Understanding the Mechanics of Pool Filtration

At Omega Pools, we believe that knowledge is power, especially when it comes to maintaining crystal-clear swimming pools. Today, we’re diving deep into the technical aspects of pool filtration systems, a crucial component in keeping your aquatic oasis clean and inviting.

The Three Main Types of Pool Filters

1. Sand Filters: These use specially graded sand to trap particles as water passes through.

2. Cartridge Filters: Utilizing pleated polyester or paper elements to capture debris.

3. Diatomaceous Earth (DE) Filters: Employing fossilized exoskeletons of tiny marine organisms for ultra-fine filtration.

The Filtration Process

The filtration cycle begins when water is drawn from the pool through the skimmer and main drain. It then passes through the pump, which creates the necessary pressure to push the water through the filter media. As the water moves through the filter, contaminants are trapped, and clean water is returned to the pool via the return jets.

Pressure Gauges and Backwashing

Most filtration systems include a pressure gauge that indicates when the filter needs cleaning. As debris accumulates, the pressure increases. When it rises 8-10 PSI above the clean filter reading, it’s time for backwashing (for sand and DE filters) or cleaning (for cartridge filters).

The Role of Turnover Rate

Turnover rate refers to the time it takes for the entire volume of pool water to pass through the filtration system once. An efficient system should have a turnover rate of 8-12 hours, ensuring that all the water is filtered multiple times per day.

At Omega Pools, we specialize in designing and installing filtration systems tailored to each pool’s unique requirements. Understanding these technical details helps us provide our clients with the most effective and efficient pool maintenance solutions.

Remember, a well-maintained filtration system is key to enjoying a clean, safe, and inviting pool all season long!
