  • PeCOD® Case Study: 15 Sewer Use By-Law Monitoring: Batch Release Tracing City of Austin, Texas

    Municipal wastewater treatment plants are designed to process a calculated range of organic loading in the raw influent. The calculation of this loading is based on characteristics of the plant’s region, such as population and industry type. Organic loading is most often quantified by the concentration of parameters such as Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), ...

  • Greywater characterization and handling practices among urban households in Ghana: the case of three communities in Kumasi Metropolis

    Greywater management in Ghana receives little or no attention although untreated greywater is associated with environmental and public health risks. This paper assesses greywater characteristics and handling practices among urban households in three selected communities in Kumasi, the second largest city of Ghana. The study involved in-depth surveys (interviews and observations) with 90 ...

  • New dimensiong guideline and standard for the activated sludge process

    Since June 2016 a new standard for the design of activated sludge systems is valid. The most significant point is the change of the basic value from BOD to COD. The standard is also the basis for designing SBR-systems. The article discusses main aspects of the new design basis and how AQUA DESIGNER has been modified and adapted to this. In AQUA DESIGNER you can calculate the continuous and ...

  • The rehabilitation of 43 year old waste lagoons

    In 1967 the City of Concordia, MO built a segmented lagoon system to handle the small town’s waste requirements. The main industry in Concordia is a Tyson renderings plant, and the lagoon system was designed to also handle that plant’s final waste and water polishing requirements. The lagoon system was a relatively standard design, consisting of an 18.7 acre primary lagoon, a 5.6 acre ...

  • Potential of integrated vertical and horizontal flow constructed wetland with native plants for sewage treatment under different hydraulic loading rates

    In this study, a pilot-scale integrated constructed wetland with vertical flow (VF) and horizontal flow (HF) in series was designed and investigated to evaluate sewage wastewater treatment capacity. The VF unit was planted with Canna indica and was 1.2 m long, 1.2 m wide, and 1.2 m high; whereas the HF unit contained Colocasia esculenta and was 3.0 m long, 1.0 m wide, and 1.0 ...
