cow manure, as a common organic raw material, you not only make bio organic fertilizer from cow manure, but also make bio liquid cow manure fertilizer. To make liquid biofertilizer from cow waste, You can achieve by following these steps: dehydration, precipitation and filtration of impurities, disinfection, nutrient ratio, and anaerobic fermentation.
How to dehydrate the liquid in cow waste?
Using cow manure dewatering machine can effectively extract liquid components from fresh cow manure. There are two types for sale in YUSHUNXIN: spiral extrusion type and inclined screen type. Because the water content of fresh cow dung is usually 60%-80%, it is most appropriate to use a spiral dehydrator. After dehydration, the water content of cow dung is 20%-30%. It can be made into powdered or granular biofertilizer.

How to remove impurities from cow dung wastewater?
In order to obtain pure cow dung liquid bio fertilizer, you need to remove a large amount of impurities contained in it. First, you can build a sedimentation tank to precipitate the visible impurities in it. Then, use a filtration device to remove other impurities in the cow manure wastewater, such as silt, grass clippings, etc.
How to kill pathogens in filtered cow dung wastewater for making liquid biofertilizer?
The filtered cow manure liquid contains some harmful substances such as pathogens or insect eggs. Using a sterilization device can be of great help.

How should you ferment liquid cow dung into biofertilizer?
Before anaerobic fermentation, by using the batching tank, you can add the biological agents and related ingredients to the cow dung liquid according to the proportion. The stirring device of the YUSHUNXIN fermentation tank can fully mix the material. Then control the temperature in the fermenter at 25-35℃. During the anaerobic fermentation process, you should turn on the stirring device on 1-2 times a day for 15-30 minutes each time to ensure uniform fermentation. After 7-10 days, the fermentation is over.
Secondary chelation Process
After the above steps, you can also add nutrients such as nitrogen, phosphorus, and potassium or water-souble humic acid to the mixture to increase the nutritional content of the liquid biofertilizer.
The above is the complete steps to manufacture liquid biofertilizer from cow waste. There are whole sets of bioliquid fertilizer unit on sale in YUSHUNXIN.
