Foam Inserts for Water Filters

Foam Inserts – Key Information

Foam inserts are most commonly made from polypropylene non-woven fabric with a special structure that provides very high-level filtration. Polypropylene foam inserts are used in water treatment systems for the mechanical removal of solid contaminants. Polypropylene foam features a porous structure that effectively traps particles such as sand, rust, sediments, and other suspensions. Thanks to their construction, these inserts ensure high flow capacity and long lifespan while maintaining low water flow resistance.

Polypropylene foam inserts are valued for their chemical and physical resistance, making them a suitable choice for use in various conditions, including the food and pharmaceutical industries as well as in household installations. Polypropylene, as a non-toxic and corrosion-resistant material, guarantees safe use and no impact on the taste or smell of the filtered water. The polypropylene insert can be used as a pre-filter (so-called pre-filter), protecting more advanced filtration systems from damage caused by larger contaminants.

What contaminants do polypropylene foam inserts remove?

Polypropylene foam inserts are effective filtration elements that remove various mechanical contaminants from water. Their porous structure can trap particles of different sizes, making them versatile and efficient.

Mechanical contaminants removed by foam inserts

• Sand and silt – foam inserts effectively remove fine particles of sand and silt that can enter water supply systems from natural water sources such as rivers, lakes, or wells.

• Rust – metallic contaminants such as rust can appear in water due to the corrosion of pipes and other metal elements of water supply installations. Foam inserts trap these particles, preventing them from reaching the final water collection points.

• Organic and inorganic sediments – these inserts are also effective in removing various organic sediments (e.g., plant residues) and inorganic sediments (e.g., pollen and clay).

• Solid particles – foam inserts can trap larger solid particles, such as fragments of rocks, soil, or other materials that may be present in raw water.

Applications of foam inserts

Drinking water filtration

Foam inserts are commonly used in household drinking water filtration systems. Their main advantage is their ability to retain mechanical contaminants, making the improvement in the quality of water supplied to the tap quickly noticeable. Filters with foam inserts can be installed at various points in the water supply system, such as inline filters or under-sink systems.

Industrial water filtration

In industry, foam inserts are used in various technological processes where the removal of mechanical contaminants from water is necessary. They can be used in cooling systems, production processes, and wastewater treatment. Due to their efficiency and durability, they contribute to maintaining high water quality used in industrial procedures.

Foam filters in reverse osmosis systems

Foam filters perform excellently in reverse osmosis (RO) systems as one of the stages of preliminary filtration. It can therefore be stated that they serve as sedimentation filters, whose main task is to protect more advanced and expensive osmotic membranes from damage and premature wear.

The role of foam filters in reverse osmosis systems

• Mechanical pre-filtration – foam filters act as the first line of defense against mechanical contaminants such as sand, silt, rust, and other solid particles. Thanks to the porous structure of polypropylene foam, they effectively trap these contaminants, preventing them from passing into subsequent filtration stages.

• Protection of the osmotic membrane – osmotic membranes are delicate and precise filtration elements that can be damaged by contact with larger particles. Foam filters protect membranes from clogging and damage, which increases their lifespan and efficiency.

• Reduction of system load – by removing larger contaminants at the preliminary stage, foam filters reduce the load on other elements of the RO filter, such as carbon filters and the membranes themselves. This allows the entire system to operate more efficiently and consume less energy, leading to lower operating costs.

Benefits of using foam inserts

Filtration efficiency

Foam inserts are characterized by high efficiency in removing mechanical contaminants. Thanks to their porous structure, they can trap particles of various sizes, resulting in better quality of filtered water. The size of the pores in the foam can be adjusted to specific needs, allowing for the optimization of the filtration process, ensuring clean water with optimal parameters.

Durability and resistance

Foam inserts are exceptionally durable and resistant to chemical and mechanical factors. For this reason, they can be used in various conditions, both in household filtration systems and in more demanding industrial applications. The high durability of foam inserts translates into a longer lifespan and less frequent need for replacement.
