Retrofit of conventional multi-media filters
The ZeeWeedŽ membrane is the most efficient system available on the
market for upgrading filtration plants. By simply replacing existing
media with ZeeWeedŽ membranes, conventional filtration plants can be
converted into state-of-the-art ultrafiltration facilities. ZeeWeedŽ
membranes have been designed to fit in virtually any filtration bed
and can increase capacity in the same footprint. As for compliance,
ZeeWeedŽ ultrafiltration membrances produce water that exceeds regulatory
standards.
Features and Benefits
Proven UF physical barrier technology
» Provides superior
public health protection and regulatory compliance
Dramatically increase plant capacity in the same footprint
» Reduces capital costs
by minimizing land acquisition and construction costs
Most flexible membrane module and cassette design
» Lowers capital costs
by reusing more of the existing infrastructure
» Retrofit existing
tanks of different sizes and depths
Simple operation and maintenance
» Minimizes operating
costs through greater automation and less chemical use

Retrofit with advanced treatment technology,
rebuild, or expand with current technology? Those are the choices
that many growing municipalities face as rising water demands
and increasingly stringent water regulations compel water managers
to boost capacity and quality at their water treatment plants.
Making the right decision involves a careful evaluation based
on many factors such as construction costs, current and future
regulatory requirements, future demand, and projected operational
costs, just to name a few.
For the Columbine Water Treatment Plant (WTP), a large 30-million
gallon per day (MGD) dual-media gravity filtration facility
in the City of Thornton, Colorado, retrofitting the existing
filter basins with advanced ultrafiltration (UF) membranes was
the best way to meet the fiscal, technical, and performance
requirements for the 30-year old facility.

The City of Greater Sudbury with a population of 165,000 takes great
pride in its commitment to enhancing and sustaining a healthy environment
for residents and tourists. With over 200 fresh water lakes within its
boundaries, the city is a fisherman's outdoor paradise.
The City of Greater Sudbury decided to work with CH2M Hill to retrofit
and upgrade the existing plant. After extensive piloting, Sudbury selected
ZENON in January 2002 to provide the patented ZeeWeedŽ technology. The
new upgrade will also include a new reservoir, new pumping station,
ultraviolet (UV) disinfection system and relocation of underground water
mains.

The Draper Irrigation Company needed to examine how to increase capacity
and improve water quality at its WaterPro Water Treatment Plant (WTP)
in Draper, Utah, without increasing the foot print of the WTP.
Despite budget levels that were set for conventional treatment alternatives,
the company continued to strongly consider membranes because of their
ability to produce high quality water in a very compact plant layout
and for consistent reduction of high turbidity spikes under virtually
all conditions.
