With , they can do their job without lowering oxygen levels so much that fish die. • Plants – During daylight hours, plants provide oxygen through Photosynthesis. Supplemental aeration will not only help maintain the plants during this time, but also provide adequate oxygen so fish do not suffer as a consequence. Aeration also will buffer your fish from rapid drops in oxygen due to large plant or algae die offs. • Feeding – Fish use up to 10 times the amount of oxygen while feeding as they do at rest.
Therefore, the more oxygen you have in the water, the more often fish can feed. The more they can feed, the larger and faster they can grow. Parkson offers several types of aerators, each with specific advantages. The VariOx jet system offers independent control of aeration and mixing. This is ideal for biological nutrient removal applications where tank zones need to operate continuously in complete mix mode with aeration varied or turned off completely. If reduced maintenance is a priority, the FRP construction of the jet aerators offers years of operation with no scheduled maintenance or replacement of the FRP components. Operational cost considerations drive the choice of aeration floor.
These include aerated static pile size, labor availability, and requirements for leachate management. POG aeration floors are most successful at facilities with relatively short pile lengths, low cost labor, and modest requirements for leachate management. In-floor aeration system maintenance includes flushing and removing solids, and occasional repair of damaged surface floor elements caused by wheel loaders. These floors need to be easily accessible for pressure washing, scooping or suctioning to remove solids.
