Polishing of municipal secondary effluent using native microalgae consortia

Application of chlorine dioxide for secondary effluent polishing

There are still many difficulties for developing the projects of using treated effluents. In this study, the efficiency of chlorine deoxide in the process of preparing the effluent of Sahebgharanieh Plant of Tehran for reuse purposes has been determind. Major results are as follows: Total COD reductions resulted from effluent treatment by ClO2 solutions having concentrations equal to 1/4, 1/2 a...

Anaerobic Bioconversion of Heavy Hydrocarbons Using Native Consortia

Removal of nitrogen from wastewater using microalgae and microalgae–bacteria consortia

Exceeding nitrogen discharge into natural water bodies can lead to eutrophication in natural aquatic environments, as well as the decline in shellfish habitat and aquatic plant life. Currently, bacterial biological treatment process is the most common process employed in wastewater treatment plants, which requires extensive oxygen. The large demand for oxygen provided by mechanical aeration is ...

Economic Assessment of an Integrated Membrane System for Secondary Effluent Polishing for Unrestricted Reuse

Extra treatment stages are required to polish the secondary effluent for unrestricted reuse, primarily for agricultural irrigation. Improved technology for the removal of particles, turbidity, bacteria and cysts, without the use of disinfectants is based on MicroFiltration (MF) and UltraFiltration (UF) membrane technology and in series with Reverse Osmosis (RO) for dissolved solids removal. Fie...

Biological Conversion of Normal Chain Octadecane by Native Microbial Consortia

"> Long-chain alkanes are a major constituent of crude oils and their conversions into other compounds are of interest depending on the specific application. Here, five <span style="font-size: 9pt; color...
