In this post, I would like to focus the effect of photocatalysis, in this case represented by Titanium dioxide and UV irradiation for organic particle distribution, which is natural organic matter, represented by Dissolved Organic Carbon, humical acid. I would like to know which organic particle size in responsible for fouling of TiO2-UV membrane.
As you probably already aware, waste disposal methods had been found from ancient time. Sewers were found in the prehistoric cities of Crete and ancient Assyrian areas. Sewers built by the Romans, although at the first were mainly for carrying storm water, but in practice sewers were used to carry organic matter because of dumping refuse by the Romans, and this organic was carried along with the rainwater runoff. There are various pictures you might like about Roman’s disposal system in Lynn Wastewater treatment plant world history.
In case you have forgotten, I’d like to remind you that we passed World Water Day in 22 March. This year’s theme is “Water Scarcity”. In my previous post, indeed I put several rows talking about water scarcity and few pictures of it as an example, when it displayed several kids need water badly in the middle of dessert.
I found this magazine recently, it was on magazines.com website. This is quite interesting since it is not easy to find magazines dedicated fully to environmental condition. Here what they say: About E: The Environmental Magazine: E covers everything environmental “from recycling to rainforests,” including climate change, the state of oceans and rivers, and wildlife … Read more
On the early application of human waste disposal, nuisance and health problem always be primary effect caused by such activity. Just imagine, often the method of disposal consisted of nothing more than flinging out the content of the pots out the window!
I found this very interesting to find out, how to quantify potential loss, societal cost due to gas emission from our transportation. Let’s do the math now!
Right, I am trying to list here what I am planning to do within short time:
At the moment, I am cleaning my all membranes after TiO2-UV batch: 1 kD, 15 and 50 kD, two pieces for each.
