    Drewplex Marine Boiler Treatment

    Unfortunately,as a relatively small steam generator, you are being sold a product that is formulated to be the "one size that fits all".This is a common marketing effort to satisfy a large group of users where each user over uses some products in the blend to gain an effective concentration of...

    Need Deaerator - oxygen removal calc

    Firstly, You should know that your deaerator is not functioning effectively... It should not produce oxygen levels above 7ppb.. I would fix the deaerator befor looking at anything else......Countryham

    requirments in boiler water treatment

    I have been challenging past methodology and thinking about oxygen scavenger applications in deaerators for a long time. Current knowledge suggests that it is advantageous to carry a 5ppb dissolved oxygen residual in deaerators and consequently all feed water equipment.Lower oxygen residuals...

    Sodium Hypochlorite vs calcium hypochlorite for water dist.

    The subject has been pretty well covered here. I have been mulling over these ideas for many years and I have never seen anyone address the improper use of available sodium hydrosulfite sources to chlorinate potable (drinking water). I don't think that anyone has addressed the fact that sodium...

    Reactor Clarifier - Out of Service

    Yes, there may be a way to do it cheaply, as I did thirty years ago... Tell me more about your water supply... High turbidity?.. Kind of chemical treatment?... Storage capacity? Residence time?

    Ferric Chloride vs Ferric Sulfate Coagulants

    I have used all three over the past thirty five years.. I have done about everything that can be done (wrong) while by making poorly assumed "educated guesses"....I have found nothing that compares to alum as a surface water coagulant but alum has at least two shortcomings.-1.It forms three...

    Demin Water on carbon steel

    The earlier responses to your message were unquestionably "on Target"... I never heard of anything like that! and I've been to a whole bunch of county fairs......There is one thing for certain that has been well researched back to the pre 1940,s............The combination of carbon dioxide and...

    Treatment of hard water with polyphosphates

    I have been building a file on phosphates for over thirty five years and I have not found one true "authority" on this subject.The generally accepted view has been in use since Calgon patented the use of hexametaphosphate in municipal water supplies many,many years ago...

    Recent FAC & Oxygen attack in boiler feedwater equipment

    Reply to Kenvlach,--Of course, I am interested in any/all systems that have a proven or highly suspected failure due to FAC in feedwaters,- especially those failures in industrial boiler economizers that are fitted with carbon steel and those ruptures generally in elbos and welds(highly impinged...

    Recent FAC & Oxygen attack in boiler feedwater equipment

    Thanks, eyec-- I have that one on file....If you have any other similar information, I would certainly like to know about it...As Artemus Ward (1834-1867) once said,--"It ain't so much the things we don't know that get us in trouble. It's the things we know that ain't so".--- Mail...

    Any More Potential Benefits of New Oxygen Scavenging Technology??

    This (tannin ) question is a real supprise!!... Have only heard of tannin used as a scavenger one time before!Tannins and/or other organic materials similar to sodiumlignosulfate to prevent sludge from becoming adherent on boiler shell surfaces----which has been in boilerwater use since the use...

    Any More Potential Benefits of New Oxygen Scavenging Technology??

    I have developed a new , greatly improved method of catalytically scavenging oxygen with sulfites from boiler feedwaters--almost instaneously (with a 4+ times greater catalytic result than ever thought possible in the past with any other (commonly accepted catalyst technology)--CONTROLLED within...

    Unknown benefits of new oxygen scavenging technology

    I have developed a new,greatly improved method of catalytically scavenging oxygen with sulfites from boiler feedwaters-- almost instaneously (with a 4+ times greater catalytic result than ever possible in the past with any other (commonly accepted catalyst)technology)----CONTROLLED within 1-2ppb...

    Recent FAC & Oxygen attack in boiler feedwater equipment

    Can anyone furnish any known recent(documented)corrosion or failures/ explosions in boiler feedwater systems, with or without injuries??I am looking for industrial boiler waterside failures that can be attributed to Flow Accelerated Corrosion in economizers and oxygen attack in either or both...

    Improving color in water

    I have been dealing with "color" issues for over thirty years and I can assure you that trying to "scrub" natural occuring colloidal color bodies in the form of tannins is very,very difficult, if not impossible.. The pulp and paper industry has worked to remove color bodies...

    Basic disinfection of potable water in 3rd world

    WITHOUT RE-STATING THE OBVIOUS NEED OF CLEANLINESS--and not becoming over technical----There is absolutely nothing wrong with the use of sodium hypochlorie if it is not made from a byproduct (spent acid) that may contain heavy metals......In any case, all benefits of bleach far outweigh the...

    Water Treatment - Flocculation

    I realize that you have to start from "somewhere"... however, any design you attempt ,if it is to be effective on in any system must be relative to the unique system parameters, i. e.---In order to do this --it requires hundreds ,if not thousands of hours at the bench........Rapid...
