And anyway, here is a brief interview with him.

Majari: “Hi, Wahyu! You are December’s Author of The Month! How do you feel about that?”
Wahyu: “Hi, Majari! Of course I feel so glad and surprise too!”

Majari: “Great! Anyway, can you tell us in a nutshell what the membrane technology are all about? Any advantages that it may have compared to prior technologies?”
Wahyu: “Sure, basically membrane is a separation technology. The components will be separated based on size and shape, using pressure and semipermeable membrane. Separation using membrane need less energy and less chemical additives.”

Majari: “Have the technology already been in Indonesia?”
Wahyu: “Yes, it has. It has been used for water purification process.”

Majari: “Can you tell us more about water purification? What exactly the membrane do in that process?”
Wahyu: “The membrane act as a filter to water impurities, such as suspended particles, organic material, even bacteria and virus, depend on type of membrane we use.”

Majari: “So you’re talking about making all the water purification process into one single membrane filtering??”
Wahyu: “Water purification consist a number of stages: sediment filter to trap particles including rust and calcium carbonate, activated carbon filter to trap organic chemical, then RO filter which trap carbon, metals (As, Hg, Pb, etc), even virus and bacteria; depend on size of the pores, and then second activated carbon filter to capture chemicals not removed by reverse osmosis filter, but it’s optional, and finally ultra violet lamp for disinfection any microbes that may escape the reverse osmosis filter.”

Majari: “Ohh.. so some of the traditional equipments may be substituted with membrane and the whole process will be better?”
Wahyu: “Yes, because by using membrane; in this case the RO membrane; we can remove particles up to 1 angstrom. It’s a small unit for particles, I think”

Majari: “Emm.. in the article you’ve mentioned about the hemodialysis process with membrane.. Can you elaborate more about that?”
Wahyu: “Hemodialysis is a process that is used to help people with kidney failures. The membrane acts like a human kidney. It filters the waste product in the human blood like urea.”

Majari: “Wow.. that’s interesting.. Anyway, can you tell us what is your next article? Maybe you can give us a bit info about it.”
Wahyu: “Hmm… actually in the past 3 days, when I studied for my chemurgy final exam, I read about biohydrogen. I was interested in that topic. So, I will find out all about it, and then write you all fellow readers an article, hehehe.. just wait..”

Majari: “OK, then.. And, last but not least.. What are you going to do with the prize?”
Wahyu: “Well, I will go to a restaurant and spend the money to buy a lot of foods!”

Congratulations, Wahyu! The prize is yours! Happy eating then!
