With BOD, What You See is Often Not What You Get: The Difficulty with Accurate Testing for BOD in Industrial Stormwater Runoff.
Biochemical oxygen demand (BOD) is a measure of the amount of dissolved oxygen used by microorganisms to break down organic material in a sample of water. As they do so, these microorganisms deplete the amount of dissolved oxygen in the water, which can be deadly for aquatic species like fish that rely on dissolved oxygen to live. Because of this hazard to aquatic life, BOD is considered an ...

The Coastal Brewing Company - Case Study
Situation Making beer is a water intensive process that generates wastewater high in nutrients, biological oxygen demand (BOD) and total suspended solids (TSS). Given the nature of this high strength wastewater, many breweries face discharge fees, with some even trucking wastewater offsite. The Coastal Brewing Company, a new brewery based in Forster, Australia, had to reduce BOD in its ...

Sewer Misconnection Survey - Birmingham UK - Case Study
Background STS was invited independently by the Environment Agency and Severn Trent water to carry out a series of monitoring operations in an area which had a history of issues arising from the misconnection of waste water into a “clean” surface water sewer system. Traditionally surveys of this type are carried out using contractors who are tasked to lift manhole covers along a ...

An Interview With Flying Monkeys Craft Brewery
Craft breweries can produce five to 10 litres of wastewater for every litre of beer that they package and sell. High in organic matter and suspended solids, the wastewater’s impact can be equivalent to adding another small town to a municipality’s water treatment burden. It’s also a challenge for brewers when they must pay water consumption surcharges and find ways to optimize ...

Case Study: Real-time BOD/COD monitoring increases Dairy revenue from product recovery
A dairy plant in Minnesota was reliant on daily BOD and COD grab samples for detection of product loss. This method was inadequate for proper management and the plant required a better solution to meet their needs. Real Tech provided the much-needed real-time information on cream concentration in the wastewater to allow the plant to take action when events or spills occurred and gain an overall ...

SMF4 case study 2
Sewer Misconnection Survey Date: March 2010 Location: Edgebaston Birmingham UK Purpose: To test the application of the SMF4 portable fluorimeter in the detection and quantification of organic pollution from faecal matter in Surface water Sewers. Background STS was invited independently by the Environment Agency and Severn Trent water to carry out a series of monitoring operations in an ...

River Survey Bude Cornwall UK - Case Study
STS were invited by the UK Environment Agency to conduct a survey of a small river running onto one of the bathing beaches at Bude Cornwall. The area is renowned for its clean beaches and is very popular with both families and surfers alike. There were therefore two driving factors behind ensuring that the water discharging to the beach was clean. Firstly that it met the required regulations ...

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 ...

The Dawn of a New Era: Real-Time BOD Data Case Study
In many areas of our life, manual monitoring has been replaced by automatic or online monitoring as and when the instrumentation technology has been developed; however there is one area that has fallen behind the times and has not caught up which is water quality. Many parameters are simply not possible to measure in the field or can only be done by grab sampling. In the last ten years or so we ...

Gresham Wisconsin Bio-Dome Pilot Study 2010
This article explores the results obtained from a mobile pilot unit in Gresham Wisconsin during the winter of 2010. The pilot unit was installed to October 2010 and ran through April of 2011. During the course of the study, the Bio-Dome was tested under various loading conditions and operating conditions. Samples were taken for both the influent and effluent of the lagoon. Samples were ...

Tomato Processor Pilot Bioreactor
98% Average Reduction in BOD & TSS A tomato processing facility was required by the city to reduce BOD from 4,000 ppm to 200 ppm. Integrated Engineers proposed a small scale Bioreactor to prove the effectiveness of the activated sludge process on the customer’s wastewater as well as establishing the parameters for a full scale system design. The trailer mounted bioreactor utilizes an ...

The effects of nutrient limitation (nitrogen and phosphorus) on BOD removal from post-coagulated
Pinus radiata sulfite pulp and paper mill wastewater in a baffled aerated stabilisation basin–laboratory pilot scale studyThe use of coagulation and flocculation for tertiary treatment of pulp and paper mill effluent was investigated, where the evaluation was based on the removal of nitrogen (N), phosphorus (P) and BOD from post-coagulated wastewater. The study was undertaken on laboratory scale aerobic stabilisation basins (ASB). Two post coagulated (alum) wastewaters were studied, where the BOD:N:P ratios were ...

On-site treatment of domestic wastewater using a small-scale horizontal subsurface flow constructed wetland
A small-scale horizontal subsurface flow constructed wetland, located in North Greece, was designed and constructed to treat wastewater from a single-family residence. A three-year monitoring program was undertaken to evaluate the performance of this system. The monitoring campaigns were organized every 7 days. Water quality samples were collected at the inlet, at intermediate points (i.e. at the ...
