Performance evaluation of wastewater stabilization ponds in Yazd-Iran
Background: Yazd waste stabilization pond facilities consist of three stabilization pond systems, module 1, module 2 and module 3 that AWSP module 1 has started its operation. The existing facilities have had several problems in their operation. The objectives of this research were to evaluate the performance of stabilization ponds in wastewater treatment of the city of Yazd, due to several pro...
متن کاملA Novel Potassium Channel in Photosynthetic Cyanobacteria
Elucidation of the structure-function relationship of a small number of prokaryotic ion channels characterized so far greatly contributed to our knowledge on basic mechanisms of ion conduction. We identified a new potassium channel (SynK) in the genome of the cyanobacterium Synechocystis sp. PCC6803, a photosynthetic model organism. SynK, when expressed in a K(+)-uptake-system deficient E. coli...
متن کاملEpipelic cyanobacteria and algae: a case study from Czech ponds
The present paper focuses on the epipelic cyanobacteria and algae (particularly desmids). Altogether 45 sediment samples were taken at ponds covering a pH/conductivity and trophic gradients. Statistic evaluation based on environmental variables measured, divided localities into four major groups differing also by sediment quality and its algal flora. Altogether 39 cyanobacterial species were fo...
متن کاملNitrogen fixation and photosynthetic oxygen evolution in cyanobacteria.
The biological reduction of N(2) is catalyzed by nitrogenase, which is irreversibly inhibited by molecular oxygen. Cyanobacteria are the only diazotrophs (nitrogen-fixing organisms) that produce oxygen as a by-product of the photosynthetic process, and which must negotiate the inevitable presence of molecular oxygen with an essentially anaerobic enzyme. In this review, we present an analysis of...
متن کاملCotreatment of sewage and septage in waste stabilization ponds.
A one year study was carried out in a waste stabilization ponds system where septage and sewage are cotreated. The system consists of two septage ponds which operate alternately followed by two ponds in series which receive the combined effluent. The septage ponds also act as evaporation ponds for the accumulated sludge. The monitoring program was divided in two phases. The results of the first...
