Anvendelse av granulært preparat for å hemme utvikling Application of granular preparation to inhibit development
av bakterier, alger og sopp i vannsystemer. of bacteria, algae and fungi in water systems.
Foreliggende oppfinnelse angår anvendelse av et granulært The present invention relates to the use of a granular
preparat for å hemme utvikling av bakterier, alger og sopp i vannsystemer. preparation to inhibit the development of bacteria, algae and fungi in water systems.
Det har vært kjent i mange år at 2,2'-dihydroxy-5,5'-diklor-difenylmethan er et utmerket algicid, baktericid og fungicid' middel. It has been known for many years that 2,2'-dihydroxy-5,5'-dichloro-diphenylmethane is an excellent algicidal, bactericidal and fungicidal agent.
Det har funnet utstrakt anvendelse som et mikrobicid i kjøle-systemer, hvor vann sirkuleres som den eneste komponent eller som en av komponentene. Slike kjolesystemer kan gjore bruk av varmeutvekslere (kondensatorer) eller kjolere, eller direkte kjoling med vannet eller vannblandingen, såsom ved maleoperasjoner, sponfraskillende operasjoner eller valseoperasjoner i den mekaniske industri. Anvendelsen av oljevann-emulsjoner som kjolemedium ved disse operasjoner medforer problemer med hensyn til bekjempelse av mikrobevekst. It has found extensive use as a microbicide in cooling systems, where water is circulated as the only component or as one of the components. Such dressing systems can make use of heat exchangers (condensers) or dressings, or direct dressing with the water or the water mixture, such as in grinding operations, chip separation operations or rolling operations in the mechanical industry. The use of oil-water emulsions as dressing medium in these operations entails problems with regard to combating microbial growth.
Et annet problem er tilstedeværelsen av vann i lagringstanker Another problem is the presence of water in storage tanks
som inneholder hydrocarboner, såsom brenselolje, petroleum, kerosen eller paraffin. Store mengder mikroorganismer kan utvikles i lagrings-tankene, spesielt ved grenseflaten mellom hydrocarbonet og "bunnvannet". Grunnet mangelen på oxygen kan dessuten anaerobe bakterier trives i vannskiktet, og disse kan danne korrosive avfallsprodukter som tærer på lagringstanken. which contain hydrocarbons, such as fuel oil, petroleum, kerosene or paraffin. Large amounts of microorganisms can develop in the storage tanks, especially at the interface between the hydrocarbon and the "bottom water". Due to the lack of oxygen, anaerobic bacteria can also thrive in the water layer, and these can form corrosive waste products that corrode the storage tank.
2,2'-dihydroxy-5,5'-diklor-difenylmethan har liten loselighet 2,2'-dihydroxy-5,5'-dichlorodiphenylmethane has low solubility
i vann, nemlig en opploselighet av 30 deler pr. million deler og en mettet opplosning av dette virker på mange bakterier og sopparter ikke drepende eller utryddende. For å oppnå den mikrobicide virkning har det vært nodvendig å anvende en mer opploselig form av forbindelsen, f.eks. et alkalisk salt av 2,2<1->dihydroxy-5,5'-diklor-difenylmethanet. Dette salt er vanligvis natriumsaltet ennskjont også kalium-*, lithium-eller ammoniumsaltet kan anvendes. ;Det er kjent at slike salter er meget hygroskopiske, og dessuten er deres fremstilling vanskelig og kostbar. Det er derfor vanlig praksis å benytte en opplosning av natrium-2,2'-dihydroxy-5,5'-diklor-dif enylmethan. Det vil forståes at når (a) en onsket konsentrasjon av aktivt materiale onskes i et kjølesystem hvor det sirkulerende kjolemedium kontinuerlig fjernes og erstattes, eller (b) man har å gjore med "bunnvann" som tiltar i volum i lagringstanker, må man enten fore-ta et stort antall tilsetninger av mikrobicid for å justere konsentrasjonen av 2,2'-dihydroxy-5,5'-diklor-difenylmethanet i systemer, eller tilsette mikrobicidet i en så uokonomisk og hoy startkonsentrasjon at konsentrasjonen av biocidet, til tross for svinn og fornyelse eller okning av den forurensede væske, ikke synker under det bnskede minimum. Alternativt kan man benytte kostbare mekaniske måleinnretninger for å opprettholde konsentrasjonen av mikrobicidet. For å bestemme hvorvidt tilstrekkelig meget 2,2'-dihydroxy-5,5'-diklor-difenylmethan er til-sted,e, må det utfores enten en mikrobiologisk test eller en kjemisk analyse. ;I henhold til oppfinnelsen anvendes det nå et granulært preparat inneholdende mellom 10 og 60 vekt$ fast 2,2'-dihydroxy-5,5'-diklor-dif enylmethan, mellom 10. og 50 vekt$ natriumcarbonat og mellom 20 og 60 vekt$ natriumsilikatopplosning (spesifikk vekt 1,<*>+ - 1,7) for å - hemme utvikling av bakterier, alger og sopp i vannsystemer. Det har vist seg at man ved å blande fast 2,2'-dihydroxy-5,5'-diklor-difenylmethan med kommersielt natriumcarbonat og fukte blandingen med kommer-sielt