NUTRIENT REMOVAL UPDATE (2023)
- Starting from Bare Ground, Construct Large Scale P removal facility – 7500 GPM – including Innovative removal of the dissolved Phosphorus and processing of contained sediments from the lower water column
- Deliver a treated water Effluent of 55 ppb TP or less
- Secure and remove all treated particulate biomass
- Water Treated thru 3/31/2022 – approximately 2.7 Billion Gal
- TP Removal thru 3/31/2022 – approximately 10 Tons (3rd Party Verified)
- Annual Removal of 43,400 pounds of TP
- Annual Treatment of 2-3.5 Billion Gallons of Lake Water
- Annual Water column Sediments removed – 200 Million Pounds or 100,000 Tons
$115 per pound of removed TP is one of if not the lowest non-point source removal costs in the State. Comparative Projects such as STA’s range in the $325-$500 per pound, require large land areas, and have reduced effectiveness over time. Hybrid Projects and Water Farms range from $400 to $600 per pound.
In addition to the lowest cost per pound, the Lake Apopka project generates 81.6 Mitigation Credits each year with an approximate value of $8.16 Million against a Target annual cost of $5 Million. The result is a very favorable project that generates more environmental benefit than it costs.
North Lake Location TP Levels
- This location is the closest to the PFWS Effluent discharge pipe.
- Extremely low TP Levels in the range of 20 – 40 PPB.
- Combination of Efforts resulting in Historical Low TP Levels.
- Shad Harvest, Marsh Flow Way, PFWS and other efforts all contributed to this performance.
- Typical seasonal TP variations shown initially and less than 2 years later, historically low Phosphorus levels.
- The task now is to get the entire lake to these levels.

LIVE DEMONSTRATION (2019)
- Color was Reduced by 50% (Improves Submerged Aquatic Vegetation Habitat)
- Removed Total Phosphorus to 35 Parts Per Billion
- Dissolved Phosphorous to 20 Parts Per Billion
- Removed 70% of Background Iron
- Removed 30% of Nitrogen
The problem of excess nutrients, phosphorus and nitrogen specifically, in and around Lake Okeechobee is well documented and the resulting algae blooms featured almost nightly on the local and national news.
To demonstrate its proven solution, Phosphorus Free Water Solutions developed a Lake Okeechobee case study to showcase its technology that can remove nutrients before they can stimulate the explosive growth that results in large surface-covering blooms.
For 10 weeks, Phosphorus Free Water Solutions operated continuously, processing various waters coming into the lake, leaving the lake in both directions and in the lake itself.
With some slight variation among the treatment sites, Phosphorus Free Water Solutions demonstrated, 24 hours a day, 7 days a week, its capability to remove total phosphorus to approximately 35 parts per billion and dissolved phosphorus to 20 parts per billion, remove 70% of the background iron, reduce color by 50%, and remove 30% of the nitrogen. Coupling the demonstrated process with our biological nitrogen removal process improves the nitrogen removal to approximately 95%.
Removing nutrients to these low levels will initially reduce the frequency and intensity of algal blooms, and once deployed to enough locations, can help Lake Okeechobee reach a more balanced condition.

APOPKA
LIVE DEMONSTRATION (2019)
- Removed Total Phosphorus to about 30 parts per billion
- Removed Dissolved Phosphorus to 15 parts per billion
- First Technology to Demonstrate Removal of Dissolved Phosphorus
Lake Apopka is Florida’s second-largest lake after Lake Okeechobee. Decades of agricultural activities on the north shore of the lake, combined with waste water discharges, has rendered Lake Apopka highly impaired. Water column phosphorus reached as high as 200 parts per billion and, through diligent efforts by the St. Johns River Water Management District, has gradually been reduced.
During 2017, Phosphorus Free Water Solutions conducted a 90-day, 24/7 technology demonstration on the north shore of Lake Apopka. The purpose of this demonstration was to demonstrate the removal of the multiple forms of phosphorus.
As a direct result of PFWS’s successful demonstration and following a competitive process SJRWMD awarded PFWS a “first-of-kind” commercial scale, high-tech phosphorus removal project on Lake Apopka. This facility is under construction and expected to begin treating water in late January 2020.
Lake Apopka: Nuquatic’s Apopka facility, a 10 MGD treatment plant, has been operational since 2019. During this time, we have removed approximately 120,000 pounds or 60 Tons of phosphorus. The lake ecosystem has begun to respond with historically low phosphorus concentrations in this 42 sq mile lake.
Piney Point: Effectively treating water within 17 days of a State of Emergency at Florida’s Piney Point facility. All treated water met state and federal discharge requirements. Removed a total of 350 metric tons of phosphorus and 400 metric tons of nitrogen in less than one year.
