The purpose of sediment filtering is to remove fine particles or colloidal solution chemicals in water resources. If these particles are not removed, they can cause damage and even block other fragile membranes in the dialysis water. It is the oldest and very simple method of cleaning water.
Therefore, this process is generally a preliminary treatment of water purification, or when necessary, multiple filtering devices are added to the pipeline to remove large residues. There are many kinds of filter devices used to filter floating fine particles, such as filter screens, sand filter devices (such as quartz sand, etc.) or membrane filter devices.
If the particle size exceeds the size of the hole, it will be blocked. Regarding the positive ions dissolved in the water, they cannot be blocked. If the filter device is not replaced or cleaned for a long time, more and more particles will accumulate in the filter device, and the water output and pressure will gradually decrease. Everyone uses the water pressure and the pressure difference to distinguish the degree of the filter device. Therefore, the filter device should be replaced on time to remove the accumulated residue, and the filter device should be replaced at a fixed time.
Sedimentation filtration method is a difficult problem that is worthy of concern. Since fine particles have been banned and accumulated, this chemical substance will breed germs and release toxic substances through the filter device, causing the heat source to reflect, so it is often necessary Change the channel and inlet and outlet gas pressure of the filter device to increase the basic principle of five times the original, and the filter device must be dismantled and replaced.
