What is water disinfection?
Pathogenic bacteria are removed, deactivated, or killed during water disinfection. Microorganisms are destroyed or rendered inactive, halting development and reproduction. Drinking contaminated water will make individuals sick if microbes are not eliminated, from it.
How is drinking water disinfected?
Disinfection can be accomplished with either physical or chemical disinfectants. Organic pollutants in water that act as nourishment or habitat for microbes, are also removed by the agents.
Disinfectants must also have a residual impact, meaning they must remain active in the water after disinfection.After disinfection, a disinfectant should prevent pathogenic germs from developing in the pipes and contaminating the water.
Chemical disinfection of water
The following disinfectants can be used to chemically disinfect water:
- Chlorine (Cl2)
- Chlorine dioxide (ClO2)
- Sodium hypochlorite (OCl-)
- Halogens including bromine (Br2) and iodine (I)
Physical disinfection of water
The following disinfectants can be used to physically disinfect water:
· Ultraviolet radiation (UV)
· Radiation from electronic devices
· Gamma radiation
What is the process of disinfection?
Chemical inactivation of microbiological contamination in untreated or natural water, is typically one of the last steps in reducing harmful bacteria, in drinking water.
The combination of water purification procedures (oxidation, coagulation, settling, disinfection, and filtering) results in safe (drinking) water after manufacturing.
To safeguard the water against microbial contamination in the water distribution system, many countries add a disinfection step at the end of the water purification process.
Disinfection prevents microorganisms from multiplying in the water during distribution.
Using ultraviolet (UV) radiation to disinfect drinking water and wastewater
It is a dependable method of disinfection that involves exposing contaminated water to UV light rays. UV radiation penetrates an organism's cell walls and damages the cell's genetic material, rendering reproduction impossible.
UV light is produced by striking an electric arc through low-pressure mercury vapour in a particular lamp.This lamp delivers a broad spectrum of radiation with strong peaks at UV wavelengths of 253.7 nanometres (nm), which research has proved to be the most effective UV wavelength range for destroying bacteria.
UV disinfection can eliminate the threat of waterborne pathogens to human health, without the formation of disinfection by-products that can be produced by drinking water chlorination. From common bacteria, E-Coli, to Cryptosporidium, UV disinfection systems are capable of offering excellent water treatment to assure pathogen inactivation and safe drinking water.
Benefits of Using UV
· It does not have any known harmful or significant non-toxic by-products.
· There is no risk of overdose.
· Cleans up some organic pollutants as well.
· Produces no volatile organic compound (VOC) or harmful air pollutants.
· It has no on-site odour and no odour in the finished water product.
· Requires minimal contact time.
· It does not necessitate the storage of hazardous materials.
· Improves the taste of water by destroying some organic pollutants and nuisance bacteria.
· It has no effect on water minerals.
