Asia
: Siemens acquires Chemitreat Group
 Erlangen,
Germany -- Siemens announced today that it has acquired the
Singapore-based private limited Chemitreat Group to expand
the water treatment business in South East Asia. Chemitreat
will become part of Water Technologies, a business unit of
Siemens’ Industry Solutions division. With sales of more
than EUR25 million in 2007 and 240 employees, Chemitreat
provides water treatment technologies and services in
Singapore, Thailand, Malaysia, Philippines and China.
“Chemitreat has been a very
respected player in our region for more than 30 years”,
stated Jagannath Rao, responsible for the Siemens Water
Technology business in Asia. “Chemitreat covers services
from operations to maintenance for both industrial and
municipal customers and holds technology expertise in key
industrial applications including high purity water
treatment”.
The acquisition is primarily
about geographic expansion in South East Asia allowing
better market penetration.
“The market segment for water
treatment equipment and services is growing by 7-9 percent a
year in Asia”, Rao stated, “and Chemitreat helps us to
better address the growing water needs of industry and the
public in this region”. In addition, there are no
significant overlaps between the Chemitreat and Siemens
water treatment portfolio. So, “the acquisition helps us
supplement our existing portfolio and extend our regional
footprint”.
“The acquisition continues our
growth strategy in the Asia region”, said Chuck Gordon, CEO
of Siemens Water Technologies.
Since 2006 Siemens has ramped up
its water treatment business in the Asia-Pacific region with
joint ventures in China and a research and development
center in Singapore. With an investment of EUR25 million
over five years, Singapore will be developed as a business
and technology center for research, development and
engineering of water and wastewater treatment technologies.
“With Chemitreat we now bring our
water treatment and service portfolio to Malaysia, Thailand
and Philippines”, Gordon said, “This will provide us with a
strong platform to accelerate our market entry into other
countries, such as India and Vietnam”.

Manure : Texas Biogas Plant
Ramps Up
 Terrytown,
NY -- Environmental Power Corp. announced that its Huckabay
Ridge facility in Stephenville, Texas, reached full capacity
production levels of pipeline-quality biogas in late
January. The facility is expected to produce approximately
635,000 million British thermal units of biogas per year
from manure and other agricultural waste. Environmental
Power's wholly owned subsidiary Microgy Inc. has the
exclusive American license for the technology provided by
Danish Biogas Technology AS.
“This project is the largest of
its kind in North America,” said Mark Hall, senior vice
president of external affairs. “We’re located in a compost
yard in Stephenville because Erath County is the largest
milk-producing county in Texas. We take manure from about
10,000 cows, borrow it for about 20 days and return the
solids to the compost yard. The liquids are used for
fertilizer.”
The biogas, which is refined to
have the same characteristics as natural gas, is currently
being sold to the Lower Colorado River Authority, a utility
in Texas. In October, Environmental Power will sell the
biogas to Pacific Gas & Electric Co. in California as part
of a 10-year contract for 8,000 MMBtu per day.
To fulfill this contract,
Environmental Power is following an aggressive development
plan.
“We expect to have seven to 10
facilities under construction in 2008,” Hall said.
These facilities under
development have an anticipated annual production of 4.9
million MMBtu. The first facility broke ground in December.
The biogas plant will be located at the JBS Swift & Co. beef
processing facility in Grand Island, Neb., and is expected
to generate 235,000 MMBtu per year. Other projects are to be
sited in California, Texas, Colorado and Idaho.
Environmental Power refined its
technology at three much smaller facilities in Wisconsin,
which started production in 2005. Each site processes manure
from approximately 1,000 dairy cows, and the biogas is used
on-site in generators owned by a rural electric cooperative.

