Bakki Shower
Bakki showers are a type of trickle filtration. Origins First developed by the Momotaro Japanese koi farm, the bakki shower attempts to simulate natures way of filtering water. Similar to a mountain stream where water cascades over rocks. Biofilms and algae grow on the rocks and feed on the nutrients in the stream, essentially filtering the water. In the case of the Bakki shower, ceramic is placed in trays and the water pumped to the top of the filter and trickles through the media, eventually flowing back to the pond. Momotaro Koi Farms developed the bakki shower with stainless steel trays. Since that time many "DIY bakki showers" have been designed with variations on them. Plastic and fiberglass boxes or crates have been used with success. In all its simplicity there is a lot of higher chemistry going on between the bio film and the water column. The biochemistry is better explained in this book : ''Biology of the nitrogen cycle'' By Hermann Bothe, Stuart John Ferg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trickle Filter
''Trickle'' is the second and most recent album from English trip hop band Olive. History Following the band's debut album '' Extra Virgin'' and a subsequent promotional tour, keyboard programmer Robin Taylor-Firth left the band. Also during this time the UK arm of record label RCA lost interest in supporting the band; as a result, Olive was dropped from the RCA roster. By this time, the follow-up album had been completed, including a cover of the 1975 UK number-one single " I'm Not in Love" by 10cc (chosen partially as an attempt to obtain better favour with RCA). However, Olive then signed with Maverick Records, after reportedly being discovered by label founder Madonna when she attended one of their concerts in Germany; initially, the band were recruited for a contribution to the soundtrack to the Madonna film ''The Next Best Thing'', and a recording contract resulted from the contact. "I'm Not in Love" became the band's contribution to the February 2000-released soun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biofilms
A biofilm comprises any syntrophic consortium of microorganisms in which cells stick to each other and often also to a surface. These adherent cells become embedded within a slimy extracellular matrix that is composed of extracellular polymeric substances (EPSs). The cells within the biofilm produce the EPS components, which are typically a polymeric conglomeration of extracellular polysaccharides, proteins, lipids and DNA. Because they have three-dimensional structure and represent a community lifestyle for microorganisms, they have been metaphorically described as "cities for microbes". Biofilms may form on living or non-living surfaces and can be prevalent in natural, industrial, and hospital settings. They may constitute a microbiome or be a portion of it. The microbial cells growing in a biofilm are physiologically distinct from planktonic cells of the same organism, which, by contrast, are single cells that may float or swim in a liquid medium. Biofilms can f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algae
Algae ( , ; : alga ) are any of a large and diverse group of photosynthetic, eukaryotic organisms. The name is an informal term for a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as '' Chlorella'', '' Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the '' Charophyta'', a division of green algae which includes, for example, '' Spirogyra'' and stoneworts. Algae that are carried by water are plankton, specifically phytoplankton. Algae constitute a polyphyletic group since they do not include a common ancestor, and although their plastids seem to have a single ori ...

Carbon Dioxide
Carbon dioxide ( chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

External Links
An internal link is a type of hyperlink on a web page to another page or resource, such as an image or document, on the same website or domain name, domain. Hyperlinks are considered either "external" or "internal" depending on their target or destination. Generally, a link to a page outside the same domain or website is considered external, whereas one that points at another section of the same web page or to another page of the same website or domain is considered internal. These definitions become clouded, however, when the same organization operates multiple domains functioning as a single web experience, e.g. when a secure commerce website is used for purchasing things displayed on a Secure website, non-secure website. In these cases, links that are "external" by the above definition can conceivably be classified as "internal" for some purposes. Ultimately, an internal link points to a web page or resource in the same root directory. Similarly, seemingly "internal" links ar ...

Waste Treatment Technology
Waste (or wastes) are unwanted or unusable materials. Waste is any substance discarded after primary use, or is worthless, defective and of no use. A by-product, by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero. Examples include municipal solid waste (household trash/refuse), hazardous waste, wastewater (such as sewage, which contains bodily wastes (feces and urine) and surface runoff), radioactive waste, and others. Definitions What constitutes waste depends on the eye of the beholder; one person's waste can be a resource for another person. Though waste is a physical object, its generation is a physical and psychological process. The definitions used by various agencies are as below. United Nations Environment Program According to the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes an ...

Fountains
A fountain, from the Latin "fons" (genitive "fontis"), meaning source or spring, is a decorative reservoir used for discharging water. It is also a structure that jets water into the air for a decorative or dramatic effect. Fountains were originally purely functional, connected to springs or aqueducts and used to provide drinking water and water for bathing and washing to the residents of cities, towns and villages. Until the late 19th century most fountains operated by gravity, and needed a source of water higher than the fountain, such as a reservoir or aqueduct, to make the water flow or jet into the air. In addition to providing drinking water, fountains were used for decoration and to celebrate their builders. Roman fountains were decorated with bronze or stone masks of animals or heroes. In the Middle Ages, Moorish and Muslim garden designers used fountains to create miniature versions of the gardens of paradise. King Louis XIV of France used fountains in the Gardens of ...
