As a hazardous waste, water pickling liquors must be properly treated. An alternative consists of promoting the formation ferrous salts from this residue due to their higher content. Since FeCl2·4H2O is widely used in several applications, obtaining pure crystals material appears an interesting prospect. However, compound has scarcely been investigated. In present work, were obtained liquors. T...
Fluorspar is considered a critical raw material for the European Union, due to its industrial uses and lack of sufficient extraction in countries. It source hydrofluoric acid manufacture, this latter chemical being employed, among other uses, pickling stainless steels. From activity, sludge generated need used water treatment. In article, we report full characterization residue, obtained an pla...
Curing is the first process of skin treatment mainly using sodium chloride salt to prevent its decay. At soaking step tannery, effluents will be discharged environment, which contains ion, negatively affect our environment. Therefore, it should either treated or reused so that can help reduce amount ion effluent environment and cost pickling. This study focused on recycling curing for sheepskin...
Waste iron sulfate is produced in titanium dioxide manufacture and in steel pickling with sulfuric acid. Many processes have been proposed to use this waste as a source of chemicals or raw materials. The process developed here is based on the reaction with pure or waste calcium chloride (Solvay brine) to obtain iron(I1) chloride and gypsum as a b y product. The iron chloride solution can either...
The composition of pickling cucumbers varied with fruit size, which affected buffer capacity, sugar utilization, terminal pH, and texture of the fermented fruit. We found that as cucumber size increased (from less than 27 to 51 mm in dia), malic acid, pH, buffer capacity, and dry matter content decreased, and glucose and fructose contents increased. Fruit firmness and bloater damage were greate...
Twenty provinces in northeastern Thailand were investigated for fluke metacercariae contamination in pickled fish, or pla-som, during January –June 2016. A total of 129 pickled fish shops were randomly chosen. Samples were digested with acid-pepsin and those found to be infected with metacercariae were fed to hamsters to test for metacercariae infectivity. The results demonstrated that only 20....
While development of a software system is important, it is also very important to have suitable mechanisms for actually deploying code. Current state-of-the-art deployment approaches force the developer to structure the code in such a way that deployment is possible, thereby severely inhibiting reuse and comprehensibility of the system. This paper presents parcels, an atomic deployment mechanis...
