Every year, India uses over 1 billion pounds of pesticides to control weeds and other pests. Although necessary for agricultural management, pesticides have the potential to damage groundwater and surface waters, both of which are important sources of drinking water.
Certain pesticides can be successfully removed from water using reverse osmosis systems, with an activated carbon filter. The semi-permeable membrane removes some dissolved pesticides, while the activated carbon filtration medium absorbs other pesticides and their volatile chemical components.
What are pesticides?
A pesticide is a substance that is applied to the environment to eradicate or manage pests. There are numerous varieties, each with a different application. They are designed to be sprayed on fields to eradicate weeds and insects.
Certain pesticides, which contain chemicals to stop diseases and pests from harming crops, are used by farmers.
· Using insecticides to kill insects and stop them from devouring crops is common practice.
· Weeds and grasses are eradicated by the application of herbicides.
· Mildew and fungi are killed by fungicides.
· Additionally, they develop pest-resistant varieties of crops like corn, wheat, and soybeans.
What is Reverse osmosis?
Reverse osmosis (RO) is a process that purifies water by removing contaminants by passing it, through membranes that let water molecules pass through but not the contaminants.
How to remove pesticides using a reverse osmosis filter?
Reverse osmosis, according to the Environmental Protection Agency (EPA), has been shown to be quite effective at eliminating some pesticides, although, additional testing is needed and there is a lack of specific information on many pesticides.
Reverse osmosis can get rid of some pesticides such as:
5. TRIBUTYL POTASSIUM
Activated carbon filters used in home RO systems can remove
2. 2,4-dichlorophenoxyacetic (2,4-D)
Reverse Osmosis process for pesticide removal
The process is carried out by applying pressure on the side of the membrane, containing the concentrated fluid during reverse osmosis (the contaminated side). When enough pressure is applied, this causes the osmotic process to reverse, causing clean water to move from the side where it is concentrated (which is contaminated), to the side where it is diluted (which is treated).
The treated water is collected in a storage container after it has been processed. Pesticides that are unable to pass through the concentration side of the membrane, are removed by a wastewater filter.
Different technologies that help in eliminating pesticides from water
· All of the harmful silt, sand, and dirt are eliminated by the carbon cartridge.
· A 0.020-micron Ultrafiltration (UF) membrane removes all organic colloids, bacteria, proteins, viruses, parasites, protozoa, and pyrogens from the sample.
· All of the harmful chlorine, VOCs, PCBs, MTBE, and hundreds of other chemical contaminants, are eliminated using granulated activated carbon (GAC).
Benefits of RO Technology for eliminating pesticides
· The RO filter is very simple to install and replace.
· Greater and more rapid water flow.
· The system is flushed in the holiday mode if no water is delivered for a 12-hour period.
· Low ratio of water waste.
