What is one challenge associated with the nutrient recovery process?

The challenge associated with the nutrient recovery process can be significantly tied to the cost of chemical treatments. In many cases, the technologies and chemicals used for extracting and recovering nutrients, such as phosphorus and nitrogen, can be expensive. These costs can arise from the need to maintain specific chemical reactions, manage byproducts, and ensure that the recovery process is efficient and effective. Additionally, the economic feasibility of nutrient recovery projects often depends on balancing these costs with potential benefits, making financial considerations a major hurdle in implementing nutrient recovery systems. This financial aspect is critical, as it can influence the overall viability and sustainability of nutrient recovery initiatives in sewage treatment facilities.
