Whitepaper: Chemical-physical Water Treatment, Filtration and Flocculation
Introduction In water treatment plants chemical-physical processes play an essential part in the process chain. They are successfully employed in the pre- and post-treatment of waters of different origins, as well as of other process liquids. In this regard the removal of particles by filtration is a central step. Classical filtration processes are used for particles ranging from 1 μm to 100 ...

Replacing chlorine water treatment With Alstasan Silvox
Water Treatment, a chain of process carried out to purify water with different desired end results. These include physical as well as chemical means. Visible impurities can be removed through physical means like filtration, sedimentation and decantation but problem arises for invisible pathogenic organisms which can only be removed through chemical addition. Various advanced chemical technology ...

Microplastics penetrate all systems of the body, leading to behavioral changes
Summary New research by University of Rhode Island professor Jamie Ross focuses on the neurobehavioral effects and inflammatory responses of exposure to microplastics, as well as the accumulation of microplastics in tissues, including the brain. Her team found that the infiltration of microplastics in the body was as common as in the environment, leading to behavioral changes, especially in older ...
