life time achievement ERDF Excellence award 2015 Dr Syed Iftikar Ahmed, AIDS PREVENTION SOCIETY, GUWAHATI, ASSAM, INDIA

Proud Moment. Our Dear Munu Ka Syed Ahmed getting life time achievement ERDF Excellence award 2015 for his work on AIDS in NE States.His NGO AIDS PREVENTION SOCIETY,GUWAHATI.

A Message From Dr.Syed Iftikhar Ahmed

My dear friends,                                

I  really feel  honoured to have recieved the ERDF Excellence Award 2015 from the Honb'le. Chief Minister of Assam and his kind words of praise  recognizing   our  work .                                        

 It  has been a  long journey.                             

 I feel overwhelmed with your warmth and wishes which makes me feel that the last 30 years of my struggle was worth fighting though when I look back I miss all those colleagues, friends and hundreds of young lives that we have lost on the way particularly in Manipur, Nagaland and Mizoram. . It was a frustrating fight. But I did not lose focus. My Heroin  drug user population with HIV and Hep  B and  Hep C co infection  were dying fast even before we could initiate ARV . When I was invited by the President of the UN to the UN General Assembly in New York  in 2008 and again in 2010 ,  I raised the issue of this co inf in North East India.  Advocacy paid off . Today we have range of free ARTs in  India and Hep treatment with Heroin substitution with Buuprenorphine in north east India unthinkable  ïn  the past.  My clients are living healthy and productive  for more than 20 years . HIV is now  a chronic manageable disease . I had to explain this in the Legal Colloq. for two days through my presentations   convened by Justice Ranjan Gogoi which was inaugurated by the Chief Justice of India and in presence of  a large number of legal luminaries of the country . 

Currently our organisation is involved  in AIDS Vaccine development programme  in collaboration with International AIDS Vaccine Initiative - IAVI.                       

 Thanks again to all of you.

I started my NGO work in Guwahati after my return from UK with the establishment of AIHC ( Assam Imdadiya Hospital Committee) in 1983 and the AAIS Clinic in Ambari in 1984. Late Shri Hiteswar Saikia , the then Chief Minister of Assam helped us and encouraged us in establishing the AAIS Clinic and seen in the pic examining him in the Clinic on the opening day . Today on his Death Anniversary we pay our homage to him . As founder Chairman of the Clinic along with our team of medical doctors comprising Dr Medhi and Dr M I Khan could provide free medical services to a large number of people since then including Lab Tests, Immunisation , regular health camps and Eye Check up Camps with Cataract surgeries throughout the state of Assam .

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.
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.

DESIGN EXAMPLE OF BIO GAS PLANT
http://archive.unu.edu/unupress/unupbooks/80362e/80362E0j.htm
FIG. 3. Chinese Biogas Plant Design
The digester is of standard KIVC design, consisting of a cylindrical underground chamber using 23-cm (9 in.) brick walls and a concrete floor. It has two standard 10-cm (4 in.) cement household pipes for the inlet and outlet. A feed trough, slurry pit, and soaking pit for the digested slurry are provided. Figure 1 shows the details. The only departure from the standard design is provision of a water trough to hold the gas holder (as explained below).
The gas holder consists of a geodesic dome made of wood, to which a vinyl balloon is secured. The balloon is made of heat-sealed vinyl fabric available on the market. The whole assembly sits inside a water trough that serves two purposes: it prevents gas leakage through the water seal if filled with 20 to 30 cm of water, and it helps to anchor the balloon. Hooks around the gas dome also help to secure the structure so that it does not blow off under pressure. The dome struts and hubs were made as shown in figure 2A and B.

Design of Biogas Plant
Number of cows	4
Assuming 1 cow produces	10 kg of dung/day
Amount of dung produced by 4 cows	40 kg
Amount of gas produced by 1 kg of dung	0.05 m�
Amount of gas produced by 40 kg of dung	2 m�
Daily requirement of gas for cooking and lighting
for 1 person	0.5 to 0.6 m�
2 m� of gas per day will provide cooking and lighting for	2/ 0.6 to 2/0.5= 3 or 4 persons

The volume of the fermentation well should be at least 30 times as large as the daily input. Since manure is usually retained in the fermentation well for about six weeks, it is desirable for the well to be about 45 times the volume of the daily input.

Using a 1:1 ratio of cow dung and water:
Daily input of cow dung	40 kg
Daily input of water	40 kg
Total input	80 kg
Volume of the well required
(45 times the daily input)	80 x 45 = 3,600 kg
100 kg of dung and water occupy	1 m�
3,600 kg of dung and water occupy	3.6 m�
Digester tank capacity required	3.6 m�

The gas holder volume should be enough for 60 to 70 per cent of one day's production.

70 % of 2 m� gas	[70 x 2] /100 = 1.4 m�
Digester tank capacity	3.6 m�
Gas holder capacity required	1.4 m�

Size of the Digestion Tank
Assume 1.75 m as the internal diameter of the digestion tank.

