Water Disinfection

Water Disinfection Systems

Water disinfection systems utilize chemical methods to attack and eliminate germs (fungi, bacteria), and viruses. The process of these systems differ from antiseptic kinds that disallow the spread of microbiological substances through various means, other than completely destroying them.   

Water disinfection acts as an essential element for the production of high quality water that is capable of being consumed, used throughout the house, or for other purposes.  

Where can water disinfection be used?

  • Ground water

Pure Aqua has remained as a global leader in supplying high quality water disinfection systems, such as ultraviolet sterilizers and chemical dosing systems for the purposes of providing physical and chemical treatment. These systems are ensured to provide optimal primary and post-treatment solutions when disinfecting water. 

We provide a complete range of water disinfection systems for various applications including disinfection of chemicals, UV and ozonation. Our services for custom in-house design, and manufacturing of chemical dosing and industrial water systems are suitable for a wide range of applications.

Chemical Dosing

Our chemical dosing systems are designed for precision, durability, and complementary to handle as many different kinds of chemicals. Our chemical feed systems can be used with many water treatment systems, our team must dose chemicals to gain a balanced pH level and eliminate impurities. Impurities can cause bacteria such as algae to grow in untreated water, so it is imperative for our chemical feed systems to remove these contaminants. Certain chemicals will also need to be pumped manually to achieve the required water quality. They are added with the use of a dosing pump and chemical tank, and then installed to the water treatment system in a contained process.

Ultraviolet Sterilization

Ultraviolet (UV) is one of the most prevalent types of disinfection among water treatment systems, and is employed in different applications, such as industrial, commercial, and municipal applications. The purpose of Ultraviolet or UV sterilizers are to make water healthier and prolong the life of the water that has been treated and processed.

Ultraviolet sterilization is a physical treatment, which prevents any alteration to the chemistry, and addition of coloring, flavor, smell and taste to the water. For this reason, UV has earned its reputation as one of the most proven techniques in water disinfection.

The word “sterile” is defined as being free from living germs or microorganisms. A UV sterilizer supremely cleans water and kills bacteria and microorganisms that can infest water even after it has been treated.

Many water purification systems take advantage of a UV purifier even after processing their water. This is a well-known practice. Pure Aqua highly recommends UV sterilizers as a post treatment when treating water.

Throughout the years ultraviolet technology has become well established as a chosen method for effective and economical water disinfection.

UV sterilization claims many advantages:

  • All microorganisms are virtually susceptible to ultraviolet disinfection.
  • For every penny of operating cost, hundreds of gallons of water are purified.
  • No additional chemicals are added and there’s no danger of overdosing.
  • Once the water leaves the purifier, it is ready for use with no further contact time required.
  • It has simple and easy to install and maintain.
  • Compact units need a small space to operate and store.
  • UV sterilizers deliver ongoing or intermittent disinfection without special attention or measurement.
  • There are no detection of chlorine taste or corrosion problems.

Ozone Disinfection

Due to its effective sterilization and oxidation abilities, ozone disinfection is another commonly used water treatment application. The ozone disinfection can be added in water treatment systems during many stages, such as the pre-disinfection, intermediate disinfection, or final disinfection stage. We recommend adding ozone during the pre-oxidation stage, before the introduction of sand or carbon filters. Once ozonation is installed then these filters can thoroughly eliminate any remaining organic matter, which is vital for the final disinfection stage.

The key benefits of this process is: 
  • Elimination of microbiological organisms (pesticides)
  • Removal of organic and inorganic matter
  • Elimination of other organic, and inorganic substances
  • Reduction of decontamination derivatives
  • Increased efficiency disinfection
  • Removal of odor and taste
