Biogas Engines Power Cow
Manure-to-Energy Plant
 NEW
DELHI, India -- A GE Energy Jenbacher biogas engine is
powering a successful demonstration cattle manure-methane
cogeneration plant at a large dairy complex in India’s
northwestern state of Punjab, helping to address the
region’s mounting energy and environmental needs.
The Jenbacher biogas plant was
cited as one of a number of successful GE projects during
the formal launch of GE’s ecomagination program in India on
February 20 in New Delhi. Ecomagination is GE’s commitment
to address challenges such as the need for cleaner, more
efficient sources of energy, reduced emissions and abundant
sources of clean water.
Since late 2004, GE’s 1-MW
Jenbacher biogas cogeneration system has supported the model
waste-to-energy conversion plant at the Haebowal dairy
complex in the city of Ludhiana. The 50-acre Haebowal
complex, one of two centralized cattle facilities in
Ludhiana serves 1,490 dairy operations that own 150,000 head
of cattle, generating a total 2,500 tons of manure daily.
GE’s Jenbacher demonstration project uses the biogas with
high methane content created during the anaerobic digestion
of 235 tons of cow manure per day to generate electricity
and thermal power (hot water).
In order to reduce the facility’s
greenhouse gas emissions (methane has 21 times the
greenhouse warming potential as carbon dioxide) and to
prevent the improper disposal of the animal wastes, the
Punjab Energy Development Agency (PEDA) installed and
commissioned this demonstration power generation facility
based on the biomethanation process of cow manure. PEDA is
the State Government nodal agency for renewable energy
projects in Punjab under the financial and technical support
of the Ministry of New and Renewable Sources, Government of
India.
Surplus energy after meeting the
plant auxiliary requirements from the engine is sold to the
local grid of Punjab State Electricity Board (PSEB), while
water heated by the engine is used to assist the
fermentation process in the digester. In addition to the
energy and thermal output of the plant, remnants from the
digester process are used as fertilizer by local farmers.
“We are very pleased with the
results of this biomethanation facility to mitigate the
environmental impacts from such a large concentration of
cattle in one area,” said Shri M.P. Singh, Senior Project
Manager of PEDA. “Expanding the recycling of cow manure for
energy and fertilizer, while simultaneously improving our
air and water quality, is clearly within our mission to
promote a sustainable energy future. We are increasingly
looking for possibilities of establishing more such plants
in the state of Punjab.”
“A critical priority for rural
regions throughout the world is to replace inefficient waste
disposal and fuel-burning practices, which can have negative
impacts on the environment, with newer, more efficient
energy technologies including GE’s Jenbacher biogas
systems,” said Prady Iyyanki, CEO of GE Energy’s Jenbacher
gas engine business. “We expect the Haebowal demonstration
project to spur other dairy customers to install similar
systems that will greatly mitigate the environmental impacts
of their operations.”
GE Energy’s Jenbacher gas engine
business is a leading manufacturer of gas-fueled
reciprocating engines, packaged generator sets and
cogeneration systems for power generation. GE’s Jenbacher
gas engines run on natural gas or a variety of specialty
waste gases, including biogas, landfill and coal mine
methane and industrial waste gases.

New Ammonia Analyzer for
Wastewater
 Loveland,
CO -- Hach Company announces the new AMTAX™ sc Ammonia
Analyzer with detection limits as low as 0.05 mg/L and as
high as 1000 mg/L Ammonia. This versatile analyzer can be
used anywhere in the wastewater treatment process—from the
influent or start of the nitrification process where ammonia
levels are at their highest to the effluent where ammonia
levels are at their lowest.
Nutrient removal is a critical and sensitive process in
wastewater treatment. Quick response is vital for optimal
operation and the AMTAX sc offers a fast response time of
only 5 minutes, including sample preparation, and the
ability to choose the measurement interval.
Use it
where you need it! The AMTAX sc is designed to be installed
at the measurement point—including outdoor installations.
The housing is weatherproof and lockable so that the AMTAX
sc can be installed right at the basin, even in the toughest
climates. The unit comes complete and assembled—no separate
housing is required.
The
Hach AMTAX sc determines ammonia concentration using a gas
sensitive electrode (GSE) that uses liquid- to gas-phase
conversion to expel and measure ammonia concentration.
Reagents are consumed over a 3-month period.
A
low-maintenance filtration probe is available for use with
the AMTAX sc that removes particles larger than 0.15 µm.
Filtrate is sent to the analyzer while air bubbles
constantly clean the filtration membrane. When cleaning is
required, a simple wipe with a cloth or sponge is all that’s
needed. The analyzer may also be used with existing
filtration systems that deliver a continuous sample stream.
For
more information, contact:

Hydranautics Awarded 39 MGD Ulu Pandan Plant
 Oceanside,
CA -- Hydranautics, the global leader in membrane technology,
was selected to provide 9,100 ESPA2+ elements for the 39 MGD
(148,000 m3/d) secondary effluent wastewater plant on the island
country of Singapore. Ulu Pandan is the fourth and largest
NEWater project by the PUB (Public Utilities Board) that is
designed to purify and reuse wastewater for industrial water
applications.
Hydranautics’ elements have
previously been selected for three of the four existing NEWater
plants including the Bedok and Kranji Water Reclamation Plants.
These two facilities represent 19 MGD (72,000 m3/d) of water
recycling capacity and have proven the reliability and
performance of Hydranautics’ membrane technology for this
difficult application.
The PUB’s NEWater initiatives were
established to help the country become more self-sufficient. Ulu
Pandan was awarded to Keppel Seghers Engineering Singapore Pte
Ltd., who was awarded a 20-year design-build-own-operate
contract for the water recycling plant. Keppel Seghers in turn
selected Hydranautics’ ESPA2+ membrane elements for the reverse
osmosis membrane treatment process. ESPA2+ was selected for its
high productivity and high rejection as well as its proven track
record treating municipal wastewaters.
Hydranautics’ ESPA (Energy Savings
Polyamide) membranes operate at significantly lower pressures
than competiting RO elements, providing considerable energy and
operating cost savings. The ultra-high, active area membrane
ESPA2+ elements produce 12,000 GPD (gallons of water per element
per day) (45.4 m3/d) at 99.6% nominal salt rejection (99.5%
minimum). The high area ESPA2+ element offers the best
combination of low pressure and high rejection of any brackish
water element available on the market today.
Hydranautics and parent company Nitto
Denko together form the industry leader for membrane development
with a focus on unique surface coatings. The resulting membrane
technology provides solutions for customer’s most demanding
water treatment needs.

Hydranautics’ ESPA membranes please call 1-800-CPA-PURE, visit

Mr. Blanchard wants help with dissolved oxygen:
I have a DI system I use for
my dilution water. I am having problems with high
initial DO's.
I have this problem
occasionally. I change my filters and usually the DO's
go down. I also disinfect tank monthly. This
time the DO's will not go down.
Anyone have a possible
solution? (Click

Thanks,

Mr. Faiz needs help with return activated sludge rate:
Literature proposes various
ways to estimate the RAS rate. One way is to equate the RAS
to the fraction of settled solids of the activated sludge
reactor. For instance if there are 250ml/liter of Sol. Sed.
in a 1 liter cylinder after 30 minutes, the RAS rate should
be set to a third (250/750) of the influent.
Another way is to use the
formula:
Qr/Q = MLSS/(Sludge RAS concentration - MLSS)
The first one has the merit
to be rapid to compute. So I would like to know if either of
the 2 formula is applicable for the case of a complete mix
activated sludge?
