Pyrobustor - A Proven,Small-Scale, Biosolids-to-Energy Solution
27 municipalities in southern Germany set up a special-purpose entity called KSV GmbH for the specific purpose of disposing regional sewage sludge. The goals of this project were two-fold; eliminate the expensive cost of transporting sewage sludge over long distances and avoid incalculable costs by outsourcing sludge disposal. To achieve this, KSV GmbH installed the Pyrobustor® at the ...

Relationship between sludge moisture content and disposal strategies
1.Moisture content and sludge properties: Sludge is mainly composed of dry solids (s) and moisture (w). The moisture content refers to W/(S+W), which is the mass ratio. According to the definition, a simple calculation can be concluded: the decrease of sludge moisture content can effectively reduce the mass and volume of sludge, and the higher the moisture content, the more obvious the effect. ...

The way to solve the sludge problem
The sludge after urban domestic sewage treatment generally has a moisture content of about 80%, is rich in nutrients such as organic matter, and contains a certain amount of heavy metals and harmful substances such as viruses, pathogens, and parasite eggs. Improper disposal of sludge will cause serious secondary problems. secondary environmental pollution. At present, there are three main methods ...

A 600T/D sludge thermal drying project case from Chongqing in China
It is proposed to build a sludge thermal drying plant in the reserved land for a power plant in Chongqing. The project construction is divided into three phases. The scale of the first phase is 600 t/d (moisture content 80%). Considering the fluctuation range of sludge moisture content (75%-82%), the maximum solid flux of treatment is 150 t DS/d. 1.Sludge components Table 1 shows the average mud ...

How to Turn Sludge into Clean Electricity
Step 1: The sludge dryer is used to reduce the moisture content from 80% to 30%, so that it can be better sent to the boiler for mixing. Step 2: The dried sludge is fed into the pot through a fully enclosed conveyor belt. Step 3: Scientifically and environmentally treat the odor, pollutants, ash, waste gas, etc. generated in the process of "sludge conversion to electricity" to ensure that no ...
