form into an aggregated lumpy or fluffy mass; "the protoplasms flocculated" cause to become a fluffy or lumpy aggregate; "The chemist flocculated the suspended material
To convert into floccules or flocculent aggregates; to make granular or crumbly; as, the flocculating of a soil improves its mechanical condition
A mass loosely formed by the aggregation of a number of fine suspended particles Aggregates destabilized particles into larger and more easily settleable masses
A soluble material which is added to a suspension to increase the viscosity The following are flocculants--vinegar, gelatine, epsom salts (magnesium sulphate) and aluminum sulfate When using aluminum sulfate or epsom slats as flocculant add 1/2 to 1%
Essentially the same as a coagulant, this chemical (such as alum) is used to combined suspended alkaline material and/or algae into a heavy gel, which sinks to the bottom for vacuuming
large scale treatment process involving gentle stirring whereby small particles in flocs are collected into larger particles so their weight causes them to settle to the bottom of the treatment tank
The tendency of yeast to clump together and settle out as fermentation draws to a close Yeast which have low flocculation will tend to remain in suspension longer; they will ferment the beer more fully, but may tend to cause haze in the finished beer unless finings or filtration are used Yeast which have high flocculation will tend to settle out quickly when fermentation nears completion; they may leave more residual sugars and/or take longer to finish fermenting, and will generally yield very clear beer without finings or filtration
(x) means a process to enhance agglomeration or collection of smaller floc particles into larger, more easily settleable particles through gentle stirring by hydraulic or mechanical mechanisms
The agglomeration of finely divided suspended solids into larger, usually gelatinous, particles; the development of a "floc" after treatment with a coagulant by gentle stirring or mixing
The process of bringing together destabilized or coagulated particles to form larger masses which can be settled and/or filtered out of the water being treated
The change which takes place when the dispersed phase of a colloid forms a series of discrete particles which are capable of settling out from the dispersion medium In geological processes, flocculation is almost inevitably a result of a colloidal solution mixing with a solution containing electrolytes, e g , sea water
A large scale treatment process involving gentle stirring whereby small particles in flocs are collected into larger particles so their weight causes them to settle to the bottom of the treatment tank, (see coagulation)
The formation of clumps or masses Usually referring to yeast in later stages of fermentation Can also be used referring to proteins in a cold or hot break
the process by which insoluble, fine particles are caused to precipitate from suspension Alum works by this principle However, other more modern polymer-type liquids or tablets accomplish the same net result, without having to generate large amounts of additional gelatinous precipitate
The water-treatment process after coagulation that uses gentle stirring to cause suspended particles to form larger, aggregated masses (floc) The aggregates are removed from the water by a separation process (e g , sedimentation, flotation, or filtration)
Large scale treatment process whereby small particles in flocs are collected into larger particles so their weight causes them to settle to the bottom of the treatment tank This is accomplished by gentle stirring
