Type SL Double Medium Filter

Descriptions
Type SL double medium filter, which adopts two different mediums as filtrating medium to fully use their ability of interception dirt and control the particle size for different specific gravity and indexes under the suitable different medium gravities, material and sizes. The gradation of medium is approximate to the ideal distribution. The medium with bigger space among filtrating medium is on superior layer and the lesser is on the inferior layer, so the distribution is good for the best adsorption on whole layer. It increases the dirt arresting capacity, and also, has the dual perfect effect of removal oil and organic impurity in water.
This product, which is suitable to the treatment of oily wastewater and purification of water quality, has the advantages of impact in structure, complete in configuration, stable in operation, simple in handling, through in backwash, convenient in maintenance, etc.
