Printing and dyeing sludge filter press is a kind of sewage treatment equipment widely used in the printing and dyeing industry, and its workflow generally includes the following steps:
1.Sludge mixing: Before the printing and dyeing sludge filter press starts working, the printing and dyeing wastewater needs to be mixed with the sludge. This sludge usually comes from wastewater treatment facilities such as sedimentation tanks or bioreactors, which contain large amounts of organic matter and suspended solids. By mixing the sludge with the wastewater, it is ensured that the contaminants in the wastewater are adequately adsorbed on the sludge for subsequent filtration and crushing treatment.
2.Sludge conveying: The mixed sludge needs to be conveyed to the printing and dyeing sludge filter press. This process is usually done using equipment such as pumps or conveyors. During the conveying process, the sludge needs to be further stirred and mixed to promote the uniform distribution and filtration of the sludge.
3.Sludge filtration: When the sludge enters the printing and dyeing sludge filter press, it will be evenly distributed on the filter cloth. Then, by applying a certain pressure, the water in the sludge is squeezed out and the solids are left on the filter cloth. This process usually takes a certain amount of time for the moisture to fully penetrate and filter the cloth outside the collection container.
4.Sludge pressing: In the filtration process, in order to improve the filtration effect and reduce the clogging of the filter cloth, the filter cloth needs to be pressed regularly. This process can be achieved by applying external pressure or by using a vacuum pump, among other things. With pressing, the water in the sludge can be further removed and the sludge becomes drier and more solid.
5.Discharge & Treatment: The sludge after filtration and pressing can be discharged and further treated. Depending on the situation, the sludge can be composted, incinerated, or otherwise recycled.
The above is the basic working process of printing and dyeing sludge filter press. In practical applications, depending on the printing and dyeing process and wastewater treatment needs, this process may need to be adjusted and optimized. In addition, in order to ensure the normal operation and use of the printing and dyeing sludge filter press, it is also necessary to maintain and maintain it regularly. For example, check whether the filter cloth is blocked, clean the filter cloth and check whether the parts of the equipment are in order. At the same time, in order to reduce the impact on the environment, it is also necessary to properly dispose of and utilize the treated sludge.
