| DESCRIPTION: Design, procurement, construction,
installation, start-up, operator training, and on-going monitoring
of two pilot scale 300 mm diameter slow sand filters, each capable
of handling flows up to 500 L/day. The objective is to determine
maximum sustainable through put, fouling propensity, filter life
(scraping frequency) and removal efficiency under variable raw
water quality from a surface water source that exhibits considerable
seasonal variation in water quality. |
