1.Automatic Valveless Gravity sand Filter is gravity flow filtration，that is using the gravity of the water body to automatically run the stable filtration and washing process.
2.In the process of operation, manual operation is not needed, the labor intensity of workers is effectively reduced, and the effluent quality is good.
3.The ordinary sand filter material can complete the filtration of surface water. When it is properly reformed, other corresponding filter materials can be used to realize the softening and desalting of industrial water with the removal of iron and manganese removal.

The filtration process of Automatic Valveless Gravity Filtration
Through the precipitated or clarified water, into the siphon riser through the water tank and the U tube, the water baffle in the top cover is evenly distributed into the filter layer, and the water is filtered from top to bottom through the filter layer. After the filter water is filtered, the small resistance water distribution device is collected and entered into the clean water area (that is the water tank). Storage, when the water level rises to the outlet pipe, the filtered water flows to the sink.
Application
1. When it is used for filtration treatment in waterworks, the suspended solids in the influent should be less than 15mg/l and the suspended solids in the effluent are less than 3mg/l.
2. Automatic Valveless Gravity sand Filter for circulating cooling water filter treatment, the suspended solids are generally 15-30mg/l, and the suspended solids of the effluent are generally less than 5mg/l.
3.It is used for "coagulant treatment" when the suspended solids are 50-100mg/l, and the suspended solids of the effluent are generally less than 5mg/l.
Equipment characteristics
1. No connection is required for valves in it, and the siphon principle is applied skillfully to achieve full automatic operation.
2. It is set integration, easy maintenance, safe and reliable.
3. Our product has low labor intensity and is easy to manage.
4. It can realize computer automatic detection and control.
