What Are Phosphate Magnetic Particles?
Phosphonates or phosphonic acids are organic compounds containing C–PO(OH)2 or C–PO(OR)2 groups (where R = alkyl, aryl). Most phosphonates are highly water-soluble, while phosphonic acids are only sparingly soluble. Phosphonates are not volatile and are poorly soluble in organic solvents. Normally they are more efficient FRs than phosphates, but raw materials for phosphonates are more ...

Operating costs and energy demand of wastewater treatment plants in Austria: benchmarking results of the last 10 years
This work presents operating costs and energy consumption of Austrian municipal wastewater treatment plants (WWTPs) (≥10,000 PE-design capacity) that have been classified into different size groups. Different processes as well as cost elements are investigated and processes with high relevance regarding operating costs and energy consumption are identified. Furthermore, the work shows the ...

Use of anthropogenic gadolinium as a tracer for bank filtrate in drinking water wells
Knowledge of the amount of bank filtrate in raw water is crucial for drinking water suppliers using water wells in close proximity to rivers, in particular if those rivers are strongly affected by anthropogenic activities, e.g. receiving effluents from waste water treatment plants. Analysis of organic micropollutants as tracer compounds is costly and time-consuming, and results may be biased by ...

Recycling of spent filter backwash water using coagulation-assisted membrane filtration: effects of submicrometre particles on membrane flux
Membrane separation technology has been widely used for recycling of spent filter backwash water (SFBW) in water treatment plant. Membrane filtration performance is subject to characteristics of the particles in the SFBW. A bench-scale microfiltration (MF) coupled with pre-coagulation was set up to evaluate the recovery efficiency of SFBW. Effect of particle size distribution and zeta potential ...

The effect of aeration on the removal of wastewater-derived pharmaceutical residues from groundwater – a laboratory study
Several studies on waste- or drinking water treatment processes as well as on groundwater have recently shown that some pharmaceutical residues (PRs) are redox-sensitive. Hence, their (bio)degradation depends on the redox conditions prevalent in the aquifer. Groundwater, providing raw water for drinking water production, is often anoxic and aeration is a widespread treatment method applied ...

Dairy Effluent Treatment - Total Phosphorus Monitoring
Dairy Crest's Davidstow site operates a sophisticated effluent treatment plant to ensure that the local aquatic environment is protected. The treatment plant has been upgraded to keep pace with the expansion of the factory and a number of our monitoring instruments have been employed to make the operation of the plant as efficient as possible. During 2011, the Environment Agency approached Dairy ...

3 things that you can learn on the first day of ATP testing at your wastewater plant
Of all the applications that LuminUltra works with, biological wastewater may be the most complex but also offers the greatest opportunities for cost savings and overall optimization. The greatest savings tend to come through process optimization once long-term data trends have been established but the following is a list of opportunities that present themselves immediately upon starting to ...

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 ...

Rectangular vs. circular sedimentation basins
Both rectangular and circular configurations have been commonly used in sedimentation basins in both water and wastewater treatment plans. Historically, the selection of rectangular versus circular sedimentations has been based on past experience and the preference of the design engineer or design company. Initially, the water and wastewater treatment plant designs in the world were reasonably ...
