Waterlogged Pressure Tanks. A waterlogged pressure tank is caused by the confined space within the tank having an improper ratio of water to air (too much water, not enough air). Given the physical characteristics of water (incompressible), this condition causes the pressure to fluctuate rapidly and the well pump to go on and off too much.
Antioxidant activity of chitin, chitosan, and their derivatives can be attributed to in vitro and in vivo free radical-scavenging activities. Antioxidant effect of chitin, chitosan, and their derivatives may be used as functional ingredients in food formulations to promote consumer health and to improve the shelf life of food products. Structure of Chitin, what it is made of
Chitosan has a number of commercial and possible biomedical uses. It can be used in agriculture as a seed treatment and biopesticide, helping plants to fight off fungal infections. In winemaking it can be used as a fining agent, also helping to prevent spoilage.ommercial chitosan is derived from the shells of shrimp and other sea crustaceans, including Pandalus borealis, pictured here. Chitosan is produced commercially by deacetylation of chitin, which is the structural element in the exoskeleton of crustaceans (such as crabs and shrimp) and cell walls of fungi.
