Definition and Composition of Diatomaceous Earth
Diatomaceous earth (DE) is a naturally occurring sedimentary rock that is composed of fossilized diatoms, microscopic algae with hard shells made of silica. This powder is mined from ancient dried lakebeds and marine deposits, and is available in various grades ranging from food-grade to pool-grade.
- Food-grade DE is used in many industries, including food, cosmetics, and agriculture. It is considered safe for consumption by the Environmental Protection Agency (EPA) as long as it does not contain more than 1% crystalline silica.
- Pool-grade DE is used for pool filtration systems, and contains a higher percentage of crystalline silica than food-grade DE. It should never be ingested or inhaled.
- Celite is a brand name for a specific type of DE that is commonly used in pool filtration systems.
- Amorphous silica is a non-crystalline form of silica that is sometimes used as a substitute for DE in pool filtration systems. It is considered less hazardous than crystalline silica.
The composition of DE varies depending on its source and the specific conditions under which it was formed. Some DE may contain other minerals, such as calcium, magnesium, and iron, which can affect its effectiveness as a pool filter media.
How Does Diatomaceous Earth Work in Pools?
Diatomaceous earth (DE) is a porous, natural substance that filters out contaminants in pool water. As water passes through the DE filter, tiny particles are trapped between the microscopic pores of the DE.
DE works by creating a barrier that captures particles as small as 5 microns, including bacteria, algae, and debris. DE filters are considered to be the most effective type of pool filter available, as they can remove up to 99% of contaminants from pool water.
DE filters work in conjunction with your pool pump. As water is circulated through the pool pump, it passes through the DE filter, where the DE captures any contaminants present in the water. The filtered water is then returned to the pool, providing clean and clear water for swimming.
The Filtration Process Using Diatomaceous Earth
Diatomaceous earth (DE) is a fine powder that is added to pool filters to clean and purify the water. The filtration process using DE involves a few steps that work together to remove impurities and particles from the water.
- Precoat: The DE powder is first mixed with water to create a slurry, which is then poured into the filter tank. The slurry coats the filter grids and creates a layer that captures debris and contaminants.
- Filtration: As water flows through the coated filter grids, impurities and particles are trapped in the DE layer. The clean water is then returned to the pool.
- Backwashing: Over time, the DE layer becomes saturated with debris and must be removed. This is done by reversing the flow of water and forcing it out of the filter tank. The used DE is then discarded and the filter grids are cleaned.
When done properly, the filtration process using DE can effectively remove particles as small as 5 microns, leaving the pool water clean and clear.
Is Diatomaceous Earth a Safe Pool Filter Option?
Diatomaceous earth (DE) is a popular pool filter option due to its high efficiency and ability to capture small particles. However, many pool owners wonder if it is safe to use. The short answer is yes, but with some precautions.
DE can pose a health risk if it is inhaled or ingested in large amounts. To minimize this risk, it is important to handle DE properly and avoid direct contact with the skin and eyes.
Additionally, DE can affect the pH balance of pool water and cause irritation to skin and eyes if not properly maintained. It is important to regularly test and adjust the pH levels to prevent any issues.
When used correctly, DE is considered a safe and effective pool filter option. It is also environmentally friendly and can be disposed of easily.
