New technology in water filtration for shrimp farming received science and technology award

(Baonghean.vn) - The project "Self-cleaning water filtration pump system for shrimp farming on fine sandy land" by Mr. Hoang Van Hoi was awarded the Third Prize - Award for scientific and technological innovation of Nghe An province.

Shrimp farming is a sustainable aquaculture industry in some coastal districts and towns in Nghe An. The average farming area is about 2,200 hectares per year. However, the negative impacts of waste discharge and climate change cause the water pumped into the ponds to be polluted, which is one of the causes of shrimp diseases.

The project "Self-cleaning water filtration pump system for shrimp farming on fine sandy land" by Mr. Hoang Van Hoi - an aquaculture engineer in Nghe An, belonging to Aquaculture Technology and Services Company Limited is considered a new technology to clean water sources for shrimp farming.

This water filtration method will make the water source from the sea to the pond cleaner through a filter system. The filter system and all the pipes are buried underground. When the sea water rises to the surface, it will seep into the filter pipes to pump back to the pond.

Mr. Hoang Van Hoi - the author of the project explained: "This water filtration system is designed with PVC pipes of diameter 90 assembled together, with many small gaps on the body of the pipe. After digging the hole, use coarse sand to cover the bottom, then place the filter on top, continue to cover with coarse sand to fill. When the water rises, it will seep into the coarse sand, through the small gaps on the surface of the filter pipe, seep into the pipe core. This process limits small organisms, plankton larvae, shrimp, crabs, clams... which are things that often cause diseases in aquaculture ponds when pumping water directly from the sea."

Besides the clean filtered water source, the advantages of this water filtration system are that it is not washed away by sea waves because it is completely buried underground; water can be collected all day because it does not depend on the tide; large water flow due to water filtration by gravity and pump pressure; does not take up space in the farm because the filtration system is installed on the coast.

For many shrimp farmers, this is an effective way to pump water for shrimp farming. Mr. Nguyen Cuong - a shrimp farmer in Dien Trung commune, Dien Chau district said: "This method of filtering water for shrimp farming is quite convenient. Currently, many farmers in Dien Trung have used this method of filtering water instead of pumping water directly from the sea because it requires less pond treatment and limits the use of disinfectant chemicals."

The self-cleaning water filtration model for shrimp farming on fine sandy land with its safe and practical advantages will help shrimp farmers reduce costs in treating ponds and lagoons, and limit the outbreak of diseases.

This is the result of research and creativity of Mr. Hoang Van Hoi - an aquaculture engineer in Nghe An; the project "Water filtration pump system for self-cleaning shrimp farming on fine sandy land" has just been awarded 3rd prize in the Nghe An Province Science and Technology Innovation Award./.
