The use of chitosan, an abundant natural polysaccharide, as a coagulant aid is significant not only for safe water treatment but also for the effective utilization of unused natural water resources, which are mostly wasted. We experimentally determined the optimal treatment conditions for us...
aThis implies that a nation can buy retirement income with a funded pension system at a lower long-run cost than with a pay-as-you-go system, i.e., the savings deposits in a funded system are less than the tax required in a PAYGO system to provide the same level of benefits. 这暗...

Water Treatment Coagulants Coagulant water treatment chemicals come in two main types - primary water treatment coagulants and coagulant aids. Primary coagulants neutralize the electrical charges of particles in the water which causes the particles to cl
This study focuses on the effect of rapid mixing on the coagulation efficiency in a full-scale drinking-water treatment plant and discusses the mechanisms involved in the floc-formation process. The results refer to three periods of operation of the waterworks when no mechanical mixing was provided...
Impact of ozonation and biologically enhanced activated carbon filtration on the composition of micropollutants in drinking water.
