Discussion on the Existing Problems and Optimization Countermeasures of Sand Filter in a Southern Region
Through the field investigation of the waterworks in a southern region,due to the early construction age and long operating life of the minor waterworks,the sand filter has some problems,such as uneven distribution of filter particle size,high mud content,fast loss rate of filter material,poor backwashing effect and poor turbidity removal effect.In view of the above problems,the countermeasures of optimizing filter material gradation,optimizing backwashing parameters and equipment updating were put forward,which provided technical reference for the process optimization and transformation of the old waterworks.
