Are you ready for a better coagulant for phosphorus removal?

3 simple steps to test rare-earth coagulant at your plant

New ClariPhos™ rare-earth coagulant is a proven solution to hit phosphorus levels as low as 0.07 mg/L in treated effluent and reduce sludge production by as much as 50% in the process.

Over 50 treatment plants in the US are already using it to comply with tough phosphorus discharge regulations, avoid the need to add tertiary filtration and reduce operating costs. 

Testing ClariPhos performance for your plant can be done easily, just by switching your current liquid ferric or alum coagulant to our rare-earth coagulant. 

The results will be visible almost immediately since ClariPhos binds more tightly to phosphorus. This produces a denser, heavier precipitate that settles about two times faster what you’re currently using. Your clarifier will perform better, you’ll achieve higher phosphorus reduction and produce significantly less sludge as an added benefit. 

Here’s how we’d do it:

1) Jar testing

Simple jar tests with ClariPhos and a small sample of wastewater can quickly demonstrate the effectiveness and anticipated performance of the coagulant at your plant. The results are also used to calculate the dose rate and verify that your current equipment is up to the task. We find that the dosage rates can be significantly lower for ClariPhos as compared to conventional coagulants, so a smaller, more precise feed pump may be needed. If your treatment plant does not currently have a phosphorus removal step, we can also help design and install the process and equipment. 

2) Plant assessment

A quick look at the plant’s treatment processes, configuration and performance will enable our wastewater specialist to verify process equipment and select the best feed point for ClariPhos to ensure optimum mixing and retention time. 

3) Installation

Replace your existing coagulant with ClariPhos and let the test begin. The duration depends on your plant and the conditions it faces. We recommend that the test go long enough to experience typical variations in flow and loading to collect a good data set.

Achieve phosphorus limits as low as 0.07 mg/L with ClariPhos rare earth coagulant

DATE POSTED: October 6, 2020

ClariPhos produces up to 50% less sludge than conventional alternatives

Hitting an ultra-low phosphorus limit for treated wastewater effluent can be difficult using ferric- or aluminum-based coagulants alone. Often, large amounts of these conventional coagulants must be used, yet treatment plants may still be unable to meet low phosphorus targets without the addition of costly tertiary filtration equipment.

But ClariPhos rare earth coagulant is enabling treatment plants to achieve phosphorus levels as low as 0.07 mg/L without filtration and without the need to use large amounts of coagulant. The rare earth elements in ClariPhos™, cerium and lanthanum, bind tightly to phosphorus and form a dense precipitate that readily settles out of solution within minutes.

Easily switch to ClariPhos
In most cases, plant operators can simply replace conventional 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. This simple switch can not only enable a plant to achieve regulatory compliance for phosphorus discharge, but it can also help communities to avoid spending millions for costly filtration equipment and ongoing operating costs.

Dozens of treatment plants are already using ClariPhos rare earth coagulant to meet stringent phosphorus targets and lower operating costs from reduced sludge production improved sludge dewatering and decreased sludge hauling and disposal costs.

Case Study:
In just one example, a 3.4 MGD municipal wastewater treatment plant tested Neo rare earth coagulant for its ability to meet a new final water quality effluent limit on phosphorus of 0.075 mg/L. The trial showed that the coagulant alone could consistently reduce phosphorus in the treated effluent to 0.036 mg/L.

This result was far superior to what the plant was able to achieve with its conventional coagulant, ferrous chloride, which could only reduce phosphorus to an average of 0.5 mg/L. After switching to Neo rare earth coagulant, the plant was also able to avoid installing new nutrient removal equipment, at an estimated cost of $2.8 million, and reduce solids production by about 35%.
