1. There is sand and mud in the groundwater of the well water, and the water body is turbid
There is sediment in the well water and groundwater because when the deep water is pumped by the raw water pump, some underground sediment is pumped up together, and the sediment is loosened, so the well water becomes turbid. Of course, it is also caused by water pollution on the one hand. At this time, when well water or groundwater is used as the water source, it is necessary to use a quartz sand filter to filter the sediment before use.
2. The water quality of the river is turbid
Due to the influence of weather, upstream sewage, soil conditions and upstream engineering projects, the water quality of river water is not very stable. For example, in the case of heavy rain in the upper reaches of the river, the water quality contains a lot of impurities such as sediment, the water quality is turbid, and the content of suspended solids is high.
When using river water as the water source, it is necessary to use a quartz sand filter to filter impurities such as suspended solids, sediment, and organic matter in the water.
3. Impurities and suspended solids in tap water
Tap water is due to the pollutants deposited on the pipeline or the suspended solids caused by the backwashing and positive washing of the water plant, or the impurities generated by some water sources that are not good enough to meet the standard of tap water, then we will deal with them. Quartz sand Due to its natural nature, the filter does not contain chemical substances, and is widely used in tap water. It has strong interception and filtration functions, and can filter the suspension in tap water.
4. After sewage treatment, the suspended matter still does not meet the standard
The sewage cannot reach the standard after biochemical treatment and sedimentation treatment. Because sedimentation treatment is only rough treatment compared to quartz sand treatment, the quartz sand filter has high precision, which can reach about 50 microns in general, so after sand filter treatment, it can be very It is good to improve the water quality of the effluent. It has been proved that the quartz sand filter has a good effect on the sewage terminal filter. If the activated carbon filter is added for adsorption, the effect will be better.
In practice, quartz sand filters are widely used in various industrial wastewater treatment fields such as textile printing and dyeing wastewater treatment, paper industry wastewater treatment, industrial chemical fiber wastewater treatment, food industry wastewater treatment, electronic machinery wastewater treatment, medical wastewater treatment, etc. Applications.
