ZENON Environmental has introduced a new reinforced hollow-fiber membrane system based on
its highly successful ZeeWeed 500 series of membrane. This system has been designed
specifically for large-scale drinking water and wastewater plants where moderate to high levels of
suspended solids are present in the water to be treated. The ZeeWeed system uses vacuum to
generate a differential pressure across the membrane. This allows the membrane to be used in a
very high solids environment in an open tank and achieve economies of scale that are not
available to pressurized systems.
This paper describes the main reasons why the new product was developed, the benefits it offers
the end user, and results from pilot and demonstration test work. Design examples explain how
the product is applied to actual projects currently under design in North America and
internationally. Guidance is given on how to design large drinking water treatment plants using
the new system. For example, methods of mixing, flocculation, two-stage membrane filtration
and residuals handling are recommended. Includes figures.
