dilute sewage造句

• Heavy rains can overwhelm sewage treatment plants and allow partially treated or diluted sewage to enter waterways.
• Because British sewers are also expected to handle rainwater, a series of storm sewage overflows were provided, which resulted in diluted sewage being discharged into the River Don in times of heavy rainfall.
• High solids digesters also require correction of conventional performance calculations ( e . g . gas production, retention time, kinetics, etc . ) originally based on very dilute sewage digestion concepts, since larger fractions of the feedstock mass are potentially convertible to biogas.
• The cut-and-cover tunnel for the District Railway was built within the Embankment and roofed over to take the roadway . The embankment was faced with granite, and penstocks, designed to open at ebb tide to release diluted sewage when rainstorms flooded the system, were built into it as a means of preventing backups in the drainage system and of periodically flushing the mud banks.
