A bacterium designated Pseudonocardia sp. strain ENV478 was isolated by enrichment culturing on tetrahydrofuran (THF) and was screened to determine its ability to degrade a range of ether pollutants. After growth on THF, strain ENV478 degraded THF (63 mg/h/g total suspended solids [TSS]), 1,4-dioxane (21 mg/h/g TSS), 1,3-dioxolane (19 mg/h/g TSS), bis-2-chloroethylether (BCEE) (12 mg/h/g TSS), ...

Concentrations of chlorophyll-a (Chl-a) and total suspended solids (TSS) are significant parameters used to assess water quality. The objective of this study is to establish a quantitative model for estimating the Chl-a and the TSS concentrations in irrigation ponds in Higashihiroshima, Japan, using field hyperspectral measurements and statistical analysis. Field experiments were conducted in s...

--------------------------------------------------------ABSTRACT----------------------------------------------------------Pilot plant composed of fabric filters integrated with the decentralized treatment plant ZECUwas tested for its ability to remove the suspended solids and organic matters presented as TSS, CODt and CODs from wastewater. The filters were made from scrim polyester non-woven fa...

Background: Wastewater produced by a dairy in Sanandaj is a major source of environmental pollution threatening the city. The dairy uses activated sludge treatment to remove organic pollution from the wastewater. The present study evaluated the performance of this process and its compliance with national requirements for chemical oxygen demand (COD), biochemical oxygen demand (BOD), and total s...

Background & Aims of the Study: Anaerobic baffled reactor (ABR) is one low-cost wastewater treatment systems; however, it has some limitations, such as insufficient standard nutrient outflow. Accordingly, should be studied and developed. This research aims to determine efficiency a five-sectional pilot upgrade with an integrated aerated media filter in (integrated reactor) for municipal tre...

growing the water consuming and shortage of available fresh water resources, make “effluent reuse” an unavoidable issue in industry for supplying a part of needs for required water. on the other hand, increment in the production of paper products from wood and recycling their consumed products which release pollutants to the environment has increased the environmental concerns. thus, in present...

Environmental monitoring through the method of traditional ship sampling is time consuming and requires a high survey cost. This study uses an empirical model, based on actual water quality of total suspended solids (TSS) measurements from the Penang Strait, Malaysia to predict TSS based on optical properties of (Thailand Earth Observation System) THEOS satellite digital imagery. The proposed a...

there are many potential sources of stormwater pollutants in urban areas; one of these sources is gas stations, which are numerous and spread city-wide. a study was conducted to evaluate the water quality of runoff from gas stations in the city of tijuana, mexico. pollutant loads in runoff from gas stations in the study area were higher than in other published studies. the estimated loads from ...

The efficacy of a laboratory electrocoagulation (EC) system for treating egg processing plant waste-water (WW) is reported. For simulated and industrial egg processing WW, chemical oxygen demand, turbidity, and total suspended solids (TSS) were reduced 92 to 97%, 97%, and 99%, respectively, after treatment with EC. The final TSS concentration and turbidity values were 30 mg/L and 5 formazin tur...
