EESS APB Site Visit and AGM – with fresh beer ☺
On Saturday 6th January 2018, EESS organized an Asia Pacific Brewery (APB) site visit. Around 20 of us gathered at the APB visitors center. Shortly after the vivid video about the origins of tiger beer in Singapore, we proceeded to the site visit to understand about the brewing and bottling process.
For the brewing process, the tour guide allowed us to smell the raw malt, roasted malt, hops essence and yeast. Wow, the roasted malt looks so black and smelt like a coffee bean! Next, we stepped into the brewing house, where the secrete of beer making was revealed in front of us: crushing and boiling the malt, separating malt liquid and spent grain, adding hops, adding yeast, filtering out yeast, and adding CO2. We then moved to the bottling process house which housed Asia’s first automated bottling system. Cans were lined up in rows, transferred, packed into carton boxes and shipped out on wooden pallets.
At the end of the tour, we were treated specially and nicely with a buffet lunch companied with fresh bear, followed by the EESS AGM. Thank you so much EESS for organizing this! Looking forward to upcoming site visits!

Meet ‘n’ Mingle Night
On 21st November 2017, EESS organized a Meet ‘n’ Mingle Night at the Tea Party Café in NUS to facilitate networking sessions for the members to share their experiences in the environmental engineering-related sectors. Six EESS members, Mr. Joseph Hui, Mr. Raajeevan Kandiah Sanmugaratnam, Dr. Lim Chiak Hwee, Dr. Lu Gang, Dr. Huang Zhi and Dr. Guo Huiling were invited to share about their work experiences. These speakers came from ranging professions ranging from air quality and water pollution, research , acoustic engineering as well as the education sectors.
The dialogue session allowed us to have a more in-depth understanding of what is it like to work in the various environmental engineering-related fields and I found the session on acoustic engineering to be very interesting as it was my first encounter with this field apart from my understandings in books. We would also like to thank the invited speakers for taking the time to share their experiences with us, thank you!

Behind-the-scenes of S.E.A Aquarium
On 24th October, EESS organized a technical visit to the S.E.A aquarium. The guided tour provided EESS members on insights regarding the Life Support System, the backbone of the aquarium.
We had the opportunity to visit the food preparatory area (for the fishes of course!) and also gained access to the divers’ area where we overlooked the largest tank in the aquarium. Our guide, Mr Saravanan explained that the credit to the water quality goes to the Life Support Systems team who works round the clock to maintain the extensive treatment systems comprising of fractionators, filters and disinfection units. Likewise, divers also have the responsibility of cleaning all tanks every morning to remove debris and food residual.
This technical visit was indeed an interesting one in which we learnt about water quality management in an aquarium, marine pollution and various aquatic animals.

Technical Site Visit to Lower Seletar Waterworks (LSWW)
This site visit was an eye opener and an enriching experience for me. The plant manager and senior engineer gave us a comprehensive sharing on each of the water treatment processes. Basically, the main purpose of LSWW is to cater for the treatment of raw water from Lower Seletar Reservoir. The water is treated chemically first, followed by a pressurised ultra-filtration system and electrochlorination system.
The system that particularly interests me is the on-site hypochlorite generation system which is used for disinfection. Sodium hypochlorite can be generated by running an electric current through the salt water in an electrolyzer to trigger electrolysis. The main advantage of on-site hypochlorite generation system is that it can be easily stored and transported when it is produced on-site in comparison to the dangerous transportation, handling and storage of chlorine gas cylinders for chlorination. Hence, this technology enables the safety of the operators and community.
