Considerations on the design and financial feasibility of full-scale membrane bioreactors for municipal applications
Based on the practical experience in design and operation of three full-scale membrane bioreactors (MBR) for municipal wastewater treatment that were commissioned since 1999, an overview on the different design concepts that were applied to the three MBR plants is given. The investment costs and the energy consumption of the MBRs and conventional activated sludge (CAS) plants (with and without ...

Preliminary and Primary Treatment of Wastewater (or Sewage)
is the first of the three distinct steps involved in traditional sewage treatment plants. Primary wastewater treatment is the first of three treatment phases that follow pre-treatment. In fact, the wastewater treatment process consists of three phases: primary treatment, secondary treatment and tertiary treatment. Here’s a quick look at sewage primary treatment process ...

Design principles to achieve a robust sewage treatment process using rotating biological contactors and reed beds
Severn Trent Water Ltd. has chosen to adopt rotating biological contactors (RBCs) and reed beds amongst other technologies for treating sewage where the population is less than 2000. The design of an RBC to achieve a fully compliant effluent can be difficult when flows are small or the system is combined and an overflow is not permissible. In addition, RBCs have been plagued by mechanical ...

Tertiary treatment for wastewater reuse based on the
Daphnia magna filtration – comparison with conventional tertiary treatmentsTertiary treatments are required to permit safe reuse of wastewater. The performance of a new biological tertiary treatment based on the filtration by a population of Daphnia magna was studied and compared with the performance of other conventional tertiary treatments such as coagulation-flocculation, settling tank, disc filtration, sand filtering and ultraviolet (UV) light. The analysis was ...

Identification of pathogen bacteria and protozoa in treated urban wastewaters discharged in the Ebro River (Spain): water reuse possibilities
The aim of this research work is to identify the presence of pathogens, bacteria and protozoa, in different treated urban wastewaters and to relate biological pollution with the processes used in wastewater treatment plants. A study of the possibilities for water reuse is carried out taking into account bacterial and parasite composition. The analysed bacteria and protozoa are: Enterococcus ...

Irrigation by Sewage Effluents in Yemen
Yemen is the least advanced country among Middle East Countries in the sewage reuse and safety control. The current sewage effluent quality in Yemen is generally poor as none of the existing sewage treatment plants produces effluents comply with the effluent quality regulations. The oxidation and stabilization ponds are considered the most appropriate for the warm climate conditions in the ...

Adsorption characteristics of ammonium exchange by zeolite and the optimal application in the tertiary treatment of coking wastewater using response surface methodology
Natural zeolite is a favorable NH4+-ion exchanger in the tertiary wastewater treatment. In this study, a natural Chinese zeolite was anatomized using the mercury injection method, X-ray diffraction, and scanning electron micrographs. The kinetic process of ammonium adsorption onto the zeolite was best described by the pseudo second order model; the adsorption equilibrium data fitted ...

Urban wastewater reuse: a pilot plant experience
The results of a preliminary verification of domestic wastewater reusability in L'Aquila (Italy) are reported. A Tertiary Treatment Pilot Plant (TTPP), rotary filtration and Ultraviolet (UV) Radiation disinfection, was added to an Urban WasteWater Treatment Plant (UWWTP) to test the compliance with water quality indicated for reuse by the enforced Italian regulation. The TTPP was managed varying ...

Microbial reduction in wastewater treatment using Fe3+ and Al3+ coagulants and PAA disinfectant
Wastewater is an important source of pathogenic enteric microorganisms in surface water and a major contaminating agent of drinking water. Although primary and secondary wastewater treatments reduce the numbers of microorganisms in wastewater, significant numbers of microbes can still be present in the effluent. The aim of this study was to test the feasibility of tertiary treatment for ...

Emergent contaminants in the wastewater effluents of two highly populated tropical cities
Exposure to the anthropogenic chemicals known as endocrine disrupting compounds (EDCs) may result in negative biological effects. Low levels of EDCs in the environment aggravate the problem as exposure is constant. Urban areas concentrate pollution as greater volumes are released from human activities. Water for public supply is particularly vulnerable as the sewage treatment facilities may ...

Operation of an integrated algae pond system for the treatment of municipal sewage: a South African case study
Integrated algae pond systems (IAPS) combine the use of anaerobic and aerobic bioprocesses to effect sewage treatment. In the present work, the performance of IAPS was evaluated to determine the efficiency of this technology for treatment of municipal sewage under South African conditions. Composite samples were analysed over an 8 month period before and after tertiary treatment. ...
