sedimentation

The sedimentation analysis method was used for measuring the sand content of settleable solid in wastewater.

The total sedimentation was that rivers were branching and migrating frequently,and the sedimentary structures and fossil of ichnite were growing generally.

Two percent of HPMC appeared to be a satisfying suspending agent by evaluating the sedimentation rate and the redispersion of racecadotril.

Two percent of HPMC appeared to be a satisfying suspending agent by evaluating the sedimentation rate and the redispersion of Nabumetone.

Re-sults The sedimentation rate and viscosity of CMC-Na were the best，the redispersibility of AlCl3was the best.

This paper introduces the application &the problems of LW - 380B sedimentation centrifuger in PVDC resin dewatering and the renovations to the centrifuger.

The study indicates that either sedimentation by adding sulphide and polyferric sulphate or ferrooxidant method has sim ple operation process, perfect effects and extensive application prospects.

Dissolution is controlled by both sedimentation and tectonization, and the converted degree on reservoirs is closely related to sedimentary facies and the distance from unconformity interfaces.

Site soils in southern area of Jiangsu province belong to washland sediment or limnetic facies sediment.The components of sediment are very complex and process of sedimentation is in disorder.
