Abstract: A water intake and pretreatment system (10) comprising an inlet for delivering water from a natural source to a reservoir (12); said inlet to reservoir having a net screen (16) to prevent entry of organisms above a predetermined size and including a one-way gate (30) to allow organisms to exit the reservoir; said reservoir further comprising a granular filter media for water and algae filtration; and a drainage layer for removal of filtered water from the granular filter media to a drainage outlet. A local backwashing apparatus (40) is included for localized backwashing of the granular filter media.

Abstract: Locally backwashing portions of filter media allows a simple and effective design of intake and pretreatment units, as well as their integration. An enclosure is used to limit portions of filter media and backwash them locally by suction, utilizing filtered water from adjacent filter media as the back wash water. Wastewater is produced at small amounts that allows efficient sludge treatment. This design enables water pretreatment at the intake unit, simplifying overall plant design and preventing damage to organisms living outside the intake unit.
Abstract translation: 过滤介质的局部反冲洗部分可以简单有效地设计进气和预处理单元以及它们的集成。 使用外壳来限制过滤介质的部分并通过抽吸局部反冲洗，利用来自相邻过滤介质的过滤水作为背洗水。 废水产生量少，可以有效地进行污泥处理。 这种设计使得进气单元能够进行预处理，简化了整个设备的设计，并且防止了对进气单元外部生物体的损害。