The depth required will be	1.5 m
Using a 20 cm thick wall, the external diameter will be	1.75+0.2+0.2m = 2.15 m

Size of the Gas Holder
A hemispherical PVC balloon is used as the gas collecter.

Assuming diameter of the dome to be	1.9 m
Volume of the dome (half sphere)	1.795 m�

Design of Dome to Support the Gas Holder
Type	2 frequency dome,Class I,
	Method I
Diameter of dome	1.95 m
Radius of dome	0.975 m = 38.38 in.
Length of struts (including hubs)
Long struts	radius of dome x 0.618= 23.75 in.
Short struts	radius of dome x 0.5465= 21 in.
Distance from centre of hub to centre of hole at end of strut	2.75 in.
Length from centres of holes at each end of strut to ends of strut	1.5 in.
Actual length of long struts	23.75 in. - (2 x 2.75 in.)
	+ (2 x 1.5 in.) = 21.25 in.
Hole-to-hole distance	18.25 in.
Actual length of short struts	21 in. - (2 x 2.75 in.)+ (2 x 1.5 in.) = 18.5 in.
Hole-to-hole distance	15.5 in.
Number of long struts required	35
Number of short struts required	30
Number of five-element hubs required	6
Number of six-element hubs required	20

How much Biogas can I produce?

The following is a calculator for estimating the amount of biogas your operation can produce. The calculator is a guideline only and should not be used for design purposes.

Choose the biogas production number that applies to your operation...
Example: 600 sow farrow to finish operation, choose Farrow to Finish 

Hogs

Cubic metres biogas per hog per year

Farrow to Finish

720

Farrow to Wean

222

Farrowing

174

Weaner

24

Feeder

78

Dairy

Cubic metres biogas per cow per year

Freestall

860

Multiply the number of animals by biogas production number...
Example: 600 hogs x 720 m³ biogas / hog / yr = 432000 m³ biogas / year

Multiply the result by the numbers below for cogeneration of electricity and heat...

____________ x 1.7 kWh/ m³ biogas = _________ kWh of electricity per year
____________ x 7.7 MJ/ m³ biogas = _________ MJ of heat per year

Multiply the result by the numbers below for heat production using boiler....
____________ x 15 MJ/ m³ biogas = _________ MJ of heat per year

Different methods of filtering and purifying drinking water

Water Purification and Treatment Technologies

A comprehensive look at the different methods of filtering and purifying drinking water.

The drinking water treatment technologies used in the majority of systems include one or more of the following methods or media types:

• Sediment Filters - Ranging from 1 to 20 microns are normally used as a prefilter to protect and extend the life of other filters.
• Activated Carbon, including Granulated Activated (GAC), Carbon Block, and Catalytic Carbon – Standalone, or combined with other technologies to remove chlorine, chloramines, VOCs, MTBE, and a wide range of contaminants including lead and mercury.
• Water Softeners – Used to soften "hard" water using ion exchange technology that exchanges magnesium and calcium with sodium or potassium.  Water softeners are not designed to purify water that is microbioligically unsafe.
• BASF ATS Media  – Home systems, usually combined with activated carbon.
• Steam Distillation – Systems for home, business and commercial use.
• Reverse Osmosis (RO) - Systems for home, business and commercial use.
• Deionization – Not recommended for drinking water.
• Ozonation – Nature’s natural sterilizer.
• KDF Media – Advanced zinc-copper alloy with the widest range of contaminant removal.  Usually combined with Granulated Activated Carbon.
• Ceramic – Alternative to germicidal UV-C for filtration of bacteria, etc. 
• Activated Alumina – Specifically designed to remove fluoride and arsenic by adsorption.
• Bone Char – The best material for removing fluoride. Bone Char also removes chlorine, heavy metals and radioactive isotopes. For this reason, it is placed after a chlorine adsorption filter in all OPUS systems, to ensure maximum efficiency for adsorbing fluoride.
• Ultraviolet Germicidal Irradiation (UV-C) - To disinfect microbioligically unsafe water.
• Ultra-Filtration (UF) - Ultra Filtration uses membrane technology to reject contaminants from 0.01 to 0.2 microns. UF is effective in the removal of bacteria, pyrogens, high molecular weight dissolved solids and other water contaminants without removing healthful minerals.
• Bioceramic Water Amplification (BCWA) –Technically not a filter, BCWA improves the health promoting qualities of water by increasing alkalinity, oxygen, active hydrogen ions and healthful minerals, while lowering the ORP (Oxidation Reduction Potential), giving water antioxidant properties. BCWA is available as an inline filter that can be added to an existing water treatment system, integrated into a drinking glass (Alkalark) to treat individual glasses of water, and as Balance Water Sticks designed to be inserted into your drinking bottle.
