If you have witnessed one or two cycles of the market you probably know what we are talking about, the cycle of excitement, hope, and disappointment when the market goes up and down. But what convinces me to stay in the market while my portfolio’s value falls below 30%?!

Well, I think we should step back a little and change our perspective. look at the cryptocurrency market, what is it? where is it going? does it seem to be collapsing? or is it like a baby who falls, gets up, and grows day by day?

We have the opportunity to experience the latest technology which seems to probably change all the economic structure in the near future! such a big movement will not be an easy way to go, but the rewards will be tremendous too, for people who are the earliest funders of this movement!

So don’t get worried! just stop looking at your portfolio for a week, and start to learn about the projects, to see how fantastic the cryptocurrency world is! we are like people who tried to experience computers 40 years ago! This would be a new era, and you are a part of it!

The Post Treatment of Leachate with a Combination of Microwave and Persulfate Processes

For a long period of time, disposal of municipal and industrial wastes has been a major concern of human societies. Landfilling, composting and incineration are common ways to eliminate these wastes. Although modern landfills have been prepared by high-tech facilities to minimize the risk of waste, the problem of large quantities of polluted leachate has still remained. Landfill leachate is defined as high polluted wastewater containing a wide range of organic and inorganic contaminants. This study focused on post-treatment of landfill leachate by using Persulfate alone (PS alone) and Microwave-persulfate (MW-PS) integrated processes. The effect of initial pH, reaction temperature, Sodium Persulfate concentration, Microwave power, and reaction time was investigated on the removal of organic load and color of the leachate. According to the results, the effect of initial pH on the reaction was negligible in both used systems. As the temperature rose in the range of 40˚C to 95˚C, significant growth in the removal of Color and COD occurred in both processes. Increasing the concentration of Sodium Persulfate up to 30g/L and 35g/L, respectively for PS alone and MW-PS integrated processes have resulted in an increase in COD removal. In MW-SPS, the higher power of MW favored COD removal and energy consumption. During the persulfate alone process, after 4 hours, at pH=9, T=80˚C, and in the presence of 30g/L sodium persulfate, the maximum COD and color removal efficiency of 82% and 100% were achieved respectively. Based on the results of the experiments, in MW-PS process the maximum COD and color removal efficiency of 88% and 100% were also achieved respectively, after 4 hours, at pH=9, T=80˚C, and in the presence of 35g/L sodium persulfate. In the studied processes, pH decreased during the reaction and dropped from 9 to 1.8 and 1.6 for PS alone and MW-PS processes, respectively, in optimized conditions. In the MW-PS integrated process, leachate EC increased from 32S/m to 72S/m and turbidity decreased from 19.5NTU to 6.0NTU. A kinetic study shows that the order of reaction was 1.42 for MW-PS and 1.81 for PS alone process. Despite the increase in COD removal and energy efficiency in presence of MW irradiation, the results of this study indicate that COD and TS of effluent have not met the standards for discharge into the environment.
