As a pretreatment, the laminated disc filter device is widely used in industrial and commercial fields, such as seawater desalination, food, textile, metallurgy, plastics, medicine, building materials, papermaking, HVAC systems in industrial and commercial buildings, irrigation, wastewater treatment, sewage Regeneration, municipal water supply, water plants, large power plants, chemical companies, and emergency filtration, etc., are related to the safe and effective operation of the entire set of devices.
1. Application of Laminated Filter in Membrane Pretreatment
1.1 Ultrafiltration/microfiltration pretreatment
The hole diameter of vacuum fiber filament: 0.8mm, 0.3mm
The function of the laminated filter: filter out the solid particles larger than the pore size of the membrane, avoid the blockage of the vacuum membrane wire, and protect the membrane wire from being scratched.
1.2 Reverse osmosis/sodium filtration pretreatment
When the inlet water conditions are poor, such as river water and reclaimed water, the laminated disc filter can be used in the pretreatment of other filtration equipment.
When the water inlet conditions are good, such as tap water and deep well water, the laminated filter can be used in front of the security filter.
In general, the role of disc filters in membrane pretreatment is to classify and filter equipment or to protect subsequent equipment and reduce the filtration load of subsequent equipment.
2. Application of laminated filter in circulating water filtration
Among industrial water, cooling circulating water accounts for 70-80% of the total water consumption. The cooling water system handles a large amount of water and is difficult to handle. However, the operating water temperature is low, so the water quality requirements are lower than that of boiler water.
Among them, the closed cycle process requires that the cooling water is not exposed to the air, the water loss is small, and the salt content in the water changes little. Generally used for generators, internal combustion engines, or a single heat exchange equipment with special requirements. In the open cycle, the cooling tower is used to cool the water, and the cooling water is in contact with the air. The content of suspended solids and ions in water is constantly changing. Need to add cooling water, need to drain.
Laminated disc filters can be used in the following areas:
Pretreatment of makeup water: coagulation, sedimentation, filtration, softening, desalination
Circulating water filtration treatment: full flow filtration, side filtration (circulating water volume 1-5%)
Sewage treatment: filtration, desalination, and reuse (to achieve zero discharge of circulating water)
3. Application of Laminated Disc Filter in Agricultural Irrigation
The irrigator in sprinkler drip irrigation is called the heart of the sprinkler drip irrigation system, and its water flow aperture is generally very small, which requires that the irrigation water cannot contain dirt that causes the irrigator to block. Therefore, the irrigation water must be purified to ensure sprinkler irrigation. The key to the proper functioning of a drip irrigation system.

4. Application of laminated disc filter in ion exchange pretreatment
Ion exchange is a water treatment method that removes harmful ions from water by exchanging ions on resin with ions in water.
The laminated disc filter can be used for pre-filtration in the early stage, resin capture in the later stage, and filtration of the salt system.
