Making Process of Humic Acid

Humic acid is a biological organic matter and importantly an abundant earth resource, which can be extracted for use in agricultural, environmental and medical fields. The production of humic acid is an extremely complex yet extremely useful process. In this article, we will explore how to produce this valuable organic substance.

The production process of humic acid is usually divided into two methods: biological method and chemical method. Biological methods usually produce humic acid through natural, microbial fermentation. Chemical methods usually synthesize humic acid through chemical reactions. Among the two methods, biological methods have received more attention because they are more economical, environmentally friendly, targeted and slow-release.

The production process of biomethod is a complex process. First of all, the source of raw materials is key. Use natural organic materials or industrial wastewater with less chemical fertilizers as much as possible, and use microorganisms such as Escherichia coli, yeast, thermophiles, sulfate reducing bacteria, and molasses to ferment to produce humic acid. Secondly, it is also important to adjust environmental factors. For example, adding an appropriate amount of salt, acidity, nutrients, etc. must ensure their balance during the preparation process to ensure the optimal growth environment for microorganisms so that microorganisms can produce humus to the maximum extent. Also pay attention to the control of the bioreactor. In this way, the yield and quality of humic acid can be well guaranteed.

Although the chemical method to prepare humic acid is highly efficient and does not require biological adjustment, it often requires the use of a large amount of chemical raw materials, the discharge of waste water, waste gas, and waste residue, and the addition of a large amount of energy, additives, and agar, which is not as environmentally friendly as the biological method.
