The multi-tank parallel shallow sand filter is composed of one or more standard high-speed filtration units. The water flow through the internal water distributor and water collector can effectively remove particles and reduce turbidity by using different media. If loaded with a specific filter material, such as activated carbon, anthracite, can also be adsorbed to remove the corresponding organic matter, ions and so on.
The multi-tank parallel shallow sand filter can be used as a stand-alone filtration system using the supply water pump in the existing process or, if used as a by-filter, can be equipped with its own pump separately. Multiple processing units can also be installed on the common pipe, so that the system can achieve unlimited filtration capacity. The backwashing of the filter system can be done by manual, semi-automatic and fully automatic, which can be started by manual button, PLC, pressure difference or management system respectively. Backwash cycle and backwash time can be adjusted, set to 3 minutes when leaving the factory. This control by DCS automatic filter control system to achieve the user can also choose PLC control system, can achieve centralized or remote communication and other high requirements of control.
When the system is in the filtering state, the pressurized water flows into the water distribution system from the filter unit inlet and uniformly reaches the filter material layer. When the water flow filter material layer, the suspended matter is intercepted by the filter material, the bottom of the filter with a precision gap collector, filtered clean water is uniformly collected, and flow out of the filter.
With the continuous accumulation of impurities in the filter material layer, the pressure loss continues to increase. When the pressure difference increases to a certain set value or reaches the set cleaning time, the system will automatically switch to the backwash state. Pressurized water enters the filter material layer through the water collection device and washes it to make the trapped pollutants fall off and discharge out of the filtration system. After the backwash lasts for at least 2 minutes, the valve automatically switches the system to the filtered state.
1. The core components are imported with original packaging.
2. Backwashing effect is better, sand running rate is lower.
3. The water collector can be made of stainless steel /ABS for longer service life.
1, high filter speed, low pressure loss, completely solve the problem of slow filter speed and small flow of ordinary mechanical medium filter.
2, modular setting, small area, less distribution pipe, less investment. The area is reduced by more than 40%, and the quantity of piping is reduced by more than 50%.
3, manual, semi-automatic, automatic backwash optional, fully meet your needs.
4, backwashing water source can be selected in the system, water tower or external water source, and can be automatically switched (special requirements).
5, 16 "-96" model unit selection, multiple unit combination, processing flow can be arbitrarily expanded.
