Efficient Filtration Technology Can Save Money and the Environment


Larox filters and filtration solutions help customers meet growing 
environmental requirements and tightening environmental legislation. 
Inaddition to savings in energy and water, the amount of waste and other 
process emissions can be significantly reduced. 

According to European Chemical Industry Council (CEFIC), “The Chemical Industry
actively seeks to develop innovative manufacturing processes that minimize 
the burden on the environment” (www.cefic.be). There are a number of global, 
national, industrywide or company level sustainability programs and projects
all aiming at the same goal: reducing environmental impact of the operations. 
This same goal is supported by Larox's filtration solutions for the separation
of solid and liquid substances.
 
“Efficient solid-liquid separation technology leads to both economical
and environmental benefits,” says Mr. Reiner Weidner, Vice President
for Larox Corporation. “Our customers acquire Larox technology either because 
they have high quality, capacity and productivity objectives, or because they 
need to satisfy environmental regulations and legislation. ”

Reducing Environmental Impact

“Environmental impact depends on many variables,” Mr. Weidner continues, 
“It depends on the industry, application, product and process itself. 
Larox filters are used for a wide variety of applications which means the
environmental benefits vary as well.

Larox's filters and filtration solutions are designed in such a way that in 
most of the processes they help to achieve significant savings in energy and/or
water consumption. Efficient filtration also leads to better quality waste
water, thus reducing the environmental burden.”

Due to tightening environmental legislation and requirements, demand for
Larox's filtration technology is growing. However, as Mr. Weidner points out,
investing in a new technology is not always necessary, “Major environmental
improvements can be achieved through modernizations and process optimization
projects. Larox has solutions also for these customer needs.” 

LESS WASTE

Environmental Success Story 

In 2007, Larox supplied a Larox C Series Automatic Pressure Filter to Stora
Enso Fluting mill located in Heinola, Finland. Larox's solution for the green
liquor dregs filtration enabled the plant to meet the increasingly stringent
waste handling requirements. “Due to the efficient dewatering process of the
filter, our dump volume and waste transportation costs were reduced by 70%. 
The cake moisture dropped to below 20%, i.e. the dry solids in the filter cake 
are now over 80%,” said Stora Enso's power plant manager Mr. Erkki Vuori. 

SAVING ENERGY AND WATER

Environmental Success Story 

Larox C Series Automatic Pressure Filters have proven to bring major economical 
and environmental advantages when replacing traditional centrifuge-based
technology in the production of modified starch. 

In a case study presented by Mr. Jin Shuren, Chairman of the Sugar Alcohol
Committee under the China Starch Association, centrifuge and Larox's filtration
technologies were compared and results calculated. 

The study concluded that, in addition to many other environmental benefits,
Larox filter's energy consumption was 84% lower than that of the centrifuge, 
and water consumption was reduced by 90%!

It was calculated that the economical benefit with the Larox solution amounted
to approximately US $ 410,000 in savings for a plant with a starch capacity of 
30,000 t/annum.
