This article will guide you through the most effective pig farm environmental treatment method we consider today. Using a combination of environmental treatment methods in the barn with Organic carbon NEMA1, treating exhaust gas after the exhaust fan with a filter system, treating waste with a dry manure press and treating wastewater with a biogas tank.
In the process of raising pigs, environmental treatment is always one of the biggest challenges for farms, especially concentrated farms with large numbers of pigs. If not handled promptly and effectively, it will not only affect the health of the animals but also affect the surrounding environment, negatively affecting sustainable farming for the farm.
Step 1: Treat the environment in the barn with organic carbon NEMA1
Organic carbon NEMA1 is one of the products that is rated as extremely effective for treating the environment in the barn. Organic Carbon is extracted from organic sources, has the ability to decompose organic compounds, deodorize and treat pollutants in the farming environment. Use Organic Carbon NEMA1 to treat waste at the source with the following advantages: Fast effectiveness after spraying, organic products do not affect livestock, increase the efficiency of bio gas tank treatment, increase the quality of organic fertilizer.

How to use:
- Automatic spraying system: The automatic system developed by JVSF is applied in livestock farms for medium and large farms. When using the system, it will automatically spray water containing Organic Carbon to cover the surfaces of the concentrated waste farming floor in a short time. Set according to fixed spraying times, helping to handle odors quickly and effectively, saving costs.

- Using manual spraying: Usually applied to small farms. Various spraying tools can be shoulder-mounted electric sprayers, pressure sprayers…
Benefits:
- Deodorize the barn, treat toxic gases with odors such as H2S, NH3.
- Improve air quality.
- Enhance resistance, improve animal health.
Step 2. Treat exhaust gas after exhaust fan with filter system
Exhaust fan is one of the important equipment used to circulate air and remove odors in cold barns (the most popular pig barns today). However, exhaust gas from exhaust fans still contains many dust particles, bacteria and foul odors from the barn. For effective exhaust gas treatment, a filtration system can be installed after the exhaust fan.
Filter systems:
- Mechanical filtration: Only uses filter plates to catch dust particles and suspended matter in the exhaust gas. This system will not reduce odors to the outside.
- Mesh filtration: Uses stacked mesh panels to increase the contact area of the exhaust gas with water. With this system, it will have the effect of reducing emissions into the environment because part of it is absorbed by water.

Benefits:
- Reduces bad odors from the exhaust fan.
- Prevents dust from the fan from escaping into the surrounding environment, helping to improve the quality of the surrounding air.
Step 3. Waste treatment with a dry manure press
In pig farms, cleaning manure with Water is widely used to create a large amount of wastewater. In wastewater, organic compounds account for 70-80% including cellulose, protein, amino acids, fats, carbohydrates and their derivatives in manure and leftover food. Most organic substances are easily decomposed, inorganic substances account for 20-30% including sand, soil, salt, urea, ammonium, salt, chloride, SO42-…
As we can see, the amount of organic matter in manure is very large, to effectively treat it, we can use a dry manure press. The dry manure press operates based on the principle of filtering wastewater into manure and then pressing the manure to remove water and form dry manure.

Benefits:
- Creates organic fertilizer with high economic value, used for agriculture.
- Increases the processing efficiency of the Biogas tank, increases the processing capacity of the tank, limits the amount of sludge accumulated at the bottom of the tank.
Step 4: Treat wastewater with a biogas tank
Wastewater from the barn Livestock wastewater is also a serious source of pollution. The characteristics and composition of livestock wastewater contain many easily decomposable organic impurities as shown by the parameters of BOD, total N, total P and pathogenic microorganisms. To effectively treat wastewater, a biogas tank can be used. A biogas tank is a wastewater treatment system based on the biological decomposition process of microorganisms.
The product of the biogas tank system consists of two main parts: biogas and sludge. Sludge is a type of organic fertilizer. It has high nutritional content and is a clean organic fertilizer. Waste from Biogas tanks usually has a dry matter content of 6-10%.
If this amount of sludge is not collected, it will reduce the depth of the pond, leading to a reduction in treatment efficiency and sedimentation time of the ponds.

Benefits:
- Effectively treat wastewater from livestock pens.
- Produce biogas that can be used as fuel.
- Improve the environment and protect water resources.
Results discussion
Combining environmental treatment methods in organic carbon pig farms NEMA1, exhaust gas filtration systems, dry manure presses and bio gas tanks is an effective way to improve the farming environment, reduce pollution and protect the health of livestock. These methods, when combined, form a comprehensive treatment chain, not only helping to treat odors and treat wastewater so as not to affect the environment but also creating useful products from waste, contributing to the sustainable development of the livestock industry.
