Wastewater-based epidemiology and monitoring of the SARS-CoV-2 virus have been presented as a promising tool for health officials and researchers to predict outbreaks and provide additional surveillance data, contributing to community-level screening and prevention efforts. Among all the challenges, the most urgent one is the wastewater concentration and virus detection of relatively low viral particle loadings in large volumes of wastewater. Therefore, the sampling design, including the sample concentration, is a crucial step for detecting RNA of SARS-CoV-2 in municipal wastewater. Classical wastewater concentration by centrifugation is time-consuming therefore, the design of concentration devices using an ultrafiltration membrane system could pave a faster way for rapid, effective, and low-cost sample analysis. The main objective of this study was to investigate the performance of the wastewater concentration device designed by Riga Technical University and analyze the recovery rate for the ultrafiltration membrane system. For this purpose, the virus spiking method was used to investigate the recovery rate of the concentration device and optimize the methodology for accurate sample preparation for the concentration.
