The need to recycle water is a growing issue in
water-poor areas of the United States and around
the world. However, certain pathogens, such as
Cryptosporidium, can be present in recycled water and
pose a danger to human health. This article describes a
recent project that was conducted to explore efficient
ways to eliminate the threat posed by Cryptosporidium
in microfiltration residuals. After reviewing the various
methods to treat microfiltration residuals, the authors
focused their research on clarification for several reasons that include: clarification was
successful in treating spent filter backwash water
from conventional wastewater treatment plants;
clarification was economical; and, clarification was familiar to U.S. plant operators
and regulators. Includes 16 references, tables, figures.
