IF WASTE WATER FROM HOTEL, HOSPITAL EXCEEDS
THE ABOVE VALUE, ONE PETP IS TO BE INSTALLED FOR TREATING WASTE WATER AND BRING
IT WITHIN LIMITS MENTIONED ABOVE.
Our Consultancy & Supervision scope:
We offer our work on consultancy basis for the Hotels
,hospitals, restaurants, wedding hall, ccar service station, tea garden and
other industries. . All the civil & execution work will be done
by the respective Hotel , under our
guidance from initial survey to the final report submission to the Pollution
Control Board of Assam (PCBA).
1.Preparation
of drawing as per site condition for each
location of hotels , it’s size , their
complexity and need of the hotel
. Thus there is no common solution for all hotels if Customized concept
is adopted , So will provide customized system plant for each
site. Also, at various sites there are exiting septic tanks and other tanks
,pipes etc which can be adjusted in our proposed system which will reduce
construction cost.
2 . We shall Provide a Flow
Chart & project report for
submission to the PCBA
3.We will supervise the progress
of the civil works during construction time of the ETP.
4.We will provide you a
list of dealers from where you can buy
the pump , blower and chemicals.
5..We will train your staff
for first 3 days how to run the plant & provide a maintenance manual for
the plant
6. We will provide a first water test report to be submitted to pollution board
7. We shall help in filling of the Documents to be submitted to the
PCBA . All the legal fees & dues needs to be cleared by the client . The
extra cost for Consent to operate or NOC is not included in the Consultancy
DATA
REQUIRED:
a)Quantity of waste
water generated liter per day
b) Waste Water test report .
.
TREATMENT METHOD OF PETP:
Chemical pre treatment followed by filtration
Flow
Chart of PETP:
IN-Screen—Oil Trap---Collection
Tank---Primary Sedimentation--— ------Disinfection Tank—Pump---Filter ----Out
to drain
Details of different units of the proposed system
A)CHEMICAL
TREATMENT OF WASTE WATER IN PETP
a)
Screen :Waste water will flow through these drains
by gravity flow from the inlet manhole. To remove large floating objects , bar
screens and oil traps are provided inside the incoming drain itself .
b)
Collection tank: All waste water will be collected
here .Lime and Alum will be added here and mixed by air bubbling from a air blower..Waste
water will flow by gravity to the next unit.
c)
Primary Sedimentation tank(PST): The chemical
sludge will be settled here. Waste water will flow by gravity to the next unit.
Sludge is removed by sludge pump to sludge drying beds.
d)Disinfection tank : Disinfection is done here with bleaching powder to
remove colour, bactaria and other
contaminants and than pumped to the pressure
sand filter and finally released to drain.

STANDARDS FOR POTABLE WATER :
Suspended Solids < 500 ppm
Turbidity < 10 ppm
B-Coli—NIL
M.P.N. – one number in 100 ml
Hardness <100 o:p="" ppm="">100>
Chloride<250 o:p="" ppm="">250>
Iron and Manganese < 0.3 ppm
PH= 6.5 to 8
Lead< 0.1 ppm
Arsenic< 0.05 ppm
Sulphate < 250 ppm
Carbonate Alkalinity < 120 ppm
Dissolved Oxygen = 5 to 6 ppm
B.O.D—NIL
Any parameter above the
limits as mentioned above will require treatment
Treatment method: Chemical oxidation followed by filtration
Iron or
manganese also can be oxidized from the dissolved to solid form by passing
through oxidizing agent called MNO2.
The resulting solid particles then must be filtered. When large concentrations of iron are present, a flushing sand filter may be needed for the filtering process.
Any filtration material requires frequent and regular backwashing or replacement to eliminate the solid iron/manganese particles. Some units have an automatic backwash cycle to handle this task.

