Wastewater treatment technology for shrimp, fish and aquaculture ponds

[Water treatment technology for shrimp and fish ponds] - Currently, the aquaculture industry is considered one of our country's strengths. Each year, it is estimated that the amount of aquatic products such as shrimp and fish exported to the world is quite high. Therefore, recently, fishermen have focused on developing the aquaculture industry, leading to the alarming problem of environmental pollution caused by this industry.

To solve the environmental pollution caused by the shrimp and fish farming industry, E&C Environmental Technology Joint Stock Company provides a number of wastewater treatment solutions for the aquaculture industry. Let's learn about the solution processing process in the article below

Aquaculture industry wastewater treatment technology helps increase production for people

Harmful effects of wastewater from shrimp farming and fish farming industry on the environment

In recent years, the industrial-scale shrimp and fish farming industry has been increasingly developing, and farming techniques have also been improved by people. However, people's awareness of protecting the surrounding environment has not been promoted, so environmental pollution is becoming more and more common, causing a significant impact on the environment as well as human health. people. Specifically:

Sludge: The amount of excess food and feces emitted by shrimp and fish is not properly treated. After a long period of accumulation, it causes aerobic conditions, a foul smell, and the production of many toxins. different harm. Shrimp and fish are starved of oxygen and die en masse, but the carcasses are not treated promptly, affecting other beneficial organisms.
Wastewater: Wastewater from the farming process and wastewater from the processing process are discharged directly to neighboring areas. The amount of excess antibiotics in the aquaculture process, containing many toxic substances, solid metals, domestic wastewater of the people in the aquaculture area, wastewater from cleaning processing tools... is not clear. is processed, followed by waste pipes into neighboring areas, directly affecting humans and livestock

Some Water treatment technologies for shrimp and fish ponds

There are many methods of treating wastewater in the aquaculture industry: shrimp farming, fish farming, below we would like to offer some safe treatment models.

Biological wastewater treatment technology
1/ Wastewater treatment model using biological systems

Considered the safest method when using biological species, beneficial bacteria produce a number of substances that can decompose impurities and excess food during the process of raising shrimp and fish. Depending on the type of bacteria, the decomposition process is different

Aerobic process: Is the process of decomposing substances in the presence of oxygen by aerobic organisms
Anaerobic process: Occurs thanks to anaerobic organisms in the sludge layer when there is no oxygen
Wastewater treatment model using animal systems
In some models, customers often raise clams and oysters in shrimp and fish ponds. The purpose of this method is to use those animals to destroy plankton living on the bottom of the lake

2/ Wastewater treatment technology using physical methods

Physical method is the process of using materials to remove large impurities. This method is often used in the early stages of wastewater treatment. The materials used are:

Use screens: To remove trash, leaves, and large impurities
Sedimentation tank: To remove smaller sized impurities and moss
Filter material: Handles harmful germs, bacteria, and microscopic organic impurities.
3/ Wastewater treatment technology using chemical methods

Chemical wastewater treatment technology involves introducing some chemicals into shrimp and fish tanks. These chemicals will decompose substances in the water. However, this method is not recommended. Because users need to put a sufficient amount of chemicals into the water source to avoid affecting the shrimp and fish in the tank. If it's too little, it won't be effective. If it's too much, it will cause chemical excess, affecting the development of aquatic products. Even pollutes the water environment

Advantages and disadvantages of wastewater treatment technology in shrimp and fish farming industry

Low technology system operating costs
Easy to install, easy to disassemble and transport
The system has many capacity levels, suitable for different needs, suitable for many types of aquaculture models, large and small.
However, the wastewater treatment technology system in the aquaculture industry has the disadvantage of requiring users to have high professional qualifications and the construction area must be large enough for the system to operate best.
Depending on different aquaculture models and different conditions, the choice of wastewater treatment system is different. E&C Vietnam Environmental Technology Service Joint Stock Company is committed to providing and installing wastewater treatment models to suit all customer needs. Ensure the system operates best, providing safe and hygienic water sources, increasing shrimp and fish farming productivity, and bringing high economic efficiency to people.
