The SAND quartzite filters are used to reduce water turbidity (clarifying process) silt, clay, sand and colloidal substances.
The impurities accumulated by the filter masses are periodically removed with a counter-current washing.
The counter-current washing frequency can be programmed in time mode (Models SAND ATL - ATM time based) or based on the volume of treated water (SAND AVL – AVM volume based). The system size and models vary based on requested capacity and the turbidity present in the water to be filtered.
The SAND water clarification devices are supplied with accessories that make installation easier and are certified at the international level for quality and safety
