World Waste Map is honest and real - let's show together where the garbage is!
It all begins with little steps - let's do more than just notice the waste. Let's put it on a map and create together a powerful tool to communicate the illegal dumping issue. Later, the collected data can be used to prepare the logistics for the local cleanups.
World Waste Map is a free tool we have created for you and your friends, your neighbors. It's for everyone to map illegal waste locally and globally. You can simply download the application to your mobile

slaughter house discharge calculation
Calculation for discharge for a slaughter house:
Standards :
Waste water will be 1000
liter/buffalo and 100 liter/ goat., 3 liter / chicken(European Standard).
=================================
Calculation :
A. For Goat
/ Sheep :
Discharge
is 3 cu mtr per ton of goat / sheep
One goat
weighs 25 Kg
100 goat
weighs = 100 x 25 = 2500 kg= 2.5 ton
Discharge
in 100 goats = 3 x 2.5 = 7.5 Cu mtr = 7500 liter
============================
B. FOR
CHICKEN
Discharge is 1.7 Cu Mtr per ton of chicken
One chicken weighs 1.5 kg
500 chicken weighs = 500 x 1.5 = 750 kg =0.75 ton
Discharge in 500 chicken=0.75x1.7=1.275cu
mtr=1275 liter
TOTAL DISCHARGE = 7500 + 1275 = 8775 liter per day
LET US DESIGN FOR A TOTAL DISCHARGE 10,000 liter per day
DATA:
Water usage at plants such as this tend to be affected by the attitudes of both the in-house operators and the local veterinary inspectors to water usage and conervation. My experience of typical "normal" unit loads, (european experience), that can be achieved at a well run slaugher facility are set out below:
Cattle: 0.9 m3 /head and 3.5 kg BOD /head. (This includes an allowance for washing of livestock pens, and delivery vehicles, running / recovery of casings and edible fat, normal slaughtering aspects, very good blood collection, but excludes any allowances for cooking of cuts, pressing of paunch or belly grass materials, or for other value added processing).
Pigs: 0.5 m3/head, and 0.6 kg BOD per head. (This also includes an allowance for washing of livestock pens, and delivery vehicles, running / recovery of casings, normal slaughtering aspects, very good blood collection, but excludes any allowances for cooking, curing, or other valued processing).
Sheep: 0.08m3/head and 0.35 kg BOD per head processed.
(This too includes an allowance for washing of livestock pens, and delivery vehicles, running / recovery of casings, normal slaughtering aspects, very good blood collection, but excludes any allowances for cooking or other value added processing).

DAIRY ETP ONE MLD CAPACITY UASB BHOLA BABA DAIRY ALIGARH
DAIRY EFFLUENT TREATMENT PLANT (ETP) ONE MLD CAPACITY.BHOLA BABA DAIRY ALIGARH, 2007
TREATMENT FLOW CHART: DAF, UASB FOLLOWED BY ASP & FILTERS
These are the 4 top applications of the UASB reactors:
TREATMENT FLOW CHART: DAF, UASB FOLLOWED BY ASP & FILTERS
Ms Bhole Baba Milk food Industries Ltd. is situated at
khair road, Aligarh
The Dairy handle
about 10-lac litre of milk every day. Depending on the season, major
differences occur in the quantities of milk received from cooperative milk
federation and in the use of butter, butter oil and milk powder. The value
added products manufactured will be Casein,Milk Protien
Concentrate,Lactose-Both Food &Pherma,Demineralised Whey Protien,Whole Milk
Powder,Skimmed Milk Powder, & White Butter In Bricks Form, with future
planning to produce processed Cheese/Mozerella.
Generation
of Waste Water:
Waste water is generated mainly from Receiving Station,
Bottling plant, Cheese Plant, Butter Plant, Casein Plant, Condensed Milk Plant,
Dried Milk Plant, Ice Cream Plant, Water Softening units, Cooling towers,
Bottle and can washing sections and Various CIP systems,
Normally it is Cleaning of floors, equipment, etc., and
domestic waste from the dairy and staff quarters.
The unit will release an amount of estimated 10-lac litre
of effluent every
BASIS
& DESIGN DATA:
The designing of the plant
is based on the basis of parameters of generated effluent from similar type of
plant, which engaged in processing of milk and manufacturing Pure Ghee &
Milk powder.

