Greensand Systems Design, Construction and Operation

Banner has designed and supervised the installation of many Greensand systems for multiple (12+) municipal clients. A total of 5 of these systems have been refurbished or rebuilt in the past 1 to 2 years. These systems are designed for the removal of iron, manganese and arsenic. Banner has developed its only proprietary green sand process interlock. This interlock system is particularly well suited to rural communities where the access to advanced PLC programming is not easily obtained, yet a high level of public health protection is still required. The system is simple and cost effective and uses highly reliable mechanical and pneumatic controllers, including mechanical fail safe valves for process faults and power and system failures. For larger sized plants, advanced PLC and system control can also be used and easily interfaced into a centralized control system
