Sustainable wastewater treatment chemicals in a food processing plant
A food ingredients manufacturer was using an inorganic aluminium metal salt with pH correction to treat their effluent. This chemical regime refused to give them any real control over their effluent characterisation. Their effluent plant required constant monitoring and adjustment. The inability to control the characterisation of the effluent exiting the site meant non-compliance to the ...

Simulation of granulation index and its utility for predicting percentage granules in UASB reactors
This paper researches on the development of a dimensionless number for predicting percentage granulation in Upflow Anaerobic Sludge Blanket (UASB) reactors for treating biodegradable wastewaters. A Biomass Granulation Index (BGI) has been framed based on the experimental work conducted using laboratory scale UASB reactors. This index depends on mixing in the sludge bed, induced due to biogas and ...

Use of chemically treated sawdust for chromium removal from aqueous solutions: effect of process parameters
This paper reports the effect of various process parameters on the removal of chromium from aqueous solution using formaldehyde–treated timber industry waste (sawdust). The adsorbent was characterised by Scanning Electron Microscopy (SEM) and Energy Dispersive X–Ray Analysis (EDAX). Influence of chromium concentration, pH, adsorbent dose and contact time on chromium removal from aqueous solution ...

Artificial intelligence based model for optimization of COD removal efficiency of an up-flow anaerobic sludge blanket reactor in the saline wastewater treatment
The complex non-linear behavior presented in the biological treatment of wastewater requires an accurate model to predict the system performance. This study evaluates the effectiveness of an artificial intelligence (AI) model, based on the combination of artificial neural networks (ANNs) and genetic algorithms (GAs), to find the optimum performance of an up-flow anaerobic sludge blanket ...

Treatment of cornstalk fibrous pulp wastewater using Anaerobic Baffled Reactor (ABR): effect of shock loading rates
The treatment of cornstalk fibrous pulp wastewater in Anaerobic Baffled Reactor (ABR) was investigated. The effect of shock loading rates, such as various hydraulic and Organic Loading Rates (OLRs), on the performance of ABR was assessed. When the influent COD concentration was kept 4000 mg/L, the Hydraulic Retention Time (HRT) was decreased from 40 h to 18 h, the removal efficiency of COD was ...

An effective feature selection approach using hybrid particle swarm optimisation with spectral projected gradient algorithm for an up–flow anaerobic filter
Wastewater treatment plant (WWTP) helps to overcome water from excessive pollution. Chemical oxygen demand (COD) or biological oxygen demand (BOD) is the measure for the wastewater effluents. Up–flow anaerobic filter (UAF) is used for the removal and digestion of organic matter present in wastewater. In this work, the performance of the UAF with cheese–dairy wastewater was considered for ...

How Chemicals Are Used in Wastewater Treatment
There are many different steps to process wastewater, but one of the most important is using the chemical dosing system. This system involves a chemical feed station delivering a chemical substance into sewage, sludge, and foul water. Pumping systems like these at wastewater treatment plants usually consumes between 10% and 15% of the plant’s energy, making this process a significant part ...
