Investigates anaerobic twostage treatment of tannery wastewater. This results in a mean chemical oxygen demand (COD) removal of 60 per cent for tannery B and more than 70 per cent for tanneries A and C with CODo = 5,710mg l–1 and mean detention time held at 3.5 days. Gas production was small, rating an estimated 75l kg–1 CODo with CODo = 5,710mg l–1. Tests simultaneously the influence of qualit...

BACKGROUND Several medicaments have been used to devitalize remaining pulp or maintain pulp vitality and promote healing. Based on pulpal biocompatibility and good sealing ability, a growing interest in more biocompatible materials promotes mineral trioxide aggregate (MTA) as an alternative to traditional medicaments. Uniquely, MTA can preserve pulpal health predictably and promote healing with...

Abstract Removal of pollutants produced by industrial plants requires reusing water and access to the environment standard. The chemical coagulation process is a convectional method for wastewater treatment reduce oxygen demand total suspend solids. objective this work study effect initial pH, coagulant type, dosage used on separation performance at different oil concentrations. Based result, 8...

ONE OF the first professional groups to study the Negro in America was the medical doctor. His conclusions, therefore, are a necessary adjunct to any analysis of American concepts of race and attitudes of racial inferiority. Racial attitudes, clothed in the authority of medical science, helped to suggest, justify, and dictate biological as well as social categories; indeed, medical science help...

Catalytic oxidation of spent sulfidic caustic consist SH- ion or NaHS compound by H 2 O2 in neutral acidic solution to elemental sulphur may provide a convenient and economical method for the control sulphide wastes their associated odors at pulp, paper textile industry. Oxidation sulfide rayon waste hydrogen peroxide was investigated presence ferric sulfate catalyst. Kinetic equations activati...

Background and Aims: Altering dietary ferrous sulphate (FS) consumption exacerbates a murine model of colitis alters the intestinal microbiome. We investigated impact oral ferric maltol (FM) FS on mice with dextran sodium (DSS) induced colitis, microbiome patients iron deficiency. Methods: Mice had acute induced, 2% DSS for 5 days, followed by water. During this period, groups were fed standard...

In this work, the recovery of Cu from large waste printed circuit board (PCB) pieces by biogenic ferric sulphate at high solid to liquid ratio was studied. PCB parts were packed in a column and constantly recirculated. A oxidation reduction potential (ORP) decrease observed leaching due ion consumption; drop caused slower copper dissolution kinetics. After 25 days, 62.2% leached PCBs column. co...

Surface water pollution has increased, owing to industrial development and population growth. Consequently, it is important find alternative drinking treatment strategies, which cater for changes in the quality of raw water. This study compared efficiency different coagulants treating that feeds a plant (WTP). Using jar testing equipment number physicochemical parameters, an investigation was c...
