Backwash Characteristics
Load the Aldex CR 9 MP resin in the pressure vessel. Then, backwash the resin bed at a rate that expands the bed 50 to 75 percent to remove any foreign matter, air pockets and reclassify the bed. Aldex CR 9 MP is backwashed ONLY ONCE—after the initial loading and prior to start-up.
When the bed has settled, it is ready to begin operating on a continuous flow or intermittent basis. There are no regenerant chemicals to purchase and store and no waste stream generated requiring neutralization or haulage.
