The effect of direct reuse of filter backwash wastewater on treated water quality was studied by jar test.

The bioleaching of acidified sludge circumfluence treating tannery sludge;

Based on the analysis of the reason of sedimentation in dig-in basins,it is considered that sedimentation is brought primarily by circumfluence at the basin entrance and density flow.

The circumfluence is analyzed about its first appearing position and expanding direction.

Turbulence intensity measurements in the backflow region around a spur dike;

Study on the Impacts of Off-farm worker backflows in the export region——in-depth of interview of stakeholders in XINHUA and TAIJI town of Qianjiang district,Chongqing;

A new type steam distillation and reflux apparatus;

Dumb-bell ZnO with high purity and uniform size was synthesized by ultrasonic-assisted reflux method.

The titania fibers were prepared by a refluxing process using the above nano-TiO_2 powders as the materials immerging into the NaOH solution.

This paper presents a pilot experiment involving four plots of landfill with different structures for examining the leachate recirculation effectiveness of different conditions, i.

Landfill leachate recirculation technology can improve the leachate quality, i.

With the same inflow conditions,the anticlockwise recirculation regions predicated by Realizable k-ε model between adjacent ribs are larger than those obtained from the other two models.

Dynamic test of solder reflow process by microscope, CCD etal video picture, has been introduced.

There exists universally reflow in the entrance of excavated dock, which is similar to approach channel of low head hydro-junction located in alluvial river.

A new method using reflowing characteristic of photoresist to planarize PR(photoresist) is presented.
