For instance, simplefiltration and disinfection of water at the household level dramatically improves the microbial quality of water, and reduces the risk of diarrhoeal disease at low cost.
例如，在家庭层次水的简单过滤和消毒可显著改善水的微生物质量和以低成本减少腹泻病的危险。

Thus, through simple means such as filtration (step 244), the leached lithium component can be easily separated from the insoluble transition metal component.
因而，经过简单方法如过滤（步 骤244），可以容易地将溶解出的锂元素与不溶性过渡金属元素分离。

The utility model has the advantages of high filtration accuracy, simple structure, low cost and dust resistance, which can be widely used on various vehicles.
