New Biology

A number of new technologies for the advanced treatment of wastewater have recently been developed. The oxidative cometabolic transformation by methanotrophs and by nitrifiers represent new approaches in relation to organic carbon. The Biological Activated Carbon Oxidative Filters characterized by thin biofilms are also promising in that respect. Moreover, implementing genetically modified organisms with improved catabolic potential in advanced water treatment comes into perspective. For very refractory effluents chemical support techniques, like e.g. strong chemical oxidation, can be lined up with advanced biology.

Anaerobic Reactor

An expanded-bed anaerobic reactor with granular activated carbon (GAC) medium has been developed to treat wastewaters that contain a high concentration of inhibitory and/or refractory organic compounds as well as readily degradable organic compounds. The process is characterised by a combination of two removal mechanisms; adsorption on GAC and biological degradation by microorganisms grown on GAC. Applicability of the reactor to treatment of phenol, chloroacetaldehyde (CAA), pentachlorophenol (PCP) and tetrachloroethylene (PCE) was discussed based on experimental data. All chemicals focused on here were removed well and stably at a removal efficiency of more than 98% even during starting operation and shock load operation. Chemicals in influent that exceeded biological degradation capacity was initially adsorbed on GAC and then gradually degraded, and hence the adsorptive capacity of GAC was regenerated biologically. These results proved that a biological activated carbon anaerobic reactor was effective for treatment of wastewater containing hazardous chemicals, especially for strongly absorbable chemicals, as well as readily degradable organic compounds at high concentration.

Phenolic Wastewater

Treatment performance of COD in the presence of 2,4-dichlorophenol (2,4-DCP) was explored by using a biological activated carbon-sequencing batch reactor (BAC-SBR) system. Two COD levels of basic substrate were synthesized with a mixture of phenol and 2,4-dichlorophenol. Although effluent concentration was increased with reduction of sludge retention time (SRT) from 8-days to 3-days, treatment efficiency was indicated more than 90% of COD in all SRTs applied. Reactors operated with acclimated sludge could be expected to cope with quite high loading of inhibitory substances.
