This paper focuses on the feasibility of septage treatment by sludge drying reed beds (SDRB). Different designs and operation conditions of SRDB pilot-scales were tested on system efficiencies such as the top filtration layer (sand or compost) and the organic load (30 and 50 kg SSm(-2)y(-1)). Results focus on the obtained performances considering sludge characteristics, filtration efficiencies,...

Recently, midge larvae, which are indicators of aquatic environmental pollution, have been detected in tap water some areas, resulting controversy. Therefore, the objective this study is to analyze behavioural features larvae sand, GAC (granular activated carbon) and GAC/sand processes, mainly operated domestic purification plants, suggest effective operating methods for larval control. In stud...

The removal of microplastic from wastewater collected a plastic recycling facility was investigated, using laboratory scale sand-filter. Wastewater samples were before and after the onsite sand-filter, for characterization different polymer types, sizes, shapes. A considerable difference in characteristics concentrations microplastics observed sand-filtration, demonstrating differences source a...

Objective: Coronary slow flow (CSF) is a phenomenon characterized by slowly flowing contrast medium through the epicardial coronary arteries during angiographic examination without detectable stenosis or obstruction. To our knowledge, the relationship between CSF and renal blood flow has not been investigated. Therefore, this study investigated the relationship between CSF and renal blood flow....

The cytokine receptor homologous (CRH) region of the murine granulocyte colony-stimulating factor (G-CSF) receptor was secreted using a Escherichia coli maltose binding protein (MBP) fusion system. The CRH region was prepared from the periplasmic fraction by G-CSF affinity column chromatography and restriction protease factor Xa digestion, and was purified to homogeneity. The purified CRH regio...

Migration-inhibitory factor (MIF) is a lymphokine that acts to localize mononuclear phagocytes (monocytes and macrophages) and perhaps to activate them. Mo cells are a human T cell leukemia virus II-infected T cell line previously shown to secrete large quantities of MIF upon stimulation with phytohemagglutinin and phorbol myristate acetate. MIF was purified from Mo cell-conditioned medium by g...

Rapid land loss in the Mississippi River Delta Plain has led to intensive efforts by state and federal agencies for finding solutions in coastal land restoration in the past decade. One of the proposed solutions includes diversion of the Mississippi River water into drowning wetland areas. Although a few recent studies have investigated flow-sediment relationships in the Lowermost Mississippi R...

Coal gasification wastewater has complex pollutant components and high COD value, contains a variety of toxic harmful substances. The treatment coal always been one the important problems in development industry China. In this paper, aiming at removal fine particle pollution wastewater, sand filtration method was used to explore changes parameters such as solid content removal, separation accur...

Artificial fill (Holocene)—Mud, sand, and gravel of varying proportions, possibly including foreign debris such as concrete, logs, timbers, or brick. Used for highway roadbeds and other construction. Thickness generally greater than 2 m. Mapped where fill substantially obscures or has altered original geologic deposit. Beach deposits (Holocene)—Soft sand, silt, and mud deposited or reworked by ...
