Approximately 2 billion individuals globally depend on freshwater sources, such as rivers, for their domestic use and drinking needs, as stated by the United Nations. River water is susceptible to multiple contaminants, some of which might be harmful to human populations. To guarantee safety when using river water, households can exploit river water purification devices to disperse any harmful impurities.
Main Causes of River Water Pollution
- Agricultural practices: The discharge of fertilizers, pesticides, and animal waste from agricultural activities has the potential to contaminate nearby rivers and streams, causing water pollution.
- Industrial waste: Several industries release waste materials and chemicals into nearby rivers, often without adequate treatment or regulation, which results in pollution.
- Household sewage: In areas without proper sanitation systems, untreated sewage, and wastewater from homes can significantly contribute to river pollution.
- Landfills and waste sites: Incorrect disposal of solid waste in landfills and garbage dumps can produce leachate, which has the potential to pollute nearby rivers and groundwater.
- Oil and chemical accidents: Accidental spills of oil or hazardous chemicals can have devastating effects on river ecosystems, leading to contamination of water, soil, and wildlife.
What is River Water Purification System for Home?
River water purification units for homes are innovative systems engineered to offer households a cost-effective and efficient means of directly purifying water from rivers or other natural water sources. Due to variations in the type and quantity of contaminants found in river water, manufacturers offer multiple purification systems to treat river water.
A Review of the Best River Water Purification Systems for Home
It is essential to purify river water before utilizing it due to the presence of numerous impurities, including sediment, organic matter, bacteria, and viruses. Fortunately, various purification systems are available for home use to purify river water.
● Reverse Osmosis Systems
Quite often, river water is rich in dissolved solids, particulates, minerals, chemicals, and heavy metals. All these pollutants can harm the human body variedly and to distinct levels if ingested. However, with a reverse osmosis (RO) river water filtration system, the threat of these pollutants is exterminated. RO units pull out unwanted contaminants from river water using a partially porous barrier (RO membranes), thereby yielding clean, safe water.
● Ultraviolet Sterilizers
It is quite common to find microbial pollutants present in river water. To eliminate the threat of waterborne illnesses posed by these units ultraviolet (UV) sterilizers are the best option. Using UV-C light at a wavelength of approximately 254 nanometers, they exterminate every microorganism that comes into contact with UV radiation. Their role is strictly preserved for microbial disinfection; hence they are often utilized in conjunction with other purification units.
● Water Softeners
Water hardness is a common characteristic of river water due to the heavy mineral contamination that originates from nearby rocks and soil. Water softeners are called upon to eradicate hardness to mitigate the lethal effects of hard water on human skin, household appliances, and plumbing fixtures. Using the ion exchange process, they essentially displace the hard ions, consequently substituting them with sodium or potassium ions, which are less objectionable. This softens the river water, ultimately minimizing detergent usage, elevating the water’s taste, and protecting plumbing fixtures.
● Carbon Filters
Agricultural run-off water as well as residential and industrial effluent contains high levels of pesticides, herbicides, VOCs, and other chemicals, which often find their way into river water due to improper disposal. Using activated carbon filters, all these contaminants are effectively ejected from the river water through adsorption. This also helps improve the water’s clarity, taste, and odor. They are highly favored by homeowners owing to their reasonable pricing and easy installation process.
● Multimedia Filters
Sand, grit, debris, and a whole range of other suspended solids are some of the most popular impurities present in river water. Although they can be eliminated via numerous filtration methods, multimedia filters are the most common and effective tools for suspended solids removal. Characteristically, they blend different filter media, including sand, gravel, and anthracite to elevate their filtration range and levels. They are suitable for pre-treatment before other filtration systems like RO or UV sterilizers.
Why Homes Should Purify River Water Before Use?
● Elimination of Pathogens
The removal of harmful pathogens from river water is crucial, as it may contain various disease-causing bacteria, viruses, and parasites. Water purification methods can effectively eliminate these harmful pathogens, thus preventing the spread of waterborne diseases.
● Removal of Chemicals
Chemical contaminants such as pesticides, fertilizers, and industrial waste can also be found in river water. These contaminants can pose serious threats to human health, but water purification can effectively remove them.
● Better Taste and Odor
Additionally, river water may have an unpleasant taste and odor due to the presence of algae, sediment, and organic matter. Water purification can help to improve the taste and odor of the water, making it more palatable for drinking and other uses.
● Protecting Appliances
Purifying river water can also help protect appliances such as washing machines, dishwashers, and coffee makers, as water that is not purified can contain minerals and other substances that can build up and cause damage to these appliances.
● Environmental Conservation
Finally, using purified river water instead of bottled water can help to conserve resources and reduce the environmental impact associated with the production and transportation of bottled water. Individuals can contribute to environmental conservation and reduce their carbon footprint by purifying river water.