FIRST FILTER: MNO2 FILTER
FIRST FILTER: MNO2 FILTER
Filter Media – MNO2 Manganese di oxide
Iron and Manganese removal
Supplied in 25Kg bags
What it is and how it works
MNO2 is a oxidizing agent to precipitate iron and/or
manganese. Because the presence of iron is most common, iron removal is
the usual application for MNO2. Under suitable conditions, the iron and
dissolved oxygen in water react on contact with the MNO2 filter bed and,
as a result, the iron is precipitated in the form of hydroxide. This is a
flocculent material which is filtered out in the bed of anthracite.
Periodic backwashing flushes out the accumulated iron and the MNO2 is
again ready to perform its function. MNO2 is not consumed in the iron
removal operation.
SECOND FILTER:
SAND-ANTHRACITE FILTER FOR IRON REMOVAL
A sand-anthracite filter or
dual media filter/multi-media filter is primarily used for the removal of
turbidity and suspended solids as low as 10-20 microns. Inside a
sand-anthracite filter is a layered bed of filter media. The bed is graded from
bottom to top as follows:
1st layer
|
=
|
gravel support bed
|
2nd layer
|
=
|
2mm filter sand
|
3rd layer
|
=
|
fine filter sand
|
4th layer
|
=
|
anthracite
|
How it works:
Anthracite
has a high affinity for iron, especially when it is coated with potassium
permanganate, and is therefore often employed for iron and manganese removal.

Groundwater contamination cases rising in State
Ajit Patowary
GUWAHATI, Jan 28 - Cases of contamination of groundwater in the State are swelling up everyday, making groundwater unsafe for consumption. According to the official data, the number of the State’s districts which have got their groundwater contaminated by fluoride and arsenic has shot up to 22 and 21 respectively from 19 and 20 respectively in 2014-’15.
GUWAHATI, Jan 28 - Cases of contamination of groundwater in the State are swelling up everyday, making groundwater unsafe for consumption. According to the official data, the number of the State’s districts which have got their groundwater contaminated by fluoride and arsenic has shot up to 22 and 21 respectively from 19 and 20 respectively in 2014-’15.
According to the data available with this newspaper, in 2014-’15, the
arsenic affected districts of the State included Baksa, Barpeta, Bongaigaon,
Cachar, Darrang, Dhemaji, Dhubri, Goalpara, Hailakandi, Jorhat, Kamrup,
Karimganj, Kokrajhar, Lakhimpur, Morigaon, Nagaon, Nalbari, Sivasagar and
Sonitpur.
This year, Tinsukia has also been found to be affected by arsenic,
raising the number of affected districts to 21, said the sources.
Till 2013-’14, nine districts – Barpeta, Dhubri, Goalpara, Golaghat,
Jorhat, Kamrup, Karbi Anglong, Karimganj and Nagaon – were found to be affected
by fluoride.
But in 2014-’15, with the inclusion of Baksa, Cachar, Chirang, Darrang,
Dibrugarh, Morigaon, Nalbari, Sivasagar, Sonitpur and Udalguri, the number of
affected districts rose to 19.
In 2015-’16, with the inclusion of Bongaigaon, Lakhimpur and Tinsukia,
the number of fluoride-affected districts have shot up to 22, sources said.
According to experts here, the trend of rise in the number of fluoride
and arsenic affected districts should be studied, together with the impact of
such contamination of groundwater, which is used by the people of many areas in
these districts for the purpose of drinking as well as domestic use, on human
and animal health.
Except in the two districts of Karbi Anglong and Nagaon, no
comprehensive health impact studies of groundwater contamination in the rest of
the districts has so far been known to have been conducted, said the experts.
The origin of fluoride so far is known to be geogenic.
The State’s Department of Mining and Mineral may undertake such studies,
involving also the Public Health Engineering Department (PHED), Council of
Scientific and Industrial Research (CSIR), Central Ground Water Board (CGWB)
and the North Eastern Regional Institute of Water and Land Management
(NERIWALM) in this regard, said the experts
