WebFlocculation has been defined as the reversible, non-sexual aggregation of yeast cells that may be dispersed by specific sugars or EDTA. The addition of nutrients other than sugars has been demonstrated not to reverse flocculation. [8] WebPublic groundwater supply is usually well water because springs are rare. A well is a device to draw the water from the aquifer. Deeper wells (more than 100 feet) have less turbidity, more dissolved minerals, and less bacterial count than shallow wells. Shallow wells have less natural filtration of water due to less depth of the soil.
