A novel super-cooled humidification?dehumidification system driven by thermal vapour compression unit for seawater desalination
The current study presents the concept of a novel seawater desalination system that is configured by a humidification?dehumidification unit based on the vapour-compression process (HDDTVC). The coupled refrigeration unit employs the thermal compression of vapour by a jet-ejector. The new technical idea of proposed desalination system depends mainly upon the creation of a super-cooled temperature ...

Conversion of the RAS control at the WWTP Asselbrunn to sludge level
The paper presents the effects of gradual upgrade of existing secondary clarifiers of the waste water treatment plant (WWTP) Asselbrunn. From existing two clarifiers at the beginning only one has been modified (clarifier no. 2), while the other remained unchanged (clarifier no. 1). In a first step the intake structure of clarifier no. 2 has been modified at flow proportional return activated ...

BOHS welcomes new HSE guidance as Society wins European recognition for its Welding Fume Control Selector Tool
The British Occupational Hygiene Society (BOHS) has applauded the publication of new guidance from the Health and Safety Executive (HSE) on the effective management of exposures to welding fume. In 2018 The International Agency for Research on Cancer (IARC) published a report with the reclassification of welding fume as carcinogenic to humans. Up until then it was previously thought that ...

Controlling Sludge in Lamella Clarifiers
This month we are focusing on the control of sludge blanket build up in Lamella Clarifiers. Lamella Clarifiers, also known as Inclined Plate Separators (IPS) are in common use at Waste Water Treatment Sites as small footprint plant settlement units and are often employed in place of conventional settling tanks. Controlling Sludge Blanket Build up Effluent enters the Lamella Clarifier via an ...

Algae control in SAB Miller Clarifier - Case Study
Several LG Sonic e-line devices were installed in the SAB Miller Clarifier #1 in Tocancipa Brewery, Colombia in order to control filamentous algae. The LG Sonic e-line devices were installed in the summer of 2012. The Challenge: Control Algae and Increase Process Efficiency In the summer of 2012, SAB Miller, Colombia contacted LG Sonic in order to provide a solution for the pertinent growth ...

Storm Water Pollution Prevention Plans
Why Your Railroad Facility Needs One and What to do About It Did you know that that railroad facilities are subject to the Clean Water Act? This includes requirements to have a Storm Water Pollution Prevention Plan (SWPPP) in place to clarify how you will control pollutants in storm water runoff from your facility. A SWPPP will identify the potential sources of pollution and describe the ...

Chemically enhancing primary clarifiers: model-based development of a dosing controller and full-scale implementation
Chemically enhanced primary treatment (CEPT) can be used to mitigate the adverse effect of wet weather flow on wastewater treatment processes. In particular, it can reduce the particulate pollution load to subsequent secondary unit processes, such as biofiltration, which may suffer from clogging by an overload of particulate matter. In this paper, a simple primary clarifier model able to take ...

Measuring Biochemical Oxygen Demand (BOD) Continuously in Real Time
Real-time BOD monitoring is becoming increasingly popular, and it’s no surprise as the alternative is a 5 day wait for lab results. Continuous organics monitoring opens the door for many new treatment process control and optimization possibilities that can result in significant cost savings, improved water quality, and compliance peace of mind. Information can be utilized to more effectively dose ...

Rectangular vs. Circular Clarifiers: Which is better?
Both rectangular and circular configurations have been commonly used in clarifier basins. The relative merits of the two have been discussed at length for decades. Historically, the selection of rectangular versus circular clarifiers has been based on past experience and the preference of the design engineer or design company. Initial wastewater treatment plant designs in the United States were ...
