Turbidity sensors can be used to continuously monitor the evolution of pollutant mass discharge. For two sites within the Paris combined sewer system, continuous turbidity, conductivity and flow data were recorded at one-minute time intervals over a one-year period. This paper is intended to highlight the variability in turbidity dynamics during wet weather. For each storm event, turbidity resp...

Seasonal turbidity patterns and event-level hysteresis analysis of turbidity verses discharge in four 1 km headwater catchments in California’s Sierra Nevada indicate localized in-channel sediment sources and seasonal accumulation-depletion patterns of stream sediments. Turbidity signals were analyzed for three years in order to look at the relationships between seasonal turbidity trends, event...

Coastal water-quality is both a primary driver and also a consequence of coastal ecosystem health. Turbidity, a measure of dissolved and particulate water-quality matter, is a proxy for water quality, and varies on daily to interannual periods. Turbidity is influenced by a variety of factors, including algal particles, colored dissolved organic matter, and suspended sediments. Identifying which...

Mitochondrial factor and cell cytokines play important roles in the incidence of vascular dementia (VD), but their correlations with inflammatory and mitochondrial factors and the role of both in the kidney essence deficiency pattern and phlegm turbidity blocking orifice pattern are not clear. This study was aimed at studying the correlations between the serum mitochondrial factor and cell cyto...

AIMS To investigate the cause of turbidity in reconstituted lyophilised plasmas and to determine its effect on coagulometers. METHODS The turbidities of 20 normal plasmas and 16 reconstituted lyophilised plasmas were determined by comparing a 1 in 4 dilution in distilled water with a standard suspension in an Aminco Fluorocolorimeter (American Instrument Co) in nephelometric mode. The turbidi...

The effect of vanadate on the ATP-induced disruption of trypsin-treated axonemes and the ATP-induced straightening of rigor wave preparations of sea urchin sperm was investigated. Addition of ATP to a suspension of trypsin-treated axonemes results in a rapid decrease in turbidity (optical density measured at 350 nm) concomitant with the disruption of the axonemes by sliding between microtubules...

The goal of this study was to evaluate tannic acid as a coagulant in turbidity removal. Tests were designed using Taguchi method and carried out on the synthetic and natural turbid samples. In order to optimize turbidity removal by tannic acid, seven factors including pH, coagulant dosage, rapid mixing rate, slow mixing rate, slow mixing time, sedimentation time and initial turbidity were inves...

Drinking water for residents who live in flood area is the concern of government and environmental management. Using natural coagulants to transform into potable order reduce number chemical (aluminum salt) that have a negative impact on human health. The results flocculation procedure using agricultural residue extracts, dragon fruit branches (DFBE) avocado seeds (ASE), did not meet Vietnamese...

Flume experiments were performed to study the flow properties and depositional characteristics of high-density turbidity currents that were depletive and quasi-steady to waning for periods of several tens of seconds. Such currents may serve as an analogue for rapidly expanding flows at the mouth of submarine channels. The turbidity currents carried up to 35 vol.% of fine-grained natural sand, v...

Chondroitin sulfate (CS) has been accepted as an ingredient in health foods for the treatment of symptoms related to arthritis and cartilage repair. However, CS is poorly absorbed through the gastrointestinal tract because of its high negative electric charges and molecular weight (MW). In this study, poly-ion complex (PIC) formation was found in aqueous solutions through electrostatic interact...