vannglass (natriumsilikat) kan man fremstille granuler som, når : de anbringes i et vandig miljb, frigjor 2,2'-dihydroxy-5>5'-diklor-dif enylmethan i slike mengder at der fåes vandige opplosninger hvor konsentrasjonen av biocidet kan variere mellom 200 og 5000.deler pr. million deler. in water, namely a solubility of 30 parts per parts per million and a saturated solution of this does not kill or eradicate many bacteria and fungal species. In order to achieve the microbicidal effect, it has been necessary to use a more soluble form of the compound, e.g. an alkaline salt of 2,2<1->dihydroxy-5,5'-dichloro-diphenylmethane. This salt is usually the sodium salt, although the potassium*, lithium or ammonium salt can also be used. It is known that such salts are very hygroscopic, and furthermore their production is difficult and expensive. It is therefore common practice to use a solution of sodium 2,2'-dihydroxy-5,5'-dichloro-diphenylmethane. It will be understood that when (a) a desired concentration of active material is desired in a cooling system where the circulating cooling medium is continuously removed and replaced, or (b) one is dealing with "bottom water" that increases in volume in storage tanks, one must either -take a large number of additions of microbicide to adjust the concentration of 2,2'-dihydroxy-5,5'-dichloro-diphenylmethane in systems, or add the microbicide in such an uneconomical and high starting concentration that the concentration of the biocide, despite loss and renewal or increase of the contaminated liquid, does not fall below the desired minimum. Alternatively, expensive mechanical measuring devices can be used to maintain the concentration of the microbicide. To determine whether a sufficient amount of 2,2'-dihydroxy-5,5'-dichlorodiphenylmethane is present, either a microbiological test or a chemical analysis must be carried out. According to the invention, a granular preparation is now used containing between 10 and 60% by weight of solid 2,2'-dihydroxy-5,5'-dichlorodiphenylmethane, between 10 and 50% by weight of sodium carbonate and between 20 and 60% by weight $ sodium silicate solution (specific gravity 1.<*>+ - 1.7) to - inhibit the development of bacteria, algae and fungi in water systems. It has been shown that by mixing solid 2,2'-dihydroxy-5,5'-dichloro-diphenylmethane with commercial sodium carbonate and wetting the mixture with commercial water glass (sodium silicate) it is possible to produce granules which, when : they are placed in an aqueous environment, releases 2,2'-dihydroxy-5>5'-dichloro-diphenylmethane in such quantities that aqueous solutions are obtained where the concentration of the biocide can vary between 200 and 5,000 parts per million parts.
Et slikt .preparat kan, når det inneholdet i en egnet utpor-sjoneringsbeholder såsom et nettingbur eller en toypose, opphenges på et passende sted i kjolesystemet eller i lagringstanken. Such a preparation can, when contained in a suitable dispensing container such as a mesh cage or a toy bag, be suspended in a suitable place in the dressing system or in the storage tank.
Utporsjoneringsbeholderen fylles deretter ganske enkelt med lengre tids mellomron, når visuell inspeksjon viser at dette er nodvendig. Dessuten kan mengden av forbrukt biocid bestemmes ved at man bestemmer forskjellen mellom den opprinnelig anvendte mengde og den gjenværende mengde. The dispensing container is then simply filled at longer intervals, when visual inspection shows that this is necessary. In addition, the amount of biocide consumed can be determined by determining the difference between the originally used amount and the remaining amount.
Mengden av 2,2•-dihydroxy-5,5'-diklor-difenylmethan kån være mellom 10 og 60 vektprosent, mens mengden av det kommersielle natrium-, carbonat kan være mellom 10 og 50 vektprosent og mengden av natrium-silikatopplosnirig mellom 20 og 60 vektprosent (spesifikk vekt 1,4 - 1,7), beregnet på preparatets vekt. Ved å variere mengdeforholdene mellom de tre komponenter kan det fremstilles granuler som gir ulike konsentrasjoner av 2,2'-dihydroxy-5,5'-diklor-difenylmethan i vann. Ved å variere torke- og blandebetingelsene kan granulenes storrelse varieres. The amount of 2,2•-dihydroxy-5,5'-dichloro-diphenylmethane can be between 10 and 60 percent by weight, while the amount of the commercial sodium carbonate can be between 10 and 50 percent by weight and the amount of sodium silicate soluble between 20 and 60 percent by weight (specific gravity 1.4 - 1.7), calculated on the weight of the preparation. By varying the proportions between the three components, granules can be produced that give different concentrations of 2,2'-dihydroxy-5,5'-dichloro-diphenylmethane in water. By varying the drying and mixing conditions, the size of the granules can be varied.
