How RE300 Works

Problem:
Traditional metal salts are less efficient in meeting today’s ultra-low phosphorus levels.

Iron- and aluminum-based coagulants do not bind to phosphorus very efficiently or tightly.  They form intermediate metal hydroxides to which phosphate adsorbs to the surface. This is a function of surface chemistry instead of a strong ionic bonding. The ratio of Fe or Al to phosphorus can be 4 to 1, or even higher.  That is why it can take larger amounts of Fe/Al to reduce phosphorus to desired levels.

Solution:
RE300 is capable of achieving total phosphorus levels of .07 milligrams per liter or less.

RE300 preferentially reacts with phosphorus to form a strong crystalline ionic bond, creating an insoluble precipitate: REPO4·H2O (Rhabdophane).  RE300 achieves phosphorus removal at a 1:1 molar ratio of RE:PO4.  As a result, much less of the RE300 product is needed to obtain excellent phosphorus removal results as compared to iron- or aluminum-based coagulants.
