Abstract

Ammonia is one of the problems of the aquaculture industry that causes by aquaculture activities, which can be enriched water body. Ammonia, even in low concentrations may also have negative effects on the tissues and physiological factors of Rainbow trout. In this study, the combination of physical absorbents with algae biofilms in a sinusoidal bioreactor was used. Adsorbents were placed in a polyvinyl chloride mesh in a bioreactor. For ten days Zayndr medium was injected into the system to form biofilms on the absorber. Then the storage volume of biorector was replaced by Rainbow trout breeding farm effluent in Heraz. Every 12 hours, water factors were measured and recorded. In this study, the coal, the Coral shell and the Steel wool that were covered with algae-bacterial biofilms and provided a suitable bed for physical and biological removal were used. The initial concentration of Ammonia in the bioreactor was 2. 5 mg/L and each of the media was tested separately. The rate of Ammonia reduction in, Lilaki coal, Coral shell and Steel wool has been 91. 5%, 82. 1%, and 78. 8% during the 72-hour test period, respectively. The efficiency of Ammonia removal in the bioreactor was based on the complement that the interactions of media with biofilm in the direction of physical, chemical and biodegradation, which yielded optimum efficiency, compared to similar systems at the shorter time.
