Resumen

SUMMARYTo assess unfiltered drinking water as a source of cryptosporidium infection in patients with the acquired immunodeficiency syndrome (AIDS) the prevalence of cryptosporidiosis among persons with AIDS in Los Angeles County was assessed by water service area. One water distributor, serving approximately 60% of the county's residents (area B), has consistently employed filtration. The other company, which serves the remainder of the county (area A), did not institute nitration until mid-December 1986. This difference provided a ‘natural experiment ’ in which to assess the effect of municip

Resumen

A novel copolymer PADA which has two functions of flocculation and surface activity was synthesized in aqueous solution. The copolymer was applied to filtration aiding on wet-process phosphoric acid (WPA). The results show that PADA can increase the filtration rate of the phosphoric acid slurry and decrease the moisture of the filter cake. The mechanism of filtration aiding was studied. PADA neutralizes the surface potential of the phosphogypsum and makes the microcrystal particles flocculate to conglobation, which indicate that electrostatic neutralization and flocculation might be the action

Resumen

For solid–liquid separation, filter meshes are still used across large areas today, as they offer a cost-effective alternative, for example, compared to membranes. However, particle interaction leads to a continuous blocking of the pores, which lowers the flow rate of the mesh and reduces its lifetime. This can be remedied by filter aids. In precoat filtration, these provide an already fully formed filter cake on the fabric, which acts as a surface and depth filter. This prevents interaction of the particles to be separated with the mesh and thus increases the service life of the mesh. In this

The global wine market, having recently entered into full crisis, is suffering some changes in its production and marketing. The reasons for these changes are mainly due to new trends in consumer demand for wine safety and quality standards at low cost. Social cellars, in order to be included in this new trend, should focus on the rationalization of the production techniques to reduce the costs and improve the quality of wine. In the case of winemaking for the production of a wine stored in a bag-in-box, filtration is a very important technique because it gives the finished product clearness a

The drainage of filtrates during mat formation in a brownstock washer directly impacts the washer’s productivity and indirectly affects its efficiency. In this paper, the role of entrained air on filtration through a formed mat during displacement as it occurs in brownstock washing was investigated. It was shown how chemical treatments, such as wash aids and fiber surface chemistry, influence air entrainment and, thereby, washer productivity and efficiency. By minimizing air entrained within a formed mat, displacement filtration rates and wash ratios were shown to improve. With this knowledge,

Granular media filtration is an important treatment process for various reuse applications. Size density, and attachment strength of filter deposits produced by the interaction of effluents with alum, alum-polymer aids and cationic polymers as primary flocculants and the filter media during contact filtration were calculated and compared using existing filtration models. Secondary effluent filtration without flocculant addition was relatively ineffective. Effective alum dose for contact filtration ranges 10 - 20 mg/L.

Angiotensin-converting enzyme inhibitor-induced renal failure is now a well-recognized phenomenon that appears to occur almost exclusively in patients with a preexisting reduction in renal perfusion pressure, especially those with renovascular disease. In the latter group of patients, renal failure probably results from some combination of reduced poststenotic renal perfusion pressure and a unique disturbance in the autoregulation of glomerular filtration rate. Although traditionally regarded as functional and reversible, recent animal studies suggest that angiotensin-converting enzyme inhibit

In this research, polymeric flocculants were used to improve floc strength prior to filtration on a dissolved air flotation (DAF) plant in an attempt to prevent filter breakthrough. A modified jar test procedure using a PDA (photometric dispersion analyser) optical flocculation monitor was developed in order to evaluate the system floc strength. Filtration trials were carried out on a pilot

Resumen

According to regulations, the cross-section of Wangjiawopeng is regarded as a national control section of the Daling River. The water quality of the section must meet the surface water level III standard. According to the survey, the total phosphorus in the effluent from the sewage plant in Jianchang exceeds the standard is the main reason for the failure of the water quality. In order to make the cross-section water quality reaching standard, it is necessary to carry out the advanced treatment of phosphorus in the sewage plant.

Resumen

Beer is a complex mixture consisting of hundreds of chemical substances. Some of them are macromolecules, such as proteins and polysaccharides that together with polyphenolic compounds form poorly soluble complexes causing beer turbidity or cold colloidal turbidity. Furthermore, beer turbidity can be caused also by procedural particles entering into beer during brewing process (filtration and stabilization aids) or by foreign particles from external environment (mechanical impurities). If turbidity, sediment or individual particles occur in filtered and stabilized beer, their origin must be de

Resumen

The application of laser diffraction particle monitoring to the performance optimisation of a pilot clarifier and full-scale rapid gravity filters (RGF), operating on water supply works in Hampshire, is described. Furthermore the dosing of powdered activated carbon (PAC) into the works' clarifiers has been evaluated in terms of RGF performance. A costly proposal to install a third filter medium was subsequently abandoned when it was found that particle numbers in the filtered water were consistently below 1×102/ml. Various combinations and doses of coagulants and flocculant aids, shown to give

Resumen

Abstract The effect of perfluorochemical blood substitutes (eg, Oxypherol or Fluosol-DA) on red cell deformability was investigated because these emulsions are in direct contact with red cells when they are used as temporary circulatory aids. Erythrocyte deformability was assessed by a constant volumetric flow rate filtration method. The results of in vitro incubation experiments indicate that perfluorotributylamine causes the deformability of human red cells to decrease significantly in the presence of plasma. However, there is no obvious loss in the deformability when washed cells are used.
