Integrated Aqua-Vegeculture System. The Integrated Aqua-Vegeculture System (iAVs),also informally known as Sandponics, [1] is a food production method that combines aquaculture and horticulture (olericulture). [2] It was developed in the 1980s by Dr. Mark McMurtry and colleagues at North Carolina State University including Professor Doug ...
Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.
The first step of nitrification in the biofilter consumes alkalinity and lowers the pH of the system. [10] Keeping the pH in a suitable range (5.0-9.0 for freshwater systems) is crucial to maintain the health of both the fish and biofilter. pH is typically controlled by the addition of alkalinity in the form of lime (CaCO 3) or sodium hydroxide ...
A biofilter is a bed of media on which microorganisms attach and grow to form a biological layer called biofilm. Biofiltration is thus usually referred to as a fixed–film process. Generally, the biofilm is formed by a community of different microorganisms (bacteria, fungi, yeast, etc.), macro-organisms (protozoa, worms, insect's larvae, etc ...
The Integrated Floating Cage Aquageoponics System (IFCAS) was developed as an aquaculture-horticulture based on the concept of integrated farming system approach firstly in Bangladesh in 2013 to produce fish and vegetables in floating condition where waste materials (fish feces and unused feed) from fish culture dissolved in the pond water and settled on the bottom mud are used for vegetables ...
Trickling filter. A trickling filter is a type of wastewater treatment system. It consists of a fixed bed of rocks, coke, gravel, slag, polyurethane foam, sphagnum peat moss, ceramic, or plastic media over which sewage or other wastewater flows downward and causes a layer of microbial slime (biofilm) to grow, covering the bed of media.
Integrated multi-trophic aquaculture. Blue mussels (Mytilus edulis) cultivated in proximity to Atlantic salmon (Salmo salar) in the Bay of Fundy, Canada. Note the salmon cage (polar circle) in the background. Integrated multi-trophic aquaculture (IMTA) is a type of aquaculture where the byproducts, including waste, from one aquatic species are ...
K1 MBBR carrier with biofilm. Moving bed biofilm reactor (MBBR) is a type of wastewater treatment process that was first invented by Professor Hallvard Ødegaard at Norwegian University of Science and Technology in the late 1980s. [1] The process takes place in an aeration tank with plastic carriers that a biofilm can grow on.
