Synthetic fibers enter wastewater treatment plants together with natural fibers, which may affect efficiency, a fact not considered in previous studies. Therefore, the aim of present study was to evaluate efficiency coagulation/flocculation process for removal mixture textile from different water matrices. Natural and synthetic (100 mg/L; cotton, polyacrylonitrile, polyamide) were added matrix,...

The fact that water is the most important material used by mankind defines the importance of water purification. Wastewater and industrial effluent treatment require removal of suspended solids for purification and possible re-usage. The removal can be accomplished by gravitation (very slow), by coagulation (dependent on electric charge situation) and by flocculation (not dependent on electric ...

The experimental evidence and theoretical explanations of stable cluster formation in colloidal suspensions are reviewed. The clusters form in the intermediate range between a stable suspension built up by singlets and the irreversible coagulation or gelation of the suspension. The stable clusters develop as a result of a balance between competing short range attraction and long range repulsion...

The removal of the Microsporidia, Encephalitozoon intestinalis, feline calicivirus and coliphages MS-2, PRD-1, and Fr were evaluated during conventional drinking water treatment in a pilot plant. The treatment consisted of coagulation, sedimentation, and mixed media filtration. Fr coliphage was removed the most (3.21 log), followed by feline calicivirus (3.05 log), E. coli (2.67 log), E. intest...

ater suppliers need information about the removal efficiency of Cryptosporidium and potential surrogate parameters over a broad range of water quality and treatment conditions. These data can be obtained by tracking environmental concentrations of Cryptosporidium through full-scale treatment plants or feeding larger numbers of oocysts through pilot-scale facilities. Table 1 shows published Cryp...

Abstract During our research work, we examined the removal of contaminants from synthetically produced bathing waters using different coagulants and studied efficiency mechanism coagulation-flocculation processes in detail. In performed experiments with two types (iron(III) chloride polyelectrolyte) compared their efficiencies. The zeta potential its change were monitored as a qualifying parame...

During operation of most water treatment plants, spent filter backwash water (SFBW) is generated, which accounts about 2-10% of the total plant production. By increasing world population and water shortage in many countries, SFBW can be used as a permanent water source until the water treatment plant is working. This data article reports the practical method being used for water reuse from SFBW...

background; turbidity removal using inorganic coagulants such as iron and aluminum salts in water treatment processes causes environmental and human health concern. historically, the use of natural coagulant to purify turbid water has been practiced for a long time. recent research indicates that descurainia sophia seed can be effectively used as a natural coagulant to remove water turbidity. m...

Despite the widespread use of ionic polymer flocculants in sugar refineries, there is still insufficient knowledge on relationship between properties and efficiency flocculation. This paper describes performance poly(sodium acrylate-co-acrylamide) (poly(SA-co-AAm)) as an anionic flocculant flocculation–coagulation sugarcane juice from factory Gempolkrep PTPN X Mojokerto. Poly(SA-co-AAm) was suc...
