Water treatment and filtration system
Water treatment and filtration system are of nice concern once it involves portable water consumption. Environmental pollution is world challenge with each country implementing various ways meshed towards re-sustaining its environment. Clean, safe water is vital for everyday life.
Drinking water sources will become contaminated, causing sickness and disease from waterborne germs, such as Cryptosporidium, E. coli, Hepatitis A, Giardia intestinalis, and other pathogens. " water treatment and filtration system"
Drinking water sources are subject to contamination and require appropriate treatment to remove disease-causing agents. Public drinking water systems use various methods of water treatment to provide safe drinking water for their communities.
Drinking water sources are subject to contamination and need applicable treatment to get rid of disease-causing agents. Public water systems use varied strategies of water treatment to supply safe water for his or her communities.
Water could also be treated otherwise in several communities counting on the standard of the water that enters the treatment plant. Typically, surface water requires more treatment and filtration than groundwater because lakes, rivers, and streams contain more sediment and pollutants and are more likely to be contaminated than groundwater.

Today, the foremost common steps in water treatment utilized by community water systems (mainly surface water treatment) include:
Coagulation / Flocculation
These are typically the primary steps in water treatment. Chemicals (liquid aluminum sulfate (alum) and/or polymer) with a positive charge are additional and mixed with water. The charge of these chemicals neutralizes the negative charge of dirt by causing the small particles of dirt in the water to stay together or coagulate. When this happens, the particles bind with the chemicals and form larger particles, called floc. which area unit easier to get rid of by subsiding or filtration.
In the course of sedimentation, as the water and the floc particles progress through the treatment process, Heavy floc particles settle to the bottom of the water supply, due to its weight. Floc that collects on the bottom of the basin is termed sludge and the floc is removed by filtration solely.
During Filtration Water flows through a filter designed to get rid of particles within the water. The filters are made from layers of sand, Charcoal, and gravel, and in some cases, crushed anthracite. Filtration collects the suspended impurities in water and enhances the effectiveness of medical aid
Filtration helps in the removal of dissolved particles, such as dust, parasites, bacteria, viruses, and chemicals.
After water filtration, the water is disinfected before it enters the distribution system using disinfectants like chlorine and chloramines to kill any remaining parasites, bacteria, and viruses, and to protect the water from germs once it's piped to homes and businesses.
Chlorine is used because it is a very effective disinfectant, and residual concentrations can be maintained to guard against possible biological contamination in the water distribution system "water treatment and filtration system"
Solids that are collected and settled out of the water by deposit and filtration are removed to drying lagoons. "water treatment and filtration system"
Water fluoridization is the treatment of community water supplies for the aim of adjusting the concentration of the free fluoride particle to the optimum level adequate to cut back tooth decay. Community water fluoridization prevents dental caries safely and effectively
Household Water Treatment
In our homes water is treated in numerous forms before consumption; below are reasons for home water treatment :
- To remove specific contaminants
- To take additional precautions as a result of a social unit member features a compromised system
- To improve the taste of drinking water
The most common types of household water treatment systems:
A filter may be a device that removes impurities from water by means that of a physical barrier, chemical, and/or biological process.
A softener may be a device that reduces the hardness of the water. A softener usually uses Na or K ions to exchange Ca and Mg ions, the ions that create “hardness.”
Distillation is a method within which impure water is cooked and therefore the steam is collected and condensed in a very separate container, leaving many of the solid contaminants behind. "water treatment and filtration system"
Disinfection is a physical or chemical change within which infective microorganisms are deactivated or killed. Examples of chemical disinfectants are Cl, chlorine dioxide, and ozone. Examples of physical disinfectants include ultraviolet illumination, electronic radiation, and heat.
Community and house hold water treatment is of great importance because it helps alleviate healthy living. A frequent and habitual practice of water treatment is needed. "water treatment and filtration system"
