Main points and terms you need to know about in water treatment process.
Water treatment plants may use physical, chemical, and biological processes to purify water. The specific processes used will depend on the quality of the source water and the desired end-use of the water.
Here is a list of terms commonly used in water treatment processes:
- Activated carbon: A highly porous form of carbon used to remove water impurities by adsorption.
- Coagulation: The process of adding chemicals, such as aluminum or iron salts, to water to cause small particles to clump together, forming larger particles called floc
- Disinfection: The process of killing bacteria and viruses in water using chemicals or UV light.
- Filtration: removing particles and contaminants from water by passing it through a filter.
- Flocculation: The process of forming floc, larger particles that can be removed from water more efficiently.
- pH adjustment: The process of adjusting the pH of the water to ensure it is safe for consumption.
- Pretreatment: Removing large objects and debris from the water, such as sticks, leaves, and sediment.
- Sedimentation: The process of allowing floc to settle to the bottom of a sedimentation tank, where it is removed.
- Softening: Removing minerals, such as calcium and magnesium, from hard water to make it softer.
- UV light: Ultraviolet light that kills bacteria and viruses in water.
Several chemicals are commonly used in water treatment processes to purify water and make it safe to drink or use for other purposes.
These chemicals are used for various purposes, including coagulation, disinfection, pH adjustment, and softening.
Here is a list of some of the chemicals that are commonly used in water treatment and their uses:
- Aluminum sulfate (alum): Used as a coagulant to help remove particles from water.
- Calcium hydroxide (lime): Used to adjust the pH of the water and remove impurities.
- Chlorine: Used as a disinfectant to kill bacteria and viruses in water.
- Chlorine dioxide: Used as a disinfectant to kill bacteria and viruses in water.
- Ferric chloride: Used as a coagulant to help remove particles from water.
- Hydrogen peroxide: Used as a disinfectant to kill bacteria and viruses in water.
- Ozone: Used as a disinfectant to kill bacteria and viruses in water.
- Polyaluminum chloride (PAC): Used as a coagulant to help remove particles from water.
- Sodium hydroxide (caustic soda): Used to adjust the water’s pH and remove impurities.
- Sodium hypochlorite (bleach): Used as a disinfectant to kill bacteria and viruses in water.
It is important to use these chemicals safely and in accordance with appropriate safety guidelines and regulations to ensure that the treated water is safe for consumption or other uses.
And now let’s talk about the characteristics that are considered in a filter for water treatment.
- Flow rate: The filter should be able to process water at a sufficient flow rate to meet the needs of the treatment plant.
- Pressure drops: The filter should have a low-pressure drop, which means it does not require high pressure to push the water through it. This is important to reduce the filter’s energy costs and wear and tear.
- Chemical compatibility: The filter should be compatible with the chemicals used in the treatment process and not release harmful substances into the water.
- Durability: The filter should withstand the conditions it will be exposed to and have a long lifespan.
- Cost: The filter should be cost-effective to purchase and maintain.
- Ease of maintenance: The filter should be easy to clean and maintain to minimize downtime and ensure that it operates efficiently.

Zeomedia is the only highly efficient zeolite-based filter media that has been chemically cleaned to optimize its quality and performance.
It generates 60% less waste of water and energy in backwashes per year and up to 50% better filtration quality.
It can increase the production capacity of an existing plant by at least 30% or reduce the number and sizes of filters required per project by half.
