摘要:
Method for reducing or inhibiting increase in microbial concentration in a water-based fluid and formulation for reducing or inhibiting increase in microbial concentration in a water-based fluid or system The present invention provides methods and formulations for reducing or inhibiting increase in microbial concentration. concentration of microbes in a water-based fluid. the methods and formulations of the present invention utilize glutaraldehyde and a hydroxymethyl substituted phosphorus compound selected from the group consisting of tetracis (hydroxymethyl) phosphonium salts, C1-3 alkyl and alkenyltris (hydroxymethyl) phosphonium and tris (hydroxymethyl) phosphine salts, in a ratio of hydroxymethyl substituted phosphorus compound to glutaraldehyde in the range from about 2: 1 to about 7: 1 or from about 3.5: 1 to about 7.5: 1. The methods and formulations of the present invention may be useful in treating water contaminated with aerobic or anaerobic bacteria in oilfield, natural gas field and other industrial applications.método para reduzir ou inibir o aumento na concentração de micróbios num fluido à base de água e formulação para reduzir ou inibir aumento na concentração de micróbios num fluido ou sistema à base de água a presente invenção provê métodos e formulações para reduzir ou inibir o aumento na concentração de micróbios num fluido à base de água. os métodos e formulações da presente invenção utilizam glutaraldeído e um composto de fósforo substituído com hidroximetila, selecionado do grupo consistindo de sais de tetracis(hidroximetil) fosfônio, alquila c1-c3 e sais de alqueniltris (hidroximetil)fosfônio e tris(hidroximetil) fosfina, numa relação de composto de fósforo substituído com hidroximetila para glutaraldeído na faixa de cerca de 2:1 a cerca de 7:1 ou de cerca de 3,5:1 a cerca de 7,5:1. os métodos e formulações da presente invenção podem ser úteis no tratamento de água contaminada com bactérias aeróbicas ou anaeróbicas em campo petrolífero, camp
