The invention relates to a filter table preferably for sand filter plants constructed in concrete for utility water and waste water purification. The filter table is composed of a filter plate and support apparatuses. The filter plate serves as a base plate for supporting the filter masses and is provided with nozzles for discharging the filtrate and for backwashing the filter masses with water and/or air. The filter plate is supported on support apparatuses which must absorb both vertical forces from the filtration process and forces in the opposite direction from the backwashing. According to the invention, the filter plate and the support apparatuses are manufactured as a monolithic component and anchored in the filter tank. The structural configuration of the filter nozzles and of the seals are further subject matter of the application. |
