    Reusage of old osmotic membranes

    Hello! Some days before we changed RO membranes in osmotic system, and now I have some used RO membranes (XLE-440). Maybe you know, where to use them? I think that there is rather big amount of polyamid film inside each other, and maybe i can use it, not to put them in trash? I have an idea to...

    thread164-420231 Hello! About our

    thread164-420231 Hello! About our efforts to remove silica from water. As we understood, it was a single discharge of silica in raw water. After some time silica lowers down to very little amount again. We washed the boiler with some acid solutions (mostly sulphuric and hydrofluoric) to break...

    Solution of reusage of used ion-exchange resin (not nuclear)

    thread164-421700 Hello! After many time we casually found where to give used ion-exchange resin (but this method is not applicable to all). One of our partners, who supplies us with resins, suggested to take wasted resins from our clients. They does not say what they will do with it, but I...

    Recycling of ion-exchange resin

    Hello! Adammal44, we have only one producer of ion exchange resins in Russia - Tokem (here You can see their site in English version - http://www.tokem.ru/en/). Also, as You work in nuclear industry, I think, You use nuclear grade resins, which really have bigger lifetime in rougher conditions...

    Recycling of ion-exchange resin

    Hello! No, I'm not from nuclear industry. Maybe sometimes my company will participate in water treatment for nuclear industry, as the "aerobatics" in water treatment, but now we are more simple... In our practice, after 1.5-4 years (depending on water quality) resin begins to reduce total...

    Recycling of ion-exchange resin

    bimr, adammal44, hello! Yes, I mean usual resins from softeners. Of course, resins from nuclear industry or from toxic waste treatment etc have the only one way of utilization, without recycling.

    Recycling of ion-exchange resin

    Hello! I worked on one of our client's ion-exchanging softening system (we changed the resin) recently, and thought about what to do with old ion-exchange resin. Usually, when we recharge a softener, we have about 1-2 cubic meters of old resin (this is usual volume in any middle boiler house...

    Removing silicates from

    Thank You bimr! We thought about it. As we know from practice, colloidal something (silica, as example) quickly kills the membrane's surface and causes expensive membranes changing, so it must be removed before RO (coagulation, filtration etc.). And can You recommend any anionic exchange resin...

    Removing silicates from

    Thank You! And what about anionic ion exchange module? It will cost cheaper than demineralizer. Will it remove silica? Or they are in not-ionic form?

    Hello! We have Clack V3030-01 multicontroller for 2-6 valves. We need to change the measure unit system from american (gallons) to metric (liters), but in the instruction we've read that it was possible to do only in the first switch on. But we switched it on to check, when we bought it, an we...
