Sludge treatment and disposal is more and more important
The next 10 years is the golden age of the sewage treatment market, will be built on thousands of sewage treatment plant. Each sewage treatment plant to discharge water content of about 99.2% of the excess of hundreds or even tens of thousands of tons of excess sludge, these huge amount of sludge will become the next urgent need to deal with the problem. Sludge treatment technology includes three aspects of sludge thickening, dewatering and drying. The existing basic is the sludge thickening and dewatering technology, after the sludge thickening and dewatering, the general water content can only be reduced to about 80%, while the developed countries are gradually reducing the water content of sludge to 20%-30%. Therefore, efficient and economical sludge treatment technologies including dewatering and drying technology will have a huge market.
With the improvement of sewage treatment rate, sludge production is also increasing, sludge treatment and disposal problems become more and more prominent.
