Things We Learn From The Biosolids Treatment Process



Many people don’t realize that the presence of biosolids in the market actually lowers the cost of food products and crops and vegetation. As an alternative to commercial-grade fertilizers, biosolids are more economical for agricultural use and even for land application on forestlands and reclaimed mining sites.

And yet, many communities still frown at the presence of biosolids treatment plants in their midst, not knowing that biosolids are the oldest form of fertilizers and we’re basically just going back to a period where our environment is sustainable.

Here are a few things we need to know about biosolids and how they are being used:

That biosolids are categorized into three classes

Biosolids are classified into three: Class A biosolids have almost non-detectable levels of pathogens and the material complied with strict standards regarding metals, odors, and vectors. Class A EQ biosolids do not only meet, but have exceeded all Class A pathogen reduction metals and VAR requirements by the US EPA. On the other hand, Class B biosolids are treated, but still contain higher levels of pathogens compared to Class A biosolids.

That biosolids are a smart alternative to chemical fertilizers

Instead of using commercial-grade and chemical fertilizers, farmers, ranchers, and gardeners can opt to use biosolids as an alternative. Centuries ago, our forefathers used an untreated version of biosolids for fertilizing their soil and their land. We are basically going back to the natural order of life—when our waste could also be used to sustain crops, vegetation, flowers, plants, and even food products.

That biosolids are a natural source of minerals and nutrients

In order to enrich your soil, you have to boost it with nutrients such as potassium, phosphorus, and nitrogen. Biosolids have an abundant source of these three nutrients because these are naturally contained in the wastewater sludge that is treated to become biosolids. The treatment processes enable these three nutrients to multiply.

That products grown from biosolids are safe for human consumption

The common misconception about biosolids is that sewage sludge is being used directly to boost the nutrients of the soil where the food products grow. This is completely false because the treatment that sewage sludge undergoes completely breaks down and removes every level of pathogen and contaminant from the material. What it produces is the safest form of fertilizer there is in the market. It is, in fact, safer to be applied in crop-producing soil than chemical fertilizers ever will be.
