Which of the following describes a drawback of nutrient recovery?

Nutrient recovery is a process that allows the extraction of valuable nutrients, such as nitrogen and phosphorus, from wastewater, which can then be reused in agricultural applications or other industries. However, one significant drawback of this process is its technical complexity and the need for specialized equipment.

Implementing nutrient recovery systems often requires advanced technology that may not be available in all treatment facilities. These systems can involve sophisticated chemical processes, membrane technologies, or reactor designs that need to be tailored to the specific types of wastewater being treated. The need for skilled personnel to operate and maintain this equipment further adds to the complexity of nutrient recovery systems. Therefore, while nutrient recovery has clear environmental benefits, the technical hurdles can pose challenges for widespread adoption and operation.
