Background & Aims of the Study: The wastewater created as a result of stone cutting industries enters some pools for re-consumption so that its suspended solids settle by gravity. By taking to account the high volume of water and sludge, treatment of wastewater and removal of sludge cause many problems for stone cutting units. The objective of this study was to determine the quality of wast...

There is no access to basic sanitation for half the world's population, leading Socioeconomic issues, such as scarcity of drinking water and spread diseases. In this way, it vital importance develop management technologies relevant target population. addition, in separation form treatment, compound often used a coagulant treatment aluminum sulfate, which provides good results raw turbidity colo...

This study applied a filter press for dewatering that uses pressure to reduce the water content of sludge generated in sewage treatment plants and evaluated improvement dewaterability under various coagulation conditions according type coagulants, amounts, pH conditions. The was by measurement time (TTF), change zeta potential, cake after dewatering. It found conditions, inorganic coagulants we...

colloids are small suspended particles in water which can not be settled or removed naturally due to their light weight and stability. these particles pose some degree of stability and cause water turbidity. there are some concerns regarding colloid removal efficiency in water treatment plants of iran. in this study, the effectiveness of aluminium sulfate and poly-aluminum chloride was evaluate...

Coagulation and flocculation are commonly used in water wastewater treatment. Despite its high effectiveness, utilization of inorganic metal salts as coagulant flocculant might cause negative impact to the environment human health. As an alternative tackle this problem, use natural coagulants aids is suggested. In study we reported gelatinized durian starch aid treat synthetic Congo red wastewa...

It is an important criterion the choice of lighting technique for industrial applications in water purification. In article it was examined research methods coagulation and flocculation process. Today, improvement these techniques use flocculants coagulants, which speed up process flocculation, are relevant. were considered as coagulants sulfuric acid salts Al2(SO4)3 FeSO4. noted advantage over...

INTRODUCTION Different immunoglobulin manufacturing processes may influence its effectiveness for Kawasaki disease. However, nationwide studies with longitudinal follow-up are still lacking. The aim of this study was to evaluate the comparative effectiveness of immunoglobulin preparations from a nationwide perspective. MATERIALS AND METHODS This is a nationwide retrospective cohort study with...
