Shallow sand filter

Shallow sand filterProduct Introduction

Fully automatic speed filter sand cylinder, also known as bypass filter（Shallow sand filter）It is commonly used as a bypass filter in central air conditioning water treatment and industrial circulating water treatment, also known as a side filter sand filter. It can also be used throughout the entire process for swimming pool circulating water processors, large-scale artificial landscape water circulating processors, and agricultural irrigation. The cylinder body is made of carbon steel material, which is not easily worn, easy to operate, and provides an economical and high-performance configuration. The designed water distributor ensures even water flow. In addition to quartz sand, other filter materials available for selection include manganese sand, activated carbon, anthracite, fiber balls, resin, zeolite, etc. Easy to install, maintain, and upkeep.

Shallow sand filterProduct Point:

The key to filtration lies in a large filtration area, reliable mechanical design, simple structure, good water distribution, and uniform water collection. The multi-point gap water distribution method and the densely arranged water collection cap water collection method have been proven to be practical on carbon steel filters, followed by their application on speed side filters, resulting in a uniform filtration rate. Make the LJAGF series filters a good choice for high water volume, poor water quality, and requirements.

Easy to operate:By using differential pressure switches, electric butterfly valves, and PLC control systems, the automation and intelligence of filter operation and backwashing can be achieved without the need for tedious manual backwashing work. Cleaning; A smaller amount of backwash water can enable the system to operate in continuous cleaning mode.

durable and long-lastingThe quality of corrosion-resistant and wear-resistant materials, combined with the design, ensures that the filter does not require maintenance for a long time.

Shallow sand filterTechnical Specifications:

Working pressure: 0.25MPa-1.6MPa Input power supply: 220-380V, 50Hz

Pressure loss: 0.01MPa~0.03MPa (initial resistance) Applicable water temperature: 0~90 ℃

Filtering degree: 0.5-2mm Working mode: fully automatic (pressure difference control, timing control)/manual control

Working status:

When the system is in a filtered state, unfiltered water passes through the water distributor and, in conjunction with the casing, reaches the filter material layer (sand) inside the filter in a nearly laminar state. When water flows through the filter layer, impurities are trapped within the filter layer. Pass the filtered water throughwater collectorCollect and flow out evenly. Advection filtration determines the flow rate at which the filter can still achieve good filtration.

Backwash status:

As impurities accumulate in the filter layer, the head loss will continue to increase. When the head loss reaches a certain set limit, the system will automatically switch to backwash mode to clean the accumulated impurities.

Backwash is carried out every time the pressure difference reaches 0.05-0.07MPa, and after the backwash is completed, the pressure difference returns to the initial 0.02-0.03MPa.

Backwashing applies the principles of backwashing and surface scrubbing.

Points of the filtering system:

1. Control mode, can be manually/automatically controlled

2. Homogeneous filter material, filtration efficiency

3. Epoxy sprayed carbon steel material is used both inside and outside

4. Water distributor, simple, uniform, and reliable;

5. The processed water collector has a service life of over 10 years;

6. Performance: The system undergoes complete testing before leaving the factory.

7. Easy installation: During installation, simply connect the inlet and outlet water and sewage pipes for use, without the need for on-site fabrication.

8. Low backwash water consumption: Using homogeneous filter material extends the backwash cycle, greatly reducing the total backwash water consumption.

9. Backwash efficiency: water collector.
