Solapur
Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment. Some industrial facilities generate wastewater that can be treated in sewage treatment plants. Most industrial processes, such as petroleum refineries, chemical and petrochemical plants have their own specialized facilities to treat their wastewaters so that the pollutant concentrations in the treated wastewater comply with the regulations regarding disposal of wastewaters into sewers or into rivers, lakes or oceans.

Maintenance:
Cells use energy and raw materials for two functions, production of new cells and the maintenance of existing cells. In general, consumption of materials for maintenance is small w.r.t. the amount of materials used in the synthesis of new biomass.
Generally it is assumed that the use of materials for maintenance is proportional to the amount of cells present.
The term “fermentation” is derived from the Latin verb fervere, to boil, thus describing the appearance of the action of yeast on extracts of fruit or malted grain. The boiling appearance is due to the production of carbon dioxide bubbles caused by the anaerobic catabolism of the sugars present in the extract. However, fermentation has come to have different meanings to biochemists and to industrial microbiologists. Its biochemical meaning relates to the generation of energy by the catabolism of organic compounds, whereas its meaning in industrial microbiology tends to be much broader. Fermentation is a word that has many meanings for the microbiologist: 1 Any process involving the mass culture of microorganisims, either aerobic or anaerobic. 2 Any biological process that occurs in the absence of O2. 3 Food spoilage. 4 The production of

2. Classifications of Waste Water
Domestic waste waters
These waters are
produced by the mere acts
of living such as using the
bathroom, doing laundry,
or washing the dishes.
3. Classifications of Waste Water
Process waste waters
These waters are produced
by some industrial processes
and include the undesired
liquid product of any unit
operation. The major
concern with these wastes is
the reactions that may occur
with the environment being
either direct or indirect.
Some may rob oxygen from
the environment, while
others may be toxic
4. Industrial Wastes
Industrial Water Pollution
Industrial pollutants that run into streams, rivers, or lakes
can have serious effects on wildlife, plants, and humans. In
the United States there are strict rules for the amount and
composition of substances that factories can release into
bodies of water. These rules are not always enforced, and
much industrial water pollution comes from accidental
chemical or oil spills.
5. Cooling waste waters
These are produced as a result
of heat exchanger where heat
is removed from the product.
Waters can be used once or
recycled.. This type of waste
must also be monitored and
often treated, and is also a
major factor in thermal
pollution of water sources.
6. THERMAL POLLUTION
Thermal Pollution from Power Plants and Factories
Power plants and industrial factories are among the major contributors
to the problem of thermal pollution. These facilities draw water from
nearby lakes and streams, which they use to cool their machinery and
steam-driven equipment. The heated water warms local bodies of
water by as much as 10° C (18° F), making the water uninhabitable
for fish and other organisms.
7. CHARATERISTICS
of Wastewater
PHYSICAL CHARACTERISTICS
•Temperature
•Wide variation in the wastewater temperature indicates
heated or cooled discharges.
•decreased temperatures after a snowmelt or rainfall may
indicate serious infiltration.
•Changes in wastewater temperatures affect the settling rates,
dissolved oxygen levels, and biological action.
•The temperature of wastewater becomes extremely
important in certain wastewater unit operations such as
sedimentation tanks and recirculating filters.
8. Color
The color of wastewater containing dissolved oxygen (DO) is
normally gray. Black-colored wastewater usually accompanied
by foul odors, containing little or no DO, is said to be septic.
Significance of Color in Wastewater
9. oil wastes
domestic wastes
Though the colors are
beautiful, it is full of chemical
wastes.
White color of the
chemical wastes No one is sure exactly Processing timber into
how the ocean will pulp at the mill will result
disperse pollutants, in tons of effluent a day
such as dioxin, from being discharged
the mill
10. Odor
Domestic sewage should have a musty odor. Bubbling gas and/or
foul odor may indicate industrial wastes, anaerobic (septic)
conditions, and operational problems.
Odors in Wastewater Treatment Plant
12. Solids
Wastewater is normally 99.9 % water and 0.1 % solids. If a
wastewater sample is evaporated, the solids remaining are total
solids.
Types Solids:
1. Dissolved solids is an expression for the combined
content of all inorganic and organic substances
contained in a liquid which are present in a
molecular, ionized or micro-granular suspended
form.
Dissolved solids pass through a fine mesh filter.
Normal wastewater processes using settling or
flotation are designed to remove solids but cannot
remove dissolved solids. -
13. Taste/Health: High TDS results in undesirable taste which
could be salty, bitter, or metallic. It could also indicate the
presence of toxic minerals. The EPA's recommended
maximum of TDS in water is 500mg/L (500ppm).
Filter performance : Test your water to make sure the filter
system has a high rejection rate and know when to change
your filter (or membrane) cartridges.
Hardness: High TDS indicates Hard water, which causes scale
buildup in pipes and valves, inhibiting performance.
14. Aquaculture: A constant level of
minerals is necessary for aquatic life.
The water in an aquarium should have
the same levels of TDS and pH as the
fish and reef's original habitat.
Hydroponics: TDS is the best
measurement of the nutrient
concentration in a
hydroponics' solution.
