    Boiler blowdown flash vapor recuperation.

    Hello, In our factory we have two 13,000 lbs/hr boilers, the blowdown goes into a flash tank, and there the vapor goes to the athmosphere, is it possible to recover this vapor? One of the engineerings in the factory saids that it isn't possible, because it's low pressure steam, and that we...

    Excess of RO water production

    Thanks for your answers, I talked with my RO contractor, and he didn't want to cycle the system based on water demand. Because he says that his membranes will get damaged, and that he will have to sanitize the equipment every time it gets stopped. I would like to run the RO system (It...

    Excess of RO water production

    Hello everybody, In our plant we have a 80-85 gpm Reverse Osmosis Unit (Supplied by a contractor that charges us for that consumption, even if we didn’t use it), but in average we are just consuming 55 gpm. We have two 60 m3 tanks for heating and storing the water. Since the RO can’t be stopped...

    URGENT - Save water in cooling towers

    Hi, as I commented on my last thread (thread164-111386) I want to improve my cooling towers. Currently we are running at an extremely low 1.66 concentration cycles… We use deep well water, and we chemically treat it with Sulfuric Acid, Biocide, Hipoclorite and multifunctional chemical. But we...

    Increase Cooling Towers Concentration Cycles

    Well, thanks very much for your responses. I have contacted an engineering firm, and they suggested me and Ion Exchange System for treating the rejects from: - Cooling Towers - Reverse Osmosis - Boilers . Softeners regeneration They are talking about removing 95-98% of the hardness of the...

    RO Water use in Boilers

    Thanks for your answers, TBP: We have condensates return, but anyways, we are feeding 55 m3/day to our boilers (19,800 m3/yr). We didn't know the amount of blowdown... Can somebody aproximate the amount of blowdown that we could have? We recirculate part of the blowdown to the condensates...

    RO Water use in Boilers

    Thanks for your answers, EdStainless: Teh conductivity is so high because the water that enters to the 2nd RO unit, is the reject from the 1st one, so that water has a conductivity of 3000 microsiemens. The boilers purge when water reaches a conductivity of 3000 microsiemens... Are there...

    RO Water use in Boilers

    Hello, I'm José Isita, an engineer from Mexico. In the plant we have 2 RO Units, the first unit produces permeated water that we use in our product, and the second, treat the reject from the first unit for reusing it in other areas of the plant. Since this water is softened and has lower...

    Treat make-up or blowdown water in cooling towers.

    Thanks for your responses, more info about this, is in my other post about Cooling Towers. Really do you think is better to treat the make-up than the blow down? (In order to save the biggest amount of water) What's more typically done? I want to increase the concentration cycles…. Because...

    Increase Cooling Towers Concentration Cycles

    Thanks very much for your responses... In addition we have an unused Reverso Osmosis unit (We used it before replacing it by a newer one). Do you think that it could be cost effective to use it for treating the blowdown of the cooling towers? Also, if you can gave me an approximation of the...

    Treat make-up or blowdown water in cooling towers.

    Good morning, I’m going to install a water treatment system for our cooling towers, but I didn’t know what will have bigger water savings, to treat the make-up water or to treat the blow down in order to re-use it. Any ideas in what will be better? Thanks

    Increase Cooling Towers Concentration Cycles

    Hi, I am a Mechanical Engineering from Mexico. I am responsible for water savings projects in the plant. One of the biggest opportunities areas that I saw is in the cooling towers. We have two towers with the following characteristics. Tower # 1 Tower # 2 Water...
