Equipment introduction
sand filter
The sand filter is composed of one or more standard high-speed sand tank units, with a unique water distributor and water collector inside, and a unique automatic flushing valve, which can realize multiple standard high-speed sand tanks one by one during normal system operation. Separate backwash, fully automatic program control. It has the advantages of small water consumption for backwashing, convenient equipment installation, and easy operation; the equipment has a large flow rate and requires no maintenance; according to different user requirements, there are two series of vertical and horizontal types, which are suitable for water quality treatment needs in many fields.
Application range
Electric power, reverse osmosis pre-stage, petrochemical, fine chemical, food and beverage, agricultural irrigation, automobile, industry, metallurgy, papermaking, medicine, microelectronics, environmental protection water treatment and other industries.

PET Bottle Making Machine is suitable for producing PET plastic containers and bottles in all shapes.
Equipment advantages
Product Features
The filter unit has various specifications from 24 inches (500mm) to 96 inches (2400mm), and can be installed in different ways. The filter can be used as an independent filtration system, using the water supply pump in the existing process, and if it is used as a side filter, it can also be equipped with its own pump. The filter can also be installed on the common pipeline with multiple processing units, which can realize the unlimited filtering capacity of this system. There are three methods of backwashing of the filtration system: manual, semi-automatic and fully automatic, which can be started by manual buttons, PLC, pressure difference or management system respectively. The backwash cycle and backwash time are adjustable, and the factory setting is 3 minutes. This control is realized by PLC automatic filter control system.
1. High filtration speed and low pressure loss completely solve the problems of slow filtration speed and small flow rate of ordinary mechanical media filters.
2. Modular setting, small footprint, less piping, and low investment. The floor area is reduced by more than 40%, and the amount of piping engineering is reduced by more than 50%.
3. Manual, semi-automatic and fully automatic backwashing options are available to fully meet your needs.
4. The backwash water source can be selected from the system, water tower or external water source, and can be switched automatically (on special request).
5. Multiple units can be combined, and the processing flow can be expanded arbitrarily.
6. The shell and pipeline are made of carbon steel Q235B, and can also be made of stainless steel.
working principle
filter state
The shallow sand filter is composed of several filter units arranged side by side. When the system is in the filtering state, the unfiltered water is evenly distributed through the unique water distributor developed by ourselves, and the water passes through the packing layer (refined uniform-grained quartz sand) in the filter in a laminar flow state. When water flows through the packing layer, impurities are trapped in the packing layer. There are multiple evenly distributed water collectors at the bottom of the filter, which collect and lead out the filtered water evenly, and filter in advection, so that the filter can filter at a high flow rate and still achieve a better filtering effect.
Backwash status
As impurities continue to accumulate in the packing layer, the internal head loss will continue to increase. When the loss of the inlet and outlet water pressure head reaches the set value, the system will automatically activate the constant pressure difference device to switch to the backwashing state. Easy to clean accumulated impurities.
When the system is in the state of backwashing, the filtration continues, and the standard unit sand tank to be backwashed does not filter, while other standard unit sand tanks in the system are still filtering. Part of the filtered clean water is used to backwash the standard unit sand tank, and the rest is still sent to the user. The backwash sewage is discharged through the backwash drain of the hydraulic valve. In the high-speed sand tank high-efficiency filtration system, the special design of the water collector can make the fillers scrub each other to maximize the efficiency of backwashing, reduce the required backwashing water (clean water), and at the same time, there is no leakage during backwashing. material phenomenon. The backwashing time of a standard unit sand tank is 3 minutes. After the backwash is over, the internal pressure head loss of the standard unit sand tank is reduced to a reasonable range. The constant pressure device gives a recovery signal, and the hydraulic valve returns to the filtering state. The next standard unit sand tank Then it is ready to enter the backwashing state. The system can also control the backwashing by time. The default time is 4 hours, and the time can be adjusted on site according to the working conditions.
