TH142C3 - Process of raising shrimp without toxic gases - Google Patents

Abstract

The system and process for controlling the conditions of shrimp farming in a pond without toxic gases, which consists of the following parts: - Earthen pond (1) lined with HDPE (High Density Polyethylene) plastic containing water for shrimp farming - Underwater pump (2) located in pond (1) for sucking sediment and water from pond (1) connected to the filter (3) using a flexible pipe - Filter (3) for filtering sediment from the water coming from pump (2) and sending the filtered water to the treatment pond (4) - Treatment pond (4) located higher than the shrimp farming pond (1) for treating the water sent from the filter (3) using ozone gas, then recirculating back to pond (1) through an overflow pipe - Ozone generator (5) for producing ozone gas to feed into the treatment pond (4) in the process of controlling the conditions of shrimp farming in this system. The process begins with monitoring the water conditions in pond (1) that are initially introduced into pond (1) and periodically during normal shrimp farming operations. Whenever the water condition monitoring results, such as Hydrogen Sulfide, Ammonia, Nitrite, etc., deviate from the optimal conditions for shrimp, the system is activated to immediately and consistently activate its various components. The steps are as follows: A submersible pump (2) draws water and sediment from pond (1) to the filter (3), the filtered water is sent to the treatment pond (4), while the ozone generator (5) produces ozone and sends it to the treatment pond (4). The water in pond (4) is monitored periodically until it is in suitable condition for shrimp farming. The treated water in the treatment pond (4), with residual ozone not exceeding 0.01 ml/L, is returned to pond (1) through the overflow pipe. This system and method allow for control of variables related to pond bottom conditions, water conditions, and pathogens in the pond that can harm the shrimp.

Claims (2)

1. The system and process for controlling the conditions of shrimp farming in a pond without toxic gases, which consists of the following parts: - Earthen pond (1) lined with HDPE (High Density Polyethylene) plastic containing water for shrimp farming - Underwater pump (2) located in pond (1) for sucking sediment and water in pond (1) connected to the filter (3) using a flexible pipe - Filter (3) for filtering sediment from the water coming from pump (2) and then sending the filtered water to the treatment pond (4) - Treatment pond (4) located higher than the shrimp farming pond (1) for treating the water sent from the filter (3) using ozone gas, then recirculating back to pond (1) through an overflow pipe - Ozone generator (5) for producing ozone gas to feed into the treatment pond (4), which is the process for controlling the conditions of shrimp farming in this system. The process begins with monitoring the water conditions in pond (1) that are initially fed into pond (1) and periodically during normal shrimp farming operations. Whenever the results of water condition monitoring, such as Hydrogen Sulfied, Ammonia, Nitrite, et c., deviate from the optimal conditions for shrimp, the system is activated to immediately and consistently activate the various components of the system, which are as follows: A submersible pump (2) draws water and sediment from pond (1) to the filter (3), the filtered water is then sent to the treatment pond (4), while the ozone generator produces ozone and sends it to the treatment pond (4). The water in pond (4) is monitored periodically until it is in suitable condition for shrimp farming and then returned to pond (1) through the overflow pipe. 2. The system and process for controlling the conditions of shrimp farming according to claim 1, in which the treated water and returned to pond (1) will have residual ozone of no more than 0.01 milligrams per liter.
