Why does sludge need to be dewatered? This is a question that many customers wonder about. I will analyze the reasons for the deep dewatering of the sludge for everyone. If you dehydrate the sludge produced in industry, it is difficult to clean and transport, which will not only cause environmental pollution but also a series of other problems.
1. The effect of deep dewatering of sludge is obvious. The water content of sludge produced by sewage treatment plants, chemical plants, and industrial enterprises is mostly above 90%, even as high as 99%, which is fluid. The sludge in this state is large in volume, easy to spread, difficult to transport, and difficult to store. Therefore, it is necessary to reduce the water content of the sludge and reduce its volume. The water content of the sludge treated by lzzg sludge press dryer can reach 15%-50%, and the water content of sludge with 95% water content can be treated to 40% water content, and the volume is reduced by 11 times. The effect can be seen.
2. Deep dehydration of sludge effectively eliminates odors, germs, and other harmful substances. The sludge is deeply dehydrated to form a dry hard mud cake with extremely low moisture content. The harmful substances flow out with the water, and the mud cake is non-sticky, the surface is dry, and no longer has an odor, which can stabilize the sludge.
3. Mud cakes with low moisture content are easier to use as resources. According to relevant national regulations, the sludge cannot be landfilled until the moisture content of the sludge reaches 60% or less. The sludge can be mixed with other substances and sent to the calciner for combustion in a hard mass. The moisture content of the sludge in this state is about 50%. Plate and frame filter presses, membrane filter presses, chamber filter presses, and other equipment cannot meet the standards after being processed, and they need to be dried with drying equipment, or the mud cakes can only meet the standards after several days of drying. Waste of resources and time is also contrary to the original intention of environmental protection. The sludge cake treated by LZZG’s sludge press dryer directly meets the sludge resource disposal standards.
The three benefits of deep dewatering of sludge summarized by the filter press manufacturer above, I believe you already understand why deep dewatering is necessary for sludge treatment. As the country pays more and more attention to sludge disposal, the advantages of sludge deep dewatering treatment will become more obvious, and filter press manufacturers have also expressed that deep sludge dewatering equipment is more popular.
