Whether you are part of the management of a biosolids treatment plant or a mere observer, it’s important to know how to properly store biosolids… not sewage sludge, but biosolids, which are ready for land application and various other usages. Biosolids is a critical part of a sustainable environment that we’re all trying to achieve for the good of the earth. Imagine using domestic waste to boost crop and vegetation growth.
If you think about it, this process has been around for centuries. Our forefathers have used the stone-age process of treating waste and even manure to be used as organic fertilizer, though that term has not been around back then. For the storage of biosolids, here are the important things you should take note of:
Nutrients not loss
Storing biosolids must not affect nor eliminate its nutrients. Biosolids have an enormous quantity of nitrogen, phosphorus, and potassium. These three nutrients are important for a healthy soil that will yield better crops. The treatment process that biosolids go through triggers the release of these essential nutrients. Storing biosolids should be done in a location that has the right temperature—neither too cold nor too hot—because any inconsistencies could break down the nutrients.
If you are going to store biosolids, make sure that the odor will be contained in the storage unit. Biosolids has a rotten and putrid smell that pollutes the air and makes it harder for people near the storage unit to breath normally. Unless it is a leak-proof and airtight container and storage unit, you would be hard-pressed to suppress the odor that is a major challenge for treatment plants and its managers. When storing biosolids, don’t just find a storage unit that could contain the odor. Rather, transfer the biosolids in a container that would help stop the odor from spreading.
The reason why biosolids are becoming accepted and even welcomed in communities is because of its quality. It is the only fertilizer available in the market that does not use chemicals for its preservation. Many farmers have turned to biosolids because it is cost-efficient (it costs less) and it is healthier for the soil and the plants. Storing biosolids means you are responsible for the maintenance of its quality. As long as the quality is assured and maintained and there are no opportunities for pathogens to be present or multiply, there should be no reason why you cannot store biosolids for future use.