Nutrients for
hydrophonics
15. Pools and Spas: TDS levels must be
monitored to prevent maintenance
problems.
Commercial/Industrial/
Medical: High TDS levels
could impede the
functions of certain
applications generators
Dialysis machine
16. 2. Suspended - This parameter was at one time called non-
filterable residue (NFR), a term that refers to
the identical measurement: the dry-weight of
particles trapped by a filter, typically of a
specified pore size.
3. Settleable or settleable, solids will settle out of water
over time, though this may be so slow that it is
impractical to allow the particles to settle out
in a water treatment plant. The particles are
more than 1,000 Mu in size and can be seen
with a microscope or, sometimes, with the
naked eye. Ex. of sand and heavy silts.
17. 4. Floatable Floatables discharged to receiving waters create a
Solids variety of problems. Visible, floating material
degrades the aesthetics of waterways and their
shorelines, which in turn can contribute to loss of
use (e.g. beach closings) and can have an adverse
economic impact on recreation and business in
the area.
5. Colloidal also known as nonsettleable solids, do not dissolve in
Solids water although they are electrically charged, the particles
are so small that they will not settle out of the water even
after several years and they cannot be removed by
filtration alone, can be seen only with a high-powered
microscope. Ex. bacteria, fine clays, and silts. Colloidal
solids often cause colored water, such as the "tea color"
of swamp water.
18. 6. Organic Volatile suspended solids reflects the weight
Solids of organic matter in the dried solids that
burns off after combustion at 550 degrees C
and indicates the organic solids content of
the water sample.
7. Inorganic Non-volatile suspended solids reflects the
solids weight of solids remaining on the filter after
combustion and indicates the inorganic
solids (primarily sediment) content of the
water sample.
19. CHEMICAL CHARACTERISTICS
pH The term pH is used to describe the acid or base
properties of water solutions.
A pH value less than 7 in the wastewater plant influent
may indicate septic conditions of wastewater.
The pH values less than 5 and more than 10 usually
indicate that industrial wastes exist and are not
compatible with biological wastewater operations.
Pretreatment of these wastes at the source is usually
required since extreme pH values may damage
biological treatment units.
21. Dissolved oxygen
Dissolved oxygen (DO) in wastewater has a great effect on the
characteristics of the water.
Wastewater that has DO is called
aerobic or fresh. Aerobic raw
sewage is usually gray in color and
has a musty odor.
Aerobic sludge foam
Wastewater that has no
DO is called anaerobic or
septic. Anaerobic raw
sewage is usually black
and has an offensive
hydrogen sulfide or rotten Anaerobic
digester
egg odor.
22. Oxygen demand is the amount of oxygen used by bacteria and
other wastewater organisms as they feed upon the organic
solids in the wastewater.
Chemical tests such as the BOD (biochemical oxygen demand),
the COD (chemical oxygen demand), the ODI (instantaneous
oxygen demand or oxygen demand index), and the TOC (total
organic carbon) measure the "strength" of sewage. It is
important that organic wastes be removed to protect the
receiving body of water into which the wastewater plant is
discharging.
Sludge deposits, odors, and fish kills may occur
if removal is not adequate.
23. Nutrients
Nutrients are life-supporting nitrogen and phosphorus.
They stimulate excessive growths of algae and other aquatic
plant life. They are always present in domestic wastewaters
and are not removed during conventional primary and
secondary treatment.
Removal is accomplished by processes in addition to normal
wastewater treatment or tertiary treatment, when specific
reuse requirements require it.
24. BIOLOGICAL CHARACTERISTICS
Bacteria pathogenic (disease-causing) organisms such as
typhoid, dysentery, and other intestinal
disorders may be present in wastewater.
Tests for total coliform and fecal coliform nonpathogenic
bacteria are used to indicate the presence of pathogenic
bacteria. Because it is easier to test for coliforms, fecal
coliform testing has been accepted as the best indicator of
fecal contamination.
Fecal coliform counts of 100 million per 100 milliliters may be
found in raw domestic sewage. Detectable health effects have
been found at levels of 2,300 to 2,400 total coliforms per 100
milliliters in recreational waters.
25. Disinfection, usually chlorination, is generally used to reduce
these pathogens. Breakdown or malfunctions of chlorination
equipment will probably result in excessive discharge of
pathogenic organisms and can seriously affect public health.
Bacteria can also be classified according to their dissolved
oxygen requirement. Aerobic bacteria are bacteria that
require dissolved oxygen to live. Anaerobic bacteria cannot
live if dissolved oxygen is present. Facultative bacteria can
live with or without dissolved oxygen.
26. Viruses Wastewater often contains viruses that may produce
diseases. Outbreaks of infectious hepatitis have
been traced through water systems because of
wastewater entering the supply. sedimentation,
filtration, and disinfection, if used efficiently, usually
provide acceptable virus removal.
Parasites There are also many species of parasites carried by
wastewater. The life cycle of each is peculiar to the
given parasite. Some are dangerous to man and
livestock, particularly during certain stages of the
life cycle. Amoebic dysentery is a common disease
caused by amoebic parasites. Chlorination,
chemical precipitation, sedimentation, or sand
filtration is used to ensure protection against
parasites.
