Multimedia Filter - Impurity Buster & Water Purification Pioneer

With a combination of multiple filter media, it constructs an efficient filtration system, precisely intercepting various impurities in water and significantly improving water quality, providing reliable pretreatment guarantees for various water - using scenarios.

I. Product Introduction

The multimedia filter is a professional water treatment device designed based on the principles of physical interception and adsorption. Inside the device, multiple filter media with different characteristics are filled, such as quartz sand, anthracite, manganese sand, activated carbon, etc. Through scientific layered collocation, it forms a multi - layer filtration barrier. It can effectively remove impurities in water such as suspended solids, colloids, rust, sediment, some organic matters, and residual chlorine, greatly reducing water turbidity. It is an indispensable key device for water quality pretreatment in industrial production, municipal water supply, environmental protection treatment, and other fields. The device adopts a modular design, and the filter media combination and device specifications can be flexibly adjusted according to actual needs. It is easy to operate and has a low maintenance cost.

II. Working Process

1. Raw Water Introduction: The raw water enters the device from the top inlet of the filter through the pipeline under pressure and is evenly distributed on the surface of the filter media layer.

2. Layered Filtration and Purification:

• Upper - layer Coarse Filtration: The large - particle quartz sand or anthracite at the top layer first intercepts larger - particle impurities in the water, such as sediment and large - particle suspended solids, initially reducing water turbidity and playing a pre - filtration role.

• Middle - layer Fine Filtration: The filter media with slightly smaller particle sizes in the middle layer (such as quartz sand, manganese sand) further intercepts fine particles, colloidal substances, and some iron and manganese ions, conducting fine - grained filtration of the water quality.

• Bottom - layer Adsorption: The highly adsorptive filter media such as activated carbon at the bottom layer uses its rich pore structure to adsorb residual chlorine, organic matters, odors, and trace heavy metal ions in the water, completing the deep purification.

3. Purified Water Output: The purified water that has been filtered and adsorbed through multiple layers of filter media flows out from the bottom outlet of the filter and enters the subsequent water treatment links or is directly put into use.

4. Backwashing and Regeneration: As the filtration continues, more and more impurities are intercepted by the filter media layer. When the pressure difference between the inlet and outlet of the filter reaches 0.05 - 0.1MPa or the running time reaches the set duration (usually 8 - 12 hours), the backwashing program is automatically started. During backwashing, the water flows upward from the bottom, loosening and tumbling the filter media layer, washing away the intercepted impurities, which are then discharged through the top 排污口. After the backwashing is completed, a short - time forward flushing is carried out. After ensuring that the effluent water quality meets the standard, the device resumes normal filtration.

• Pharmaceutical Industry: As a pretreatment device for pharmaceutical water, it removes impurities in water, meeting the strict requirements of GMP for pharmaceutical water.

VI. FAQ

1. Can the multimedia filter remove heavy metal ions in water?
   Some filter media in the multimedia filter (such as manganese sand and activated carbon) have a certain adsorption effect on heavy metal ions such as iron and manganese, but the removal capacity is limited. For water sources with high heavy metal ion content, it is recommended to add deep - treatment processes such as reverse osmosis and ion exchange after multimedia filtration to effectively remove heavy metal ions.

2. How to determine whether the filter media needs to be replaced?
   It can be judged by observing the effluent water quality after backwashing and the change in the operating pressure difference of the filter. If the effluent turbidity still cannot meet the standard after backwashing, or the pressure difference of the filter remains continuously high during normal operation and cannot return to normal after frequent backwashing, the filter media needs to be checked and replaced if necessary. In addition, when the filter media reaches its normal service life of 3 - 5 years, replacement should also be considered to ensure the filtration effect.

3. Do professionals need to install the equipment?
   Although the installation operation of the equipment is relatively simple, to ensure correct installation and stable operation of the equipment, it is recommended that professionals carry out the installation and debugging. Professionals can reasonably plan pipeline connections and electrical wiring according to the actual on - site situation, and conduct trial operation and parameter optimization of the equipment to ensure the normal operation of the equipment in the future.

VII. Conclusion

With its innovative combination of multiple filter media, excellent filtration performance, intelligent and convenient operation management, and wide application range, the multimedia filter has become an ideal pretreatment device in the water treatment field. Whether it is to ensure the stable operation of industrial production or improve the water quality of urban and rural residents, it can play an important role.
