The water treatment plant (WTP) employs a variety of electrical machines and utilities, making it an intensive energy consumption plant. In this study, audit was conducted on the Basbari WTP in Kathmandu, Nepal to identify hotspots that consume most recommend solutions for energy-efficient operation. A power quality analyzer used analyze patterns parameters data from electricity authority. stud...

Rheinheimera sp. strain SA_1 is an iron-depositing bacterium for which we report a draft genome sequence. Strain SA_1 was isolated from iron backwash sludge of a waterworks in Germany. The Illumina MiSeq technique was used to sequence the genome of the strain.

We evaluated the efficiency of five membrane filters for recovery of Cryptosporidium parvum oocysts and Giardia lamblia cysts. These filters included the Pall Life Sciences Envirochek (EC) standard filtration and Envirochek high-volume (EC-HV) membrane filters, the Millipore flatbed membrane filter, the Sartorius flatbed membrane filter (SMF), and the Filta-Max (FM) depth filter. Distilled and ...

In this study, the use of backwash, extracted from city waste from Tehran's Kahrizakareawasinvestigated in agricultural applications as well as in eco system applications. The purpose of thisresearch was to definethe quality of qualitative and quantitative parameters to measure the output ofleachate treatment plant Arad Kooh(Kahrizak Tehran) in order to reuse it for agricultural use anddischarg...

Several innovative filtration technologies have been developed in the last two decades to decrease the backwash requirements, to increase the water production efficiency, and to improve the operational and design conditions. The Compressible Medium Filter (CMF) also known as the “Fuzzy Filter” involves the use of a synthetic compressible fiber (polyvaniladene) porous material as the filtering m...

The coquina clam, Donax variabilis, rides flow from waves, migrating shoreward during rising tides and seaward during falling tides. This method of locomotion, swash-riding, is controlled not only behaviorally but also morphologically. The shape of this clam causes it to orient passively; a clam rotates in flow, usually in backwash, until its anterior end is upstream. Rotation is about a vertic...

Abstract Microcoagulation has recently been considered as a promising pretreatment for an ultrafiltration (UF) process from numerous studies. To investigate the effects of microcoagulation on performance UF–reverse osmosis (RO) system treating wastewater with high and fluctuant salinity, different dosages coagulant (poly-aluminum chloride) were added prior to UF unit in pilot-scale UF–RO 10-wee...
