Quality improvement of fishery water using natural zeolite and dynamics of adsorption of hydrological toxicants

The adsorption capability of the natural mineral zeolite of domestic origin, on chemical parameters in water used for the intensive breeding of the Rainbow Trout was investigated in practical and laboratory conditions. It was established on the grounds of an analysis of the obtained results that there is a statistically significant adsorptive power and selectivity of zeolite towards: ammoniac (p<0.01), nitrates (p<0.01), nitrites (p<0.05), and total hardness of water (p<0.05). The applied zeolite contributed to the improvement of the ambient conditions in the trout pond, and it also had a positive ecological effect on the filtration of hydrological toxicants of the pond water output.
