Issue 45/2013 - When Water Meets Chemistry – Kemira's innovative water treatment solutions are unveiled

On November 12, at the 2013 China International Water Treatment Chemicals Technology and Application Exhibition held at the Shanghai World Expo Exhibition and Convention Center, Kemira of Finland, a global pioneer in the field of water treatment technology, displayed a series of advanced products, technologies and solutions
.

At present, due to various reasons such as different water sources, excessive dosing of coagulant during pretreatment, and serious corrosion of water supply pipelines, excessive iron/aluminum content in membrane feed water has become increasingly common
.
With conventional scale inhibitors, the reverse osmosis membrane can only be "passively" accepted until fouling
.
Kemira's KemGuard 1350C is a phosphorus-free green scale inhibitor specifically for reverse osmosis systems
.
It can not only effectively prevent various mineral salt scales encountered by the reverse osmosis system, but also has a high resistance to metal scales such as iron / aluminum, which can greatly alleviate the iron/aluminum fouling problem that causes the majority of reverse osmosis users headaches, help users avoid and reduce the reverse osmosis membrane fouling caused by the unstable water quality or pretreatment, thereby prolonging the water production cycle, reducing the cleaning frequency, improving economic benefits, and is an ideal upgrade product
containing organic phosphorus/polycarboxylic acid scale inhibitors.

Deep sludge dewatering technology is another highlight of
Kemira's exhibition.
In 2004~2010, the average annual growth of the total treatment capacity of China's sewage treatment plant was about 2.
72 billion cubic meters; according to the calculation of 7.
5 tons of sludge with a moisture content of 80% generated by 10,000 tons of sewage, it is estimated that the sludge volume in China in 2015 will be 3.
5 times
that of 2004.
In this context, sludge reduction is imminent
.
Kemira's second-generation sludge dewatering solution provides a comprehensive range of technologies such as source burden reduction pretreatment technology, high-performance chemical conditioning technology and subsequent safe and hygienic disposal technology, which can reduce the sludge moisture content to less than 60%, opening up more ways
for sludge disposal.

In addition, Kemira showcased high-quality chemicals for water treatment, comprehensive applications for raw water treatment/odor control, and green chemicals and innovative solutions for industrial water treatment
