Key result
Balston filters and organic flocculation recover ~97% of enteroviruses from tap water.
Why the study?
The efficiency of virus recovery from different water types using a method enabling simultaneous concentration of four enteroviruses was investigated.
Population
Water samples from tap, natural waters, and Jerusalem wastewater spiked with four enteroviruses
Comparison
Concentration using Balston filters and organic flocculation based on selective antibody neutralization
Design
Experimental study assessing virus recovery efficiency

High recoveries (97% tap water) support method utility; leaves open standardization for wastewater surveillance.
Absolute Event Rate: 97% vs 68%
A method using Balston filters and organic flocculation effectively concentrates enteroviruses from various water sources, with highest recovery in tap and natural waters and lower recovery in wastewater.
Guttman-Bass et al. (1984) studied this question. Virus concentration using Balston filters and organic flocculation vs. Different water types (tap, natural, wastewater) was evaluated on Virus recovery efficiency. Virus concentration using Balston filters and organic flocculation achieved an average recovery efficiency of 97% in tap water and 68% in wastewater for four major enterovirus subgroups.
