Coagulation and Flocculation

Environmental Engineering, 2022
At varying sample pH values, the coagulation process may suffer from less than optimum ions being formed in solution. pH that is too low may not allow the coagulation process to proceed, while high pH can cause a coagulated particle to redisperse.

Bio-flocculation of Microcystis aeruginosa by using fungal pellets of Aspergillus oryzae: Performance and mechanism.

Journal of Hazardous Materials, 2022
Algal blooms caused by eutrophication are global phenomena that seriously threaten the sustainable use of freshwater resources. Traditional water treatment chemicals often typically lead to high levels of residue and cause damage to the morphology of ...

Enhanced Secretions of Algal Cell-Adhesion Molecules and Metal Ion-Binding Exoproteins Promote Self-Flocculation of Chlorella sp. Cultivated in Municipal Wastewater.

Environmental Science and Technology, 2021
The mechanism of self-flocculation remains unclear, partially impeding its efficiency enhancement and commercial application of microalgae-based municipal wastewater (MW) bioremediation technology. This study revealed the contributions of exoproteins [PN,

Flocculation study on spiral flocculator

Water, Air, and Soil Pollution, 1986
Traditionally, 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 ...

Red Mud-Based Polyaluminum Ferric Chloride Flocculant: Preparation, Characterization and Flocculation Performance

Environmental Technology & Innovation, 2021
In this work, red mud was used as raw material to extract Al and Fe with hydrochloric acid. The high-efficiency polyaluminum iron chloride (PAFC) flocculant was prepared via adjusting the pH of the leaching solution, the molar ratio of aluminum and ...

Flocculation and Flocculation Basins

Transactions of the American Society of Civil Engineers, 1955
An 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.

Evaluation of several flocculants for flocculating microalgae

Bioresource Technology, 2015
Flocculation 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.

Yeast flocculation: Flocculation onset and receptor availability

Yeast, 1993
AbstractFlocculent strains of brewing yeast grow and ferment as single cells and flocculate in the stationary phase of growth. The switch from single‐celled yeast growth to multi‐celled aggregation, flocculation onset, is of critical importance to the brewing industry.
