Sand

Sand is one of the most used materials as filtering medium for water filtration, both for water purification and wastewater treatment. The suspended particles containing the water are retained during their passage through the sand filter bed.
The sand supplied by KEIKEN is subjected to a process of washing, drying, and a classification, thus obtaining a precise particle distribution sand, suitable for use as a filtering medium.
With this process you can achieve different compositions and particle sizes completely controlled to meet the needs of each customer.
