Understanding Water Filtration: Polypleated, Polyspun, Carbon, and UV Filtration Explained

Clean, safe water is essential for our health and well-being. Water filtration systems are designed to remove impurities and contaminants from water, so that it is safer for consumption. In this blog post, we will explore four common types of water filtration: polypleated, polyspun, carbon, and UV filtration. Understanding how these systems work can help you choose the right filtration method for your home.

1. Polypleated Filtration

Polypleated filters are a type of sediment filter made from pleated polyester. They are designed to capture and hold a high volume of particulates and sediment. Here's how they work:

• Structure: The pleated design increases the surface area of the filter, allowing it to capture more particles without clogging quickly. The polyester material is durable and resistant to chemicals and bacteria.
• Function: Water flows through the pleated polyester media, which traps sediment, dirt, rust, and other large particles. The pleats create a dense filtration barrier that captures contaminants while allowing water to flow through.
• Maintenance: Polypleated filters are often washable and reusable. Regular cleaning can extend their lifespan, making them a cost-effective option for sediment filtration.

2. Polyspun Filtration

Polyspun filters are another type of sediment filter made from spun polypropylene fibers. These filters are effective at removing fine particles from water. Here's how they work:

• Structure: Polyspun filters are composed of multiple layers of progressively finer polypropylene fibers. The outer layers capture larger particles, while the inner layers capture finer particles.
• Function: As water flows through the filter, the polypropylene fibers trap sediment, silt, sand, and other particulates. The gradient density of the filter provides efficient filtration and prevents clogging.
• Maintenance: Polyspun filters are disposable and should be replaced regularly, depending on the level of sediment in your water. They are known for their high dirt-holding capacity and consistent performance.

3. Carbon Filtration

Carbon filters are widely used for their ability to remove chlorine, organic compounds, and other impurities that affect the taste and odor of water. Here's how they work:

• Structure: Carbon filters are made from activated carbon, which is carbon that has been treated to create a highly porous structure. This increases its surface area and absorption capacity.
• Function: As water passes through the activated carbon, contaminants are absorbed onto the surface of the carbon particles. Activated carbon is particularly effective at removing chlorine, volatile organic compounds (VOCs), pesticides, and herbicides.
• Maintenance: Carbon filters need to be replaced periodically, as their absorption capacity is finite. The frequency of replacement depends on the amount of contaminants in your water and the volume of water filtered. 

Note: Carbon filters are best utilised when placed after a sediment filter as it makes the carbon filter more efficient and extends it's lifespan. 

4. UV Filtration

UV (ultraviolet) filtration uses ultraviolet light to disinfect water by killing or inactivating microorganisms such as bacteria, viruses, and protozoa. Here's how it works:

• Structure: A UV filtration system consists of a UV lamp enclosed in a protective sleeve. The lamp is installed inside a chamber through which water flows.
• Function: As water passes through the chamber, it is exposed to UV light. The UV radiation penetrates the cells of microorganisms and disrupts their DNA, rendering them unable to reproduce and causing them to die.
• Maintenance: UV lamps need to be replaced regularly to ensure effective disinfection. The quartz sleeve surrounding the lamp should also be cleaned periodically to maintain optimal UV transmission. Additionally, UV bulbs lose power over time, which is why they need to be replaced to maintain their effectiveness.
