Types of Filters and Their Uses
In this section, we will explore different types of filters used in whole house water treatment systems, primarily focusing on sediment filters and iron filters. We will learn about their uses and how they contribute to maintaining water quality in households.
Sediment filters are designed to remove larger particles such as sand, silt, rust from plumbing lines, and dirt from your water supply. They play a crucial role in protecting your pressure tank and other appliances from damage caused by these particles. Installing a sediment filter before the pressure tank is recommended, as it ensures that the tank is filled with clean water, preventing dirt from entering and prolonging the life of the appliance.
There are various types of sediment filters, including:
- Spun polypropylene filters: These filters are made of melted polypropylene strands that are spun together to create a filter. They are effective at trapping particles and have a relatively long lifespan.
- Pleated filters: These filters have a large surface area due to their pleated design, which increases their capacity to trap particles. They can be cleaned and reused multiple times before replacement is necessary.
- String wound filters: Made from tightly wound strings, these filters can trap particles within their layers. They are available in various micron ratings to suit different water treatment needs.
Iron filters are specifically designed to remove excess iron from water supplies, improving water quality and preventing staining, unpleasant tastes, and odors. These filters are typically installed after the pressure tank to ensure a high enough flow rate for backwashing, which is a process that helps flush out accumulated particles.
There are several types of iron filters, some of which include:
- Oxidizing filters: These filters use a process called oxidation to convert dissolved iron into solid particles, which can then be removed through filtration. Oxidizing filters can use air, ozone, or chemicals such as chlorine or potassium permanganate to achieve this.
- Ion exchange filters: Also known as water softeners, these filters use a resin bed to exchange iron ions for sodium ions, effectively reducing and removing iron in the water.
- Birm filters: Birm is a granular filter media that works as a catalyst to oxidize iron, allowing the iron particles to be trapped and removed during the filtration process.
In summary, when planning a whole house water treatment system, it is essential to consider the installation location and selection of appropriate filters. Sediment filters should be installed before the pressure tank to protect it from damage, while iron filters are recommended after the pressure tank for efficient backwashing capabilities.
To ensure optimal operation of your whole house water filter, it’s essential to consider the impact of water pressure and pressure pumps. A pressure pump is responsible for maintaining consistent water pressure (measured in psi) throughout your home, which is crucial for the proper functioning of appliances and fixtures.
When deciding whether to install a water filter before or after the pressure tank, keep in mind that a filter placed before the tank can help protect it from sediment buildup, which can damage the tank and pressure switch. Conversely, a filter installed after the pressure tank is beneficial for backwashing and optimal flow rates in the case of iron filters.
However, placing a filter system before the pressure tank can also lead to reduced water pressure if the filter becomes clogged with debris. In this situation, the pressure tank will need to compensate, but this can sometimes result in inadequate water flow through your home.
