It’s been a long road—we spent a year building the architecture to be able to construct the app itself. Our designers have tools to explore product visions that are not currently possible to build, making it the engineering team’s job to figure it out…not just how to make any implementation, but to build one that is incredibly fast, smooth, and polished. Consistently, for every feature. Environment- Toughest in last 10 year. They asked limit of impurities from water quality, asked from filtration (Tough to understand the question even forget about answer), one 2 marks tricky question from air pollution, No question from BOD,Noise,MSW,Hardness, Sedimentation. They entirely skipped the important topics.
Yes it is a profitable business. I purchased 1 machine from Jai Durge Industries, Jaipur, Rajasthan and started working on it as part time. Service and machine both were upto the mark. I made so much profit that I purchased 4 more machines and now work full time in this business. But be aware of fraud as most of the machine sellers promise for an agreement for buyback in order to sell the machines. Please dont fall for this type of shit as it isn’t possible. Well It depends. If you just need a tag that I also have a publication then there are too many paid journals available now a days. But remind you nobody gives a damn about these journals. It better not to have a publication rather then having one in those crappy journals.
