The pilot-scale study on a sludge recycling enhanced coagulation–ultrafiltration (UF) process for surface water treatment is investigated in this paper. The impact of the sludge recycling ratio and coagulation stirring strategy on removal, sedimentation efficiency, and membrane fouling control was studied in this work. Sludge recycling ratios of 0%, 5%, 10%, 15%, and 20% were applied, and the o...

Biomass harvesting is a bottleneck in microalgae culture and microalgae-based wastewater treatment systems. Sedimentation coupled to coagulation flocculation has been experimentally studied for long time, however, full scale sedimentation experiences have not addressed so far literature, scaling up from experimental results may be straightforward. The aim of this study was evaluate the performa...

PJIHE INTRODUCTION of rapid, simple methods for measuring the specific gravity of body fluids ’ has led to a growing appreciation of the usefulness of such measurements, particularly as applied to blood and plasma.’’#{176} Although it is not difficult to measure the specific gravity of blood prior to coagulation, the comparable treatment of plasma requires special facilities for rapid sedimenta...

A dispersed-ozone flotation (DOF) separator was devised for a pilot study of tertiary wastewater treatment for re-use purposes. As a compact device combining coagulation, ozonation and flotation in an integrated unit, the DOF separator achieved a very high removal of SS, TOC, UV254 and colour, as well as effective inactivation of coliform and total bacteria within a short hydraulic retention ti...

Polymerization rates of silica at various concentrations and pHs have been studied via nephelometry. The ability and potency of ultrasonic radiation on the coagulation process in aqueous samples with and without silica colloidal particles have been extensively investigated. Factors affecting the rate and filtration volume such as silica concentration, time of radiation, temperature, and fre...

Introduction Macrophage activation syndrome (MAS) is a rare but life threatening complication of infectious, neoplastic and rheumatic diseases. Clinically, patients usually have high fever, hepatosplenomegaly, lymphadenopathy and neurologic symptoms. In laboratory results pathognomonic are pancytopenia, decline in the value of sedimentation rate (ESR), increased levels of ferritin and coagulati...

In this study, the responses of Dissolved Air Flotation (DAF), sedimentation, and sand filtration treatment processes on feed water with varied algal concentrations were investigated, based a technical–economic analysis using data collected from drinking plant (DWTP) in Guangxi, China. Cost-effective for sources algae proposed. The results showed that DAF was able to achieve almost 95% removal ...

In this work, different treatment methods for wastewater from textile washing operations in the Palestinian territories were studied. The goal of the treatment process was to enable the textile industry to reuse the wastewater in textile washing through simple, efficient, and cost-effective methodologies. Actual textile wastewater samples from local textile factories were used and were found to...
