This study is a numerical study on the coagulation as well as the sedimentation effect of nanofluids using the Brownian dynamics method. Three cases are simulated, focusing on the effects of the sizes, volume fraction, and ζ potentials of nano-particles on the formation of coagulation and sedimentation of nanofluids. The rms fluctuation of the particle number concentration, as well as the flatn...

The article is devoted to a problem of sedimentation of superfine aerosols with a characteristic size of particles, an order of values of micrometers. Acceleration of the sedimentation process is promoted by imposing of an acoustic field that leads to acceleration of coagulation of particles. Besides, pressure of the sound radiation directed down, accelerates gravitational sedimentation of an a...

Spatio-temporal distributions of stratospheric aerosols, measured by the ORA instrument from August 1992 until May 1993, are presented in the latitude range (40◦ S–40◦ N). Particle total number density, mode radius and distribution width are derived and interpreted. The respective roles of advection, sedimentation and coagulation are discussed. We also identify clear transport/sedimentation pat...

The dataset presented in this article are related to the research article entitled "Hybrid coagulation-UF processes for spent filter backwash water treatment: a comparison studies for PAFCl and FeCl3 as a pre-treatment" (Ebrahimi et al., 2017) [1]. This article reports the cost estimation for treating produced spent filter backwash water (SFBW) during water treatment in Isfahan- Iran by various...

The current study analyses the performance of deep sand filtration of greywater from an office building and the performance of a combined physicochemical process comprising of coagulation, sedimentation and filtration. Raw greywater quality exhibited very high variability with average turbidity of 35 NTU, and TSS, COD(t), and BOD of 45, 240, 75 mg/l respectively. The stand-alone filter removed ...

INTRODUCTION Today, the pneumatic tube transport system (PTS) is used frequently because of its advantages related to timing and speed. However, the impact of various types of PTS on blood components is unknown. The aim of this study was to examine the influence of PTS on the quality of routine blood cell counts, erythrocyte sedimentation, and certain blood coagulation tests. MATERIALS AND ME...

in order to decrease the discharge from sulfide mine flotation plants, treatment and reuse approaches based on our previous wastewater monitoring experiments were explored in these plants. the flotation wastewater was collected from the case plant and was treated with coagulation sedimentation and activated carbon adsorption. then, the effluent was examined for reuse in the flotation process. f...

Abstract The research aim was to analyze the optimum dosage of moringa seed and tamarind as an organic coagulant in removing tofu wastewater pollutants using coagulation, flocculation, sedimentation reactors. first step is manufacture by processing raw materials into powder filtered a 50 mesh filter dried. second determine 4 variations pH 5,6,7,8 NaOH solution, dosages obtained 2,3,4,5 gr/L. th...

The city of Bekasi is experiencing rapid development so the demand for water increasing. To increase service coverage and meet drinking needs people City with a quality that meets Minister Health Regulation No. 492 2010, it planned to up rate capacity Teluk Buyung 4 WTP has 300 L/second raw source, namely West Tarum Secondary Channel. use design criteria from Equivalent evaluation, 3 literature...

The aim of the study was to estimate effectiveness ultrasonic coagulation aiding. effect ultrasound exposure alone and associated systems (ultrasound exposure/coagulant) on contamination natural water examined. evaluation test results based changes in indicators, such as TOC, color, turbidity, electrokinetic potential. Three different coagulants were used tests systems. included basic processes...
