Water Purification

Water purification is an essential process that has become increasingly important in recent years due to the growing population and environmental pollution. It involves removing impurities, contaminants, and pollutants from water to make it safe for human consumption.

Water Purification Info & Methods

Types of Contaminants

Water is an essential resource for all living organisms, and it is crucial that it is safe for consumption. However, contaminants in drinking water can pose a serious threat to human health. Contaminants in drinking water can come from natural sources, such as minerals and organic matter, or from human activities like industrial waste disposal and agricultural runoff. Some of the most common contaminants found in drinking water include bacteria, viruses, parasites, heavy metals like lead and mercury, pesticides, and pharmaceuticals.

Bacteria and viruses are some of the most dangerous contaminants found in drinking water as they can cause illnesses such as diarrhea, cholera, typhoid fever among others. Parasites like Giardia are also a significant public health concern that can cause severe gastrointestinal symptoms. Heavy metals like lead and mercury are toxic to humans even at low concentrations and can cause developmental delays in children if ingested over time.

Pesticides used for farming purposes have been found to be hazardous when consumed through drinking water. They are known to affect the nervous system causing headaches or dizziness; long-term exposure may lead to cancer or reproductive problems.

Pharmaceuticals have been detected in tap water due to improper disposal of drugs by humans or through excretion. These compounds have been linked with liver damage when consumed over time.

To ensure that drinking water is safe for consumption, various methods of purification must be employed at different stages of the treatment process. These methods include coagulation/flocculation (removal of suspended solids), sedimentation (settling out suspended particles), filtration (removal of remaining particles), chlorination/UV treatment (killing bacteria/viruses) among others.

Methods of Water Treatment

Water treatment is the process of removing impurities and contaminants from water to make it safe for consumption. There are several methods of water treatment that can be used depending on the type and level of contamination present in the water. One common method is sedimentation, which involves allowing the water to stand still so that any large particles or organic matter can settle at the bottom. The clear water is then decanted into another container for further treatment.

Another popular method of water treatment is filtration, which involves passing the water through a series of filters to remove impurities such as sand, gravel, and activated carbon. Filtration can be done using different types of filters such as slow sand filters, rapid gravity filters, and membrane filters. Slow sand filters are effective in removing bacteria and viruses while rapid gravity filters are better suited for removing larger particles.

Disinfection is another critical step in water treatment to kill any remaining microorganisms that may cause disease. Chlorination is one common method used for disinfection where chlorine gas or hypochlorite solutions are added to the water to kill bacteria and viruses. Another method used for disinfection is ultraviolet (UV) radiation where UV rays are passed through the water to destroy any remaining microorganisms.

Reverse osmosis (RO) is a more advanced technique used in treating brackish or seawater by forcing it through a semi-permeable membrane that removes dissolved salts and other impurities from the water. RO systems require high pressure pumps to force water through membranes with microscopic pores that trap salt ions while allowing pure freshwater molecules to pass through.

Coagulation Flocculation

Coagulation is a vital process in water treatment, and it involves the addition of chemicals to raw water to destabilize and clump together suspended particles. The primary objective of coagulation is to form large flocs that can be easily removed through sedimentation, flotation, or filtration processes. Coagulation plays an essential role in ensuring that drinking water meets the stringent quality standards set by regulatory agencies. In this paragraph, we will discuss the importance of coagulation in water treatment.

Firstly, coagulation helps to remove suspended solids from raw water. Suspended solids such as clay, silt, and organic matter can make water turbid and unappealing for consumption. Turbidity is a measure of the cloudiness or haziness of water caused by suspended particles. High turbidity levels in drinking water can lead to health concerns such as gastrointestinal illnesses due to the presence of harmful microorganisms such as bacteria and viruses. Coagulants like alum or ferric chloride are added to raw water during coagulation; they neutralize the charges on suspended particles which then clump together into larger flocs that settle quickly under gravity.

Secondly, coagulation helps remove dissolved substances from raw water. Some dissolved substances like color compounds, heavy metals (lead and mercury), and natural organic matter may not be removed through conventional filtration processes alone but can be removed through chemical precipitation during coagulation/flocculation processes. Coagulants react with these dissolved substances resulting in their precipitation into larger particles which can then be filtered out.

Thirdly, coagulation plays an important role in pre-treatment for other advanced wastewater treatments such as reverse osmosis (RO) or desalination systems because it removes colloidal-sized particles that would otherwise foul RO membranes leading to increased maintenance costs or even membrane failure.

Lastly, effective coagulant dosing ensures efficient use of expensive downstream treatment processes like activated carbon adsorption or ion exchange resin beds used for removing trace contaminants like pesticides or pharmaceuticals from treated wastewater before discharge into receiving watersheds.

Coagulation is a critical process used in drinking-water treatment because it helps remove both suspended and dissolved impurities from raw source waters.

