#Article
The role plants play in purifying water is one of nature’s most ingenious and benevolent designs. This function, termed as an ‘ecosystem service’, delineates the benefits humans garner from ecosystems. A plethora of flora varieties possess the phenomenal ability to cleanse water through their natural biological and chemical processes.
##Process of Natural Water Purification
Plants achieve purification of water through root filtration, phytodegradation, and rhizofiltration. Let’s delve into these processes.
###Root Filtration
This primarily involves the plant’s roots acting as natural filters, absorbing pollutants from the water. The roots retain the harmful contaminants, yielding filtered water.
###Phytodegradation
Phytodegradation involves the plant metabolizing contaminants and breaking them down into harmless substances. During the process, the plant absorbs the pollutant and transforms it into a less-toxic compound through its metabolic activities.
###Rhizofiltration
Rhizofiltration is a water remediation technique that encompasses the absorption and adsorption of contaminants by plant roots. The contaminants are later bioaccumulated and metabolized within the plant’s tissues acting as natural cleansers.
##Types of Water Pollutants that Can Be Purified by Plants
Plants have the remarkable ability to purify both organic and inorganic pollutants, including heavy metals. Each of these pollutants affects water health and quality differently and require targeted purification methods.
###Organic Pollutants
Organic pollutants might include materials such as oils, fats, and detergents that plants can metabolize into smaller, less harmful materials. Certain plants possess the ability to remove up to 98% of organic pollutants from water.
###Inorganic Pollutants
Inorganic pollutants, such as nitrates and phosphates, are also able to be cleansed from the water by plants. These pollutants can be absorbed and used by plants in their cellular processes. With the right plants, the removal of inorganic pollutants can reach up to 80%.
###Heavy Metals
Plants use a unique technique called phytoextraction to remove heavy metals from water. They extract and bioaccumulate these heavy metals in their tissue, effectively trapping them and removing them from the water.
##List of Plants That Help in Purifying Water
There is a wide spectrum of plants that excel in purifying water. Some of them include Cattails, Water Hyacinths, Duckweed, and ReedS. These plants are easily accessible and relatively easy to manage.
Each plant species provides its unique set of benefits when it comes to water purification, turning seemingly stagnant or polluted bodies of water into healthy, vibrant ecosystems.
