Shanghai Jiuching introduces you to backwashing filter equipment, which is a novel filter equipment. Backwashing filter has many advantages and can avoid the disadvantages of traditional filters. Advantages, backwash filters also have reasonable cost of sewage treatment, which is more suitable for sewage treatment than traditional filters. Backwash filters are very flexible and can be operated under aerobic and anaerobic conditions, and can be used individually or in multiple steps. The backwash filter unit has the function of filtering raw water and actively cleaning and discharging the filter elements, and the system provides continuous water supply while cleaning the wastewater. Compared to conventional filters, the backwash filter unit has a high degree of initiative, large treatment capacity, self-cleaning and effluent discharge, and uninterrupted water supply.

Backwash filters are very important for wastewater treatment and environmental protection. In many ways backwashing filter plants are ideal for controlling wastewater. Backwash filters not only provide good pollution control, but also have a very reasonable cost.

1. The backwashing filter specification should be matched with the installation pipeline. When the filter flow cannot meet the pipeline requirements, two (or more) filters can be installed in parallel or side-by-side.

2. The backwash filter should be installed as close as possible to the place where the system is to be protected. Use inlet low pressure, so it should be installed close to the pressure source.

3. The backwash filter should be installed in series in the piping system. To ensure uninterrupted water supply to the backwash filter during shutdown for maintenance, it is recommended that a bypass be installed in the system and filter ball valves should be set at the inlet, outlet and bypass of the filter. If there is a possibility of backflow, a check valve should be installed at the filter outlet.

4. When choosing the model of backwashing filter, pay attention to the temperature of the water flowing through the automatic self-cleaning filter does not exceed its adaptation temperature.

5. The backwashing filter installation site has three-phase 380V industrial frequency AC (three-phase four-wire system). The sewage pipe should not exceed 5 meters to avoid back pressure.

6. Backwashing filter DC system should pay attention to filtration accuracy, pretreatment, pressure matters and intermittent system precautions.

7. Backwashing filter reasonably choose the installation environment, pay attention to waterproof, rainproof, moisture-proof.

However, it is important to note that the backwash filter system will be out of operation for an extended period of time or out of seasonal operation. Before the system stops operating, add an appropriate amount of corrosion inhibitor to the water and take measures to protect the system from moisture and humidity.

Through the above introduction hope you have a certain understanding of backwashing filter, for more details please consult our official website.
