This seems to be a mates deal at the Byron Bay sewage treatment plant. All STP's use alum to remove phosphorus, the sewage is passed through an alum wash. So of course Viro would remove phosphorus since it is alum. Doesn't seem to prove anything. No-one is going to buy Viro to remove phosphorus because they are already set up with alum washes and alum is cheaper than Viro
