The research results related to the problem of removing ammonia nitrogen from transport containers for the transport of fish.

It was found that the survival of aquatic organisms during transport affected by a number of factors, chief among which is the accumulation of waste products. Released into the water the fish waste products and final products of oxidation lead to a change in the active response of the medium. The sharp change in pH may lead to loss of fish.

We have investigated the removal of ammonia nitrogen by different materials to determine the most effective sorbent.

For the implementation of the task were studied cation-exchange resin KU-2×8 in the hydrogen form, cation-exchange resin KU-2×8 in sodium form, zeolite sorbent FLAM and activated carbon AG-3. It is shown that the most effective sorbent was zeolite sorbent FLAM. It was determined value of the sorption capacity under static and dynamic conditions, including in the presence salts of hardness. We are solved the problem of sorbent FLAM regeneration.

Keywords: ammonia nitrogen, zeolite sorbent FLAM, sorption capacity, ion exchange.
