dewatering
The flocculating activity of polyelectrolytes is determined in aqueous kaolin suspensions and also in dewatering of an active sludge.
      
The annual average sludge production was 46.3 m3d-1, the annual average dosage for dewatering was 40 kg d-1.
      
Even when little saccharification occurred, the enzyme facilitated separation of water, fiber, and ash, so cellulase treatment could be an effective means for dewatering pulp sludges.
      
Dewatering of the released osmolyte would occur in two additional steps, consisting of its hydrolysis and the subsequent active uptake of its metabolites.
      
Dewatering and decontamination of artificially contaminated sediments during electrokinetic sedimentation and remediation proces
      
At the temperature of 243°C the process of dewatering came to the end and the sum of lost crystal water reaches 33.30 wt%.
      
The inferred metal-bearing hot brines were probably episodically expulsed during the dewatering of the basin, depositing their mineralization in the more permeable fault and karstic zones associated with the uplift of the St.
      
The dendritic nature of the gold is secondary and is the result of dewatering of the amorphous hydrocarbon-silica phase and crystallization of gold into syneresis fractures.
      
Fluids may have been derived from dewatering of Variscan-driven deformation to the south of the carbonate platform, with fluid flow through major fracture zones and basal clastic aquifers.
      
These fluids are interpreted as the product of metamorphic dewatering caused by enhanced heat flow, although it is also possible that the fluids were derived from coeval granites.
      
Dewatering of the Domeyko Basin expelled brines along faults, some of which had earlier guided the location of porphyry deposits.
      
These results suggest that entrapped growing bacteria can exert a substantial stress on their surroundings and that dewatering of the starved cell population in an entrapped system may occur.
      
The background for the study was that anaerobic storage of activated sludge, which often takes place at wastewater treatment plants before dewatering, causes a deterioration of the dewaterability.
      
CelA treatment enhanced the physical properties (stretch and tensile index) of paper from wheat straw, while dewatering properties were slightly diminished.
      
An increase in mechanical strength of paper and a decrease in pulp dewatering properties were found, indicating that CelB treatment can be considered as a biorefining.
      
The subsidence that occurs on dolomitic terrain following development or during dewatering has given dolomite a notorious reputation and engineers and geologists became reluctant to recommend development on the material.
      
In order to protect the hot springs from dewatering and loss of pressure due to largescale quarrying and deep drilling, it is necessary to identify the sources and routes whereby the thermal water travels to its resurgences in the Avon valley.
      
The physical, chemical, and dewatering characteristics of 19 bottom sediments from Osaka Bay, Japan, have been analyzed to aid in the development of sediments in the coastal bay area.
      
There are significant relationships between all the dewatering parameters.
      
This analysis was conducted with reference to guidelines that define a primary zone of underground mining influence where dewatering of aquifers is to be expected.
