The objective of the research was to test the effect of iron and aluminium coagulants commonly used for lake re-cultivation, on the pike sperm motility and fertilisation. The coagulants caused changes in the analyzed hydrochemical parameters of the water such as: Fe, Mg, TSS, SO4 2and Cl. Selected parameters of sperm motility: MOT, VCL, VSL, VAP, LIN were estimated using CASA. The sperm motilit...

Landfill leachate may cause environmental problems if it is not properly managed and treated. An appropriate treatment process of landfill leachate often involves a combination of physical, chemical and biological methods to obtain satisfactory results. In this study, coagulation-flocculation was proposed as a pretreatment stage of partially stabilized landfill leachate prior to submerged biolo...

The membrane bioreactor (MBR) has emerged as an efficient compact technology for municipal and industrial wastewater treatment. The major drawback impeding wider application of MBRs is membrane fouling, which significantly reduces membrane performance and lifespan, resulting in a significant increase in maintenance and operating costs. Finding sustainable membrane fouling mitigation strategies ...

Problem statement: Turbid waters, containing colloidal particles, are normally treated by coagulation-flocculation followed by clarification. Ferric chloride and alum, which are the most common types of coagulants in water treatment plants of Iran as well as many other countries, were investigated with the aim of determining their capabilities to reduce turbidity of drinking water. Turbidity wa...

Prior studies have examined the ability of Moringa oleifera (MO) seed extract, among other natural coagulants, to remove several types dyes. MO has been proven a high capacity some anionic The aim present study is explore possible use aqueous and saline extracts as biocoagulants for removal Mordant Black (MB11) from solution. Their performances were compared that aluminum sulfate (alum). To do ...

most of the water treatment plants in iran discharge their sludge to the environment whithout consideration of possible side effects. since this kind of sludge is generally considered pollutant, the sludge treatment of water industry seems to be an essential task. obviously theweight and volume of solids produced during the coagulation process are much more than other wastes of water treatment ...

Lake water getcontaminate due to the growth of population and modernization which causing problems like sewage disposal has a high-volume low-strength wastewater that can be reused for many purposes after being treated. It is crucial go through treatment improves quality where one processes involved coagulation yet using conventional coagulant leaves excess heavy metal in causes absence green c...

Heavy metal, chromium (VI) removal by coagulation using natural coagulant material was investigated in this paper. Chromium occurs naturally in the paint manufacturing industry waste water in many steps of the process. The coagulation and flocculation method is used for chromium removal from waste water using fruits of Opuntia Ficus indica, Fruits of Jatropha gossypifolia and peel of Borassus f...