Water Chlorination

Water chlorination is the process of adding chlorine to water in order to kill bacteria and viruses that can cause diseases. It has been used for over a century as an effective method of disinfecting water supplies. There are several advantages to using water chlorination as a method of water treatment.

Firstly, chlorination is a highly effective method of killing harmful microorganisms in water. Chlorine is a powerful disinfectant that can kill a wide range of bacteria, viruses, and other pathogens that can cause illnesses such as cholera, typhoid fever, and dysentery. This makes it an essential tool in preventing the spread of waterborne diseases.

Secondly, chlorination is a relatively inexpensive method of treating water. The cost of adding chlorine to water is low compared to other methods such as filtration or UV treatment. This makes it an attractive option for many communities with limited resources for maintaining their drinking water supplies.

Thirdly, chlorination is easy to implement and maintain. Unlike other methods that require complex equipment or specialized knowledge, adding chlorine to water only requires basic equipment and training.

Finally, chlorination provides residual protection against recontamination during distribution and storage. Chlorine remains active in the treated water long after it has left the treatment plant, providing ongoing protection against any new sources of contamination that may be introduced along the way.

There are several advantages to using chlorination as a method of treating drinking water. Its effectiveness at killing harmful microorganisms combined with its low cost and ease of implementation make it an attractive option for many communities around the world. Furthermore, its ability to provide residual protection against recontamination makes it an essential tool in ensuring safe drinking water supplies for all people regardless of where they live or what their economic status may be.

Risks And Side Effects Of Chlorination:

While chlorination is a widely accepted method of disinfecting drinking water, it is not without its risks and side effects. One of the main concerns with chlorination is the formation of disinfection byproducts (DBPs). DBPs are formed when chlorine reacts with organic matter in the water, such as decaying leaves or algae. The most common DBPs are trihalomethanes (THMs) and haloacetic acids (HAAs). These compounds have been linked to an increased risk of cancer, reproductive problems, and other health issues.

Another potential risk associated with chlorination is the presence of residual chlorine in the water. While low levels of residual chlorine are necessary for effective disinfection, excessive levels can cause skin irritation and other health problems. In addition, some people may be particularly sensitive to chlorine and experience allergic reactions or respiratory problems when exposed to even small amounts.

Chlorine also has a negative impact on the taste and odor of drinking water. Many people report that chlorinated water has a chemical-like taste that makes it less palatable. Chlorine can also react with other substances in the water to create unpleasant odors.

Overall, while chlorination remains an important method for ensuring safe drinking water, it is important to be aware of its potential risks and side effects. Efforts should be made to minimize these risks through proper treatment techniques.


Chlorine levels up to 4 milligrams per liter (mg/L or 4 parts per million (ppm)) are considered safe in drinking water. At this level, harmful health effects are unlikely to occur.

Reverse Osmosis

Reverse osmosis is a process of removing impurities from water by applying pressure to force water molecules through a semipermeable membrane. The reverse osmosis process uses a high-pressure pump to push the water through the membrane, which removes impurities such as minerals, chemicals, and other contaminants. The principles of reverse osmosis are based on the concept of selective permeability, where only certain types of molecules can pass through the membrane.

The reverse osmosis process involves several key steps. First, raw water is fed into a pre-treatment system that removes larger particles and sediment from the water. This step helps protect the membrane from damage and ensures that it operates efficiently. Once pretreated, the water is passed through a high-pressure pump that forces it through the semipermeable membrane.

The semipermeable membrane used in reverse osmosis contains tiny pores that allow only pure water molecules to pass through while blocking larger molecules such as salts and other impurities. This selective permeability means that only pure water passes through while all other contaminants are left behind. The purified water is then collected on one side of the membrane while concentrated brine or reject stream containing all impurities is collected on another side.

There are two primary types of membranes used in reverse osmosis: thin-film composite (TFC) and cellulose acetate (CA). TFC membranes are made up of multiple thin layers of polymer materials with an active layer consisting primarily of polyamide polymers. These membranes offer high rejection rates for most impurities but may be more susceptible to fouling due to their thin construction. On the other hand, CA membranes consist mainly of cellulose acetate polymers and provide excellent rejection rates for dissolved solids but may be less effective against organic compounds.

The efficiency and effectiveness of reverse osmosis depend on several factors such as feedwater quality, operating pressure, temperature, flow rate, and feedwater pH. For instance, high feedwater quality with low levels of dissolved solids will result in higher permeate production rates compared to poor-quality feedwater with high levels of dissolved solids.

In addition to these factors affecting efficiency and effectiveness during operation there are also some design considerations for RO systems such as module configuration (spiral-wound or hollow fiber), number or stages required depending upon desired product quality etc..

Overall Reverse Osmosis has become an important part in providing clean drinking water. With its ability to remove up 99%+ percent dissolved salts & ions , RO has proven itself as reliable method for desalination purposes too.
