摘要： An apparatus for removing impurities from water and/or wastewater and a method of installing a fluid distribution system in the apparatus. In the most preferred form of the invention, the fluid distribution system is an air scour system for directing air through the filter bed to assist in cleaning of the filter bed to remove impurities trapped in the filter bed during a service run. In the most preferred form, the method of installing the fluid distribution system in the filter bed is performed by imparting a force to the filter bed to permit the fluid distribution system to be installed in the filter bed without removing media. The fluid distribution system is preferably configured to permit the fluid distribution system to be readily installed in the filter bed and at an optimum orientation.

摘要： 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.

摘要： A water treatment system, method and apparatus for removing sediment, chemical pollutants and debris from contaminated stormwater runoff using physical, chemical and biological processes by passing runoff water preferably through a two-stage filtering and treatment system. The apparatus includes a first stage chamber filter system comprising a water storage area, a mulch layer a soil mixture of aggregate, organic material, soil, and live woody and/or herbaceous plants. The second stage treatment system is a water-filled lower chamber with baffles to increase the flow path of treated runoff through the chamber. Contaminated stormwater runoff or wastewater effluent is directed to and passes through the first stage chamber by gravity where the contaminated water is filtered and treated by the mulch, soil and plant filter media under aerobic conditions. The treated water from the first stage is directed to the second stage water-filled chamber where it is further treated through physical means (sedimentation) and anaerobic biological processes and discharged to the receiving waters or drainage system. The first stage chamber can be used without the second stage chamber when conditions warrant.

摘要： The invention relates to a method and an apparatus for cleaning the sand beds of slow sand filters, infiltration basins and pools of other types having sand beds in water treatment works and similar plants, while the filter is in service, by removing a few centimeters of the bed surface, cleaning the sand of the sludge or filter film formed on the bed surface, returning the cleaned sand to the bed, and discharging the separated sludge, suspended in water to drain or to a suitable disposal site. This is achieved using a tracked cleaning machine equipped with a submersible pump (7) and nozzle (8) to remove the top layer of sludge-bearing sand from the bed, cleaning the sludge from the sand thus removed in a hydrocyclone (13), returning the cleaned sand to the bed via a spreader plate (15) and discharging the water-suspended sludge to a drain or to a suitable disposal site through a hose (17).
摘要翻译：本发明涉及一种在过滤器使用中清洗慢砂过滤器，渗透池和其他类型的沙床的沙床的方法和装置，其中在过滤器处于使用状态，通过去除几厘米的在床面上清洗形成在床面上的污泥或过滤膜的沙子，将净化的砂子返回到床上，并将分离的污泥排出，悬浮在水中排出或排入合适的处置场所。这是使用装有潜水泵（7）和喷嘴（8）的跟踪清洁机器来实现的，以从床上去除含污泥的砂的顶层，在水力旋流器（13）中清除由此去除的砂子上的污泥，通过扩张板（15）将清洁的砂子返回到床中，并通过软管（17）将水悬浮的污泥排放到排水口或适当的处理场所。

摘要： The invention relates to an apparatus for cleaning a slow sand filter for a body of liquid while the liquid is in situ, in which there is a carrier adapted to traverse the body of liquid, and a device carried by the carrier and adapted to skim successive layers of sand from the filter. The carrier is a floatable vessel and the skimmer device is an auger. The skimmer device is controlled by depth control means which are automatically adjusted in response to the contour of the filter.
