Environmental engineering is truly phenomenon, with the never ending story to remediate pollution and our natures. I remember the time when I got accepted at Department of Environmental Engineering, ITS, I was very happy as being a part of environmental engineer family was my expectation. But of course I had to work hard to pass the exam to go to that college, which was called UMPTN, similar with SAT test in US.
Environmental impact assessment: brief overview
Almost all aspects involving alteration of natural environment now require that the impact, interactions and effects of every designed structures towards natural habitat or ecosystems be considered and assessed for any kind of activities. In US, this was in 1970 which the principle was enacted into federal law.
Environmental Engineer as profession
The general objectives and golas of colleges adn universities are to allow students to mature intelectually and socially and to prepare for careers, especially for environmental engineering profession that are rewarding. The chosen vocation is ideally an avocation as well. Having a job like an environmental engineer, we should take it as an enjoyable job and approaching it with enthusiasm, even after experiencing many of the ever-present bumps in the path. Be love and enjoy is the key, not only for environmental engineering field but apply to other kind of jobs.
Environment Sites and SEO
If you are wondering SEO is, it is Search Engine Optimization. What it has something to do with environment? Well, I make this post to encourage those environmental sites webmasters to build sites that SEO-friendly.
Ecology: its term and concept
Definition: ecology
Ecology is the science of the relationships between organisms and their environments, defined by thefreedictionary. More explanation provided by wikipedia, as ecology is the scientific study of the distribution and abundance of living organisms and their interactions each other. Ecosystems, as part of ecology, is interdependent populations of organisms interacting with their physical and chemical environment. Ecosystem interactions can also include more than two species.
Gel Filtration Chromatography: protein fractionation
Well known as GFC, this is usually used to fractionate protein. It is based on molecular size, when larger particles will eluete first, followed by smaller molecule. In my experiment, I will employ this to fractionate humic substance. There are several points from which the method in using this GFC. GFC is included in Size Exclusion Chromatography. Size exclusion chromatography (SEC) is a chromatographic method in which particles are separated based on their size. When an aqueous solution is used to transport the sample through the column the technique is known as gel filtration chromatography.
Further Effect of Photocatalysis toward organic particles size distribution
I have mentioned several information on my post about the effect of photocatalysis process to particle size distribution. Now in this post, I would like to a little bit further explain it more as I am really courious about this.
Public health: short history
Industrial revolution had changed everything including lifestyle, mindset throughout industry world as well as on sanitation condition. The sanitation condition was very sad, at least this was expressed in the Report from the Poor Law Commissioners on an Inquiry into the Sanitary Conditions of the Labouring Population of Great Britain. Implicitly this was represented by philosophy of Edwin Chadwick (1800–1890) who viewed the improvement of drainage, housing and water supply as an essential national economic good, as it prevented the early deaths of working men. The sanitation condition at that time was described:
Photocatalysis effect for organic particle distribution
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.
Wastewater treatment plant: the beginning
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.
