Use of Waste-to-Energy Sludge Growing in Europe
This byproduct of anaerobic digestion is fertilizing fields and helping divert waste from landfills Anaerobic digestion (AD) is an important waste-to-energy technology that harvests energy — in the form of biogas — from organic pollutants in wastewater and solid waste. Anaerobic digestion is ideal for challenging wastewater streams that might cause significant public health risk if ...

42% solids reduction in industrial lagoon system - Case Study
Drylet was tasked with applying its solution to a facility that was experiencing difficulties with breaking down accumulated solids in its wastewater lagoons system, compromising performance. The covered anaerobic lagoons had become walkable as if paved with concrete, while flaring had dropped from 12 to 2 hours daily. Mechanical dredging would have destroyed the established AD ecosystem in the ...

The danger of formaldehyde on the health of professionals
Formaldehyde, more commonly known as formalin, is an aqueous solution present as a colorless gas with a pungent odor. This gas was considered a carcinogen of category 1 and was added to the list of carcinogenic substances in the order of 5 January 1993. Indeed the danger of formaldehyde is an element to take more and more seriously in the indoor air. It is ubiquitous in both home and business ...

Bore Scope, Borascope, Bore-Scope or Borescope?
You may say, “I went on Google and tried to search for a Borascope but didn’t find what needed.” Well, the truth is that this visual inspection device has a few different spellings that will offer differing results. In fact, the singular spelling of BORESCOPE may offer different results than the plural form Borescope. Admittedly, a borescope may not be something that the average ...

Top Applications of Shortcut Nitrogen Removal
Skipping a step streamlines treatment of a range of high-ammonia wastewater sidestreams Over the years there has been an ongoing quest to make wastewater nutrient removal more efficient than traditional activated sludge treatment, which is effective but uses a great deal of energy, carbon, and oxygen. There has been progress, starting with full nitrification-denitrification and simultaneous ...

Biogas and the Food and Beverage Industry
Food and beverage operations are ideally positioned to enter the circular economy with waste-to-energy systems The food and beverage (F&B) industry is known for its high-load wastewater. In general, it’s estimated that wastewater sent to treatment utilities contains five times the energy needed to treat it, but the streams from F&B operations are often laden with fat, oil, and ...

Speciation of five arsenic compounds in urine by HPLC/ICP-MS
High-performance liquid chromatography (HPLC) coupled to an ICP-MS has become an invaluable analytical tool for the determinations of trace levels of individual arsenic compounds (speciation). Speciation of arsenic is used to improve our knowledge of arsenic’s biochemical interactions and to evaluate toxicity risks. The toxicity and bioavailability of arsenic is highly dependent on form or ...

Treating organic waste with Cambi® THP
This paper describes how the Cambi Thermal Hydrolysis Process (THP) treats biodegradable organic waste and converts it to renewable energy and pathogen-free and bio-fertilizer. The interest for the process is expected to increase due to new environmental legislation as well as increasing demand for renewable energy. The implementation of the European Landfill Directive 1999/31EC and the Animal-by ...

Going further with food: The rise of channelling food waste for biogas production
Almost 50% of the total amount of food thrown away in the UK comes from our homes, representing over seven million tonnes of food and drink wasted from British households annually. Wasting this food costs the average household £470 a year. In fact, if we all stop wasting food that could have been eaten, the benefit to the planet would be the equivalent of taking 1 in 4 cars off the road ...
