Global Warming: Conclude yourself

It’s really challenging or either quite confusing for those whose background is not related to global warming or air pollution. I am Environmental Engineer, but I am really not major on this. This begins when I watched A Unconvenient Truth, presented by Al-Gore, when at the movie he talked about global warming, and the problem is this movie was shown on the class which has nothing to do with global warming, Environmental Emerging Contaminants. Amazingly, I keep thinking about the impact that may occur because of global warming, from what he said.

Obviously, what the movie was telling that, we have been emitting such huge amount of CO2 annually, and that cause the increase of solar radiation trapped by this gas, thus results in an increased temperature, and rise the temperature. The effect, ice melting, just like what had happened in Canadian Arctic recently as a result of global warming.

Environmental Engineering Roots

Environmental engineering is a relatively new profession with a long and honorable history. The title of “Environmental engineer” interestingly was not used until 1960s in US, when academic programs in engineering and public health schools broadened their scope and wanted to have special and accurate title to describe their material and courses. Thus, the differentiation between environmental engineer and public health or other engineering part hopefully become more clear.

Outline of Introduction of Environmental Engineering Course

This is the outline of the class of Introduction of Environmental Engineering. Oke, let’s get straight to the point. Several topics that I am going to explain here are as follows:

1. Environmental Engineering Roots and History
2. Environmental Impact Assessment
3. Risk Analysis
4. Water Pollution and Water Quality
5. Water Supply and Water Treatment
6. Wastewater Treatment and Collection
7. Sludge Treatment and Disposal
8. Nonpoint source water pollution
9. Hazardous Waste and 3R (reuse, recycling and recovery)
10. Air Pollution and Air Quality.

Seems TiO2+UV do not have effect toward HA removal

I almost finished my current short term goal. I did some tests, using membrane 50 kD, 15 kD. For both, I used same comparison, one using TiO2 coating plus UV, the other one without them, just naked membrane. Seems that percentage removal of TOC between TiO2+UV membrane and just naked membrane, better for naked membrane. Wow.. I keep wondering why..
