Investigation was carried out through flotation tests, zeta potential measurements, turbidity determination and microscopic imaging.
The entire equipment assembly had been previously calibrated in terms of colour and turbidity determination.
Turbidity was determined using Hach model 2100P turbidity meter.
In this work, alternative, enzymatic clarification strategies of industrially pressed cherry juice were evaluated in a 24−1 factorial design set-up with addition of a pectinase, Pectinex Smash®, a protease, Enzeco, both enzyme preparations derived from Aspergillus spp., gallic acid, and tannic acid as factors, and determination of turbidity, protein, pectin, and phenolics as responses.
Depth-integrated 1 L water samples were collected for the determination of turbidity, total nitrogen (TN), nitrates, ammonia, total phosphorus (TP) and reactive phosphates in the laboratory using the standard methods for the examination of water and wastewater (Clesceri et al. 1998).
The aim of this study was to develop a method based on non-invasive turbidity measurements for in-line determinations of betamethasone content uniformity during the filling process of injections.
As said earlier, the turbidity was replaced by color determination taking into account the fact that turbidity is directly related to the color.
The residual turbidity of supernatants was determined.
Efficiency was evaluated by determination of reduction in turbidity of both the synthetic samples.
Turbidity optics were developed for the determination of particle size distributions [ 5– 7].
