Diatoms for assessing the ecological condition of inland freshwater bodies
The ecological responses of diatoms to pollution and nutrient enrichment, caused by domestic and municipal sewage, in the five fresh water ponds have been examined. It was observed that diatoms were completely absent in P3 and some species were also absent in P1 and P2. Similarly, diatom diversity was lower in P1 and P2 than in P4 and P5. However, diatom abundance was higher in P4. The Biological ...

Modeling the Praia dos Ingleses submarine outfall, Florianópolis, Santa Catarina, Brazil
An outfall 1,800 m long was initially proposed by CASAN (Water and Sanitation Company of Santa Catarina) to dispose of treated domestic residual water effluent from Praia dos Ingleses beach. The final plan average flow, estimated for the summer season is 0.1543 m³/s. The characteristics on the near field of the diffuser were calculated using the NRFIELD model supplied by a series of ...

Sewer Level Monitoring System - a case study
Background - The business of sewage level monitoring in sewers is accelerating across many countries. Strict regulations, the need to avoid environmental disasters, violation fines, early warnings and planning needs are just some of the forces shaping this growing trend. Challenges Quantifying sewage flow and level is one of the most challenging engineering tasks for the instrumentation ...

Extended CSO control storage: what could possibly go wrong?
The Thames Tideway Tunnel (TTT), is one of the main components of the London Tideway Improvements Programme, designed to capture combined sewer overflows (CSOs) which currently discharge untreated combined sewage into the tidal river Thames. CSO discharges would be stored in the tunnel until there is capacity at Beckton sewage treatment works (STW), to accept, for treatment, pumped sewage ...

Tracking biological pollution sources using PCR-DGGE technology at Ta-An Beach
The environmental authority of Taiwan has announced that ocean quality standard A, with E. coli less than 1,000 CFU/100 mL is safe for swimming. Ta-An Beach in central Taiwan was found to have exceeded 1,000 CFU/100 mL, which is 51% of the total monitoring records. Sewage, piggery and duck wastewater are discharged directly into this area. The traditional pollution source trace methods did not ...

AVFM 5.0 area-velocity flow meter monitors sewage lagoon discharge flow - Case Study
The Township of South Glengarry in Eastern Ontario discharges continuously from their 72,000 m3 sewage lagoon. But they ran into flow measurement problems when their magnetic flowmeter was unable to detect seasonal low flow rates. Operations Manager, Shawn Killoran selected a Greyline AVFM 5.0 Area-Velocity Flow Monitor because it was simple to install in a horizontal discharge pipe from the ...

Near-infrared spectroscopic assessment of contamination level of sewage
We examined the use of near infrared (NIR) spectroscopy as a rapid technique for the evaluation of sewage quality. Influent water samples, primary sedimentation tank water samples, and final effluent water samples were collected from sewage treatment facilities in Nagoya, Japan and their NIR spectra obtained. Partial least squares (PLS) models for total phosphate (TP), total nitrogen (TN), ...

IQ spectral sensors to measure Color continuously
Applications The application areas of the new color sensors are monitoring in the outlet of the sewage treatment plant and monitoring of surface waters . Methods The sensors measure according to the method DIN EN ISO 7887:2011, method C and according to the method APHA 2120 2018 (Hazen), method C. In both cases, these are methods for measurement in the laboratory. In the case of DIN EN ISO ...

Function of SO2 gas leak detector
Summary: Sulfur dioxide (SO2) is a colorless transparent gas, is a toxic gas with a pungent odor. Can accelerate the corrosion process of most metals. In the presence of PM2.5, sulfite is dissolved in the solution, under which conditions sulfite is oxidized and then converted to sulfuric acid. In the traditional sense, this is the origin of acid rain. China is the world’s largest producer and ...

Dissolved oxygen levels: a key measure of aquatic environmental health
What is dissolved oxygen? Dissolved oxygen is oxygen dissolved in water that can be aerated or diffused into the surrounding air. It is also a waste product produced by plants through photosynthesis. To keep fish and other life healthy, they must get the right amount of dissolved oxygen. If the health of the aquatic environment deteriorates, it can lead to lower levels of dissolved oxygen, which ...

Monitoring sewage sludge AD for Southern Water - Case Study
To check sludge AD, Southern Water uses portable biogas analysers specially developed for AD biogas and based on proven methane and associated gas analysis equipment from Geotech. Southern Water has an important routine; every single day it checks the health of its sewage sludge anaerobic digesters on eighteen sites across Hampshire, IoW, Sussex and Kent. There, each day Southern Water treats ...
