what is a sand pool filter

Introduction:

If you are a pool owner or planning to build a pool, you must be aware of the importance of water filtration to maintain cleanliness and hygiene. There are three types of pool filters: cartridge, diatomaceous earth (DE), and sand. In this article, we will explore what a sand pool filter is, how it works, and its benefits over other pool filter types.

What is a Sand Pool Filter?

As the name suggests, a sand pool filter uses sand as a filtering medium to trap and remove impurities from the pool water. The sand acts as a natural sieve that captures dirt, debris, and other contaminants, preventing them from returning to the pool. A sand pool filter consists of a tank filled with sand, a distribution system, and a multiport valve that controls the water flow and filter functions.

How does a Sand Pool Filter work?

When the pool water enters the filter tank, it passes through the sand bed, which traps and holds the dirt and debris on its surface. The water then flows through the laterals and into the filter outlet, returning to the pool cleaner and clearer. To keep the sand bed effective, you need to backwash the filter regularly, which reverses the water flow and flushes out the trapped particles, preventing sand compaction and channeling.

Benefits of a Sand Pool Filter:

1. Low Maintenance:

Compared to other filter types, sand pool filters require minimal maintenance. Sand lasts for many years and only needs to be replaced every 5-7 years, depending on usage and water quality. Cleaning the filter involves backwashing, which can be done in just a few minutes, without disassembling or replacing any parts.

2. Cost-Effective:

Sand pool filters are one of the most cost-effective options for pool owners. The initial cost is lower than DE filters, and sand is cheaper than DE powder. Additionally, sand pool filters consume less energy, as they only require a low horsepower pump to operate, reducing your monthly electricity bill.

3. Effective Filtration:

Sand pool filters are capable of removing particles as small as 20 microns, making them effective at trapping algae, pollen, and dust. They can also withstand high flow rates and pressure, allowing them to handle heavy usage and large pools.

4. Eco-Friendly:

Sand is a natural and renewable resource, making it an eco-friendly option for pool filtration. Sand does not release any harmful chemicals or byproducts into the environment, and it can be disposed of safely.

5. Easy Installation:

Installing a sand pool filter is straightforward and can be done by DIY enthusiasts. You only need to follow the manufacturer's instructions and connect the filter to your pool plumbing. Once installed, your sand pool filter is ready to use.

Conclusion:

A sand pool filter is an effective, low-maintenance, and cost-effective option for pool owners who want to keep their pool water clean and clear. They are versatile and can handle various pool sizes and heavy usage. By using sand as a natural filtering medium, they offer eco-friendly filtration without compromising on effectiveness. If you are considering a new pool filter, a sand pool filter is definitely worth considering.
