  • Southeast Georgia sewage treatment

    Problem: A WWTP in Southeast Georgia located on a resort island has a 3 million gallon per day flow. The WWTP was experiencing major odor problems at the head of the plant, as well as poor digestion and settling of bio-solids in the SBR’s and aerobic digesters. The odors were primarily H2S and were the source of numerous complaints from the residents living in the vicinity of the WWTP. The plant ...

  • Study on sewage sludge gasification

    Aimed at creating new technology to reduct greenhouse gas emission, the Tokyo Bureau of Sewerage has developed a system generating electricity with a gas engine using biogas generated by pyrolytic gasification of sewage sludge in a fluidized-bed gasifier. A 15t/d demonstration facility was built based on a dehydrated sludge and demonstration tests were run for 3400 hours from 2005. As a result of ...

  • An alternative to biological treatment for sewage

    Most sea-side towns discharge sewage into the sea, normally some distance off-shore, via an extended out-fall sewer. A town of 100,000 population will produce more than 14,000 cubic metres (3,000,000 gallons) of sewage every day of the year. No small problem. In some coastal locations the sewage used to receive only basic, simple treatment, usually  "screening" to remove any large ...

  • Recovery of Phosphorus from Sewage Sludge

    In the following, a method to recover phosphorus from sewage sludge as MAP (magnesiumammonium- phosphate, also called struvite) is to be presented. The process uses sulfuric acid to leach phosphorus out of digested sewage sludge. After solid-/liquid-separation, interfering metal ions in the liquid phase are inactivated through complexation. For the subsequent precipitation of the phosphorus, ...
