We at Calix hope you all had a great Christmas, New Year and Lunar New Year!
With the hot summer months in Australia, we also devote this newsletter to our products and R&D that may be particularly topical here. The production of rotten egg gas from sewers and waste waters increases with temperature, and its effects on sewer infrastructure and also potentially human health are significant. We have introduced a new formulation for PROTECTA-Mag to make it even more durable in protecting vital sewer assets. We also cover our freshwater lake remediation project in Kuala Lumpur at its half-way mark – even more topical given the recent news of the Darling River fish kills in Australia due to nutrient run-off causing blue-green algae and loss of dissolved oxygen. We are progressing as fast as we can on developing this solution – it is clearly needed.
We look forward to 2019 in what will be an important year in our development. In addition to the
We wish you all the very best for the New Year and thank you for your support and interest in Calix.
⇑ A great start of the year for the AQUA-Cal team at the Shrimp Masters Conference in China (Zhuhai) with our partner Honlex Jones - Exchanging ideas on the latest technologies & trends on aquaculture, the fastest growing food-producing sector.
After outlining six sustainability challenges over the next decade, this series
will dive deeper into each of these challenges in a dedicated special feature.

With a constant flow from 2 other pump stations, a sewer pump station at North East Water had suffered a significant amount of acid damage, with its concrete surface visibly pitted.
Calix coated the asset with the new formulation of PROTECTA-Mag, which allows better control of hardening time and improves adherence to the concrete walls. The new formulation proved very resistant to wear in

Australia, there is a growing pressure to control odorous emissions.
Emissions of odorous compounds increase during the summer months, not only because of increased H2S volatility (evaporation) but also because of an increase in anaerobic bacterial activity, as oxygen is less soluble at higher temperatures.
It is recommended that plant operators measure H2S more regularly in the summer months, and step up
