Talk on “Domestic Waste Water Treatment”
14.06.2017
A technical guest lecture meeting was held on 14th June 2017
at 6.00 pm in IE(I), Tamilnadu State Centre auditorium. The topic
of the day was on “Domestic Waste Water Treatment”. Er P R
Seshadri FIE, Past Chairman, IE(I), TNSC welcomed the
gathering and introduced the Chief Guest Dr. A. Abdul Rahman,
Professor, Department of Mechanical Engineering, Sri Sairam
Engineering College, Chennai. Dr. A. Abdul Rahman delivered
the lecture on the above topic with power point presentation.
At present, we face water shortage. In order to overcome the
problem waste water treatment technology has been developed
as water scarcity is mounting day by day. This project is aimed
to solve the problem by treating the waste water discharged from
our residence. Though there was a water problem, we somehow
managed to bring the water for our day to day life. It is the general
practice that after the water is used by the way of bathing, vessel's
cleaning, it is discharged to open space around the building or in
open drain. Initially the let out water in open space helps to grow
plants such as banana, but on long term this process makes the
soil sick.
Presently technology developed help us to treat the waste water
and make it suitable to various useful applications. Considering
a four member family as a single unit, it consumes about 550 liter

Theme: “Connecting People to Nature”
05.06.2017
WORLD ENVIRONMENT DAY
World Environment Day (WED) is celebrated every year on 5th
June to raise global awareness to take positive environmental
action to protect nature and the planet earth. It is run by the United
Nations Environment Programme (UNEP). The World
Environment Day has been started celebrating as an annual event
on 5th of June since 1973 at the Stockholm conference, Sweden
and then started celebrating annually at global level.
This year, the Tamilnadu State Centre of the Institution of
Engineers (India) observed the World Environment Day on
Monday the 5th June 2017 at the IEI Auditorium, Chennai. At
the outset, Er P R Seshadri, Past Chairman, IE(I),TNSC
welcomed the members present and briefed about the theme of
the day, “Connecting people to nature”. Dr S Virapan, Chief
Operating Officer, Chikara Techmep Pvt Ltd., Chennai was the
Chief Guest.
Dr. S. Virapan delivered his lecture and views on theme
“Connecting People to Nature”. In his presentation, he has given
more unknown information and facts of celebrating World
Environment Day. The same was concluded with fruitful
discussion and comments from specialists and Engineers from
different fields who attended the program.
Glimpse of presentation: Dr. S. Virapan started with introduction
of about World Environment Day, themes and hosted countries
of previous years. Explained about current year's theme
"Connecting People to Nature'. The theme pressurizes every
individual to get outdoors and into nature, to appreciate its beauty
and to think about how we are part of nature and how intimately
we depend on it. He discussed about the host country and how
it was connected with environment. Also he has highlighted some
practical experiences envisaged during site execution related to
environmental issues. The presentation portrayed how people of
different categories depends on environment, connected with
nature, impacts made on environment by humans. Further he has
also given solutions on what way one can protect our
Environment.
The most admiring part of his presentation that he has explained
about the Desludging process by using new technology called
“Geo-tube” with video clips where it is widely used in Malaysia
and Singapore water treatment companies for dewatering the
sludge from septic tanks and Sewage treatment plants.
Er P R Seshadri, Past Chairman, IE(I), TNSC presented the
memento to the Chief Guest Dr S Virapan. Er R Ramdoss,
Honorary Secretary, IE(I),TNSC proposed the vote of thanks.
About 30 members took part in this event.
IEI–TSC–News Bulletin, July 2017 3
per day after use, it disposes 200 liter of waste water and it is to
be reused prudently. In order to achieve this domestic waste water
treatment facility is developed and the efficiently functioning in
the developer's residence.
HOUSEHOLD WASTE WATER TREATMENT :
What is grey water: ‘Greywater’ is the term given to all used
water discharged from a house, except from toilet water (Black
water). Grey water includes shower bath, wash basin, kitchen sink,
dishwasher, washing machine and laundry tub water. This water
is called ‘grey’ water because it turns grey if stored for a while.
It also becomes quite smelly if stored for a day or so.
Grey water is sometimes called ‘sullage’. Toilet water is generally
called 'blackwater' or ‘sewage’. In most literature, both are
grouped together as ‘wastewater’. This convenient label is
misleading because grey water is very different from blackwater,
and neither should be wasted. Both can be re-used for garden
irrigation, but require different methods and levels of handling
because of their fundamental differences.