Water Fun : The "Hydrodynamic
Deluxe Building Set"
 Jacksonville
Beach, FL -- Editors Note: I found this online recently and
it reminded me of my old erector set, chemistry set and
other similar items I grew up with. I thought this would be
of particular interest for the "young" engineer in your
family. Its called the "Hydrodynamic Building Set" and
includes all the parts necessary for him/her to build their
own water treatment plant, chemical plant, etc. I wish I had
one when I was 10 years old!
Started by two chemical engineers, a husband and wife team,
Bridge Street Toys has reintroduced the "Hydrodynamic Deluxe
Building Set", "Bridge & Turnpike Set" and "Girder and Panel
Set", originally sold by Kenner Toys back in the 1960's and
1970's. The Hydrodynamic Deluxe Building Set is awarded a
Best Products of 2007 iParenting Media Award. Below is
a description from the company's web site:
---------------
Build a model of a manufacturing plant with working tanks,
pipes, valves and pump with this unique construction toy. A
color instruction book provides building instructions and
several examples of different structures you can build with
the set.
With
the Hydrodynamic Building Set you can build a model of an
ice cream factory, a water treatment plant, a distillation
plant and many other industrial structures. Discover how a
siphon works. Balance the flow through the plant by
adjusting the valves. The user learns the basic principles
of fluid dynamics while constructing and playing with this
toy.
This
set comes with a large tray and footing in which you build
the structure. The tray measures approximately 10 inches by
16 inches by 3 inches deep. The tray and the footing are
both white. The footing has a grid of 12 holes for columns
(4 x 3 configuration). Build the structure using the footing
in the tray for the base, place the submersible pump in the
tray, add water until you completely cover the inlet on the
pump, and then enjoy reconfiguring the pipes, opening and
closing valves and watching the action!
This
building set includes an electric pump, siphon tank, large
square tank, small and large round and cone bottom tanks,
float valve, tilt scale, ball flow meter, water wheel, spray
head, and assorted valves, pipe holders and pipe. The pieces
are interchangeable with all other Girder and Panel and
Bridge and Turnpike Building Sets and are HO scale. This set
is great for doing middle and high school level science fair
projects.
----------------
I hope
you enjoy seeing this, as much as I do. I certainly would
want my kids to have as much fun as I did with my good old
erector set. The "Hydrodynamic
Deluxe Building Set" is available on Amazon, click the
link to learn more.

Formula Combats Greenhouse
Gases from WWTP's
 Halle/S,
Germany -- The cost of treating wastewater contaminated
with nitrogen could be lowered in future. Soil
scientists at the Helmholtz Centre for Environmental
Research (UFZ) have developed a new mathematical model
which can help determine the optimum conditions for
microbiological water treatment.
Using the stable natural
nitrogen isotope 15N, this mathematical model, which is
the most accurate to date, can for the first time
calculate exactly the quantities of dinitrogen (N2)
produced by the complex biochemical treatment processes
anammox and denitrification and the background levels in
the atmosphere, according to the researchers writing in
the specialist journal, Rapid Communications in Mass
Spectrometry. This means that in future the
effectiveness of such wastewater treatment plants can be
significantly improved and emissions of the greenhouse
gas N2O (a by-product of denitrification) can be
avoided.
As well as the greenhouse gas
carbon dioxide (CO2), which has been the subject of much
public debate, the less well known nitrous oxide (N2O,
also known as ‘laughing gas’) also plays a key role in
climate change. As with CO2, a steep rise in atmospheric
concentrations of nitrous oxide has been registered
since the start of industrialization. Although the
concentration of carbon dioxide in the atmosphere is
about 1000 times higher than that of nitrous oxide,
nitrous oxide is 300 times more powerful in terms of its
greenhouse gas effect than carbon dioxide.
In contrast with CO2, the
increase in atmospheric N2O concentrations is due only
in small part to the combustion of fossil fuels. By far
the greatest proportion of the N2O released by humans
results from the excessive use of nitrogenous nutrients
(such as nitrate/NO3-), which are converted into the
greenhouse gas N2O by natural microbial processes
(nitrification and denitrification).
One of the key concerns of
the European Water Framework Directive (WFD), which came
into force in 2000, is the reduction of
nitrogen-containing nutrients in waterbodies. One
approach is to avoid or optimize the use of nitrogen
fertilizers in agriculture. Another approach is to
improve wastewater treatment technologies...

Mr. Mohan wants to purify his
biogas:
In our biogas plant the CH4
content is 60%.Now we want to utilize this gas in our Lime
kiln. Before taking into lime kiln we want to increase
the CH4 content.
I request to send the details
of the available technology to increase the CH4 content in
biogas. Your early reply is highly appreciated.

Mr. West wants to know about
phosphorus removal:
I hope I say this correctly,
"it takes 7.14 mg/l alkalinity to remove 1 mg/l ammonia."
Example, if I want a 100 mg/l alk. at the effluent, and the
ammonia that I want to remove is 25 mg/l, then the influent
alk. will need to be 278.5 mg/l. (25 x 7.14 + 100)
If phosphorus removal is done
by alum addition what is the calculation for this? At
times increasing the alum feed to remove the phosphorus
causes the effluent pH to drop too low and not enough
phosphorus has been removed. I add soda ash (by guess
and by gosh) to get the required phosphorus removal and to
maintain a proper pH.
I want to take the guess work
out of it. What formula is there to help me with having to
add alk. to get the phosphorus removal by alum addition?
Is that as clear as mud?
