Dissolved air floatation is that air is dissolved under pressure is the liquid which is then released to atmospheric pressure in tube . as the microscopic air bubbles come out of solution in cell , they attach to the suspended solids in the surface in liquid , causing them to floatation th the surface , then solids are separated from liquid 气浮就是设法在待处理液体中通入或产生大量密集的带有压力的微细气泡,在管道以常压下释放,使其在池内与杂质,絮粒互相粘附形成整体浮体,从而依靠浮力使其上浮至液面,从完成固液分离的方法
" this new treatment works has been specifically designed to take advantage of the most advanced technologies , including clarification by dissolved air floatation units and removal of ammonia and manganese by primary aerated biological filters to produce high quality drinking water , " mr ko said . to conserve water , all wash - water used for regular cleaning of filters is recycled 他说,大埔滤水厂在设计上采用最先进的技术,包括以溶气浮选池进行澄清工作,以及使用初级曝气生物过滤池消除水中的氨气和锰,以提供优质的食水。
