Polymeric Flocculants and Flocculation
Journal of Macromolecular Science, Part C: Polymer Reviews, 1999Flocculation can be described as the agent-induced aggregation of particles suspended in liquid media into larger particles.

Evaluation of several flocculants for flocculating microalgae
Bioresource Technology, 2015Flocculation of microalgae with chitosan, polyacrylamide, Al2(SO4)3, NaOH and HNO3 was evaluated. Their flocculation efficiencies and optimal dosages were discussed. The effects of the flocculants on cells viability were also investigated and the cells were found to be intact during the flocculation process.

Are flocculants required in a flocculant process?
Environmental Engineering and Policy, 1998The effectiveness of solids abatement by pH increase was investigated using the jar test procedure with a bentonite tap water suspension and an urban wastewater and an oxidation pond effluent. The results indicated that, depending on the suspended particles and on the dissolved ions, pH values between 9.5 and 12 induced extensive solids elimination ...

Water Research, 2017
This paper is mainly a review of the author's previous research, which was aimed at establishing a theoretical protocol for the design and operation of flocculators based on data from experiments and simulations of the flocculation process. Flocculation is the main pretreatment process of the rapid sand filtration system, and the process produces ...

Flocculation and Flocculation Basins
Transactions of the American Society of Civil Engineers, 1955An important process in the treatment of water, sewage, and industrial wastes is the formation of suspended floes which can be effectively removed from the liquid by settling or filtration.

Flocculation study on spiral flocculator
Water, Air, and Soil Pollution, 1986Traditionally, the Jar Test has been used to assess the suitability of flocculation treatment for a given raw water. Unfortunately, the Jar Test suffers from a number of disadvantages. The new method of assessment of flocculation, Spiral Flocculator, has been claimed to be a better method than the Jar Test apparatus and a good method for continuous ...

Yeast flocculation: factors affecting the measurement of flocculence
Canadian Journal of Microbiology, 1988The physical meaning of the residual absorbance of a yeast suspension after flocculation and settling has been investigated. Starting with a dispersed suspension, agitation accelerates flocculation by increasing the probability of collision between particles. As flocculation advances, agitation also breaks the flocs. A stationary state is reached when

A FLOCCULATION TEST FOR MODERATELY FLOCCULENT BREWING YEAST
Journal of the Institute of Brewing, 1975A modification of the original Helm et al. method was used to determine the flocculation of a moderately flocculent strain of Saccharomyces carlsbergensis. This test appeared to be more useful than methods adapted from Greenshields or Kato & Nishikawa, and made it possible to monitor flocculation trends during the course of fermentation. The effects of

The flocculation of algae with synthetic polymeric flocculants
Water Research, 1972Abstract The flocculation of a pure algal culture of Chlorella ellipsoidia , was evaluated by means of measurements of filtration rate, light transmission and electrophoretic mobility, at algal concentrations of 50–3000mg l −1 , polymer concentrations of 0.01–1000 mg 1 −1 at pH 4–7.
