The preparation method of zirconia powder
1. Co-precipitation method The co-precipitation method is currently the most commonly used method for preparing nano-zirconia due to its simple operation, easy control of the reaction process, and low cost. The specific process of this method is: adding some stabilizers (such as Y(NO3)3) and dispersing agents (such as PEG2000, etc.) to make soluble zirconium salts (ZrOCl2·8H2O, ZrCl4 or ...

The harm of ammonia gas and the treatment principle of ammonia gas scrubber
Ammonia is the most abundant alkaline gas in the atmospheric environment and plays an important role in the atmospheric environment and ecosystem. On the one hand, ammonia gas can promote the formation of sulfate and nitrate and increase the concentration of fine particulate matter (PM2.5) in the atmosphere, and on the other hand, it can neutralize atmospheric acidic substances and reduce the ...

Improved Bioretention & Nitrogen Removal with Natural Zeolite
Soil amended with clinoptilolite zeolite is shown to increase the removal of nitrogen and other toxins from wastewater, while improving the water holding capacity and cation exchange capacity. In most places water that enters a storm drain will go directly to a local body of water, it generally does not get treated at a wastewater plant. That means all those toxic pollutants that are swept away ...

Wastewater Is An Asset | It contains nutrients, energy and precious metals
People think as little as possible about the wastewater that is produced daily from their showers, bathtubs, sinks, dishwashers and toilets. But with the right techniques, it can become a valuable resource. On average, every Americans uses about 60 gallons of water per day for purposes that include flushing toilets, showering and doing laundry. This figure can easily double if outdoor uses, ...

Innovation, Speed and Proven Technology Secured Success for Piney Point Remediation Project
Overview When Nclear was called in to treat 250 million gallons of wastewater following a breach at the defunct Piney Point phosphate plant, they needed the right tools, including their own technologies for phosphorous and ammonia removal and the Aqua TROLL 500 for easy and accurate water quality monitoring. Challenge In March 2021, at the former Piney Point phosphate plant in Manatee County, ...

Product introduction of ammonia adsorption scrubber
The ammonia adsorption scrubber is mainly used to treat the ammonia tail gas volatilized from the exhaust port at the top of the ammonia water storage tank, the ammonia water dosing box and the ammonia water metering box. The principle of absorption achieves the purpose of purifying and absorbing ammonia gas. The material of the ammonia scrubber body is PP polypropylene. The influent water is tap ...

Nitrous Oxide 300 Times More Harmful than Carbon Dioxide
Wastewater treatment choices can reduce emissions of the potent greenhouse gas The harmful effects of carbon dioxide on the atmosphere are well known, but another greenhouse gas, nitrous oxide, does considerably more damage to the environment. Many human activities, including wastewater treatment, release nitrous oxide into the atmosphere. This is particularly alarming in light of a 2020 study ...

Organic Nitrogen in treated sewage
Being pioneers meant that we didn't have many answers, but this allowed us to improvise as we go along. Imagination, and passion were the only limitations, and there were no rules. The beauty of this industry (package treatment plants) is that we (the industry) are the 'Wright Brothers' of sewage treatment. Whilst things have changed since the old pioneering days when Scarab was just an ...

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 ...

What is Shortcut Nitrogen Removal?
This streamlined process, used in Fluence’s Nitro plants, lets you deal with high-load sidestreams efficiently Two common goals for wastewater treatment plants are nitrogen removal and energy neutrality, but in traditional biological treatment processes, the energy requirements for mixing and aeration are high. Carbon and chemicals to control pH levels also are required. The shortcut ...

Membrane inlet mass spectrometry method (REOX/MIMS) to measure 15N-nitrate in isotope-enrichment experiments
Using 15N stable isotope as a tracer to quantify N transformation rates in isotope-enrichment experiments improves understanding of the N cycle in various ecosystems. However, measuring 15N-nitrate (15NO3–) in small volumes of water for these experiments is a major challenge due to the inconvenience of preparing samples by traditional techniques. Lin et al. (2021) developed a ...

How do Wastewater Treatment Plants Transform in the Era of Carbon Neutrality?
In November 2019, the Danish government signed a "Danish climate partnership" with 13 business representatives, which basically covers the greenhouse gas emissions of all industries in Denmark. The members of the Climate Partnership need to provide emission reduction recommendations in their respective fields to help the Danish government realize its 2030 commitment-that is, Denmark’s ...
