Municipal water supply system is an important part of urban infrastructure, and the stability of its operation and the quality of its water supply are directly related to the normal life of residents and industrial production. With the acceleration of urbanisation, the requirements for the water supply system are getting higher and higher. As an efficient water treatment equipment, gravel filter has a wide range of application prospects in municipal water supply. This paper will introduce in detail the application of gravel filter in municipal water supply and its advantages, to help municipal water supply enterprises to improve the quality of water supply and system operation efficiency.

Challenges of water quality in municipal water supply

Municipal water supply systems usually need to deal with surface water sources from rivers and lakes, which often contain large amounts of sediment, suspended solids and organic impurities. Without effective filtration, these impurities can affect the water quality of the water supply, leading to wear and clogging of pipes and equipment, and affecting the stable operation of the water supply system.

Working principle of gravel filter

The gravel filter intercepts particles in the water by means of a filtration medium (such as quartz sand). When the water passes through the filter media, the sediment and suspended matter are retained and the clean water continues to flow out. The gravel filter is equipped with an automatic backwashing system that regularly cleans the impurities from the filter media to keep the filter running efficiently.

Application of gravel filter in municipal water supply

Raw water pretreatment

In the municipal water supply system, gravel filters can be used for raw water pretreatment to remove most of the sediment and suspended solids, reduce the burden of subsequent treatment processes, and improve the processing efficiency and water quality of the entire water supply system.

Secondary Filtration

After primary treatment, the water quality may still contain certain suspended solids and particles, and the gravel filter can be used as a secondary filtration equipment to further remove residual impurities and ensure clean and stable water quality.

Pipe network protection

In the municipal water supply pipeline network system, gravel filters can be installed at the entrance or key nodes of the pipeline network to remove sediment and suspended solids in the pipeline network, prevent clogging and wear and tear of pipelines and equipment, and extend the service life of the system.

Advantages of gravel filter

Improvement of water quality

The gravel filter can efficiently remove sediment and suspended matter from water, improve the quality of raw water, and ensure the effectiveness of the subsequent treatment process and the cleanliness of the water supply.

Extend equipment life

By removing particles in the water, the gravel filter reduces the wear and tear of pipelines and equipment, prolongs the service life of the water supply system, and reduces maintenance and replacement costs.

High degree of automation

Equipped with an automatic backwashing system, the gravel filter automatically cleans the impurities on the filter media without manual intervention, keeping the filter running efficiently and reducing the cost of manual maintenance.

Stable operation

The gravel filter is easy to operate, easy to maintain and manage, and adapts to the long-term stable operation requirements of the municipal water supply system.

Case Study

Case 1: Raw water pretreatment application of a municipal water supply company

A municipal water supply company faces the problems of sediment and suspended solids when treating surface water from rivers and lakes. By installing a gravel filter, the sediment and suspended solids content in the raw water is significantly reduced, the burden of subsequent treatment processes is reduced, the treatment efficiency and water quality of the water supply system is significantly improved, and the safety of water for residents is guaranteed.

Case 2: the application of an industrial area water supply pipe network protection

The water supply pipe network of an industrial area is often affected by sand and suspended solids, resulting in frequent blockage of pipes and wear and tear of equipment. By installing a gravel filter at the entrance of the pipe network, the particles in the water are effectively removed, the smoothness of the pipe network and the service life of the equipment are greatly extended, and the water supply system operates more stably.

Conclusion

The application of gravel filter in municipal water supply, not only effectively improve the operational efficiency of the water supply system, to protect the quality of water for residential and industrial users, but also reduce the maintenance costs, improve the economic efficiency of municipal water supply system. For enterprises engaged in municipal water supply, the use of gravel filters can significantly improve water quality, protect the normal operation of water supply equipment, improve the stability and reliability of the water supply system, and thus enhance market competitiveness.

It is hoped that through this article, municipal water supply enterprises will be able to recognise the many advantages of gravel filters and apply them in actual production, thereby enhancing the operational efficiency and economic benefits of the water supply system.
