A high flocculation performance composite flocculant was prepared with sodium alginate, polyaluminium ferric chloride and cationic polyacrylamide. And the composite flocculant was used in papermaking wastewater treatment. Results indicated that it achieve the best flocculation performance when the raw material mass ratio was 2:1:1, the dosage of the composite flocculant was 20 mg/L, and the rem...

groups, i.e., the group with less than 30 per cent of interstitial tissue and the group with 30 per cent or more of interstitial tissue. Edema, liver enlargement, abnormalities in thymol flocculation test, in cephalin cholesterol flocculation test, and in serum r-globulin concentration, and deformity of the hepatic veins in hepatic venograms were all significantly more frequently observed in th...

the present investigation provides a thorough study of eliminating soluble and colloidal elements of copper, iron, magnesium and zinc during estuarine mixing of gorganrood river water with caspian sea water in iran. the processes of flocculation were carried out in 10 aquariums in order to furnish the salinity in an interval of 0.3 - 4.4 ppt. the obtained result is indicative of non- conservati...

Microalgae have increasingly gained research interest as a source of lipids for biodiesel production. The wet way processing of harvested microalgae was suggested and evaluated with respect to the possible environmental impacts and production costs. This study is focused on the three key steps of the suggested process: flocculation, water recycling, and extraction of lipids. Microalgae strains ...

‘THE LENGTHY INCUBATION PERIOD and the subjective interpretation of degree of flocculation ai’e undesirable characteristics of the Hanger cephalin cholesterol flocculatiomi test (1). Several workers (2-4) have reported modifications either to shorten test time or to determine extent of flocculation mnstrumemitally. Inadequate sensitivity has been noted in some of these technics as well as inter...

The proposed procedure to produce low polluting effluent consists of a combination of coagulation-flocculation and membrane separation process. The main role of the coagulation-flocculation process is the simultaneous enhancement of removal efficiency and increase the permeate flux by minimizing the membrane fouling. Membrane fouling has a significant impact on the cost, design, and operation o...

An increase in the amounts of the globulin components of the serum has long been recognized in advanced states of liver disease (1, 2, 3), although the significance of the alteration has never been defined. It has been the basis of the Takata-Ara, Weltmann and the formol-gel reactions which have been used for many years in the diagnosis of liver disease. The nonspecific nature of these tests is...

Deletion of ribosomal protein L32 genes resulted in a nonsexual flocculation of fission yeast. Nonsexual flocculation also occurred when two other ribosomal protein genes, rpl21-2 and rpl9-2, were deleted. However, deletion of two nonribosomal protein genes, mpg and fbp, did not cause flocculation. Overall transcript levels of rpl32 in rpl32-1Δ and rpl32-2Δ cells were reduced by 35.9% and 46.9%...

Existing flocculation models for cohesive sediments are classified into two groups: population balance equation models (PBE) and floc growth models. An FGM ensures mass conservation in a closed system. However, an FGM determines only the average size of flocs, whereas a PBE has the capability to calculate a size distribution of flocs. A new stochastic approach to model the flocculation process ...
