Removing 磷 from your Wastewater

Whether it is a tried and true method of removing phosphorus or something a little more innovative – AquaPure experts can help you determine which process approach is best for your business.

On the cutting edge of treating waste water streams is rare earth elements. These provide a 1 to 1 atomic relationship with the phosphorus and also produce less sludge. Rare earth chemistry offers low dose rates, high removal capacity, with a friendly pH of 3-4 and a safe working environment.  另外, there are no equipment changes or capital expenditure costs associated with rare earth chemistry.

Phosphate By the Numbers:

100万+ – the anticipated dollar amount companies can expect to spend to remove phosphorus
893 – major treatment facilities with limits for phosphorus
30 – types of phosphorus species that can be present in your waste stream
27– the number of states currently regulating your waste stream
10 – the number of years until all 50 states will have phosphorous discharge limits in place
0.1 – mg/L total phosphorus that can be achieved with AquaPure chemistry

These are the numbers that concern manufacturers involved with pre-treatment, 阳极氧化, accelerated mass finishing and phosphate coatings.

案例研究: Helping an Anodizing Facility Meet Permit Limits

The Challenge

An 阳极氧化 facility was struggling to meet a pretreatment permit discharge limit of 10mg/L for Total 磷. If the facility could not retain pretreatment permit limits, they would be at risk for fines and potentially having their permit revoked.



The Hubbard-Hall team, called in by the facility owners to help solve the issue, began by evaluating different chemistries to determine which chemistry would meet discharge criteria consistently.
