Oxygen is one of the main parameters concerning fish health welfare. In intensive farming it is important that adequate levels of oxygen can be maintained at all times in the fish tank to optimize feeding, welfare and growth. Medium Head Oxygenators are normally the preferred choice in our designs. In this way we do not need an extra pumping step and are still able to supply the oxygen in an efficient way.

Pressure swing adsorption (PSA) is a technology used to separate some gas species from a mixture of gases under pressure according to the species’ molecular characteristics and affinity for an adsorbent material. It operates at near-ambient temperatures and differs significantly from cryogenic distillation techniques of gas separation. Specific adsorptive materials (e.g., zeolites, activated carbon, molecular sieves, etc.) are used as a trap, preferentially adsorbing the target gas species at high pressure. The process then swings to low pressure to desorb the adsorbed material.

ACE utilizes several bio-filter types, depending on the type of fish produced, the climatic conditions and the dimensions of the farm building. Trickling filters are normally used when evaporative cooling is targeted or when the fish species has low tolerance for carbon dioxide. In other cases, moving bed bio-filters (MBBR’s) may be the bio-filter of choice.
