Biwater AEWT designed, supplied and put six reverse osmosis desalination skids at Collier County’s reverse osmosis water treatment plant into operation. The skids are part of Collier County’s 12 MGD expansion project. 

Biwater AEWT was once again selected by the Poole and Kent company of Miami, Florida to carry out the work. The contract represents Biwater AEWT’s tenth major project with the same customer and  Biwater AEWT has delivered over 200 MGD of installed permeate capacity to this customer alone. 

Biwater’s modular design and the use of fiber reinforced plastic pressure vessel supports allowed the Poole and Kent company to fast track the project and enabled early water production which in turn  helped the city to meet their water demands during the worst year of drought on record to be experienced in the state of Florida.

The overall reverse osmosis water treatment plant design used a total of 2160 reverse osmosis low-pressure membrane elements housed in six 60 pressure vessel assemblies. 

The design uses a low pressure turbocharger to boost the second stage feed pressure and to balance the flux between the first and second stages. The use of the turbocharger also considerably lowered the required overall energy to produce the same amount of product water. 

The plant is designed as six identical stand alone operating trains which provide more operating flexibility.
