Use of Plants in the Treatment of Tannery Wastewater

Plants are used for wastewater treatment, which is a natural and ecological method.It is an alternative to conventional methods for wastewater from various sources.Because they take advantage of the capabilities of nature and naturally occurring adapted plants, they are characterized by their ability to carry out many processes and transformations that they carry out themselves and those occurring within them, such as in the aerobic and anaerobic zones of the root zone.Microorganisms present in the soil provide additional support for the vegetation, supporting the treatment processes.Due to the rising cost of wastewater treatment in typical wastewater treatment plants, the hydrophytic method is becoming competitive due to the low expenses associated with its operation and control.This method also works well for industrial wastewater, including tannery wastewater.Wastewater from the tanning industry is troublesome to manage and can also be a source of chromium, while studies have confirmed the possibility of treating such wastewater on plant beds.
