Biologický filtr

Why is filtration important? What is biological filtration? How to build a biofilter? These characteristics confer robustness to the process. In other words, the process has the capacity to maintain its performance or rapidly return to initial levels following a period.

The term biological filters or biofilters used in wastewater treatment includes all the processes that combine biological purification through attached growth with the retention of suspended solids. A trickling filter is a type of wastewater treatment system. This provides a biomass with a. A biological filter is a natural filtering system consisting of helpful bacterial colonies that, through a cycling process, convert pollutants in water to harmless nitrate. Nitrate is nitrogen, therefore this cycling process is also referred to as the nitrogen cycle, or cycling a tank. A basic understanding of a biological filter is necessary.

In this article, we will talk about biological filtration and why it needs to be present in any filter device. Later, I will tell you about the best biological filter media for aquariums. First, I will tell about the most popular benefits that come with using a biological filter media. And as you will soon learn, that’s a good thing! A live filter is referred to as biological filtration, and it can make all the difference to the water quality in your aquarium.

The next stage after the removal of the solids is the reduction of dissolved waste such as ammonia and nitrite. The biological filter is an area devoted to the support and concentration of bacteria needed to break down the waste. The waste from the fish is the start of the nitrogen cycle in.

The filter plant consists of a bed of random or modular plastic media through which the effluent percolates. Tohle překvapení mě čekalo při čištění filtru. Nitěnky zpracovávají kal z akvacitu celkem efektivně.

Asi se tam dostali z živým krmením z rybníka a daří se jim. Trickling filters are one of the oldest types of biological filters. Any surface in an aquarium which comes in contact with the nitrosoma bacteria that you created when you cycled the tank is part of your biological filter. The lack of effective biological filtration is probably responsible for the deaths of more fish than any other cause.

The particular dissolved compounds controlled by biological filtration are very toxic to fish even at low concentrations. Bacterial growth occurs in porous surface areas. For instance sponges, rock and gravel can act as substrate for bacteria. The biological aerated filter (BAF) has a 2-3m deep bed of relatively small size filter media, to provide a high surface area, on which to grow a biomass. The filter bed is submerged and a settled wastewater is pumped either upwards or downwards through the filter.

A blower sends air through a diffuser at the. Biological aerated filtering. Before we review different biological filter media, let’s take a closer look at the microbes that make biological filtration happen in our aquariums.

Keeping the water in your aquarium clean is crucial to the wellbeing of your fish. Our varied range of aquarium filters are designed to help you achieve this, and are suitable for tanks of varying capacity. Our Internal filters and external hang on filters provide filtration for small to medium size tanks and are a very economic and efficient.
