Ensure that the polyester filter mesh is compatible with the substances it will filter. Consider the chemical properties and temperature of these substances to prevent damage to the mesh.

Maintenance and Care Tips

Cleaning Procedures

Regular cleaning is necessary to maintain the mesh's efficiency. Depending on the application, this may involve backwashing, chemical cleaning, or manual scrubbing.

Storage Recommendations

Proper storage extends the lifespan of polyester filter mesh. Store it in a dry, cool place away from direct sunlight and chemicals.

Longevity and Replacement Guidelines

Even with proper care, the mesh will eventually need replacement. Monitor its performance and replace it when you notice a decline in efficiency or significant wear and tear.

Common Issues and Troubleshooting

Clogging and Blockages

Clogging is a common issue that can affect filtration efficiency. Regular cleaning and proper pre-treatment of substances can mitigate this problem.

Wear and Tear

Over time, the mesh may show signs of wear and tear. Inspect it regularly and replace it when necessary to maintain optimal performance.

Performance Degradation

If you notice a drop in filtration performance, it could be due to damage or clogging. Identifying and addressing the root cause can restore efficiency.

Environmental Impact and Sustainability

Recyclability

Polyester filter mesh is recyclable, which contributes to its environmental friendliness. Recycling programs can help manage waste effectively.

Eco-Friendly Practices in Manufacturing

Adopting eco-friendly practices in the production of polyester filter mesh can further reduce its environmental impact. This includes using recycled materials and minimizing waste.

Comparing Polyester Filter Mesh with Other Materials

Nylon Mesh

While nylon mesh is also used in filtration, polyester offers better chemical resistance and durability, making it suitable for more demanding applications.

Stainless Steel Mesh

Stainless steel mesh is incredibly durable but significantly more expensive than polyester. Polyester provides a cost-effective alternative for many filtration needs.

Polypropylene Mesh

Polypropylene mesh is another alternative, offering good chemical resistance. However, polyester often provides better durability and temperature resistance.

Innovations in Polyester Filter Mesh

Advances in Weaving Technology

New weaving technologies are enhancing the performance of polyester filter mesh, allowing for finer and more precise filtration.

Smart Filter Meshes

Innovations such as smart filter meshes that can self-clean or indicate when they need replacement are on the horizon, promising even greater efficiency and convenience.

Choosing a Proper Water Mesh Filter Element - BoshartU

Do you have heavy sediment or large volume of scale, debris, sand, or grit needing to be removed from your water filtration system? Selecting the right mesh filter element for your sediment filter or separator starts with having a good understanding of what is on the market and what they remove from water.

Water mesh filter elements are specifically designed to remove large volumes of sediment. In this blog, we will be going over four things to consider when selecting a mesh filter element.

Housing Selection

Part of selecting an element is determining what housing you have or need. If you already have one installed, the size is listed on the inlet and outlet. When installing a new one, knowing the desired flow rate greatly helps! Check out our &#;What is the Typical Household Water Flow Rate&#; blog for more on determining flow rates.

Flow rates in sediment filters and separators have a wide flow rate overlap between sizes. For example, a 1&#; filter housing has a flow rate of 1-25 GPM and a 1-1/2&#; filter housing has a flow rate of 10-50 GPM. If your flow rate is within the range, it&#;s best to go with a smaller size to ensure the centrifugal force is adequate to separate the sand from the water. That would mean that if your desired flow rate is 20 GPM a 1&#; filter housing would be more effective.

Element Type

Elements come in two different styles, filter and separator. They both work the same way, the difference being that separators allow for more sediment to build up before it needs to be purged. Our "Understanding Sediment Filters & Separators" blog goes over the difference in more detail.

Depending on the size of the housing the filter may look different. For 1&#; housings the filters look the same between filters and separators whereas for a 1-1/2&#; and 2&#; housing, the filter has a shorter screened area and a stem holding the filter part up which gives room for the sediment to build up at the bottom.  The image shows a filter element on the left and a separator element on the right for a 1-1/2" or 2" housing.

Mesh Material

There are two main mesh materials, polyester and stainless steel. Polyester mesh is manufactured from non-corrosive material and is ultraviolet stabilized / weather resistant. Stainless steel mesh is manufactured from 316 stainless steel and is non-corrosive and durable.

Stainless steel will hold up better to sharp sediment and particles as they won&#;t rip the material. In the past polyester was the more economical option but that has changed making them both very economical options.

Mesh Size

Selecting the mesh size required is determined by what needs to be removed from the water. When talking about filtration there is different terminology that defines the size of things that will be removed. The equivalency chart below shows the comparison between the different terminologies.

The opening is the size of space between material that water and particles can pass through. The number of openings in one square inch of screen is called the mesh size. The micron rating is the distance between filter media. &#;Water Filters &#; The Basics on Micron Ratings&#; goes over this in more detail.

When using a sediment filter or separator as a pre-filter for other water filtration products, make sure that the mesh size is equivalent to a larger micron rating. For example if your filter is 80 micron you would want to use a mesh size of 140 or smaller.

To give you an idea of some common sizes, scale may be removed by using a 24 mesh element whereas sand is smaller and would require a mesh element with a 100 rating or even higher.

 

Determining the amount of sand / sediment that needs to be removed will help determine the element that is right for you. No matter which element you choose it can be removed and cleaned with a soft brush. Soaking the element in 50/50 bleach and water solution will help remove stains caused by iron, etc. Be sure to rinse the element thoroughly before it is installed again. Now you have a better understanding of what goes into choosing a water mesh filter element and what the options are.
