Enhancing water quality, oxygenation and biofilter efficiency through nanobubble technology

Maintaining optimal water quality in recirculating aquaculture systems (RAS)  is paramount for ensuring fish health and growth. Water quality directly affects fish metabolism, disease resistance, and feed conversion efficiency. Poor water conditions can lead to increased stress, susceptibility to diseases, and inefficient nutrient utilization, resulting in higher operational costs and lower yields. Dissolved oxygen (DO) and ammonia (N-NH4) are two of the key factors that affect water quality and fish welfare. Therefore, efficient water oxygenation and biological nitrification are crucial for fish growers and constitute some of the most important operational challenges and costs.

In comparison to fine bubbles and traditional aeration or oxygenation systems, Moleaer’s Nanobubble Technology offers several additional benefits. Their enhanced gas transfer efficiency means that they can achieve higher levels of dissolved oxygen with less gas input, making them more energy-efficient and cost-effective. Furthermore, the unique properties of nanobubbles facilitate the removal of contaminants and impurities from water and improve water clarity.
