Abstract |
Swirl and helical bend devices were studied for three years at Lancaster, PA, and West Roxbury in Boston, MA. At Lancaster the study included: A full-scale swirl regulator/solids concentrator (SRC) for combined sewer overflow (CSO) control (24-ft (7.3-m) diameter) and a swirl degritter for SRC foul underflow (8-ft (2.4-m) diameter). At West Roxbury the study included: A pilot-scale SRC for separate urban stormwater treatment (10.5-ft (3.2-m) diameter) and a pilot-scale helical bend regulator/solids concentrator (HBRC) for separate urban stormwater treatment (60-ft (18.3-m) long). Data from the Lancaster facility indicated that the SRC is an efficient treatment device to remove heavier or 'first flush'-related suspended solids and grit. At West Roxbury, efficiencies were low for both units and appear to be related to very low settling velocities of the suspended solids. |
