The Big Brand Water Filter Skid Mount Commecial Reverse Osmosis system is a turn key system that is pre-asembled and ready for operation. Depending upon the application you may want to add an ozone system to the storage tank and/or uv disinfection. This system can be used for car washes, coffee houses, restaurants, or any other application requiring high quality low TDS water. We do include a TDS blending valve for those wishing to use this for whole house reverse osmosis. If the water is too pure it can leach copper pipes. The TDS blending valve allows you to add back some TDS to prevent leaching. pH correction can be added for an additional charge. Available in 1800 gpd to 10,800 gpd configurations
