Understanding Algal Blooms and Eutrophication: A Growing Environmental Concern
The process by which water bodies, enriched by excessive nutrients, experience algal blooms is known as eutrophication. While some algal blooms are harmless, others harm both aquatic life and humans, due to the toxins they produce. Furthermore, after the algae die, they sink to the bottom of the water body, where bacteria and other microorganisms begin decomposing them, consuming oxygen in the ...

Managing phosphorus levels to prevent algae blooms
When phosphorus levels in a water body reach abnormally high amounts, it can severely disrupt natural cycles and trigger a chain reaction of ecological imbalances. Rapidly multiplying organisms such as algae can benefit the most from this excess of nutrients. If not dealt with promptly, these algae can form large, unsightly, and potentially toxic algal blooms, known as harmful algal blooms ...

Phosphate Monitoring at Effluent Keeps Costs Down and Levels In Check
Overview After studies indicated a need for additional phosphorous treatment, this plant placed a colorimetric water analyzer at the point of effluent to inform chemical dosing. Challenge The wastewater treatment plant for the City of Madison, IN, averages about two million gallons per day and oversees about 50 lift stations, for a population of approximately 16,000. A staff of 12 handles plant ...

Nitrate Biosensor - Case Study
BACKGROUND In 1998, Dr. Bill Campbell and his team published a peer-reviewed journal article in Analytical Chemistry on the construction and characterization of Nitrate Reductase-Based Amperometric Electrode and Nitrate Assay of Fertilizers and Drinking Water. This publication set the stage for the nitrate biosensor project. In this publication, we found that nitrate reductase was indeed capable ...

mini LoP improved performance - Case Study
Meeting very stringent total phosphorous requirements is a challenge for a treatment plant that is receiving wastewater from a dairy process. With a total phosphorous limit less than 100 ppb, a reliable, precise, highly accurate ortho-phosphorous measurement is required to monitor and control the tertiary phosphorous removal process. Small town plants in the upper Midwest commonly encounter this ...

Scanning success - Case Study
Scanning Success: A multiparameter analyzer helps a Kentucky treatment plant step up to the plate and meet a new phosphorus limit in its permit In 2001, the Lexington Fayette Urban County Government West Hickman Creek Wastewater Treatment Plant in Nicholasville, Ky., was starting Phase II of its third upgrade since 1972, when the state imposed a phosphorus limit. Total phosphorus hovered around ...

River conservation is ‘blind’ without high-resolution monitoring
Scientists from the University of Portsmouth have been investigating nutrient concentrations in the Upper River Itchen, in Hampshire, UK, on behalf of Salmon & Trout Conservation (S&TC) to better understand where phosphorus is coming from and how it is impacting river ecology. The work has been ongoing for over three years and Lauren Mattingley, Science Officer for S&TC says: ...

Characterization and biodegradability of sludge from a high rate A-stage contact tank and B-stage membrane bioreactor of a pilot-scale AB system treating municipal wastewaters
In light of global warming mitigation efforts, increasing sludge disposal costs, and need for reduction in the carbon footprint of wastewater treatment plants, innovation in treatment technology has been tailored towards energy self-sufficiency. The AB process is a promising technology for achieving maximal energy recovery from wastewaters with minimum energy expenditure and therefore ...

Reuse of effluent discharged from tannery wastewater treatment plants by powdered activated carbon and ultrafiltration combined reverse osmosis system
We evaluate the applicability of a reverse osmosis (RO) system that combines powdered activated carbon (PAC) and ultrafiltration (UF) to treat the effluent discharged from tannery wastewater treatment plants. Conventional treatment processes such as neutralization, clariflocculation, and biological processes are used to clean the effluent before feeding to the PAC and UF combined RO system. ...

Power Industry: Noxious Fumes at TVA Handled by Scrubber - Case Study
To keep the work area free of noxious fumes and reduce atmosphere pollution, T.V.A. Wilson Dam uses a 36″ diameter Clean Air Group fume scrubber to handle 12,500 cfm of gas @ 150°F in their high-analysis super phosphate operations. Manufacturing high analysis super phosphate fertilizer at the TVA Wilson Dam operation creates noxious fumes. Most of these fumes are liberated during the ...

A GIS-based spatiotemporal study of the variability of water quality in the Dubai Creek, UAE
This paper presents the outcomes of a study on the water quality of Dubai Creek which aimed to assess its eutrophication status. Field water quality data from stations along the creek collected in 2012 and 2013 were used. Ordinary least squares (OLS) and spatial autocorrelation analyses were used as part of geographic information system (GIS)-based exploratory regression analysis to study the ...

Performance evaluation of wastewater treatment using horizontal subsurface flow constructed wetlands optimized by micro-aeration and substrate selection
The effects of micro-aeration and substrate selection on domestic sewage treatment performance were explored using three pairs (with or without micro-aeration) of horizontal subsurface flow (HSSF) constructed wetlands (CWs) filled with zeolite, ceramsite or quartz granules. The individual and combined effects of micro-aeration and substrate selection on the purification performance of the ...
