Water disinfection is used to kill bacteria, viruses, and other harmful microorganisms. Common methods include:

• Chlorination: Uses chlorine to disinfect water; widely used in potable water and swimming pools.
• Chlorine dioxide: Effective against bacteria and biofilm; commonly used in cooling towers and industrial water systems.
• UV disinfection: Uses ultraviolet light to inactivate microorganisms without adding chemicals.
• Ozonation: Uses ozone gas for strong disinfection; often used in high-quality water treatment systems.
• Copper-silver ionization: Releases copper and silver ions to control bacteria, mainly used in cooling and hot water systems.

Side stream filtration removes suspended solids from a portion of the circulating cooling tower water. Common options include:

• Multimedia sand filters: Use layers of sand and gravel to remove dirt and suspended particles.
• Automatic self-cleaning screen filters: Use fine screens and automatic backwashing.
• Disc filters: Use stacked discs to trap fine particles.
• Cartridge filters: Used for fine filtration where water quality requirements are high.

pH control in swimming pools is done using an automatic pH controller. The system works as follows:

• A pH sensor continuously measures the pool water pH.
• The controller compares the measured value with the set point.
• If pH is high, acid dosing is activated; if pH is low, alkali dosing is activated.
• A dosing pump injects the required chemical automatically.
  This helps maintain a stable and comfortable pH range, typically between 7.2 and 7.6.

Water filter cartridges are used for fine filtration and are available in different types, such as:

• String wound cartridges: Made by winding polypropylene yarn; good for general filtration.
• Melt blown cartridges: Made from polypropylene fibers; widely used for sediment removal.
• Pleated cartridges: Have a large surface area; suitable for higher flow rates.
• Activated carbon cartridges: Used to remove chlorine, odor, and organic contaminants.
• Resin cartridges: Used for softening or specific contaminant removal.

A vortex impeller pump is a type of centrifugal pump designed to handle liquids containing solids or debris. The impeller creates a vortex inside the pump casing, allowing solids to pass without direct contact with the impeller. These pumps are commonly used in sewage, wastewater, and sludge applications.

A chilled water pressurization unit is used in HVAC systems to maintain the required pressure in closed chilled water circuits. The unit typically consists of a pressure vessel, pump, control panel, and safety devices. It compensates for pressure losses, prevents air ingress, and ensures stable system operation in chilled water and cooling systems
