According to foreign media reports, thanks to the latest research results of biochemists and microbiologists from the University of Ghent, Belgium, people will be able to significantly increase the amount of energy extracted from waste water, such as thermal energy, biogas energy, and electrical energy. Recently, they are working on a pilot project with DC Water in Washington, DC, USA. Since the waste water from the bathroom and kitchen contains a lot of organic substances, they are very promising energy sources. If you want to achieve true self-sustaining wastewater treatment, then the trick is to separate the organic matter inside, so that the wastewater can be reused, and organic matter can be used to generate bio-energy.
At present, most wastewater treatment plants treat microorganisms by “eaten†organic substances. However, this method will form particles and then deposit on the bottom of the tank, so its extraction volume is not very satisfactory. It is reported that the current process can probably recover 20% to 30% of organic substances. Dr. Francis Meerburg, a member of the project, said that their goal is to continuously increase the amount of organic matter captured by bacteria.
The team found that they could achieve the goal of increasing the amount of organic material extracted by letting the bacteria “hungryâ€.
Prof. Nico Boon explained that they regularly “starve to death†some bacteria and then contact the wastewater with these bacteria but get organic substances.
This method can increase the amount of organic material extracted to 55%, which is a very large increase for the current level. The team calculated that organic matter of this size is sufficient for the electricity needed for wastewater treatment.
Prof. Siegried Vlaeminck stated that this new method will reduce the cost of public energy and also bring more energy-balanced treatment processes to wastewater treatment plants. The professor pointed out that although this process of theirs cannot solve the problem of climate change, it can still play a little help anyway.
The high quality one can be used kill Caligus and sea lice, but no harm for Salmon and water, can used in fresh water and sea water. The low quality one are harm for Salmon, only used to kill fly, ants, cockroach and so on.
The application rate for this use is 0.1 to 0.2 mg/liter as a bath treatment.
The product should be keeped in well-ventilated place and free from exposure on sunshine & raining.
