How ClariPhos rare earth coagulant helps keep pH in balance, while also achieving ultra-low phosphorus limits.
We’re not suggesting that you can use ClariPhos™ rare earth coagulant to control pH. But it’s unique properties mean that it is far less likely to lower the pH of the wastewater system and require the use of pH adjustment with caustic soda or other chemicals.
ClariPhos is a proven way to dramatically reduce phosphorus in treated effluent and achieve levels as low as 0.07 mg/L. This rare-earth technology outperforms conventional coagulants because it binds more tightly to phosphorus and forms a denser, heavier floc that settles more rapidly. By switching to ClariPhos, many treatment plants have avoided the need for costly equipment upgrades to meet stringent phosphorus limits.
ClariPhos is far less acidic than alternatives
ClariPhos has a median pH of 3.5, compared to ferric or alum coagulants that are typically in the pH range of 1.5 to 2.2. This means that these conventional coagulants can be up to 100 times more acidic than ClariPhos.
This dramatic difference in pH is compounded when we consider that the dose rate for ferric or alum coagulants is typically two to three times higher than that of ClariPhos, which can dramatically impact the overall pH of the wastewater system.
By replacing ferric or alum coagulants with ClariPhos, which offers lower acidity and dose rate, operators can maintain desired pH levels in the plant processes with little to no pH adjustment — translating to significant cost savings for chemical consumption and process control.
Less coagulant = less sludge
The low dose rate for ClariPhos, along with its high affinity to phosphorus, also results in far less sludge production. Lower sludge volumes mean less pumping, dewatering, hauling and disposal, which contributes to lower costs and additional savings for each of these operations.
