water treatment chemicals industry forecasts china focus for sale
The behavior of an aggregate of colloidal particles, or floc, in a water treatment process is dependent upon its physical characteristics, including size, strength, density, and permeability. It is no exaggeration to say that the success of a water treatment operation can be gauged by the properties of the aggregates produced.
Characterization of ballasted flocs in water treatment
Ballasted flocculation is widely used in the water industry for drinking water, municipal wastewater, storm water and industrial water treatment. This gravity-based physicochemical separation process involves the injection of a ballasting agent, typically microsand, to increase the floc density and size.

Floc sensor prototype tested in the municipal wastewater
particles (flocs) was tested in the municipal wastewater treatment plant. Results obtained from the tests with a prototype give a basis for the actual floc sensor to be developed. The floc sensor would be suitable to improve the coagulation dosage control strategy and potentially will substitute some of the more expensive water quality sensors.

Coagulation performance and floc characteristics
Floc strength factor (S f) and recovery factor (R f) are well-established parameters for describing floc strength and recovery ability and can be calculated as follows : (4) Strength factor = d 2 d 1 × 100 (5) Recovery factor = d 3 d 1 × 100 where d 1 is the average floc size of the steady phase before breakage or shear phase, d 2 is the floc

Because the flow of waste water from a dairy comes in slugs, a hydraulically loading wastewater treatment is a distinct possibility. The amount of water used in a dairy, which can generate average wastewater ranges between one and six gallons for every one gallon of milk processed, is the source of the hydraulic load.

Rapid Structure Characterization of Bacterial Aggregates
While the structure of bacterial aggregates formed in wastewater treatment is recognized to be an important determinant of the efficiency of various processes including sedimentation, thickening, and sludge dewatering, very few methods exist for rapidly quantifying this structure.
