The world's first thermal drying technology for sludge treatment is the UK's Bradford company.
In 1910, the company was the first to develop rotating kiln type sludge drying sludge dryermachine and its application in sludge drying practice;
1915 this technology has been HuMersfield adopted; a few years later, America also developed a similar sludge drying machinery.
By 1930s, the flash dryer.

To twentieth Century sixty or seventy years, the sludge thermal drying technology has been gradually improved.
The end of the 1980s in the 20th century, because of the sludge in the landfill, cast into the sea, agricultural various restrictive conditions and unfavorable factors of the highlight, also due to the technology in Sweden and other countries some sewage treatment plant.
The successful application, the sludge drying technology in Western industrialized countries quickly spread.
Such as the European Union at the beginning of the eighties of the 20th century only several sewage treatment plant sludge treatment by thermal sludge drying equipment, but to the end of 1994 has 110 heat drying of sludge treatment plant, and is expected in the next few years, heat drying of sludge treatment plant will be added to the current more than 10 times.
