With this advanced coagulant, wastewater treatment plants can achieve ultra-low phosphorus limits—as low as 0.07 mg/L—without the need to install or upgrade costly tertiary filtration systems. ClariPhos also produces far less sludge than alternatives and improves dewaterability, helping treatment plants significantly reduce costs for solids management.
ClariPhos has been successfully used in numerous wastewater systems including conventional activated sludge, membrane bioreactors, sequencing batch reactors, lagoon systems, rotating biological contactors, trickling filters, and more.
ClariPhos is made with the rare earth elements lanthanum and cerium, which have a very high affinity for phosphorus. These elements form a tight ionic bond with phosphorus to create rhabdophane, a dense and insoluble precipitate that settles up to two times faster than conventional Al- or Fe- based coagulants. The results are improved clarifier performance and reduced risk of carryover of suspended solids.
ClariPhos forms a tight preferential bond with phosphorus, which means far less coagulant is needed to achieve regulatory requirements—typically 30 to 70% dose reduction over alternatives. This lower dose rate results in significant reductions in sludge volume; as much as 34% less sludge than alum and 50% less sludge than ferric coagulants.
ClariPhos also helps improve sludge dewaterability over other coagulants, enabling up to 40% increase in attained solids.
Reports have estimated some wastewater plants may spend up to 40% of their operating budget on sludge management, so reduced sludge production and improved dewaterability can help significantly reduce sludge management costs.
ClariPhos is 100x less acidic than alum- or ferric-based coagulants and is typically dosed at a much lower rate. That means it is far less likely to lower pH of the wastewater system and require pH adjustment with alkaline chemicals.
Having a low freeze temperature (-40C) eliminates the need for heated storage and pipe heat tracing.
ClariPhos is safer to handle than alum- or ferric-based coagulants
Rare earth elements have low toxicity and arenot bioavailable to plants.
In most cases, plant operators can simply replace conventional alum or ferric coagulants with ClariPhos to easily and cost-effectively improve the chemical precipitation and settling of phosphorus. ClariPhos requires no special chemical feed equipment and will often work with existing feed pumps.
Bishop Water can provide comprehensive services for a trial and full-scale implementation of ClariPhos Rare Earth Coagulant. Our team will assess your plant’s current phosphorus removal equipment and operation to determine the optimal dosing location and dose rate for ClariPhos. Samples will also be obtained at various points in the treatment process to optimize ClariPhos performance through steady conditions as well as variable flows and loads.
Once ClariPhos is fully implemented, Bishop Water can provide ongoing support through routine technical service visits and ongoing sampling, analysis and optimization.
