Quick filtration is an important and complex processwithin the conventional treatments of water purification,since it is the final physical barrier to retain particlesand control the microbiological risk. This study evaluatedthe influence of flow control on the filtration process of theclarified water of the Cauca River on the city of Cali –Colombia (Puerto Mallarino Water Treatment Plant) atpilot scale. Operation´s results of the pilot plant on adeclining rate condition were compared with the results ofthe previous operation at constant rate; the operationalcontrol variables of the filters were turbidity of the filteredwater and load loss. In general, the declining rate operationallowed a better performance of filters, resulting in a lowerturbidity in filtered water during the period of maximumefficiency and a better outcome of the load loss, behaviorthat is associated with a better distribution of solids on thefilter media, which allows to reduce the risk of transfer ofparticles through the filter.
