Sewage sludge (SS) dewatering is a key step in sludge disposal, which plays an important role in reducing sludge volume, facilitating transportation and subsequent treatment. In this paper, a facile hydrothermal-alkaline treatment for SS was proposed, which can be used for sludge dewatering and humic acid (HA) recycling at the same time. …
Stabilized bromine is used for the disinfection of cooling towers and is a good choice for spas and other situations with warmer water. ... the hydrogen peroxide causes lysing of the bacteria which releases liquid from the solids and allows for more effective dewatering of the anaerobic solids. ... optimization of systems and water conservation ...

Sulzer's GT-BTX process is a result of extensive testing of extractive distillation solvents and blends. Our experience indicates that certain combinations of solvent components enhance extraction performance. Co-solvents also provide an additional parameter for the optimization of unit performance (e.g., stability, mass transfer efficiency).
Design optimization of construction dewatering has important values in protecting the surrounding environment and reducing the engineering cost. The existi …
Bromine, chemical element, a deep red noxious liquid, and a member of the halogen elements, or Group 17 of the periodic table. Natural salt deposits and brines are the main sources of bromine and its compounds. Jordan, Israel, China, and the United States are major producers of bromine.
Mechanical dewatering processes are commonly used to reduce the sludge volume; aiming at the optimization of energetic or agricultural recovery of the sludge, storage and transport. Dewatering by screw centrifuge is one of the most important and widely used operation in sludge treatment.
An efficient, green and sustainable process for bromine recovery and purification from the CBSBPs of the WPCBs smelting was proposed in this work. …

The first objective is to develop module-scale models for membrane-based technologies to accurately assess their dewatering performance for high salinity brines. The second objective is to develop process-scale cost optimization models that determine …
MGO Tutorial - Dewatering Scenario Introduction Pumping well optimization technology is used to determine the ideal pumping well locations, and ideal pumping rate s at these locations, in order to minimize or maximize a specified criteria. Typically, pumping well optimization is used in the following applications:
It was applied to bromine extraction from the brine and aqueous solution which contained trace bromide, The basic principle of the technology was that the bromine volatilized into gas between film hole and electrolyte interface when the material fluid through the membrane pores. With the driving force which caused by bromine concentration gradient
Turbidity is a simple indicator of water quality that can be measured with turbidity meters and sensors across a variety of applications. In almost all water supplies, high levels of suspended matter are unacceptable for aesthetic reasons and can interfere with chemical and biological tests. The ability to accurately and reliably measure ...
Breathing bromine gas could cause you to cough, have trouble breathing, get a headache, have irritation of your mucous membranes (inside your mouth, nose, etc.), be dizzy, or have watery eyes. Getting bromine liquid or gas on your skin could cause skin irritation and burns. Liquid bromine that touches your skin may first cause a cooling ...
With the phasing out of leaded gasoline, the bromine market contracted significantly and plants extracting bromine from seawater ceased operations.
Rolling horizon optimization for the thickening-dewatering can improve the optimization effect. This paper is organized as follows. The mineral processing plant and the stochastic chance-constrained optimization framework are described in Section 2. The feed quantity predictive model is established by GCA and PLS in Section 3.
The most commons measurement methods are as follows: Gravimetric Method: The most common technique for measuring solids, the Gravimetric Method involves trapping the solids suspended in the water sample onto the filter, using a filtering apparatus and determining the dry weight of these solids. Electrochemical: Analyzing TDS in the Lab or field ...
