There are different types of 150mm filter discs available for various applications and customer preferences. The following table summarizes some typical filter disc types along with their materials, porosities, filtration efficiencies, and applicable scenarios.
150mm filter discs are manufactured in different specifications depending on the application and the design of the filtration system. The key specifications in 150mm filter discs include the:
Materials
There are a number of materials used to manufacture the 150mm filter discs to meet the demands of different applications. Some filter discs suppliers offer custom filter discs according to the client's specifications. The materials used to manufacture the filter disc usually impact its performance, efficiency, and durability.
For instance, the stainless steel 150mm filter disc is resistant to corrosion. The filter disc is also durable. These two benefits make it suitable for demanding applications, such as oil and gas, water treatment, and chemical processing. Some stainless steel filter disc 150mm have micro pores that improve their filtration efficiency. Plastic filter discs, such as the polypropylene 150mm filter disc, are ideal for preventing filters from rusting or corroding. Polypropylene is lightweight but offers decent filtration. It is also suitable for industries that deal with aggressive chemicals.
Filtration Rating
The filtration rating tells the size of particles the filter disc can catch or retain. It is often determined using a standardized particle retention test. Some filter discs are made to catch larger particles to protect the filter downstream. Others are manufactured to catch tiny particles to give fine filtration.
The filtration or mesh sizes correspond to different applications. In general, a 150mm filter disc with a mesh size of 125 microns will catch particles larger than 125 microns. This is suitable for water treatment and processing industries. A 150 mm filter disc with a mesh size of 50 microns will provide better filtration, making it ideal for pharmaceuticals, food and beverage, and microelectronics industries.
Porosity and Airflow
Porosity refers to the fraction of voids or pores in the filter medium. It affects the disc's filtering efficiency, the amount of liquid or gas the filter disc can process (permeability), and the pressure drop across the filter material.
Many manufacturers subject the 150mm filter disc to stringent quality control procedures. As a result, the filter discs are durable and resistant to damage. Nonetheless, they still need care and maintenance to prolong their useful life and achieve optimal performance.
The first maintenance task is to clean the filter disc. Most 150mm filter discs can be cleaned and reused numerous times, which can lower operational costs and minimize wastage. One can use backwashing or manual washing to clean the filter disc. Backwashing involves reversing the flow. It sends water through the filter disc to remove trapped debris. The reverse water flow may dislodge some debris.
Manual cleaning is more effective than backwashing. It involves removing the filter disc from the filtration system. Rinse the surface with clean water before soaking it with a cleaning solution. The cleaning solution depends on the type of material the filter disc is made of. After soaking it for a while, use a soft brush to clean the surface and remove trapped particles. Rinse thoroughly with clean water before placing it back into the filtration system.
Many filter disc manufacturers recommend using a biodegradable cleaning solution. It is effective in removing stubborn particles, oils, and chemicals from the filter disc. It also protects the environment.
Eventually, the filter disc will reach a point where cleaning won’t improve its performance. This may be due to wear or damage to the filter disc. At this point, one will need to replace it. Choose a supplier that offers a wide selection of durable 150mm filter discs. Consider the materials and filter rating to select the most suitable filter disc for the system.
Laboratories:
In the lab, scientists often use 150mm filter paper discs to separate solid sediment from liquid samples, such as precipitates, slurries, and suspension. Choose the right type and suitability of filter paper for distinct samples so as to obtain pure filtrates. Besides, filter discs can be used in the qualitative analysis of organic compounds. By putting a small amount of a test substance on a filter paper disc, the tiny substance can be carbonized, and its residue can be easily analyzed.
Food and beverage:
Food and beverage companies commonly use filter discs in the production and quality control of filters, such as coffee filters and wine clarifications. They can also be used for microbial membrane filtration, such as water or juice. This is to ensure the absence of specific microorganisms.
Environmental monitoring:
150mm filter paper discs can also be applied in environmental monitoring. For example, filter discs can be deployed to determine air quality by particles or pollutants in the air. They can also be used to filter water samples to identify contaminants or monitor sedimentation.
Medical and healthcare:
In medical and healthcare settings, 150mm filter discs can serve to analyze samples, such as blood or urine. They can also be used to filter and separate biological samples like cells, tissues, or microbes.
When it comes to business uses, the appeal of 150mm filter discs is plentiful and straightforward. Because of their fundamental role in product quality, process efficiency, and regulatory compliance, selecting the correct 150mm filter discs is an integral part of equipment purchasing.
Material compatibility
It is crucial to choose the proper filter discs material. For instance, stainless steel filter discs offer durability in high-temperature or corrosive environments, while polypropylene discs provide a cost-effective option for non-solvent applications.
Filtration precision
Another thing that should also come into focus is filtrating accuracy while selecting 150mm filter discs. This is determined by the pore size of the filter disc. Sample protection and equipment durability are both critical downstream benefits of choosing filter discs with the correct pore size.
Flow rate
It is also essential to take into account the flow rate of 150mm filter discs. Selecting filter discs with an appropriate flow rate can assist in optimizing the process's efficiency by minimizing filtration time and ensuring sufficient sample throughput.
Quality and supplier
The disc's quality and the supplier are also important. Selecting reliable suppliers who adhere to quality standards guarantees the performance and longevity of the filter discs.
Q1: What material are 150mm filter discs made of?
A1: The 150mm filter disc can be made from various materials to suit different applications, including polyester, nylon, PP, PTFE, and others.
Q2: Are custom 150mm filter discs available?
A2: Yes, many manufacturers and suppliers offer custom 150mm filter discs. Depending on the material, pore size, shape, and quantity, when ordering, discussing unique requirements with the supplier is essential.
Q3: What is the filter principle of the 150mm filter disc?
A3: The 150mm filter disc's working principle will differ depending on the material and pore structure. Generally, a filter liquid or gas will pass through the filter disc. Larger particles or impurities cannot pass the filter medium and will be retained on the filter surface, while filtered clean liquid or gas will permeate for subsequent use.
Q4: How to store the 150mm filter disc?
A4: Store the unused 150mm filter disc in a cool, dry place away from direct sunlight and extreme temperatures. Please keep them in the original packaging or stack them neatly to avoid contamination or damage. Also, remember to store them in a place that is convenient for retrieval.
Q5: How many filtration steps does a 150mm filter disc have?
A5: Depending on the specific application and the desired level of purity, a 150mm filter disc may be employed in single or multiple filtration steps. Sometimes, it may be necessary to use a series of filter discs to achieve the required filtration.
