Hi all. Can anybody tell me: Can the washing stages use ordinary tap water or do they necessarily require distilled water?
I might try to run a recycling program for used oil in the city. Many restaurants sell it at around 15 cents/lt (probably reused as second quelity oil for cheap chinese restaurants and other places), but distilled water increases costs deamatically if I am to make batches of up to 200 liters and plan to use the bubble wash method. Does free chlorine in the water bring any problems? "Buying" the used oil already makes things expensive, and the pretended volumes of WVO aren«t big enough to reach wholesale prices for methanol (Retail methanol costs about 2.5 pesos/lt... imagine it were equivalent to 2.5 dollars/lt, which it is not.. but as salaries and cost of living have not changed since the 1peso = 1 dollar times last year, you can assume no devaluation just to picture the price in terms of % of a salary. If I had saved dollars, that would roughly be 60 cents of a dollar per liter). To consider myself in business, at least for small scale production (the intention is to sell the BD... cheaper than dino diesel of course), I need to be very careful with costs, and that includes my source of water.
