:
 Type of pumps chosen
 Maximum water flow required to supply the
hatchery at any time
 Preferred schedule of utilization of the pumps.
 Different water flows required during the annual
production cycle.
 Hydraulic conditions under which the pumps
operate.

8.  Distributing water in the hatchery
 Draining water from the hatchery
 Air supply

9. Air supply means
distribution of air. The
process of air supply in
hatchery is an essential. A
vigorous supply of air in
all tanks of larvae,
Artemia culture, mixing
storage to keep to keep
dissolved oxygen level
high.

10. In the larval tanks air needs to be well distributed,
because its not only keep the oxygen level in the
whole tank but also keep the larvae a close contract
to their food.so that they can easily get food.
Some hatcheries air is distributed through several
rigid of 0.5-10imch(1.25-2. 5cm)diameter PVC pipe
with holes buy cut into them at 0.3-0.5m intervals
with a 1/32drills.

11. Others use weighted flexible
plastic tubing laid on the
bottom of the tank, with hole
punctured in them, but its
has some problems like the
holes in pipes and flexible
tubing become blocked,
besides pipes or tubing on
the tank bottom hide
detritus which provided a
favorable condition for the
growth of fungi and
protozoa and making
difficult to clean the tank.
However the use of good
quality stone is preferable
for this.

13.  Power house means an organization that produces a
lot of ideas or activity , and has a lot of power or
influence in its field.
 In another word , it is a person who is very strong
and has a lot of energy.
 In fact , power house is an electrical generating
station or plant.

14.  The most essential equipment to generate electricity
is the ‘Turbine’ . There is a turbine which has the
power of rotation and through this rotation power or
electricity is produced which is then provided to our
locality.

15.  Conventional Sources
• Thermal power
• Hydro power
• Nuclear power
 Non –conventional Sources
• Wind power
• Solar power
• Biomass power
• Tidal wave energy
• Geo thermal energy.

16.  Thermal power:
 Hydro power:

17.  Nuclear power plant:
 Wind power house:

18.  Tidal wave energy:
 Geo thermal energy:

19. Uses of Electricity in Hatchery
 Electricity is essential to provide the necessary power to run
equipment.
 For running the pump
 For water supply and water treatment
 For starting algal cultures etc.
So, installation of a stand by generator is absolutely
necessary especially in area where there are frequent
and/or lengthy power failures and fluctuation.

20.  Ensure that a certified electrical supplier checks and
approves the system.
 Check the power supply backup system regularly.
 Provide automatically fused control boxes for each
item of equipment.
 Select hatchery equipment with energy saving
features.
 Ensures that the system has sufficient capacity for
future expansion.

21. Degassing

22. “Degassing”
Degassing is the removal of organic gases from the
stationary tanks, containers or pipelines. Or, A degasser
is a device used in drilling to remove gasses from drilling
fluid which could otherwise form bubbles.
Degasser
For a small amount of entrained gas in a drilling fluid, the
degasser can play a major role of removing small bubbles
that a liquid film has enveloped and break out the air and
gas such as methane, H2s and CO2 from the mud to the
surface, the drilling fluid must pas degassing technique
and it can be accomplished by the equipment called
degasser which is also a major part of a mud systems.

23. Atmospheric Degasser
This type of degasser processes mud by accelerating fluid through a
submerged pump impeller and impinging the fluid on a stationary
baffles to maximize surface and thus enable escaping gas vent
atmosphere.
Atmospheric Degasser

24. Vacuum Tank Degasser
Vacuum type is the most common form
of degasser. It can be horizontal, vertical
or round vessel. A vacuum action is
created to pull in the gas cut mud. When
the liquid enters the tank it will flow and
be distributed to a layer of internal
baffle plates designed for the mud to
flow in thin laminar film and is exposed
to a vacuum that forces the gas to
escape and break out of the mud. The
vacuum pump moves the escaping gas
from the vessel discharging it to the
rig’s flare environmental control system.

25. Effluent Treatment Plant

26. Effluent Treatment Plant
ETP is one type of waste water treatment method which
is particularly designed to purify industrial waste water for its
reuse and it’s aim is to release safe water to environment from
the harmful effect.
• Industrial effluents contain various materials, depending on
the industry.
• Some effluents contain oils and grease, and some contain
toxic.
• The ETP Plant works at various levels and involves various
physical, chemical, biological and membrane processes to
treat waste water from different industrial sectors like
chemicals, drugs, pharmaceutical, refineries, dairy, ready mix
plants & textile etc.

27. Effluent Treatment Process
The treatment of different effluents varies with the
type of effluent. Wastewater enters the effluent or sewage
treatment plant and goes through several processes before
effluent goes into the Hatchery. Effluent treatment plant
process include the following stages:
• Primary Treatment
• Biological Treatment
• Advanced/Disinfection Treatment

28. Primary Treatment
 Screening:
• This is the first unit operation
• Its purpose is to remove large floating solids.
 Sedimentation:
• It is a physical water treatment process.
• Using gravitational force to remove suspended solids from water.
 Grit Chamber:
• The wastewater moves into the grit chamber and removes the
dense inorganic solids such as gravel, metal fragments and sand.
• Removal of grit can prevent damaging of pumps & operational
difficulties.
 Neutralization:
• The main purpose of this process helps in maintaining the pH
range of 6-9 to meet the requirements of different processing
units in ETP system.

29. Biological Treatment
Using Bio-filter, it release the high quality water into the
next step of treatment. It helps to
• Remove bacteria and microbes
• Remove ammonia
• Remove nitrites
• Remove dissolved organic solids
• Add oxygen
• Remove carbon dioxide
• Remove excess nitrogen and other dissolved gasses
• Remove suspended solids

30. Advanced/Disinfection Treatment
UV Disinfection:
• It is considered as an ideal disinfectant.
• It leaves no residual disinfectant in the water by ensuring the
water quality.
• It does not produce any disinfection by-products.
Benefits of ETP:
• To clean industry effluent and recycle it for further use
• To preserve natural environment against pollution.
• To meet the standards for emission of pollutants set by the
Government & avoid heavy penalty.
• Reduce cost for marine fish hatchery by reuse of water.
