The composition of sludge mainly depends on the sewage water quality, treatment process and methods. The composition of sludge mainly depends on the sewage water quality, treatment process and methods. There are mainly the following types of sludge: primary
Sedimentation Tank sludge, secondary sedimentation tank sludge, screen slag, sand settling sediment and scum, etc. The primary sedimentation tank sludge is mainly composed of organic matter, while the secondary sedimentation tank sludge contains organisms and chemicals. Sludge contains a lot of water. The moisture content of sedimentation tank sludge is generally above 95%. The moisture content can greatly affect the volume of sludge. If the moisture content is increased from 99.5% to 95%, the sludge volume can be reduced to the original 1 /10.
The characteristic of the warm film wave machine is that it can perform secondary drying and pressing of the wave cake. The special design of its filter chamber allows it to automatically close the feed smoke after filling the filter chamber with filter cake and pass it into the filter chamber. The gas or liquid causes the
Filter Cloth to expand and deform, thereby achieving a secondary pressing effect on the filter cake and further reducing moisture. Further introduction of gas will further reduce the moisture in the filter cake. The high-pressure air passes through the filter cake and separates the capillary water, structural water and other moisture in the filter cake. This is the blow drying method.
Generally speaking, from the perspective of urban sewage treatment, Senjie Environmental Protection believes that the resource utilization of urban sewage has become an important issue in water-scarce areas, because urban sewage has been proven to be a reliable water resource, and with the advancement of water treatment technology, sewage regeneration technology Has been widely used. In this case, the structure of the
Filter Press uses hydraulic compression and automatic pressure maintaining devices, which can use the pressure generated by the filter cloth to create a filter cake with a higher solid content. The entire operation process is simple. , safe, and with high automation procedures, saving time and effort, environmental protection, and reducing costs.
