A wet dry filter using a drip plate to disperse the water over bio-media.
a water purifier in which water flows slowly, or trickles, over media not submerged but held in a tray or chamber, meant to facilitate attachment and growth of nitrifying bacteria.
A type of Bio-filter in which water to be purified trickles over the media held in a tray or chamber not submerged in water. This increases the amount of oxygen available to the bacteria, promoting Nitrification.
A wet and dry filter where water is dripped over plastic gravel like media which is also exposed to the open air. This promotes good bacterial growth.
This form of a wet/dry filter provides primarily filtration. Water is dripped over some media which is also exposed to the air. This promotes very efficient nitrification. The water may drip from a spray bar or drip plate. The medium may be small pieces of plastic, DLS, or anything else which will support bacteria and not easily clog.
A biological filtration system which consists of a plastic chamber with a biological filtration media. Water runs through the media, which mixes with the air, and reacts with the bacteria which serve to remove ammonia and nitrites. It is this wet / dry exchange that promotes bacterial growth.
Homemade filtration unit made from plastic scraps and carry boxes.
