Clean and safe water: Learn about the main purification systems available

Main water purification systems: Water purification systems are essential to ensure access to clean and safe water for human consumption. Water can be contaminated by a variety of substances, including bacteria, viruses, parasites, chemicals, and heavy metals. Drinking contaminated water can lead to serious illnesses such as cholera, dysentery, hepatitis A, and typhoid fever.

Throughout history, different methods have been used to purify water, including boiling, filtration, the use of chlorine and other chemicals, and reverse osmosis. However, modern water purification systems are much more advanced than these ancient methods.

The first modern were developed in the late 19th and early 20th centuries. One of the pioneers in this area was a the British chemist and bacteriologist Thomas Fuller. Who developed the first large-scale water purification system in 1897. This system used a combination of coagulation, filtration, and chlorination to remove bacteria and other contaminants from water.

Since then, water purification systems have been improved and perfected, becoming increasingly efficient and sophisticated. Modern water purification systems are capable of removing a wide variety of contaminants. One of the biggest advantages of water purification systems is the ability to provide clean, safe water for human consumption in places where water is not naturally clean or where water sources are contaminated.

This includes rural areas, where water can be contaminated by fertilizers, pesticides, and other chemicals. Water purification systems are used around the world by a wide variety of people and organizations. Including governments, businesses, hospitals, schools, and private homes. They are especially important in areas where access to clean, safe water is limited or non-existent, such as in developing countries or areas affected by natural disasters.

Main water purification systems

  • Reverse Osmosis: In short, this is a water purification method that removes contaminants through a semipermeable membrane. Water is forced through the membrane under pressure, and contaminants are trapped, leaving the water clean;
  • Membrane filtration: This method uses a membrane to remove bacteria, viruses, and other contaminants from the water. Membrane filtration can be done using different types of membranes, including microfiltration, ultrafiltration, and nanofiltration membranes;
  • Activated carbon filtration: This method uses activated carbon to remove chemicals, odors, and tastes from the water. Activated charcoal is treated with oxygen to open its pores, making it able to absorb organic compounds from water;
  • Ultraviolet light disinfection: This method uses ultraviolet light to kill bacteria, viruses, and other microorganisms in the water. The water is exposed to an ultraviolet light source. Which damages the DNA of microorganisms and makes them unable to reproduce;
  • Chlorination Disinfection: In short, this is a common method of water disinfection that involves adding chlorine to the water to kill bacteria and other microorganisms. Chlorine can also help remove odors and flavors from water;
  • Distillation: This method involves evaporating water to remove contaminants and then condensing the steam to produce clean water. Distillation is an effective method of purifying water, but it can be expensive and energy-consuming;
  • Reverse electrodialysis: This method involves the separation of ions from water through electrically charged membranes. The process removes ionic contaminants such as salts, heavy metals, and nitrates from the water;


In short, water purification is a fundamental process to guarantee the safety and quality of the water we consume. There are several options available, each with its advantages and disadvantages. Choosing the right water purification system depends on the contaminants in the water, the purpose of the water, and the needs of the user.

The use of water purification systems is not just limited to individuals who do not have access to safe drinking water. Large industries, hospitals, laboratories, and other organizations that require high-purity water also use water purification systems to meet their needs. In short, water purification systems are an important solution to ensure that the water we drink is free of contaminants that are harmful to human health and the environment.
