Disinfection System

KUOSI provides disinfection solutions for municipal, industrial and recreational water applications. Our full range of disinfection technologies includes analyzers and process controllers, ozone generator systems, sodium hypochlorite generation systems and more. We offer solutions to meet virtually any disinfection need, large or small, and have an experienced sales and customer support team to help meet any challenge.

ozone generator

Ozone Generator

Ozone generators are designed for laboratory and research in water, and industrial research and wastewater treatment facilities.

sodium hypochlorite generator

Sodium Hypochlorite Generator

Sodium hypochlorite generators produce low strength disinfectants on demand through the electrolysis of brine solutions.

Water treatment disinfection systems inactivate disease-causing microorganisms in water. Chemical processes, such as chlorination and ozonation, and physical processes, such as ultraviolet (UV) irradiation, are selected according to water quality and treatment goals. Disinfection is usually one stage in a treatment process; it does not by itself remove every contaminant or make all water suitable for drinking or reuse.

Application

  • Rainwater Treatment
  • Wastewater Treatment
  • Groundwater
  • Surface Water
  • Seawater Desalination
  • Reverse Osmosis

FAQ

A disinfection system treats water to inactivate pathogenic microorganisms using a controlled chemical dose or a physical process such as UV irradiation. Its design depends on water quality, target organisms, and intended use. For drinking water, the WHO Guidelines for Drinking-water Quality (fourth edition incorporating the first, second and third addenda), Table 7.10, specify that E. coli should not be detected in any 100 mL sample of water directly intended for drinking. This guideline must be interpreted with the full WHO guidance and applicable national or local requirements; it is not a stand-alone guarantee of water safety.

Ultraviolet disinfection system uses the principle of ultraviolet disinfection, modular design, the size and dose of the module with the different treatment capacity and water quality and custom design, the disinfection module is placed in the disinfection channel, together with other parts on the shore and PLC control unit constitutes the disinfection system.

Ultraviolet disinfection system is generally composed of seven parts:

  1. ultraviolet lamp module;
  2. junction box;
  3. Ballast control cabinet;
  4. PLC main control cabinet (man-machine interface box);
  5. Pneumatic device and air compressor;
  6. lifting device;
  7. overflow weir and related auxiliary accessories

Common water treatment options include chlorination, ozonation, and ultraviolet (UV) irradiation. They use different mechanisms and are selected for the water quality and treatment objective.

  1. Chlorination: chlorine-based chemicals, including sodium hypochlorite, inactivate susceptible microorganisms and can provide a disinfectant residual.
  2. Ozonation: ozone is used as an oxidizing disinfectant; an adequate ozone dose and contact time are required.
  3. UV irradiation: ultraviolet light inactivates microorganisms. Performance depends on the delivered UV dose and the water’s ability to transmit UV light.

Chemical disinfectants used in water treatment include chlorine-based products, chlorine dioxide, ozone, and chloramine. Their suitability depends on the application and treatment design.

  1. Chlorine-based products, such as sodium hypochlorite, for controlled dosing.
  2. Chlorine dioxide, used where the treatment design calls for this disinfectant.
  3. Ozone, used in suitably designed ozone disinfection systems.
  4. Chloramine, used by some water utilities to maintain a disinfectant residual in distribution systems.

Disinfectant selection must consider target organisms, water chemistry, dose, contact time, residual requirements, and disinfection by-products. Medical surface-disinfection and sterilization categories should not be applied directly to water treatment. For background on chlorine and chloramine, see the CDC water disinfection overview.
