Since ,industrial hydrogen peroxide, mainly contains hydroxide OH- and sodium ion Na+, the hydroxide can combine with many metal ions to form flocs or precipitates. For example, we all know that sewage contains metal ions such as aluminum ions (Al3+) or iron ions (Fe3+, Fe2+), strong acid salts and weak acid salts, which react with OH- ions to produce flocs or insoluble precipitation.

In this work, the ,catalytic gasification of sewage sludge, in supercritical water was investigated in a batch reactor (460 °C, 27 MPa, 6 min), and the separate and combined effects of the catalyst on the H2 production and phosphorus yield were investigated. The experimental results indicated that K2CO3 alone improved the H2 yield, gasification efficiency (GE), and carbon gasification ...

The ,sludge, volume is an indirect measure of the amount of suspended substances in the ,sludge,, and is used to describe the sedimentation properties of the ,sludge, in the sedimentation basin. Back in 1934 it was, however, realized that the use of an Imhoff cone was not entirely without problems, since the ,sludge, is excessively compressed in the tip of the cone, as well as having a tendency to ...
