5 types of water filtration systems

Over time, the water filtration system has undergone several technological advancements to provide water access to billions of people worldwide. There are not just one but several ways pollutants can be removed from water. Depending on the location, area, and need, an appropriate type of filtration system can be used for water purification. Below are some of the different types of popular water filtration or treatment systems that are helpful.

Mechanical filters
This is one of the most standard and most common methods of filtering water. A physical barrier is used in the filtration system, which helps remove the dirt, particles, and chemicals from the liquid. The water usually travels through this mechanical filter, made of synthetic foam and nylon floss that helps clean out the water’s physical impurities. For this reason, this is often a prevalent method for the pre-filtration process.

Ion exchange filters
This is usually one of the most effective ways of filtering out the impurities from the water. In this method, the filtration system works by splitting the atoms of the contaminated particles, like chemicals and dirt, into ions, which is done using limescale. This ion water softener is also the best way to soften hard water. This is usually used in commercial places to help store water safely at a low temperature. There are also other unique ways of using ion exchange resin in the form of tiny beads that help replace contaminants with sodium ions that keep the water clean.

Activated carbon filters
These are also known as absorption filters, commonly installed in homes. This type of filtration system contains a large internal surface with nooks and hooks responsible for trapping water pollutants. This type of filtration system is also a bit pricier as it helps reduce the odor and bad taste of the water that comes from contaminants. Activated carbon is made up of granules of charcoal that are highly absorbent, making it an effective way to filter out liquids.

Reverse osmosis filters
This type of filtration uses two types of technologies – the mechanical filter and the activated charcoal filter, which helps give water with much fewer contaminants. In this method, the polluted water is forcefully passed through a membrane using a specific pressure. This pressure allows for the water to pass through. However, the pollutants or impure particles are left behind. There could be dissolved particles like magnesium, calcium, and more, but with the correct pressure, the water passes through, leaving these particles behind. RO or Reverse Osmosis is usually used in kitchen spaces.

Ultraviolet filters
In this method of filtration, the water is diverted towards ultraviolet light. This light then helps kill pollutants like viruses, parasites, and bacteria. One of the perks of this filtration system is that it runs on battery and is lightweight so that it can be carried around easily. However, this type of filtration will not be able to remove solid materials from the water, just the chemicals. The ultraviolet filters attract microbial bacteria cells to kill them and purify the water. One can use this filter combined with other filter types to eliminate contaminants such as chlorine, lead, and pesticides to deliver clean, soft, and healthy drinking water.

Learn about these 3 types of hearing loss

Hearing loss, deafness, or impairment is the partial or total inability to hear sounds. People with low to moderate hearing impairment face challenges in understanding what the other person is saying in a noisy environment. Whereas, people with severe deafness cannot hear anything, and rely completely on lip-reading and sign language skills. There are three main types of hearing loss: sensorineural, conductive, and a combination of both. Let’s understand these types in detail and learn about the causes, symptoms, and treatments of each type. Sensorineural hearing loss It’s the most common type of hearing loss. Sensorineural is permanent hearing loss often caused by damage to the tiny hair cells that line the inner ear or the auditory nerve. The damage stops or weakens the transfers of nerve signals to the brain. These signals are essentially the intensity and clarity of sounds. Causes: Aging and exposure to loud noises for a long period of time are the most common cause of the damage. Certain medications and illnesses can also increase risks. It can even be genetic, and pass on to the child in the mother’s womb. Treatment: There is no medical or surgical treatment available to repair the tiny hair cells once they’re damaged.
Simple lifestyle changes that reduce the risk of heart diseases

Simple lifestyle changes that reduce the risk of heart diseases

The heart is the most crucial organ in the body and as the system will cease to function if the heart stops or loses momentum pumping fresh oxygenated blood. This is why it is vital to not neglect your heart health at all and responsibly maintain a healthy, stress-free, and more importantly, a happy lifestyle. Here are a few simple lifestyle changes that will help support a healthy heart function. Switch to a healthy diet Avoid eating foods that are rich in trans and saturated fats. Most foods you find on the shelves of the supermarket contain large quantities of one or the other. Instead, switch to low-fat high fiber alternatives to help manage cholesterol. Maintaining a healthy cholesterol level in the body automatically reduces the risk of heart diseases. The simple reason for this is that fats that normally block major arteries and blood vessels are eliminated from these foods choices. It is also advisable to limit the salt (sodium) intake to control blood pressure and sugar to reduce the risk of diabetes simultaneously. Change certain lifestyle habits Reduce the number of alcoholic or carbonated drinks you have regularly. For men, it is advisable to have not more than two drinks and day and women must have only one.
How to distinguish between heartburn and GERD

How to distinguish between heartburn and GERD

Heartburn is an unpleasant, burning sensation in the chest that is more common than a lot of individuals realize. Pregnant women, older men, and even young adults experience it frequently. Despite it being such a prevalent experience, not many know that heartburn has actually nothing to do with the heart and everything to do with the stomach and the esophagus. Unsurprisingly enough, heartburn is also used interchangeably with GERD. But, before we get to deciphering heartburn and GERD, let’s understand what acid reflux is. What is acid reflux or GER? Acid reflux occurs when the lower esophageal sphincter or LES becomes weak, allowing the contents of the stomach to travel in the wrong direction, back up the esophagus. Acid reflux is also called GER or gastroesophageal reflux as it involves the stomach and esophagus. This condition can usually be resolved with over-the-counter medication. What is heartburn? Heartburn is a burning or painful sensation that is experienced in the chest. Since the lining of the esophagus is not as strong as the lining of the stomach, the acid from the stomach can cause a burning sensation in the chest. This pain or burning sensation that is heartburn can often be misconstrued for a heart attack.

5 common joint conditions and how to treat them

A joint or articulation is made from two bones that aid the body in movement. There are many forms of joint conditions, which, in many cases, arise from the wear and tear of bones. Arthritis is one of the major and most common health conditions in the country, and its intensity increases with age. Here are some common types of joint conditions that you need to know: Osteoarthritis With almost 10 percent of men and 13 percent of women aged over 60 suffering from osteoarthritis, it is one of the most prevalent joint conditions in the country. Osteoarthritis occurs due to the wear and tear of the cartilages that protect the ends of bones. It commonly affects joints of the spine, hands, hips, and knees. If left untreated, this wear and tear of the cartilage soon leads to bone degeneration, thereby affecting flexibility and range of movement. Treatment for osteoarthritis depends on its severity and the patient’s age. Mild symptoms can be treated through medications, physiotherapy, and changes in lifestyle, whereas moderate to severe cases may require surgical intervention. Spondyloarthritis Spondyloarthritis, also referred to as spondyloarthropathy, is a type of rheumatic disease that causes inflammation in various joints. There are two types of spondyloarthritis—axial spondyloarthritis, which causes inflammation of the joints in the chest, spine, and hip bone, and peripheral spondyloarthritis, which causes inflammation in the fingers, knees, and toes.
