Although we know that biosolids is safe for food production as it is now being used for crops, gardening, and other food manufacturing processes, we are in the dark about the treatment it has to go through before reaching the state of viability.
What do you know so far? That biosolids is the by-product of the post-processed sewage sludge that came from domestic wastewater after it went through a wastewater treatment facility? That it has many nutrients needed by crops and plants in order to grow? That it is being used in replacement of chemical fertilizers?
To fully grasp the magnitude of biosolids’ role in the environment, we must begin to understand the treatment process it has to go through. The treatment of biosolids actually begin before the domestic wastewater is treated in a facility. In many instances, it is required that wastewater undergoes pre-treatment procedure to remove the hazardous contaminants in them before undergoing treatment in sewage treatment facilities. In turn, these treatment plants monitor and filter the incoming of domestic wastewater to make sure that there are no harmful contaminants in them. This also ensures that the wastewater has recyclable properties and that it is compatible with the treatment process.
When the wastewater reaches the plant, a biological process will cleanse the wastewater and separate the solids. This solids will then be digested or stabilized through separate processes. The aim of this step is to remove the pathogens or any contaminants that could harm the soil where the biosolids will be used.
The treatment and processing of the solid materials will then turn it into biosolids, which can be recycled as fertilizer. When applied properly, biosolids can improve the soil structure and stimulate the growth of plants, crops, and other such products.
It’s stupefying how come we’re just beginning to understand the importance of biosolids in the environment. For years, farmers and gardeners have been recycling biosolids to reduce the need and the use of chemical fertilizers. They use biosolids to promote the growth of agricultural crops, fertilize gardens and parks, and even reclaim mining sites. On crop production, there’s a certain amount only needed for the application. That is why the application of biosolids is generally restricted and the plant nutrients are released slowly throughout the growing season, so that they can be absorbed more efficiently.
Now that there is the beginning of understanding about the treatment processes of biosolids, we can rest in the knowledge that it is safe for crop production and it is beneficial for the environment.
