Lenticular filters are a popular choice across industries like pharmaceuticals, food and beverage, and chemicals due to their unique design and efficiency. We’ll cover their functionality, advantages, providing a definitive guide to help you understand how lenticular filters can meet your filtration needs.
What is Lenticular Filter
Lenticular filtration are a type of depth filtration system, designed for high-flow liquid filtration. Lenticular filters are specialized filter media designed in a stack of pleated filter sheets. They provide highly efficient filtration for liquids, particularly in applications where high flow rates and fine particle removal are needed.
A lenticular filter is a modular filtration system made up of stacked circular filter units. These units are designed with depth filtration media and are thermally welded to ensure a sealed structure, preventing product bypass. The unique pleated design maximizes the filtration surface area, allowing for high efficiency and capacity.
The lenticular filter’s main distinguishing feature is its accordion-like structure, which significantly increases surface area for enhanced filtration. The filter is composed of a series of discs, or “cells,” stacked and connected to a central core. Each cell consists of a rigid polypropylene support screen sandwiched between two circular depth filtration media discs, all thermally bonded together. The completed units are then thermally bonded to the central core to prevent product bypass.
What is Lenticular Filter Housing
Filter housings are the protective enclosures that hold and support the filter elements within a filtration system. They are designed to ensure the safe, efficient operation of filters while maintaining a secure seal to prevent leaks. Filter housings come in various sizes and materials, depending on the specific requirements of the filtration process.
In the case of lenticular filters, lenticular filter housings are typically constructed from stainless steel or other corrosion-resistant materials, providing durability and resistance to harsh chemicals and temperatures. The lenticular housing is designed to hold the lenticular filter stack and allow for proper fluid flow, ensuring the filter works at optimal efficiency.
How Does a Lenticular Filter Work?
A lenticular filter operates with a modular design of stacked filter units. Each designed with depth filtration media. These filters are efficiently capture particles as the liquid flows through the filter layers. The pleated design of each unit increases the surface area, allowing for higher flow rates and improved filtration capacity.
As liquid enters the lenticular filter housing, it flows through the stacked filter cells. They are composed of a rigid polypropylene support screen and depth filtration media. The particles are captured within the depth of the media, ensuring thorough removal of contaminants. The filter’s accordion-like structure further enhances its filtration performance by maximizing the available surface area for filtration.
The liquid continues its flow towards the central core, passing through the series of filter cells, where contaminants are trapped at various depths. This design prevents any bypass and ensures the liquid is filtered at an optimal level before exiting the filter.
4 Reasons to Choose Lenticular Filter
Lenticular filters are alternative to sheet filters that utilizing similar filtration media for comparable applications. Unlike traditional sheet filters, lenticular filtration provides a more efficient and effective filtration solution.
Easy to Use and Maintain
Lenticular filters are incredibly easy to install and dismantle, with minimal maintenance required. Only a few key components need to be replaced, such as the bottom silicone or fluoropolymer gasket, a 1.5-inch gasket for the tri-clover connections, and occasionally the plastic parts of the compression device. This simplicity makes operation and upkeep much more efficient.
Space-Saving Design
Lenticular filter housings occupy less space while offering a larger filtration surface area. This compact design provides high performance even in limited spaces. Additionally, lenticular housings can be mounted on casters or rails for greater mobility and flexibility.
Reusable and Regenerable Media
The filter media in lenticular filters can be backwashed and forward flushed multiple times during use, extending the life of the media and reducing the frequency of media replacement. Compared to paper-based media, this regenerative design improves throughput by at least 50%, making it more cost-effective over time.
Compatibility with Bottling Lines
Lenticular filters are especially suited for operation alongside bottling lines. The design enables them to handle start-stop cycles efficiently and ensures smooth filtration, even with varying flow rates. This makes them one of the most efficient choices for bottling line applications and ensures high performance in industries that require high throughput.
Filter Aids in Lenticular Filtration
Lenticular filters often incorporate filter aids into their depth media to enhance filtration efficiency. Filter aids are powdered substances added either to the solution being filtered or integrated directly into the filter media. By embedding filter aids into lenticular filters, the challenges of dealing with loose powders are eliminated.
Two commonly used filter aids in lenticular filters are Diatomaceous Earth and Activated Carbon.
Diatomaceous Earth
Diatomaceous Earth (DE) is a white, chalky powder composed of microscopic silica structures known as diatoms. Its highly porous nature makes it an effective filter aid for removing fine solids. The honeycomb structure of the diatoms contains variously sized pores, which trap even tiny particles such as bacteria and viruses.
When integrated into lenticular filter media, DE forms a “porous cake” that effectively captures particulates from liquids. Moreover, our DIEdisc® I lenticular filter not only provides efficient filtration but also preserves the original color and odor of the filtrate.
Activated Carbon
Activated carbon is particularly useful for removing color and odor from liquids, especially in the filtration of botanical extracts. It effectively binds to plant dyes like chlorophyll, which contribute to the murky green color of crude extracts. By removing these colorants, activated carbon helps produce a clear liquid.
Our ACCdisc® I lenticul filter offer an efficient, hassle-free solution for eliminating unwanted color and odors without the need to handle loose carbon powders.
Applications of Lenticular Filtration
Lenticular filtration is highly effective in processes where liquids are heavily loaded with solids or require stringent contamination control. Its specialized design and depth filtration media efficiently capture fine particles, enhance clarity, and ensure the integrity of the product.
- Botanical Extracts:Lenticular filters are widely used in the production of botanical extracts to remove impurities, plant residues, and colorants such as chlorophyll.
- Wine Clarification: Lenticular filters help improve the clarity of wine by removing suspended solids, yeast, and other impurities.
- Beer production: lenticular filtration removes unwanted particles, including yeast, proteins, and other solids, ensuring a clear and stable beer with improved shelf life.
- Juice Production: Lenticular filter is used in juice production to remove pulp, sediments, and other particulates, ensuring a smooth and visually clear final product.
- Edible Oil Processing: Lenticular filters effectively remove impurities, such as fine particles and contaminants, from edible oils, improving their clarity and extending the shelf life of the product.
