The disc filter as an efficient protection for pre-filtration
In the world of water treatment, efficiency and durability of equipment are crucial to ensure a consistent, high quality supply. One of the essential components to protect the first stages of treatment, such as chlorination, filtration, activated carbon and softening, are disc filters. These devices play a vital role in preventing sediments larger than 130 microns from reaching the deep-bed equipment, thus preventing premature clogging and prolonging its service life.
What are disc filters?
Disc filters are mechanical filtration devices that use a series of stacked slotted discs to create a three-dimensional filter. Water passes through the slots in these discs, which are arranged to capture unwanted particles and sediment. This type of filtration is highly effective in retaining particles of different sizes, especially those larger than 130 microns.
Why are disc filters so important?
In any water treatment system, equipment protection is critical to ensure efficient and long-lasting operation. Disc filters play a crucial role in this task, acting as an initial barrier that prevents large particles from clogging downstream equipment.
Benefits of disc filters in industrial water treatment
Protection of deep bed filters
One of the main benefits of disc filters is their ability to protect deep bed equipment such as sand, zeolite, anthracite filters. By capturing large sediments before they reach this equipment, disc filters prevent premature saturation. This not only prolongs the life of the filter media and equipment, but also saves on electrical energy due to frequent cleaning and maintenance downtime of the filtration train.
2. Water saving
Unlike deep-bed filters, which require frequent backwashes to maintain efficiency, disc filters save significantly more water. Backwashes are processes in which the flow of water through the filter is reversed to remove trapped particles. This process consumes large amounts of water, which can be costly and unsustainable. Disc filters, because of their efficient design, require fewer backwashes, resulting in considerable water savings and more economical operation.
Simple and efficient maintenance
Disc filters are known for their ease of maintenance. Their modular design allows for easy cleaning and replacement of discs, which minimizes downtime and reduces maintenance costs. This is especially important in water treatment systems that require continuous and reliable operation.
4. Adaptability and flexibility
Disc filters can be adapted to a wide variety of applications and water treatment system configurations. Their flexibility allows them to be easily integrated into pre-existing stages of the treatment process, they are compact and modular, improving protection and efficiency without the need for significant system modifications. In summary, disc filters are an effective and efficient solution to protect the first stages of water treatment. Their ability to retain sediments larger than 130 microns, save water and reduce the frequency of backwashing, together with their easy maintenance and adaptability, make them an ideal option to optimize the performance and durability of water treatment systems. Implementing disc filters not only improves the quality of treated water, but also contributes to a more sustainable and economical operation.
Where to place disc filters for filter media protection or cartridges?
Option 1: Prefiltration of multimedia or deep bed filters
Improved performance with reduced water consumption during cleaning in filtration systems using media such as zeolite, green sand, activated carbon and ion exchange resins.
Option 2: Multimedia filter cleaning water filtration
Facilitates re-injection of water used in cleaning or backwashing back into the system, thus reducing overall water consumption.
Option 3: Microfiltration cartridges pre-filtration
Increases filtration efficiency and reduces the frequency of replacement of microfiltration cartridges, especially if they are absolute grade cartridges for the food, beverage, pharmaceutical, and general industrial industries.
