Shrimp Farm Wastewater Treatment by Biological Methods

Shrimp Farm Wastewater Treatment by Biological Methods   During the past ten to twenty years, shrimp farming has became a major income producer for a number of countries in Asia and South America. Shrimp farm wastewater treatment has become a major issue. In fact, shrimp farming will be one of the top aquaculture industries in the near future. The demand for shrimp for continue to grow and it has become a major export for countries such as Ecuador, Thailand, Vietnam, Indonesia, and Brazil. Along with this economic growth has come environmental problems. In particular shrimp farm wastewater, a type of agriculture wastewater, is a major concern in shrimp farming. Shrimp farm wastewater causes two main concerns; it affects the quality and quantity of the shrimp and it causes environmental problems in future growing seasons. In the future, shrimp farm wastewater treatment will become important industry for continued growth of shrimp farming. Shrimp farming problems are generally caused by: High Shrimp Density – Shrimp farms typically have 200,000 – 400,000 post larvae shrimp per hectare (about 2.5 acres). With this high of a density of shrimp organic wastes accumulate rapidly. These wastes include; excess food, shrimp waste, and exoskeleton material. These wastes sink to the bottom of the shrimp farm and...
