dairy lagoons

There are two types of lagoons. One is the anaerobic lagoon and the other is the aerobic lagoon. Anaerobic lagoons are earthen containers sized to provide biological treatment and long-term animal waste storage. They are larger than manure storage basins, which do not provide significant biological treatment or long storage periods. On the other hand, anaerobic lagoons are smaller than aerobic lagoons, which are designed to provide a higher degree of treatment with less odor production. Most dairy lagoons are anaerobic. The advantages of anaerobic lagoon systems are: manure can be handled hydraulically with water flushing systems, sewer lines, pumps, and irrigation equipment; high nitrogen reduction minimizes the land area required for liquid effluent disposal, high degree of stabilization reduces odors during land application, and long-term storage at low cost.
