FAQ’s on Filter Leaves

Maintaining adequate filtration that meets or exceeds requirements depends in large part on the quality of the filters that are used in the process. The filtration process is one that needs to be repeatable over time, meaning the custom wire mesh panels that are used to filter out impurities must be high-quality and resistant to damage in order to be effective. Filter leaf fabrication requires exceptional engineering, but also a degree of experience and technique to ensure that all parts work together as a cohesive whole. Here are some of the most frequently asked questions about filter leaves and the filtration process.

Filter Leaves,

What Are Filter Leaves and How Are They Used?

Pressure leaf filters are utilized in various industries, cleaning wastewater and effectively removing solid material or oils from fluids. They are generally used to help purify and decontaminate liquids and are often found in situations where toxic substances are being used. Since they are in such challenging environments, filter leaves are made of custom wire mesh panels that are manufactured to capture the “cake” — or buildup of solids — that is what actually filters the liquid or oils.

What Are the Components of Filter Leaves?

While they come in a variety of sizes and styles, there are a few key components that leaf filters share:

  • — Filter media, also known as the screen surface, are engineered specifically to offer a clean release of the cake buildup and resist clogging. They are often matched with a pre-coat media that helps provide a more consistent outcome.
  • — Flow chambers create a more stable life while helping provide a uniform collection of the effluent.
  • — Outlets provide a leak-proof seal to the collector, accommodating the total flow of the leaf filter.
  • — Center collection elements are often used on larger filter leaves to help assure an even flow across the face of the collector.

Each element of the filter leaves work together to help ensure smooth, consistent operation and output that meets or exceeds defined tolerances.

Are There Challenges With Low-Quality Filter Leaves?

As with any product that is directly associated with wastewater or other toxic items, low-quality or broken filter leaves could be quite damaging. Whether the problems are caused by normal wear and tear, inadequate cleaning or outright damage to the screens, good care and maintenance are required to keep everything moving smoothly through your leaf filters. Keeping the correct distance between the filters can help reduce the possibility of damage from rubbing against other filters, too.


At a glance, here are the most important things that you need to know to understand how filter leaves work and when they are used in industrial situations.

  • Filter leaves are one of the oldest forms of filtration
  • — Components of filter leaves include: the screen surface (filter media), flow chamber and outlets
  • — Leaf filters are used to clean or remove solids from a mixture, allowing only the liquid to flow through the filter
  • — The quality and engineering of filter leaves dictate their effectiveness and durability
  • — It’s vital to use filter leaves that provide a uniform flow and product stability
