Ferthaul Florida RS

  • Performed free pilot on Lake Apopka in 2015
  • Suctioned water and muck directly from lake
  • Treated water with Mitton Cavitation
  • Had DEP testing completed on water
  • Performed 43 days of testing in winter 2015
  • Processed 8,500,000 gallons of canal water
  • Removed over 3 tones of Phosphorous

What is Cavitation?

  • the formation of an empty space

within a solid object or body

  • the formation of bubbles in a liquid,

typically by the movement of a propeller through it

Why Cavitation

The extreme conditions of cavitation can break down pollutants and organic molecules Collapse of cavities generates hydoxyl ions, which are useful in realizing many benefits in effluent treatment

Action Plan

Take advantage of Reduce/Reuse/Recycle Allow nature to re‐balance Remove Phosphorus – Don’t spread it around

slide-7
SLIDE 7

Reduce – Reuse ‐ Recycle

  • Reduce P and N through

reduction of agriculture use

  • Reuse the P and N for

agriculture

  • Recycle the water back to

the lake

slide-8
SLIDE 8

Process the Lower layer of Lake

  • Remove the lower layer with the

highest content, said to range from 3 to over 17 feet thick

  • Separate using Parabolic screens

and treat with Cavitation

  • Return the water to the lake with

levels under 0.07

  • Re‐purpose the slurry with P and

N for other agriculture

2015 Pilot

  • Barge with pump to suction influent from lake
  • Pumped to two 2500 gal holding tanks
  • Processed by Mitton Cavitation Valve
  • Returned to 2500 gal Tank
  • Decanted to second 2500 gal tank
  • Tested from top of second tank

Success!

“Based on comparing the analytical chemistry sample results for the incoming dredge material (influent) and post‐process water (effluent), the pilot plant removed total phosphorus from 8.0 mg P/L in the influent sample to 0.25 mg P/L in the effluent sample. Similarly, total nitrogen was reduced from 150 mg N/L to approximately 4.4 mg N/L.” “The Department finds the results from this pilot project successful in reducing total phosphorus and total nitrogen.”

What to do with the Slurry?

slide-25
SLIDE 25

Reuse of the Effluent

  • Test cells on SJRWMD land close to canal
  • Slurry applied to 4 cells

– 1cell seeded with grass seed – 2 cells with thin layer applied – 1 cell with think layer

  • 2 cells left as control cells
