Hello Dear, I'm an Engineer Aamir Khasru Mohammad Chowdhury. Nick name Aryan Khasru. I'm a Civil Engineer (B.Sc In Civil Engineering). But I am also working or interested as like as ​Architecture, Interior Design, Exterior Design, Event Management and made Model Making Idea, Handicraft & Handmade Design Idea for Home Decorate & Life Style etc. I come from Chittagong, Bangladesh. That's all about myself.

3. Industrial Waste Water -
 Wastewater is water whose physical, chemical or biological
properties have been changed as a result of the introduction of
certain substances which render it unsafe for some purposes such
as drinking.
 Wastewater treatment is the process and technology that is used to
remove most of the contaminants that are found in wastewater to
ensure a sound environment and good public health.

5. Industrial Wastewater Disposal/Management
Options In Order Of Preference:
 Reduce wastewater quantity
 Recycle the wastewater for flushing (where practical)
 Reuse the wastewater (generally after treatment) for
a beneficial purpose (either onsite or on a
neighbouring property) such as growing crops,
gardens or turf.
 Treat and discharge to sewer (if available)
 Treat and discharge wastewater to soakage or lined
evaporation pit (where practical)
 Treat and discharge to drains or watercourses,
meeting values.

7. Sources Of Industrial Waste Water-
 Agricultural Waste
 Iron and Steel Industry
 Mines and Quarries
 Food Industry
 Complex Organic Chemicals Industry
 Nuclear Industry

9. Types Of Waste Water -
Wastewater can be described as in the figure below :

10. Definition Of Concepts And Terminology -
 Stormwater Runoff is water from streets, open yard etc after a
rainfall event which run through drains or sewers.
 Industrial wastewater is liquid waste from industrial
establishments such as factories, production units etc.
 Domestic wastewater also known as municipal wastewater is
basically wastewater from residences (homes), business buildings
(e.g. hotels) and institutions (e.g. university). It can be categorize
into grey water and black water.
 Grey water also known as sullage is liquid waste from washrooms,
laundries, kitchens which does not contain human or animal excreta.
 Black water is wastewater generated in toilets. Black water may
also contain some flush water besides urine and faeces (excreta).
 Urine and faces together is sometimes referred to as night soil.

11. Different Types Of Industrial Waste
Physical :
 Electrical Conductivity (EC) indicates the salt
content
 Total Dissolved Solids (TDS) comprise
inorganic salts and small amounts of organic
matter dissolved in water
 Suspended solids (SS) comprises solid particles
suspended (but not dissolved)in water

12. Different Types Of Industrial Waste
Chemical :
 Dissolved Oxygen (DO) indicates the amount of oxygen in water
 Biochemical oxygen demand (BOD) indicates the amount of
oxygen required by aerobic microorganisms to decompose the
organic matter in a sample of water in a defined time period.
 Chemical oxygen demand (COD) indicates the oxygen equivalent
of the organic matter content of a sample that is susceptible to
oxidation by a strong chemical oxidant
 Total Organic Compound (TOC)
 NH4-N and NO3-N show dissolved nitrogen (Ammonium and
Nitrate, respectively).
 Total Kjeldhal Nitrogen is a measurement of organically-bound
ammonia nitrogen.

13. Different Types Of Industrial Waste
Biological :
 Total coliforms (TC) is encompassing faecal coliforms
as well as common soil microorganisms, and is a broad
indicator of possible water contamination.
 Faecal coliforms (FC) is an indicator of water
contamination with faecal matter. The common lead
indicator is the bacteria
 Escherichia coli or E. coli.
 Helminth analysis looks for worm eggs in the water.

14. Process Of Wastewater Treatment
 Physical unit operations
 Screening
 Comminution
 Flow equalization
 Sedimentation
 Flotation
 Granular-medium filtration
 Chemical unit operations
 Chemical precipitation
 Adsorption
 Disinfection
 Dechlorination

15. Objectives Of Wastewater Treatment-
 Reduction of biodegradable organic substances in
the environment: organic substances such as
carbon, nitrogen, phosphorus, sulphurus in organic
matter needs to be broken down by oxidation into
gases which is either released or remains in
solution.
 Reduction of nutrient concentration in the
environment: Elimination of pathogens
 Recycling and Reuse of water

16. Waste Water Treatment Processes -
Preliminary treatment
Primary treatment
Secondary treatment
Tertiary treatment
Disposal
