Sand filtration is indeed an important process to ensure the quality of irrigation water by removing impurities and protecting farmland from grit, contaminants, and diseases. The use of sand filters, in combination with other filters, can effectively remove particulate matter, reduce turbidity, and adsorb and remove organic matter and ions.
Beite Sand Filtration offers a wide range of sizes and installation options for its sand filtration system, which can be used as stand-alone filtration systems or installed in multiple treatment units on common piping to allow for unlimited filtration capacity. The backwashing function of the Beite filter system is available in manual, semi-automatic, and fully automatic modes, which can be activated by manual button, PLC, differential pressure control, or management system, respectively. The backwash cycle and backwash time can also be adjusted to suit the specific needs of the users.
The working principle of sand filters is straightforward yet highly efficient. During the filtration process, pressurized water flows into the distribution system and is evenly distributed across the filter media layer. As the water passes through this layer, the suspended particles and impurities are trapped and retained by the filter media, while the clean, filtered water is collected and discharged from the system.
As impurities accumulate within the filter media over time, the pressure loss across the system increases. In response, the sand filter automatically switches to the backwashing state. In this mode, pressurized water is introduced through the water collection device, flowing in the reverse direction and flushing the filter media. This action dislodges the trapped contaminants, effectively cleaning the filter and discharging the impurities from the system.
The simplicity of this design, coupled with its efficient filtration and self-cleaning capabilities, makes sand filters a reliable and widely-used water treatment solution. By effectively removing suspended solids and impurities, these filters help maintain the quality and performance of water systems across a variety of industrial, commercial, and municipal applications.
Overall, sand filtration is an essential process in agricultural irrigation, and the Beite sand filtration system offers a reliable and efficient solution for removing impurities and ensuring the quality of irrigation water.
The product features of this mechanical media filter include a high filtration speed, low pressure loss, and modular design. It has a small footprint, requires less piping, and can save on investment costs. The backwashing water source can be selected from the system, water tower, or external source water, and the backwashing process is highly efficient with a short backwashing time. The shell is made of carbon steel with a phosphate surface treatment, and the pipeline material is made of carbon steel sprayed with resin or PVC. The valve is made of cast steel or PVC plastic, and the pipe interface adopts a standard DN interface. The filter should be checked and cleaned regularly to ensure that it can operate normally, and attention should also be paid to the working pressure and water quality.
There are several important notices that should be taken into consideration when selecting and using this filter.
Firstly, when selecting a manual backwashing sand and gravel filter, it is recommended to use more than two tanks.
Secondly, the filter should be selected according to the design flow to avoid a decrease in filtration accuracy caused by the sand bed tube surge effect.
Thirdly, a large flow rate design can increase the head loss in the system.
Fourthly, the filter should be backwashed when the import and export pressure drop is higher than 0.05-0.07MPa.
Fifthly, a backpressure valve should be added in the backwashing main if the system pressure is too high.
Lastly, the filter should be checked and cleaned regularly to ensure that it can operate normally, and attention should be paid to the working pressure of the filter and the water quality to ensure that the quality of the irrigation water meets the needs of the crops.
