The effect of the absence of trace elements on the conversion of a mixture of volatile fatty acids by a distillery anaerobic granular sludge was investigated. Two UASB reactors were operated under identical operational conditions except for the influent trace metal concentrations, during 140 days. Experiments were carried out in three periods, where different organic loading rates (OLR) were ap...

Abstract machines for the strong evaluation of λ-terms (that is, under abstractions) are a mostly neglected topic, despite their use in the implementation of proof assistants and higher-order logic programming languages. This paper introduces a machine for the simplest form of strong evaluation, leftmost-outermost (call-by-name) evaluation to normal form, proving it correct, complete, and bound...

The disposal of post methanated diluted effluent (PMDE) from the distillery and fly ash from the thermal power plants has assumed a cosmic dimension in India because they are produced in huge quantities. Thus, their gainful utilization is imperative. In the present paper their gainful utilization for sustainable development has been discussed herein. The results have revealed that the electrica...

Distillery sludge is a major source of aquatic pollution, but little known about their microbial community and association with the organic metal pollutants. Sugarcane molasses-based distillery an important industry in India, although waste usually treated prior to disposal, treatment often inadequate. The adverse effects pollutants sugarcane on biodiversity abundance disposal site have not bee...

A control law based on fuzzy logic features was developed and validated for an anaerobic wastewater treatment (AWT) process. The controlled variable was the concentration of Volatile Fatty Acids (VFA) in the anaerobic reactor and the manipulated variable was the input flow rate. In order to use it as the input in a Mamdani-inference fuzzy set, the controlled variable was treated using an algori...

A control law based on Fuzzy Logic was developed and validated for an anaerobic wastewater treatment process. The controlled variable was the concentration of Volatile Fatty Acids (VFA) in the reactor and the manipulated variable was the input flow rate. In order to use it as the input of the fuzzy sets, the controlled variable was treated using an algorithm of interpolation, extrapolation and ...

This study describes the temporal and spatial variability of bacterial communities within a combined sewer system in England. Sampling was conducted over 9 months in a sewer system with intensive monitoring of hydraulic conditions. The bacterial communities were characterized by 16S rRNA gene-targeted terminal restriction fragment length polymorphism analysis. These data were related to the hyd...
