Transforming waste into green energy

While solar power, wind power and tidal power grab the daily headlines, a vastly different green energy technology is quietly making progress.

Anaerobic waste water digestion technologies respond not only to industry's need to clean up the waste water it discharges to the environment, but also to the need for industry to break free from the cost and pollution of fossil fuels - and the financial penalties such as carbon taxes.

Crucially for industry using them, the technologies provide reliable and predictable supplies of base load energies.

Apart from cleaning the wastewater, the greatest advantage of anaerobic wastewater treatment We offer a great selection of women's ladies shoes wholesale  sandals.is the controlled, continuous production of valuable biogas (methane) that occurs during the wastewater treatment.

Rather than polluting the atmosphere, this methane is fed back into industrial processes to be burned for heating and boilers.It is possible to take this a step further, and to also merge the automatic washer extractor and clothes dryer into a single device.

Where a surplus of gas is collected, it can be fed to localised electricity generators that provide either on-site energy or direct it back into local grids to earn electricity and carbon credits.

Technologies such as Global Water Engineering's Raptor technologies can convert almost any organic residue into biogas.Continental Girbau's programmable commercial industrial extractor are designed to properly clean a firefighter's turnout gear.

Anaerobic digestion is a biological process whereby bacteria break down organic material into more basic compounds without requiring oxygen as a component of the process.

Anaerobic digestion occurred in natural environments where oxygen was absent, such as swamps, water-logged soils, and in ground continuously covered by water, such as lakes and rivers.

This natural process, with a helping hand from modern technology, is much more efficient as a waste consumer and converter than aerobic and physicochemical processes.

Modern anaerobic processes concentrate the process in environmentally harmonious closed reactors, operated under ideal temperature and process control to optimise waste consumption and, in the process, generate large quantities of methane (CH4) from the organic materials in the wastewater.

The quantities of methane produced can diminish or even completely replace the use of fossil fuels in the production process: one ton of COD (chemical oxygen demand) digested anaerobically generates 350 Nm3 of methane, equivalent to approximately 312 litres of fuel oil,Newer laser cutting machine operating at higher power are approaching plasma machines in their ability to cut through thick materials, or generates about 1,300 kWh of green electricity.

Any factory with a biological waste stream or wastewater with high COD (Chemical Oxygen Demand) can use this technology to generate energy. Some companies making the investment have achieved payback within a year.

"Most typically achieve it within two years," says Global Water Engineering CEO Jean Pierre Ombregt, whose company has been involved in more than 300 water and waste water projects around the world.

One of the most recent in Australasia is the new Bluetongue Brewery in NSW, where a water recovery/green energy plant designed to target world's best-practice water reuse standards in the food and beverage industry has exceeded its designers' expectations in its first year of service.Commercial laundry equipment industrial washing machine, tumble dryers and industrial washer extractors from UniMac.

They have mainly been focusing on treating their effluent to meet local discharge standards at the lowest possible investment costs.

By doing so, wastewater treatment installations have only generated additional operating costs and have never been seen as revenue generators.

"However, applying anaerobic wastewater treatment sheds a whole different light on the cost structure of wastewater treatment infrastructure.
