From plants into biofilters – Naava's acceleration process. Plants are the eye-catching piece of Naava, but to understand the air purification technology, it's better to dig a bit deeper to what's inside. Every pot in Naava acts as an efficient biofilter which Naava's air flows through.

The biofilter works by housing bacteria which converts ammonia from the fish waste into nitrates for plants to grow. This is done in a two step process called Nitrification. Firstly, the nitrosomonas bacteria converts the ammonia to Nitrites after which the Nitrites are then further converted to Nitrates by the nitrobacter bacteria.

Plants are not normally used for the primary biofilter in aquaculture systems. They do however provide a very good sink for the nitrates produced by a well functioning biofiltration system. The marriage of recirculating aquaculture systems and hydroponics is known as aquaponics .

A biofilter for control of air pollutants consists of one or more beds of biologically active material, primarily mix-tures based on compost, peat or soil. Filter beds are typically 1 meter in height. A conceptual design of an open biofilter is shown in Figure 1 and an illustration of an existing, enclosed biofilter is shown in Figure 2. Contami-

biofilter. It can be the trickling filter in the wastewater treatment plant, or horizontal rock filter in a polluted stream, or granular acti-vated carbon (GAC) or sand filter in water treatment plant. Biofil-ter has been successfully used for air, water, and wastewater treat-ment. It was first introduced in England in 1893 as a trickling filter

Biofilters are an odor treatment technology that utilizes biological processes as the treatment mechanism like biotrickling scrubbers.Biofiltration utilizes naturally concurring microorganisms that grow on media to oxidize odor and air emission compounds to carbon dioxide, water, biomass, and other benign by-products such as chloride and sulfate.

Secondly, biofilter is something specific in the world of ponds and fishtanks, something that you have here to a great degree, but the plants aren't part of it. While plant roots have a fair deal of surface area a single clay pellet may actually have more surface area than a large plant, its counterintuitive but a reality.

Biofilters, like all other hydroponic walls, are planted with plants that have already been started in a greenhouse, so the result is immediate. As with all living landscapes, die off and disease do sometimes occur, so regular maintenance is necessary.

The biofilter should be covered simply because the sunlight will cause moss and other microbiological plants to start colonizing the biofilter. This can lead to fouling and reduced efficiency of the biofilter which will be seen in elevated levels of ammonia in the system.

Plants are an essential component of biofilters. Without plants, the performance of stormwater biofilters is much poorer. Both plants and microbes serve multiple roles in biofilter function (Figure 1). Importantly, plants and microbes are inseparable, as most microbes are supported in the zone around plant roots. Plants also provide additional ...
