Waterborne Water Purifier
Waterborne diseases caused by contaminated drinking water have always posed significant health risks. From typhoid and cholera to hepatitis A and E. coli infections, there are numerous harmful microbes that can get into drinking water sources and spread illness in communities. In developing nations where access to clean water is limited, waterborne disease outbreaks are still common. Even in developed countries, drinking untreated water from streams and lakes carries risks. Having a reliable water purification system at home helps eliminate such risks.
Types of Water Purifier
Water sources can become contaminated due to various reasons. Surface water bodies like lakes and rivers are prone to pollution from industrial effluents, agricultural run-off and human/animal waste carrying pathogens. Groundwater sources below the earth's surface may contain naturally occurring toxins like arsenic. In some areas, lead from old pipes can leach into the water supply as well. Other common contaminants include chemicals, toxins, suspended solids, heavy metals and excess minerals. All of these impurities must be removed for water to be considered potable and safe for drinking.
Mechanisms of Water Filtration
Most household Water Purifier utilize multiple filtration technologies working in tandem to purify water efficiently:
Sediment filtration - This is the first stage where suspended particles like rust, sand and sediments are trapped in the filter media to clarify the water. Common filter materials used are carbon blocks, ceramics and porous resins.
Carbon filtration - Activated carbon granules in the filter remove a wide range of dissolved contaminants like pesticides, chemicals, VOCs, herbicides and residual chlorine through adsorption. It also improves taste and odor.
Ultrafiltration - This membrane-based process removes up to 99.99% bacteria and protozoan cysts from water by using a semi-permeable polymer membrane with pore size small enough to trap microscopic pathogens.
UV purification – Water Purifier Challenges are Exposing water to UV light of a specific wavelength disables DNA/RNA of microorganisms like bacteria, viruses and parasites, thereby inactivating them. This gives an added layer of purification.
Mineral filters- Adding essential minerals like calcium and magnesium helps balance the water chemistry and improves taste. Some purifiers also remove excess heavy metals.
Reverse osmosis - This sophisticated desalination process forces water molecules through a semi-permeable membrane, removing ionized salts and other total dissolved solids to make water safe for drinking.
Types of Water filterings on the Market
Pitcher/jug filters: These manual water filters can be used for purifying water stored in pitchers and jugs at home. They offer 1-2 stage purification through carbon filtration and come at budget-friendly price points.
Under-sink/faucet mount systems: Popular whole-house purifiers that connect directly to the kitchen faucet or under the sink. Most feature 3-4 stage filtration and convenient design ensuring purity of all water used for drinking and cooking.
Counter-top purifiers: Freestanding compact units with large containers for purified water storage. Typically utilize ultraviolet disinfection along with 5-7 stage filtration to render municipal water supply microbial-free.
Reverse osmosis systems: Considered the most effective home purification systems, RO units completely demineralize water, reducing total dissolved solids to near-zero levels. They require plumbing installation under sinks.
Gravity-fed/canisters: These portable point-of-use filters have a gravity-fed design. After pouring untreated water into the upper chamber, it undergoes carbon purification and collects at the bottom as clean water. They find application during outdoor activities or camping trips.
Whole house systems: Large centralized filtration units tied to the main water line deliver purified water throughout homes. Preferred for applications like shower filtration, larger families, and well/private supplies requiring complete treatment.
Key Benefits of Having a Home Water filtering
Reduces health risks - Purified water safeguards you and family from waterborne diseases caused by microscopic parasites, bacteria and viruses commonly found in untreated water sources.
Improves taste - Filtered water is crisper and tastes better than chlorinated municipal supply. Removes odors, chemicals, and minerals that can affect taste and smell.
Extends appliance lifespan - By removing sediments, chemicals and excess minerals, purified water protects plumbing fixtures, water heaters, dishwashers and washing machines from scale build-up inside. Lengthens equipment lifespan significantly.
Lowers maintenance costs - By preventing mineral deposits, water softeners are less burdened, thereby reducing salt and resin replacement costs. Other peripherals work more efficiently too.
Saves money - Compared to buying bottled water regularly, a home water filtering pays for itself within a couple of years through significantly lower out-of-pocket costs. Also boosts property values.
Eco-friendly option - Reduces plastic waste from discarded water bottles used daily. A sustainable long-term solution for access to clean drinking water without polluting the planet.
Peace of mind - Provides reassurance of having healthy, safe and pure water available right from the kitchen faucet at all times - a basic amenity taken for granted by many. Especially crucial during crisis situations.
In Summary, considering the vital role of water in our daily lives and the ubiquity of sources carrying health risks, a water filtering is certainly a necessity, not a luxury, for any modern household. Besides health and safety factors, there are multiple other benefits that easily
