One milligram per liter of ammonia-nitrogen is equivalent to 1.22 mg/L of ammonia., Confusion on this can result in reporting an ammonia violation when, in fact, there may not be a violation at all. The next article will deal with the other forms of nitrogen that we are concerned with in the wastewater field: nitrate, nitrite, and organic nitrogen.

Alkalinity or buffering capacity is a key consideration in ,wastewater, treatment especially if you require ,ammonia, oxidation. AOB/NOB activity consumes approximately 7.1 mg alkalinity as CaCO3 per mg ,ammonia, fully oxidized. Other processes in the ,nitrogen, cycle can release alkalinity back into the water.

12 Things You Need to Know to Garden Using Aquaponics

In aquaponic gardening water is pumped from the fish tank into a grow bed that is filled with an inert growing medium. The medium is home to colonies of beneficial bacteria and composting red worms. The bacteria converts the toxic ammonia from the fish waste first into nitrites then into nitrates, and the worms convert the solid waste into vermicomost.
