INTRODUCTION

The PP housing has many advantages. It is lightweight, has relatively high strength, excellent chemical corrosion resistance, and can remain stable in liquid environments with various chemical properties. Meanwhile, it also has good temperature resistance and can adapt to a certain range of temperature changes, providing reliable protection for internal components. The filter bag, as the core filtering element, is usually also made of PP material. This material is non-toxic and harmless, with good chemical stability. The pore size of the filter bag can be customized according to different filtration requirements, enabling it to accurately intercept impurities of different particle sizes in water, such as sediment, rust, suspended solids, and some microorganisms.

The design of the water inlet and outlet ports ensures smooth water flow in and out of the filter, while the sewage outlet is convenient for timely discharging the impurities intercepted during the filtration process. This equipment comes in a variety of specifications and can be flexibly selected based on factors such as the water treatment volume, filtration precision requirements, and installation space. It is widely used in numerous fields such as industrial production, municipal water supply, and food and beverage processing. It is easy to install, simple to operate, and runs stably and reliably, making it a capable choice for achieving water purification.

WORKING PRINCIPLE

The working principle of PP bag filters is based on the physical filtration effect of the filter bags. When the raw water containing impurities enters the filter through the inlet port, under the impetus of water pressure, the water flow will evenly flow towards the filtration chamber equipped with the filter bag.

Due to the specific pore structure of the filter bag, impurities in the water with particle sizes larger than the pores of the filter bag, such as sediment, rust, large suspended solids, and some microorganisms, will be intercepted inside the filter bag and cannot continue to pass through with the water flow. However, water and substances with particle sizes smaller than the pores of the filter bag can smoothly pass through the filter bag, gather on the other side of the filtration chamber, and then flow out from the outlet port, thus achieving the filtration of the raw water. This effectively removes visible impurities in the water, improving the clarity and purity of the filtered water and providing a better-quality water source guarantee for subsequent water use links or further water treatment processes.

MAIN PERFORMANCE AND CHARACTERISTICS

l Excellent Chemical Resistance: Thanks to the characteristics of the PP material itself, whether facing acidic, alkaline or some common chemical solutions, PP bag filters can remain stable and will not be easily corroded or damaged. This enables them to have excellent adaptability when dealing with liquids containing various chemical substances in industries such as chemical and pharmaceutical industries, allowing for long-term stable operation and ensuring the filtration effect.

l Precise Filtration Precision: With the filter bags whose pore sizes can be customized, different levels of filtration precision can be achieved. From intercepting coarse large-particle impurities to removing tiny suspended solids and microorganisms, precise control is possible, meeting diverse filtration requirements. Whether it is the electronics industry or the pharmaceutical industry, which have strict requirements for water quality, or the general pretreatment of industrial water and the purification of domestic water, it can play a good filtering role and ensure that the water quality meets the corresponding standards.

l Simple and Easy Operation: The overall structure of the equipment is simple. Workers only need to correctly install the filter bag into the support structure, then control the inlet and outlet valves of water, regularly check the clogging situation of the filter bag and replace it as needed. There is no need for complex professional knowledge and skills. Ordinary personnel can master the operation method proficiently after simple training, facilitating its quick deployment in different places.

l Stable and Reliable Operation: The combination of the PP housing and the filter bag enables the equipment to operate stably under different working conditions, such as different water flow pressures, temperature changes, and water quality differences. It is not prone to leakage, breakage, and other malfunctions, continuously providing a stable and up-to-standard water quality guarantee for the entire water use system, reducing problems such as production interruptions or water quality fluctuations caused by equipment failures, and the maintenance cost is also relatively low.

l Wide Range of Applications: Different pore specifications of the filter bag and specifications of the equipment can be flexibly selected according to different water source qualities, treatment water volumes, and specific application scenarios. It can also be used in combination with other water treatment equipment. Whether it is dealing with water in municipal water supply, industrial circulating water, domestic sewage, or seawater desalination and other fields, it can find suitable application methods, has strong versatility, and can meet diverse water treatment requirements.

APPLICATION FIELDS AND INDUSTRIES

l Industrial Field: In the electronics industry, for the preparation of ultrapure water, PP bag filters can use high-precision filter bags to intercept tiny particulate impurities in water that may affect the performance of electronic components, ensuring the production of high-quality ultrapure water and the stable quality and performance of electronic products. In the chemical industry, it can filter various chemical raw material liquids and reaction intermediates to remove impurities, avoiding adverse effects on chemical reactions and subsequent product quality and ensuring the smooth progress of chemical production.

l Pharmaceutical Industry: Pharmaceutical production has extremely high requirements for the purity of water. With its fine filtration ability, this filter can effectively intercept microorganisms and particulate impurities in water, preventing these impurities from mixing into drug raw materials or finished products, strictly controlling drug quality, meeting the strict regulations and quality standards of drug production, and providing a powerful guarantee for people's drug safety.

l Food and Beverage Industry: The production of food and beverages relies on high-quality water sources. PP bag filters can remove suspended solids, impurities that may affect taste, and microorganisms in water, ensuring that the water used for production is clean, hygienic, and odorless, thereby improving the quality and taste of food and beverage products, meeting consumers' demand for high-quality products, and enhancing the competitiveness of enterprises in the market.

l Municipal Water Supply Field: The source water for municipal water supply often contains impurities such as sediment, algae, and microorganisms. PP bag filters, as important equipment in the pretreatment or advanced treatment process, can further purify the water quality, improve the quality of the water supply, ensure the safety and hygiene of residents' water use, enable residents to use clearer and odorless drinking water, and also help to reduce the maintenance cost of the water supply pipeline caused by the deposition of impurities and extend its service life.

SUMMARY

PP bag filters, with their unique advantages of PP material, reliable working principle, and many excellent performance characteristics, have shown indispensable value in many important fields such as industry, the pharmaceutical industry, the food and beverage industry, and municipal water supply. They are like the excellent assistants for water filtration, quietly contributing to ensuring the cleanliness and efficient utilization of water resources, helping to stabilize the development of various industries and improve people's living quality.
