Cyst Reduction in Water

This technical brief discusses the challenges posed by Cryptosporidium parvum and Giardia lamblia, protozoan contaminants in water. It explores their resistance to common disinfection methods and the need for effective removal, especially in municipal water systems.

Cryptosporidium parvum and Giardia lamblia are single-cell parasites commonly found in human and animal intestinal tracts. They exist as oocysts or spores and can contaminate water sources. These parasites are resistant to chlorine disinfection and pose challenges for water treatment systems. The Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) was established to address the need for additional public health protection against Cryptosporidium in water systems. Under LT2, systems must meet treatment requirements based on oocyte levels in source water. Filters play a crucial role in meeting these treatment requirements by removing oocysts. Graver Technologies QCR 1-micron filters are effective in removing these parasites from water sources.
