Responses of corals to chronic turbidity
Scientific Reports, 2020 Dredging increases suspended sediment concentrations (SSCs), causing elevated water turbidity (cloudiness) and light attenuation. Close to dredging, low light periods can extend over many days, affecting phototrophic epibenthic organisms like corals.

Permanent Turbidity-Standards [PDF]
Applied Microbiology, 1967 Permanent turbidity reference standards suitable for measurement of microbial suspensions were prepared by suspending finely divided titanium dioxide in aryl sulfonamide-formaldehyde or methylstyrene resins. Turbidities of these standards, adjusted to a useful range for microbiological and immunological studies, were compared with other reference ...

Implementation and Calibration of an IoT Light Attenuation Turbidity Sensor
, 2022 Turbidity is an important characteristic of water quality that can indicate the presence of undesirable suspended particulate matter. Having access to an inexpensive and effective turbidity sensor unlocks numerous Internet of Things (IoT) possibilities ...

IDENTIFICATION OF WATER TURBIDITY WITH TURBIDITY SENSOR BASED ON ARDUINO
Jurnal Riset Informatika, 2021 Water is an important need for all living things, especially humans. Humans need water with quality that meets the physical, microbiological, chemical, and radiological requirements contained in the mandatory and additional parameters. The selection of these parameters is very important to meet the requirements of good water, namely tasteless, odorless,

Powerful turbidity currents driven by dense basal layers
Nature Communications, 2018 Seafloor sediment flows (turbidity currents) are among the volumetrically most important yet least documented sediment transport processes on Earth. A scarcity of direct observations means that basic characteristics, such as whether flows are entirely ...

Trapping and escape in a turbid medium [PDF]
The Journal of Chemical Physics, 2017 We investigate the absorption of diffusing molecules in a fluid-filled spherical beaker that contains many small reactive traps. The molecules are absorbed either by hitting a trap or by escaping via the beaker walls. In the physical situation where the number N of traps is large and their radii a are small compared to the beaker radius R, the fraction

Development and analysis of environmentally neutral, biodegradable, novel flocculants for drinking water treatment [PDF]
, 2013 The objective of this work is a systematic study of the use of oleaginous-seed press-cake extracts of Moringa oleifera lam, hemp, sunflower, rapeseed, strawberry, lime and raspberry as bioflocculants for the removal of suspended solids in the process of ...
