This is where desalination comes in. A firm appropriately called Poseidon Resources is nowclose to building the biggest desalination plant in America behind a power station by thebeach in Carlsbad. The power plant sucks in 304m gallons of seawater a day for cooling in anycase, so Poseidon plans to divert 104m gallons a day through its osmotic membranes.
海水淡化技术就因此出现了。恰如其名,Poseidon Resources公司将在美国修建最大的海水淡化厂,其厂址位于卡尔斯巴德的海滩附近的发电站后面。发电站每日总会吸取30400万加仑海水用于冷却,因此Poseidon计划每日用渗透膜淡化10400万加仑海水。
Fondling a pipe of membranes ,Poseidons Peter MacLaggan explains the scale: if water molecules were blown up to thesize of tennis balls, salt molecules would be softballs ,viruses would be trucks, and bacteria would be the size of power plants. From the 104mdaily gallons, 50m gallons of pure H2O will come out at one end and brine at the other, to befed back into the power stations discharge, and then into the ocean.
渗透膜如同卫生纸一样卷起来的,但却有大炮那么大。Poseidon的Peter MacLaggan一边摸着渗透膜一边解释道:如果水分子胀大到乒乓球大小,盐分子有垒球大,病毒有卡车那么大,细菌有发电厂那么大。在每天处理的 10400万加仑海水中,有5000万加仑的纯水从渗透膜一端流出,然后在其另一端变成浓盐水,最终由发电厂的排放系统流回海里。
