What is municipal sewage？
Including domestic sewage, industrial wastewater and runoff sewage, it is collected by the urban drainage pipe network and transported to the sewage treatment plant for treatment.Urban sewage treatment process should be adopted according to local conditions. The natural purification of the water body and the purification role of the sewage in the process of utilization should be considered according to the utilization or discharge direction of the urban sewage. Determine the wastewater treatment degree and the corresponding treatment process.
The treated sewage, whether used for industrial, agricultural or external discharge, shall meet the national standards.Urban sewage treatment is divided into three levels, namely, primary treatment (mechanical treatment), secondary treatment (biological treatment), and tertiary treatment (advanced treatment).The primary treatment mainly adopts grille, sand sink tank, sedimentation tank and other structures to remove the undissolved suspended objects in the sewage.Secondary treatment mainly removes the colloids and soluble organic matter from the water outlet of the primary sedimentation tank.Typical equipment is a biological aeration tank (or biofter) and a secondary sedimentation tank.tertiary treatment mainly removes secondary effluent nutrients (nitrogen and phosphorus) and other biodegradable substances.
The main methods are flocculation, filtration, adsorption, ion exchange and other materialization methods.The purpose of tertiary treatment is to avoid water eutrophication or reclaimed water.Urban sewage treatment. Generally, the primary treatment must be handled. Secondary processing is the main body. tertiary processing is rarely used.
The GFS tank has developed with high strength Titanium Rich Steel (TRS) plates, which can work perfectly with our glass frit. The strength and flexibility of steel and high corrosion resistance of glass which will make a proven products to install in many application, such as municipal waste water, industrial waste water, drinking water, sludge diposal, manure waste, etc.
The benefits of GFS Tank,
1. Good Anti-Corrosion Performance
2. Smooth, anti-bacteria
3. Wear and scratch resistance
4. High acidity/alkalinity tolerance
5. Fast Installation
6. Less maintenance cost and easy to repair
7. Possible to combine other technology (Anaerobic Digester)
