Characterisation and biodegradation of settleable organic matter for domestic wastewater

Transformation and characterisation of dissolved organic matter during the thermophilic aerobic biodegradation of faeces.

We conducted a comparison of the characteristics of dissolved organic matter (DOM) taken from the bio-toilet and other sources. A characterisation of DOM was carried out to assess the stability of the compost generated during the thermophilic and aerobic biodegradation of faeces. In addition, levels of soluble microbial products generated in the bio-toilet composting reactor were compared with ...

Characteristics of Effluent Organic Matter in Wastewater

Organic Compounds Fractionation for Domestic Wastewater Treatment Modeling

Organic compounds in domestic wastewater have a highly differentiated composition, which depends on the source of wastewater. Detailed fractionation of organic pollutants is indispensible to determine their transformation during treatment processes. Mathematical modeling requires the division of organic compounds in wastewater into the fractions: dissolved, suspended, biodegradable, and unbiode...

Hollow Fiber Membrane Bioreactor for COD Biodegradation of Tapioca Wastewater

The present work studied the application of membrane bioreactor (MBR) for tapioca wastewater processing that contained chemical oxygen demand (COD) ranging from 4000-9000 mg/L. A preliminary study was initially conducted in order to evaluate membrane performance with respect to its flux with MLSS concentration ranging from 4,500 to 10,500 mg/L. It was clear that fouling was observed during the ...

Characterisation and biological treatability of “Izmit industrial and domestic wastewater treatment plant” wastewaters

We investigated the conventional characterisation and biological treatability of wastewaters of the “Izmit Industrial and Domestic Wastewater Treatment Plant”. Respirometric procedures were carried out for the experimental assessment of organic contents of wastewater. The mean value of total COD was 1201 mg·l-1 and varied within a wide range of 580 to 1822 mg·l-1 for the 14 different influents....
