4 Effective Feed Water Treatment Methods

Water is a precious and essential resource for human life. However, not all water sources meet the standards of quality and safety for direct use. Therefore, the treatment of feed water becomes necessary to remove impurities, pollutants and harmful microorganisms, ensuring water sources meet the standards of quality and safety for domestic, industrial or agricultural purposes.

4 common and effective feed water treatment methods:

Physical handling

  • Sedimentation : The sedimentation process helps remove suspended solids and sludge residue in the water through the difference in density. Water is introduced into the sedimentation tank and the solids will settle to the bottom, while the clear water will be collected above.
  • Filtration : Filtration methods use filter materials such as sand, rocks, activated carbon or membranes to remove solid particles, sludge residue and some organic matter from water. Common types of filtration include rapid filtration, slow filtration, pressure filtration and membrane filtration.
  • Ultrafiltration (UF) and UV electromagnetic energy : UF is a filtration method that uses a small pore-sized membrane to remove solid particles, microorganisms and some organic matter. UV electromagnetic energy is used to kill bacteria, viruses and fungi in water.

Chemical treatment

  • Disinfection : Use disinfectants such as chlorine, ozone or chlorine dioxide to kill pathogenic microorganisms and purify water.
  • pH stability : Adjust the pH of the water by adding acid or alkali to reach a pH value suitable for its intended use.
  • Detoxification : Removes toxic substances such as heavy metals, phenols, petroleum, and other organic compounds using methods of adsorption, ion exchange, or oxidation.
  • Water softening : Removes calcium and magnesium ions that cause hard water conditions by using ion exchangers or water softening chemicals.

Biological treatment

  • Aerobic treatment : Uses aerobic microorganisms to break down organic matter in water, converting them into carbon dioxide and water.
  • Anaerobic treatment : The process of treating water with anaerobic microorganisms in an environment with no or limited oxygen to decompose organic matter.
  • Activated sludge : Using a mixture of aerobic and anaerobic microorganisms to treat domestic and industrial wastewater, removing organic matter and nutrients.

Special handling

  • Salt separation : Removing salts and minerals from water using methods such as reverse osmosis, ion separation or electrolysis.
  • Radioactive removal : Removing radioactive substances from water using methods such as ion exchange, adsorption or membrane filtration.
  • Well water treatment : Remove impurities and toxic substances such as iron, manganese, arsenic, fluoride and nitrate in well water by appropriate chemical and physical methods.
The choice of the appropriate water treatment method depends on many factors such as the quality of the input water, the purpose of use, scale and investment costs. In many cases, water treatment methods are combined to achieve the highest efficiency. In addition, the maintenance and proper operation of the water treatment system also plays an important role to ensure the quality of the output water is up to standard.
In addition, using water effectively and protecting water from pollution are important measures that contribute to reducing the need for water treatment and protecting the environment. Every individual and organization is responsible for using water responsibly and taking measures to prevent water pollution.
