    Abstract: A reservoir of purified water is prepared from a natural body of water by constructing a prefiltering levee through the water to segregate the reservoir area from the remainder of the water body, pumping water from the reservoir area into the remainder, cleaning the floor of the reservoir area if necessary, installing a water purification unit in the reservoir, and then allowing the water to filter through the levee from the remainder of the water body into the reservoir for continuous further purification and recirculation by the installed unit. The water purification unit includes a mixing chamber, a filtering chamber, skimming means for intaking surface water into the mixing chamber, submerged inlets for intaking water into the mixing chamber from below the water''s surface, a pump for passing water from the mixing chamber through the filtering chamber, and outlet means for passing the filtered water directly back to the reservoir. The preferred skimming means comprises a mobile skimming gutter to insure a constant intake of surface water at various reservoir water levels and a submersible pump is preferably positioned in the mixing chamber to force the mixed water through one or more filter cells provided in the filtering chamber. The outlet means are preferably disposed to set up recirculation currents using the earth''s rotation effect, and means are also provided for backwashing the filter cells. To insure that the pump does not run dry the submerged inlet flow is preferably float modulated to provide the full capacity of the pump if the skimmed flow is temporarily reduced. Various purifying chemicals may be added to the processed water in its passage through the unit, and in a modified form of the invention, a portion of the purified water is passed back to the remainder of the water body for progressive purification thereof.

    Abstract translation: 在优选实施例中净化水体的方法，其中通过在水中通过构造预过滤堤从水体的其余部分分离储存区域，从天然水体制备净水的储存器，将水从 储存区进入剩余部分，如果需要清洁储存区域的地板，在储存器中安装水净化单元，然后允许水通过堤坝从剩余的水体过滤到储存器中，用于连续进一步净化 并由安装的单元循环。 水净化单元包括混合室，用于将表面水进入混合室的过滤室撇渣装置，用于从水面以下将水从混合室吸入混合室的淹没入口，用于使来自混合室的水通过 过滤室和用于将过滤的水直接返回到储存器的出口装置。 优选的撇取装置包括移动撇水槽，以确保在各种储存水位下恒定地吸入地表水，并且潜水泵优选地定位在混合室中，以迫使混合水通过设置在过滤室中的一个或多个过滤池。 出口装置优选地设置成使用地球+旋转效应建立再循环电流，并且还提供用于反洗过滤器单元的装置。 为了确保泵不运行干燥，浸入式入口流优选是浮动调制的，以便如果撇去的流被暂时减小，则提供泵的全部容量。 可以在加工水中通过单元加入各种净化剂，在本发明的改进形式中，将一部分净化水返回到水体的其余部分，以逐步净化。
