This is the case for the Oxidation Ditch process, for example. Care must be taken to place the diffusers far enough from the boosters and calculations of oxygen transfer efficiency should consider the effects of the boosters. Diffusers should be place no closer than 20 ft (6m) from the discharge of a...

In the aeration basin of a typical wastewater treatment plant there are both organic and inorganic matter that can impair the function of fine bubble diffusers. Eventually this requires either additional energy to overcome high membrane headloss, or reducing the oxygen mass transfer to the process. The rate and type of fouling depends on whether the plant is treating industrial or municipal wastewater, as well as on the process....

Can Green Taxes save the Environment?

The UK government is looking to impose even more taxes on the working population. But these are not just taxes to create revenue; they are so called green taxes that save the environment as well. They are intended to change our behaviour and the way that we live, to make us less wasteful and conserve scarce resources for generations to come. We are consuming the planets resources at an unsustainable rate and this article will look at 3 of the proposed taxes to see if it will change anything. Green Tax No 1. To try and persuade us to drive...

Hi-tech ways to capture enough sunlight per day every day to power everything in a home or business hasn't been discovered yet. The current cost of solar panels can run into thousands of pounds, which would require the panels to produce electricity for years without maintenance in order to see a return on investment. What is needed is more grants available to people to enable...

Using Bio Diesel in your Car

Did you ever wonder what you would do if petrol went up to over £1 a litre or $3 a gallon? Well with the trouble in Iran and Nigeria, these prices are nearly a reality! Its likely that the farmers would not blockade the countries roads for starters as people come resigned to the fact that high prices are here to stay. Unfortunately, the high prices are unlikely to decrease and are becoming more and more likely with increasing tensions around the world in oil economies leading to decreasing oil supply and price volatility in the world markets. Fossil fuels...

The Wind Farm Debate

According to the Energy Saving Trust, the UK has 40% of Europe's total wind energy. But it's still largely untapped and only 0.5% the UKs electricity requirements are currently generated by wind power. Wind power is proportional to the cube of the wind's speed, so relatively minor increases in speed result in large changes in potential output. Individual turbines vary in size and power output from a few hundred watts to two or three megawatts (as a guide, a typical domestic system would be 2.5 - 6 kilowatts, depending on the location and size of the home). Uses range from...

According to the Guardian (March, 2006) the overwhelming majority of leaders at last week's European Union summit, including Tony Blair, strongly backed a revival of nuclear power as the answer to Europe's growing dependence on overseas supplies and to combat climate change. Construction of nuclear power plants declined following the 1986 disaster at Chernobyl. Lately, there has been renewed interest in nuclear energy from national governments, the public,...

Digital video is most often recorded on tape, then distributed on optical discs, usually DVDs. There are exceptions, such as camcorders that record directly to DVDs, Digital8 camcorders which encode digital video on conventional analog tapes. Digital video is a type of video recording system that works by using a digital, rather than analog, representation of the video signal. This generic term is not to be confused with the name DV, which is a specific type of digital video targeted at the consumer market. Digital video is most often recorded on tape, then distributed on optical discs, usually DVDs. There...
