GENERAL
1.0 General
A. The St. Johns River Water Management District is encouraging the use of
alternative sources of water to meet the water supply needs of the Central
Florida area. The City of Sanford has undertaken a beneficial and successful
project of reusing reclaimed water throughout the City to reduce the use of
valuable high quality groundwater supplies. The program has been so
successful that at certain times there is not an adequate supply of reclaimed
water to meet the demands of the system. As a result the City has pursued and
obtained a $300,000 grant from the St. Johns River Water Management District
to perform a full scale pilot test to determine the feasibility of using water from
Lake Monroe to supplement the City's reclaimed water supply and to implement
the first phase of the program, This will allow further expansion of the City's
Reclaimed Water System and further reduce, throughout north Seminole
County, the use of our high quality groundwater supplies protecting the resource
for future generations.
The purpose of this Amendment is to authorize the Engineer to provide the
following:
1. Preparation of documentation in support of obtaining grant funds from
SJRWMD District for the project.
2. Development and implementation of a pilot-plant study to determine
treatment requirements for the Lake Water to meet FDEP regulations.

The ZeeWeed~-based Dffnking Water process was developed by ZENON in order to reduce the
complexity and oost of treating feedwaters while providing enhanced tre=~tmerit quality. The
process is very tlexjble and reliable. For direst microfiltration application8, one slap treatrnent
is utilized comprised of a process tank and Irnmemed mGmbrar~e.
For applications requiting organice and color removal an additional. patent-pending protreatment
process is added upstream of the process tank for enhanced coagulation and tiocculation. This

Ruggedhess d Operation
ZeeWeedTM Systems achieve thfs high quality treatment In the presence of low or high solids
concentratbns
· w~hout clogging
w~zhout the need for frequent backweshroacl~puise cycles which stress membranes
· without any detrimental effects on the membrane flux
· without breakjng since ~t Is a composite membrane developed to structuraily and chemically
resist outside elements.
The use of enhanced O~ddation ie ~ontrolled by operator who can interTupt chemical use during
seasonal perlede when the organic content of the feed water is low which reduces sludge
proc~uction.
One Step Treatment
The ZeeWeed membrane is an immersed, outside-in membrane where the flow of wate~ is from
the outside of the membrane tO the Inside of the hollow fiber, meaning that the inside only sees
clean. microfiltered water. Solids, algae and days are filtered and remain outside and never
enter the membrane to cause fouling and plugging.
Ultra Low Energy
Being an imrT~ersed membrane ~lows for the operation of the ZeeWeed under a slight vacuum
!nstead of under pressure Eke other membranes on the manket. The ZeeWeed operates under a -
1 to -8 psi vacuum. This operational energy is very low and to our kslo~edge the lowest in the
membrane market.
Open Tank Free Space for High Solids Opera~on
The ZeeWeed membrane is framersad irkside the process tank, where solids and ether
compounds can float at ease without interfering wtth the operation of the membrane. This allows
the membrane to operate in high solids environments w~h the only limitation in eolids content

Modular Expand~blllty
The ZeeWeedTM membrane system can be expanded without 1he need for major footprint
expansion. A community adds only that capacr~y which meets the demand coming on line. As
such, .the expar~orl Is a small modular increment without the need of large footprint
infrastrlJcture.
These and other advantages make the ZeeWeed~-based DrinkJng Water prc>~eas a cos~
effective, high quality treatment option for peta~le water.
