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.
Historically there have been 3 ways to treat phosphorus in waste streams: Iron and aluminum based compounds for precipitation. While they can be cost effective methods, they also require high doses because the level of molecular connectivity is low. In addition, they produce large quantities of sludge which is difficult and expensive to dispose of. The third way is bioaugmentation which reduces sludge. Specific training is needed to run the equipment for this treatment method.
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. Additionally, there is no capital expenditure costs associated with rare earth chemistry.
