池塘

The natural 吸收 and adsorption capabilities of zeolite ( as molecular sieve )make it the perfect candidate to promote the ongoing health and sustainability of aquatic ecosystems. In these environments, zeolite serves three primary functions: to remove toxic levels of nitrogen and ammonium ions from aquarium waters; to provide oxygen-enriched air; to purify tank waters (Mumpton 1985 & 1999).

Hargreaves (1998) 报告说，鱼类排泄物和沉积物通量增加了水生环境中的氮含量。如果水位超过池塘的同化能力，水质会因含氮化合物（如氨）的积累而恶化。当这种情况发生时，科学家会观察到鱼的鳃损伤、增生、不育、发育迟缓和死亡率（Mumpton，1985）。

Studies have proven that zeolite’s ion exchange properties control nitrogen content and can provide an effective means for ammonium removal (Mumpton, 1985 & 1999). In fact, studies have found that up to 97 percent of ammonium produced in aquatic systems can be removed by zeolite ion-exchange (Mumpton, 1985). As an added advantage, 沸石处理 are low cost and the mineral itself has a high tolerance to changing temperatures and chemical conditions (Mumpton, 1985).
