Production method of rural water filter pool First, according to the number of water users and water consumption, determine the total water consumption and the time requirements for supplying water, and then select the equipment processing capacity and size according to the maximum hourly water consumption. For filters, they can generally be selected locally according to the local building materials. most of them use pressure steel filter containers to rinse with the corresponding water pump. regular manual operation can be done.The steel container can use 50 centimeters thick quartz sand and add 30 centimeters thick granular activated carbon to strengthen the filtration effect. The specific size is as follows: the area of the filter can be divided by the maximum filtration speed according to the maximum hourly water consumption, and the cross-sectional area of the filter container can be obtained.
