The influence of the addition poultry manure on thermophilic acid co-fermentation sewage sludge and wine vinasse was studied. For this, discontinuous tests were carried out to determine potential for hydrogen production (BHP tests) 50:50 mixtures with different amounts (10 g/L, 20 g/L 30 g/L). performance determined under tested conditions. experimental results revealed values TCOD SCOD, TS VS,...

Excess sludge treatment is indispensable in sewage plants. This study aims to reduce the excess material from activated and establish a mathematical model. Sludge dissolution rates were calculated by measuring total chemical oxygen demand (TCOD) soluble COD (SCOD) with regard water quality before after pretreatment. Then, reduction effects obtained means of suspended solid (SS) changes. The maj...

Nutrient availability plays a crucial role in microalgae growth domestic wastewater. In this study, we investigated the impact of different nitrogen and phosphorus ratios (5:1, 10:1, 20:1, m∙m−1), addition inorganic carbon on nutrient uptake from Microalgae biomass achieved values ranging 0.54 to 1.41 g·L−1. The cultivation process had maximum removal efficiencies 83.7% for soluble chemical oxy...

Microwave irradiation is a promising pre-treatment method for sludge stabilisation, but there are few studies focusing its effect on organic matter solubility and biodegradability of wastewater originated from the food industry. In our research, microwave was applied standalone in combination with alkaline treatment to enhance solubilisation biodegradation content meat industry municipal sludge...

In this research, the continuously operated laboratory scale Kaldnes (k1) moving bed biofilm reactors (MBBRs) under partial nitrification-denitrification process were used for treatment of synthetic wastewater containing ammonium and glucose. The Anoxic and Aerobic reactors were filled to 40 and 50 %( v/v) to attach and retain biomass with k1 biofilm carriers, respectively. The favorite interna...

The use of anaerobic hydrolytic fermentation to develop more available carbon sources from domestic sewage influent particulate organic matter (POM) has received increasing attention. However, the slow hydrolysis rate POM limits application this technology. This study aimed improve source release efficiency by pH adjustment and reveal mechanism. Results showed that adjusting initial 3, 9, 11 en...

In this study, the co-digestion of orange pulp (OP) and cattle manure (CM) were investigated. The anaerobic process (40 d) five reactors prepared according to different carbon nitrogen (C/N) ratios (17, 26, 29, 35, 43.76) was completed. Anaerobic digestion (AD) investigated in batch (1000 mL) both biogas production measured every days soluble chemical oxygen demand (SCOD) value % removals deter...

Conventional wastewater treatment processes are challenged by the need to effectively reduce pollutant loads before disposal or reuse, as composition and concentration of contaminants in brewery change with time. This results variation oxidation-reduction potential (ORP) affluent. Hence, current study is aimed at application ORP a real-time tool monitor quality. Other physicochemical parameters...

The Cassava starch manufacturing wastewater (CSW) was used as a substrate to produce polyhydroxybutyrate (PHB) by Cupriavidus sp. KKU38. The acidogenic fermentation process of CSW was first conducted to obtain volatile fatty acids (VFAs), which are more efficient in PHB production than raw CSW. The effect on substrate concentration and nutrients, i.e. nitrogen and phosphorus concentrations, by ...