What is Upflow
Anaerobic Sludge Blanket?
Upflow anaerobic
sludge blanket, or UASB, is a form of anaerobic (oxygen-free) digester used in
wastewater treatment. It is a methane-producing digester which uses an anaerobic
process and forming a blanket of granular sludge and is
processed by anaerobic microorganism.
UASB was developed in
1970s by Letinga in the Netherlands. It is essentially a suspended growth system in which proper hydraulic retention time (HRT) and organic
loading rate (OLR) is maintained in order to facilitate the dense
biomass aggregation known as granulation.
In the UASB process, the whole waste is passed through the
anaerobic reactor in an upflow mode, with a hydraulic retention time (HRT) of
only about 8-10 hours at average flow. No prior sedimentation is required. The
anaerobic unit does not need to be filled with stones or any other media; the
upflowing sewage itself forms millions of small "granules" or
particles of sludge which are held in suspension and provide a large surface
area on which organic matter can attach and undergo biodegradation. A high solid
retention time (SRT) of 30-50 or more days occurs within the unit. No mixers or
aerators are required. The gas produced can be collected and used if desired.
Anaerobic systems function satisfactorily when temperatures inside the reactor
are above 18-20°C. Excess sludge is removed from time to time through a
separate pipe and sent to a simple sand bed for drying.
The design of UASB pond is a function of:
The design of UASB pond is a function of:
§ COD input of
wastewater
§ Flow of wastewater
§ Organic loading
rate
§ Hydraulic retention
time
These are the 4 top applications of the UASB reactors:
o
Breweries
and beverage industry
o
Distilleries
and fermentation industry
o
Food
Industry,Dairy, Slaughter Houses.
o
Pulp
and paper
Together, these four industrial sectors account
for 87% of the applications. However, the applications of the technology are
rapidly expanding, including:
1. treatment of
chemical and petrochemical industry effluents
2. textile
industry wastewater
3. landfill
leachates
4. Conversions in
the sulfur cycle and removal of metals.
BHOLA BABA DAIRY GAS PRODUCTION & POWER GENERATION:
STREAM
–I :
Process Flow= 900 KLD having COD 3300ppm
Influent COD@ 3300 ppm = 2970 Kg
COD removed in a day (60% reduction) = 1782 kg
Bio
gas produced @ 0.1 cu mtr per kg of COD removed = 178.2 cu mtr per day.
Capacity
of gas holder:
Provide a gas holder of 200 cu mtr capacity.
POWER
GENERATION:
The bio gas produced in UASB process should be utilized
for production of electric power. The amount of electric power generated shall
be as under:
Bio Gas production = 178.2 cu mtr /day
Methane content (65.75%) = 117.16 cu mtr
Calorific value =28.9 MJ/N.cu mtr
Energy content 117.16x28.9x273/(273+30)=3050.85 MJ/Day
Generator efficiency--- 30%
Electricity generated =0.3x3050.85x1000000/3600x1000
=
254.23
Electric power generated = 254.23x0.04167=10.59 kw say 10 kw
= 1.25x 10=
12.5 kva.
STREAM
–II :
Mother Liquor= 100 KLD having COD 3,28,000 ppm will be
fed to the UASB reactor separately from the 900 kLD flow.
Influent COD@ 3,28,000 ppm = 32800 Kg
COD removed in a day (60% reduction) = 19680 kg
Bio
gas produced @ 0.1 cu mtr per kg of COD removed = 1968 cu mtr per day.
Capacity
of gas holder:
Provide a gas holder of 2000 cu mtr capacity.
POWER
GENERATION:
The bio gas produced in UASB process should be utilized
for production of electric power. The amount of electric power generated shall
be as under:
Bio Gas production = 1968 cu mtr /day
Methane content (65.75%) = 1293.96 cu mtr
Calorific value =28.9 MJ/N.cu mtr
Energy content 1293.96x28.9x273/(273+30)=33692.92 MJ/Day
Generator efficiency--- 30%
Electricity generated =0.3x33692.92x1000000/3600x1000
=
2807.74
Electric power generated = 2807.74x0.04167=116.99 kw say110 kw
= 1.25x 110=
137.5 kva.
TOTAL KW= 10+110 = 120 KW
We can go for a gas engine of capacity 65 KW If any gas is left , it will be flared or supplied
to staff quarters. Before the gas can be supplied, it has to be scrubbed in a
scrubber.
Capacity
of gas holder:
Provide a gas holder of 2200 cu mtr capacity.
