Wastewater Technology Fact Sheet - Denitrification Filters

Davco denitrification filter. Wastewater enters a downflow filter over weirs along the length of the filter bed on both sides. Filter effluent is conveyed from the bottom of the filter over a control weir into a clear well. Backwashing is required at regular intervals. Backwashing typically involves air scouring and backwashing with air and water.

Could an ocean of ammonia exist on another planet? - Quora

Answer (1 of 2): Almost certainly not in the sense I think you mean, but there is an equivalent. The problem is that the creation of heavy elements always creates a huge amount more oxygen than nitrogen, while several orders of magnitude more hydrogen is present from the primordial times. The net...

chemistry - Ammonia planets - Worldbuilding Stack Exchange

Ammonia, -45 kJ/mol. Propinoic acid, -510 kJ/mol. Methane, -75 kJ/mol. Glycine, 1430 kJ/mol. Thus the overall reaction has (45 + 510) < (1430 - 75) which implies it will not be spontaneous, with a net endotherm of about 800 kJ/mol. I believe this is a bit under half the endotherm of photosynthesis on Earth. Share.

Do Aquarium Plants Need a Filter? (Is it really necessary?)

Plants absorb ammonia in the aquarium and use it as a fertilizer.

What Does a Coalescing Filter Do & How Does a Coalescer Work?

A coalescing filter is a device used to separate vapors, liquids, soluble particles, or oil from some other fluid through a coalescing effect. The coalescing effect is the coming together of liquid aerosols to form a larger whole which is easier to filter out of the system due to increased weight. The filter consists of several progressive ...

Granular Activated Carbon Filtration and Nitrification

The GAC filters (#7­p;#9) entered into the same pattern as filters (#1­p;#6) in ammonia specification and nitrite formation, except that they did so in a much shorter time frame. The swift appearance of nitrification may be related to the GAC temperature (daytime, 30 to 31°C) due to hot summers in South Texas (max. 92 to 98°F).
