Abstract |
Full-scale, municipal, slow, sand filters at seven sites in the Syracuse, NY, area were monitored before, during, and after filter scraping to verify the presence or absence of a ripening period to determine the filter run length and to quantify the labor and material required for scraping and resanding operations. Results showed some evidence of a ripening period, ranging from 6 hr to 2 wk, in 4 of the 10 operations monitored. The factor that seemed to have the most significant effect on the quality of the filtrate was the amount and nature of the particulate matter present in the raw water. |
