Abstract :The toxicity of a sediment pore water and an effluent was characterized using Toxicity Identification Evaluation (TIE) procedures. ...
This creates a huge issue in brewery effluent, as yeast are a dominant material released into effluent. Also, we are on a set timeline to reach our market. Waiting 5 days for effluent BOD sample results is a limiting factor in the brewery industry, as BOD content is our biggest effluent obstacle. ...
Inline measurements of gas composition, production and effluent chemical oxygen demand were sufficient for reliable model calibration of these same outputs. More detailed characterization of influent and effluent is required if organic acid concentrations for pH control are needed. ...
In this case, odors are produced especially in the summer months of August and September. Gas phase characterization Biotek analyzed the effluent composition of the ventilation shaft in order to find the most accurate solution in terms of media selection. ...
It generates large amounts of effluent that are highly loaded with organic hazard wastes. Such effluent is considered one of the most obnoxious materials in the leather industry, causing serious environmental pollution and health risks. The effluent is characterized by high concentrations of the pollution parameters. ...
Struvite precipitation was shown to be feasible in complex matrices as agro-industrial effluents, characterized by high NH4+, alkalinity, solids and organic content, and interfering ions such as Ca2+ and K+. ...
A sulfate-crosslinked chitosan (SCC) was prepared for effective detoxification of hexavalent chromium (Cr(VI)) from effluents. SCC was characterized using Fourier transform infrared, X-ray diffraction, scanning electron microscopy and energy dispersive X-ray studies. ...
This study provided insight into the characterization of secondary effluent from a wastewater treatment plant located in northeastern China. The secondary effluent was separated into three fractions, the dissolved, the near-colloidal and the suspended, to study their individual characteristics. ...
If influent flow and chemistry are high enough or strong enough then the effluent pH diverge from and remain out of the pre-programed set-point ranges. ...
In the present study, we conducted laboratory exposures that examined estrogenic, androgenic, and thyroid‐related endocrine responses in marine hornyhead turbot (Pleuronichthys verticalis) exposed to CECs from municipal effluents with two degrees of treatment. Fish were exposed for 14 days to environmentally realistic concentrations of effluent (0.5%) and to a ...
To inform future monitoring and assessment of chemicals of emerging concern (CECs) in coastal urban watersheds, the occurrence and fate of more than 60 pharmaceuticals and personal care products (PPCPs), commercial/household chemicals, current use pesticides and hormones were characterized in two effluent‐dominated rivers in southern California, USA. ...
The study was undertaken over a period of 4 years, comprising monitoring of influent and effluent constituents together with a full characterization of the behaviour of the units (tracer studies, mathematical modelling of chemical oxygen demand (COD) decay, characterization of solids in the filter medium). ...
The MBR was operated with fouled and cleaned membranes, at a time. DOM, mixed liquor, and effluent were characterized by fractionation and fluorescence excitation–emission matrix (EEM) spectroscopy. Results showed DOM removals of 82% during the MBR operation with the fouled membrane. The DOM characterization indicated that most of ...
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 ...
The binding interactions of 1‐naphthol with effluent and whole natural dissolved organic matter (DOM) samples were analyzed by using a fluorescence quenching technique. Nonfractionated DOM samples from Lake Biwa (Japan), creek water, treated sewage effluents, and an extracted Lake Biwa fulvic acid (LBFA) standard were used as quenchers and compared at the same ...
A pilot-scale dual-stage membrane bioreactor (dsMBR) incorporating two ultra-filtration (UF) side-stream membrane modules was designed, constructed, operated and evaluated on-site for treating high-strength textile effluent. The effluent stream was characterised by a COD range of between 45 to 2,820 mg/L and an average BOD of 192.5 mg/L. The dsMBR achieved an average COD reduction of 75% with a ...
The emerging interest on organic (eco-)toxic compounds requires characterizing treated effluent and treatment technologies concerning ecotoxicologic aspects and micropollutants. ...
Great amounts of wastewater are generated, with properties depending on the type of wood, treatment process, final product and water reusing, among others. These effluents are characterized by a high chemical oxygen demand, low pH and nutrients limitation. ...
Theoretical studies have shown that discharges from retention tanks could have a negative impact on the WWTP's (Wastewater Treatment Plant) effluent. Characterization of such discharges is necessary to better understand these impacts. This study aims at: (1) characterizing water quality during emptying of a tank; and (2) ...
Both technologies showed a similar performance with regard to heterotrophic kinetic and stoichiometric parameters and organic matter effluent concentrations. The influent was characterized by means of its COD fractions and the average removal percentages for COD concentrations were around 97% for both plants in spite of influent COD fluctuation, temperature ...