Grey water is far easier, safer and cheaper to re-use than black
water, Houses with composting toilets have no black water, and
should be encouraged. Greywater contains what is washed down
the drain, and so varies from house to house. For most houses it
is soap, shampoo, toothpaste, shaving cream, food scraps, cooking
oils, dishwashing detergents, laundry detergents, hair and lint.
Normal use of these products appears to do no harm to garden
soils and plants if greywater is used for garden irrigation.
Composition of waste water:
Source: Tooth paste, shampoo, moisturizer, shaving gel,
detergents, soaps, hair spray, after shave, lotion, cologne,
moisturizer, etc. Sodium bicarbonate, sodium monofluoro-
phosphate, calcium phosphate, saccharin, washing soda, glycerin,
peppermint extract (tooth paste). Cocamide DEA (shampoo,
moisturizer), propylene glycol (shaving gel), sodium lauryl
sulphate/fluoride (shampoo), benzaldehyde (shampoo, detergent,
shaving cream, bar soap), benzyl acetate (hairspray, after shave),
benzyl alcohol, camphor, ethanol, ethyl acetate, limonene, alpha
pinene, g-terpinene, terpineol (shaving cream, lotion, skin
moisturizer, cologne, detergents, etc.), acetone, methylene
chloride, ?-citronellol,? -myrcene, ?-phenyethyl alcohol, p-
dichlorobenzene are some of the chemicals in the composition of
waste water in addition to the kitchen organic wastes.
The Construction Detail: The tank is known as anaerobic baffed
reactor a closed container made up of FRP, a corrosion resistant
material. It contains baffle arrangement indicating stirred tank
reactors that aids Zig- Zag water flow in vertical plane. There
is also place in the system for boarding and lodging of anaerobic
bacteria by coating. The tank has sufficient free board to give
space for tapping gasses formed.
Hence, hydroponic system is selected and installed in which
floating macrophytes have been used to take nutrients present in
the waste water to reduce the organic load.
Technology: The waste water allowed for hydraulic retention
period overnight that helps the anaerobic bacteria to consume the
organic material present in the waste water. Some time fungi
species such as Aspergillus sp, Cladosporium sp and mucor sp
have given considerable success yet these are not considered in
the present system. A negligible amount of fuel gas is formed
during treatment get dissolves in the water. The treated water
satisfies the standard disposal norms. however, the partially treated
waste water by recovering 60 to 70% BOD is collected into a
plastic 30 litre capacity keeping submersible pump. The water is
circulated in the hydroponic system which contains plants. The
water floating plants as such as Eichhornia, Wolfia, Pistia,
Spirudela and Lamna were collected from the site of Cooum river
bank and elsewhere used in the hydroponic system. The partially
treated water is used for circulation instead reversible osmosis
(RO ) water. The submersible pump is used to recycle the water
into the hydroponic system. Thus, waste water after treatment is
reused and excess treated water is recharged into the ground.
Uniqueness:
So far we have various electrical and electronics gadgets. This
one presently installed is a new addition to household can provide
water which is in great demand. We have waste water treatment
plan for capacity in the range of 1 MLD, 5MLD, 20MLD.
However, such treatment unit require huge investment in terms
of crores, engagement of technical personal, periodic dosage of
chemicals, sumps and pumps and consumption of power. Whereas
this system is cost effective, easy to install in addition simple to
operation and maintenance. It recovers precious water from own
source of used water. Yes there is no more waste water it is really
a useful water. This technology really makes the city smarter .
The advantages are listed below:
• This is a cost effective technology.
• The treated water is nutritious. Hence suitable for plants.
• No production of sludge, Hence disposal of sludge is totally
avoided.
• Reduces load on public sewage treatment units.
• Efficient use of water and avoids carriage of waste water.
• Treated water can be useful for flushing, vehicle washing and
floor cleaning.
• Recharge of ground water is possible through out the year.
• Soil sickness is avoided thereby pleasant surroundings of
residential space is possible.
Er P R Seshadri, FIE, Past Chairman, IE(I), TNSC presented the
memento to the Chief Guest Dr A Abdul Rahman . Er R
Ramdoss, Honorary Secretary proposed the vote of thanks. About
40 members participated in the program.
