What is Ceramic Water Purifier (CWP)?
A ceramic water filter is a very simple unit. It looks like bucket-shaped clay vessel. Sawdust, a mix of local terra-cotta clay and other combustibles like rice husk are the elements of the filter. The unit is manufactured by applying a press.
The normal press uses a hand-operated hydraulic truck jack and 2 piece aluminum molds. The filter is excited with 860 degrees C. Examiners test the filter well to know the speed of filtration.
After that, they are covered with the colloidal silver. The mixture of the bactericidal property and fine pore makes an effectual filter.
The treated filter and the fired have set in a 5 gallon ceramic or a plastic container with faucet and a lid. Water goes through the soil filter constituent to rate of 1.5 to 2.5 liters/ hour.
Why ceramic water filters are SAFE
People of the developed countries store water from outward sources in their home. Here contamination is very weak.
The water of these sources is clean near the source. If clean water is taken back from a village well to a clean bucket, it may be contaminated. As there is no lid on water, it can pollute. Tap is another convenient source of water.
It never contaminates as it is not treated for broken pipes or poor infrastructure on the way to tap. In many places, it is not possible to manage the cleanest source of water for a long time for different causes.
If a man uses household water treatment and safe storage (HWTS), he can remove these problems. He can provide an effective and simple solution for the cities, nations, and villages. It is useful where there is no reliable drinking water distribution system.
HWTS promotes to use it directly in your home to upgrade water standard. Academic and government researchers make a test. They get that HWTS is the most effective system to remove diarrheal diseases.
A lot of HWTs products are used today. Among them chlorination, flocculation/disinfection, ceramic filtration, biosand filtration, solar disinfection are famous. These products help people to reduce diarrhea and pathogenic organisms.
Therefore HWTS products are very effective and would be very appealing to the people. People use the system all time without thinking efficiency, sophistication, and affordability.
Ceramic water filters (CWF) have much popularity rate to the many communities. The filters are HWTS options. Customers like to use it for their good health. They use it for clear, cool and great tasting water.
Customers feel these filters aren’t usually found for other HWTS alternatives. CDC and academic researchers admit that CWFs are efficient to reduce diarrheal infection. It removes diarrheal from 29% – 79% and potentially pathogenic germs and protozoa up 99.99%.
Benefits of Ceramic Water Purifiers
We know that our bodies have at best 75% of water. An adult should drink at least eight glasses of clean water every day to satisfy thirst. Water is a must for our body. It aids our body in nutrients assimilation and subtraction of waste.
The tap water is contaminated with different pollutants like hair, dirt, fumes. Cream, algae, agricultural pesticides, hydrocarbons, and industrial waste can contaminate water.
Authorities added many things like aluminum, chlorine, and copper in water. These elements create fouls tasting cocktail and a tainted smelling.
If you drink water from the tank a and the value of the water can be worse. Frogs, insects, birds, reptiles, rodents, etc. may enter into rainwater reservoirs.
Their dropping may pollute water. Twigs, leaves, dust, corroded metals, cane ash, smoke, woodfire elements and residues can spoil the water.
If you supply water from springs, dams, underground bores and streams, you will think about faucal pollutants. The demand for efficient purification of drinking water has not been larger.
Anything except oxygen and hydrogen is a pollutant. Many of these contaminants are positively connected to terminal illnesses and acute chronic.
The Southern Cross Pottery Water Purifying system and the carbon stimulate ceramic filters are very efficient.
These systems can remove chlorine, bacteria, pesticides, suspended solids, amoeba, cysts and heavy metals from water. The laboratory tests show that the Royal Doulton Super Sterasyl filters are helpful.
- Cyst Reduction ( Cryptosporidium & Giardia) 99.99%
- Chlorine Reduction 95%
- Bacteria Reduction (E.coli, Cholera, Salmonella) 99.99%
- NSF Turbidity Reduction std.53 99.69%
- Algae, Rust, Sediment Reduction 99.99%
Development and expansion
Henry Doulton was the pioneer who made the modern type of ceramic candle hygienic filter in 1827.
Queen Victoria commissioned him in 1835 to make a device for her use. In 1846, Doulton ceramics was popular for inventing an efficient water treatment system. In 1887, Doulton became the knight of his work with water filters.
Louis Pasteur used the filters for his research regarding bacteria. Doulton’s organization of water filter remains alive through several times the names had been changed. Doulton is at present a recorded brand of Fairey Ceramics.
Universities of Colorado, MIT, University of Wisconsin-Milwaukee, Universities of Tulane, the Ohio State University, Earth University, North Carolina in the US, West Virginia, University of Delft, USAID, Strathclyde in Europe, UNICEF, Rafael Landivar University in Guatemala, Zamorano University in Honduras use a ceramic filter.
Some other organizations like Red Cross, Countries in Asia like Nepal, United Nations, Engineers Without Borders, Institute of Hydraulic resources, Countries in Africa like Nigeria, Vietnam, Burkina Faso, Ghana, Kenya, etc. use it.
Some countries like Sri Lanka, Bangladesh, Cambodia, India, etc. are holding up the extension of the application of ceramic filters for drinking water.
Mr. Fernando Mazariegos of Guatemala was responsible for upgrading Ceramic Pot Filter technology in 1981. He was the director of the Central American Research Institue in Guatemala City during this time.
Now he is the director of research and expansion at Ecofiltro in Antigua, Guatemala. Ron Rivera got an education under Mr. Mazariegos of Guatemala. He was the inventor of ceramic frustum formed filter all through international borders.
He helped the developed nations by giving inexpensive high transferable water. Ron Rivera worked with Potters to maintain their business in developing nations.
Maintenance of Ceramic Water Purifiers
The flow rate may extend by normally brushing its exterior surface. You can use a plastic brush, a stiff toothbrush and a soft searching pad beneath running water to do it.
As the upper portion of the contaminants and ceramics are visible, a new level becomes vivid. Do this process more than 50 times or up to the diameter reaches 1.75/44 in. /mm.
One has to change the cartridge every 12 to 24 months as the carbon media may become exhausted very quickly.
- If one doesn’t use a filter for 2 days or longer, he should wash the first two qts. /liters. And then allow fresh water supply through the filter.
- Remove cartridge with caution from the component and grip it like a fragile ceramic.
- Use a soft scouring pad or a soft toothbrush; scrub the filter beneath running water or into a bowl of water. All-time brush away from the threaded mount, don’t contaminate the mount. Advice, never use detergents, soap and steel wool.
- Before reinstalling it, keep the sealing washer in the right position.
- At first, the filter demands air dried for up to 24 hours.
- If you drop the cartridge accidentally, it may not break. Do the following tests to ensure its integrity.
- Plunge it in a water container at the time of holding a finger on the outlet to preserve the air within.
- The trapped air may exit through it when there is a crack. You may notice bubbles representing replacement.
Suggestions: At the time of cleaning, use rubber gloves. Envelop the threaded mount with a rubber band, plastic, and the cartridge O ring.
