Water treatment filler is a functional material used in water treatment equipment, usually made of plastic, ceramic, metal or fiber. Their main role is to remove suspended solids, organic matter, heavy metal ions and other pollutants in water through physical filtration, chemical adsorption or biodegradation, so as to improve water quality.
First, the main application of water treatment filler in sewage treatment
1, the application of biological filters
Biofilter is one of the common processes in wastewater treatment, and the water treatment filler is the core component of the biofilter. The surface of the filler provides a place for microorganisms to attach and grow, forming a biofilm. These microorganisms are capable of decomposing organic matter in the water and converting it into harmless substances. Common biological fillers include plastic Bauer rings, ceramic rings, etc.
Advantages: Improve the attachment area of microorganisms and sewage treatment efficiency.
Applicable scenes: urban sewage treatment plant, food processing wastewater treatment, etc.
2, the application of the filtration process
In the physical filtration process, water treatment fillers (such as fiber balls, quartz sand, activated carbon, etc.) are used to intercept suspended solids, colloids and other impurities in water. Through the combination of multi-layer filler, it can realize the gradual filtration of pollutants of different particle sizes.
Advantages: simple operation, good filtration effect.
Applicable scenes: drinking water pretreatment, industrial wastewater filtration.
3、Application in adsorption process
Activated carbon filler is widely used in sewage treatment because of its strong adsorption capacity. It can effectively remove organic matter, odor, pigment, and some heavy metal ions in water.
Advantages: strong adsorption capacity, a wide range of applications.
Applicable scenes: chemical wastewater treatment, printing and dyeing wastewater treatment, and so on.
4、Application in nitrogen and phosphorus removal
In sewage treatment, nitrogen and phosphorus are the main pollutants leading to the eutrophication of water bodies. Some special water treatment fillers (such as termite) can promote the process of nitrogen and phosphorus removal through biochemical reactions, thus reducing the content of nitrogen and phosphorus in the water body.
Advantages: environmentally friendly, in line with strict emission standards.
Applicable scenes: municipal sewage treatment, agricultural wastewater treatment, etc.
Second, the advantages of water treatment filler
High efficiency: the filler provides a huge specific surface area, which can significantly improve the removal efficiency of pollutants.
Economy: long service life of the filler, low maintenance cost, suitable for large-scale application.
Environmental protection: through biodegradation and physical adsorption, reduce the use of chemicals, reduce the risk of secondary pollution.
Flexibility: different types of filler combinations can be selected according to different water quality and treatment needs.
Conclusion
As an important part of the sewage treatment process, water treatment filler has a wide range of applications and significant results. Whether it is municipal sewage or industrial wastewater, choosing the right filler can significantly improve treatment efficiency, and reduce operating costs, while contributing to environmental protection. In the future, with the progress of technology, water treatment fillers will play a more important role in the field of sewage treatment.
