This pilot study was designed to evaluate the efficacy of membrane microfiltration in treating secondary wastewater effluent conditioned with various inorganic coagulants. The increased concentration of SON and SCOD produced biologically during activated-sludge culture start-up had a generally higher molecular weight distribution than normal secondary effluent, with considerably more organics in the greater-than molecular weight range.

Get this from a library. Characterization and separation of secondary effluent components by molecular weight. [Philip L Levins; Arthur D. Little, Inc.; United States. Environmental Protection Agency.] -- The purpose of the research was to explore the appropriateness of various methods for separating and characterizing municipal secondary waste effluent.

During the experiment, the system was operated under dead-end mode at constant temperature (20 ± 1 °C). A synthetic secondary wastewater effluent was used as feed solution to grow the biofilm on the membrane according to Nopens et al.A mL activated sludge collected from a lab aerobic activated sludge system was added into the tank at the beginning to enhance the formation of by: Gravity-driven membrane system for secondary wastewater effluent treatment: Filtration performance and fouling characterization Article in Separation and Purification Technology April The effluent from the D0-stage contained a lower amount of high molecular weight fragments and a higher amount of low molecular weight fragments versus the O-stage filtrate.

Characterization of the source waters and MF foulants has been limited to gross molecular characterization (Jarusutthirak et al.,Shon et al., ). A detailed chemical analysis of the wastewater effluent is critical to the understanding of the chemical dynamics of Cited by:   wastewater characterization.

Whenever a major wastewater flow needs to be treated, the first alternative that should normally be considered is the use of a biological process as this is one of the cheapest complete treatments and the amount of waste generated is relatively low.

Dissolved organic matter (DOM) in wastewater and reclaimed water is related to water quality, safety, and treatability. In this study, DOM was characterized through a fingerprint analysis method for DOM characterization using resin fractionation followed by size exclusion chromatography (SEC).

Resin fractionation was used in the first step to divide the DOM in water samples into six resin Cited by: SPECIAL COMPONENTS Most components in wastewater are not the direct target for treatment, but they contribute to the toxicity of the wastewater, either in relation to the biological processes in the treatment plant or to the receiving waters.

The substances which are found in the effluent might end up. Evaluation of an advanced wastewater treatment system that combines photocatalysis with ceramic membrane filtration for the treatment of secondary effluent was undertaken.

The results showed that, after photocatalysis and ceramic membrane filtration, the removal of dissolved organic carbon and UV was 60% and 54%, respectively, at a concentration of 4 g/L of by: 1.

When a discharger's effluent is found to be unacceptably toxic, regulatory agencies often require a Toxicity Reduction Evaluation (TRE) to be performed in an effort to eliminate or reduce the toxicity to acceptable levels.

The major tool for TREs is a series of procedures termed a Toxicity Identification Evaluation (TIE).Cited by: ments, and use of a separation technique with the C, solid phase extraction (SPE) resin.

Each effluent is characterized in Tier 1 by performing the manipulations at the initial pH (pH i) of the effluent. Tier 2 consists of the Tier 1 manipulations combined with pH. The main objective of this study is to characterize and find a potential use of textile effluent treatment plant (ETP) sludge produced in Bangladesh.

Textile ETP sludge collected from the local textile industries have been characterized in the laboratory. The physicochemical and engineering properties of the sludge have been studied. Collected ETP sludge has been processed to get cement Cited by: Fluorescence spectroscopy coupled with parallel factor analysis (PARAFAC) has been widely used to characterize dissolved organic matter (DOM).

Characterization is based on the intensity and location of independent fluorescent components identified in models constructed from excitation–emission matrices (EEMs). Similar fluorescent components have been identified in PARAFAC studies across a. Industrial Effluent Characteristic Study will involve the qualitative and quantitative measurement of industrial influent and effluent which normally would take 24 hours over a period of three days.
