biological filtration discussion

The rock is very porous and will act as a biological filter for your tank as it will contain beneficial bacteria to help breakdown fish waste. People will disagree on how much rock to use in a reef tank, but generally it is recommended to use anywhere between ½ to 2 pounds per gallon of water. Live rock must also be properly cured before any ...

Biofilter is a key component in recirculating aquaculture systems (RAS) for converting highly toxic ammonia to less toxic nitrate using nitrifying bacteria. In the present study, two configurations of rotating biological contactors (RBC)—biodisk and biodrum—were designed and fabricated for development of recirculating freshwater …

For me, the two most effective types of biological filter media have been Eheim Subtrat Pro (which are small balls of sintered glass) and Seachem Matrix (which is pumice based). Both have tremendous surface area, but even these do not completely eliminate nitrates on their own. But don't overlook the effectiveness of just plain old .

I use lava rock in filters and as a base to attach java fern and anubias plants. I have used it in filters on two small ponds and the water stays crystal clear. I bought a bag of lava rock used in barbecues and it works well. It also works in riparium planters. One of the wholesale fish suppliers highly recommend it to help remove nitrates.

The best biological filtration in a ZMAS is in the function of the desired bio-load. ... A discussion about the porosity of rock has only sense if maintaining a very limited bioload and even then, the filtration capacity will be very low due to the very limited water exchange rate in porous rock. Porosity may influence the denitrification ...

Biological filtration systems2.1. Types of filtration systems. Filtration is a major process to produce safe drinking water in a DWTP. The primary purpose of filtration is to remove particulate matter from the filter influent passing through a porous media such as sands, anthracites, and granular activated carbons (GAC).

Biological filtration uses "good bacteria" to digest waste and balance water. The same principles are used in aquariums, septic tanks, and many other applications. Afterwards, the water is sent through several other systems to completely purify it and make it exceptionally safe for drinking. Here are the details about how these …

Abstract. Addresses key issues related to optimization of biological filters for multiple objectives, namely, simultaneous particle or floc removal and biodegradation of organic compounds, on a number of source waters and process designs (direct filtration, post-sedimentation, following ozone, etc.). Published in 2001.

Limitations for the filtration are: It must fit on a table 1.6m x 0.60m. The tank (or tanks) are yet to be decided upon / designed. So, in a biological filter system what would you love to have? This can be for; 1. Filtration capacity 2. Great for a refugium type environment 3. Interesting Go! Matt (Thanks in advance)

Biological filtration is a natural process by which beneficial bacteria, called nitrifying bacteria, metabolize ammonia and nitrite in the water. The bacteria convert ammonia, which is toxic to fish, into nitrite, which is less toxic, and then into nitrate, which is relatively safe at lower levels. Biological filtration works in conjunction ...

The only differene between biomedia and rock is that the biomedia is typically more porous and doesn't take up space in the display. And no, biomedia is not a nitrate factory in that they produce unwanted nitrates. Whatever nitrates they produce will come from what you are putting in the tank.

The optimal temperature for nitrosomas and nitrobacter replication is somewhere between 78-80 degrees Fahrenheit. An aquarium will "cycle" at 65 degrees, it will just take longer to do so. Even if I'm setting up a "cold water" tank, I put a heater in for the cycle period (fishless). Edited May 14, 2021 by tonyjuliano. 2.

The sponges are for particulate filtration. You don't need anything in the filter except the water movement. The Nitrogen Cycle starts with ammonia, and the plants take up the ammonia directly, so you end up with a low level of Nitrate.
