Optimum Conditions for Use:
Histosol performs within a pH range of 3.0 to 11.6 with the optimum
near pH 7.0. Effective temperature range is 40 to 145 F.
Storage and Handling:
No special handling precautions. Should be protected against long
periods of frost or freezing, thaw out before using. Suggested
maximum in plant storage is 12 months.
Application
HISTOSOL OP-9840SB can be used to control odors from sewage plants,
waste collection facilities, paper mills, and rendering operations.
In wastewater systems, it reacts with hydrogen sulfide, sulfur
dioxide and most organic acids to permanently neutralize the
chemical and its odor. 2-30 parts per million is sufficient in
most cases for odor control. The product should be metered into
the system of continuous flow streams at least 100 yards ahead
of the point of H2S release. The product can be metered directly
into waste lagoons, aeration basins, digesters, clarifiers, or
SBR's. Longer retention improves performance.
It has been found effective in removing hydrogen
sulfide and TRS gases from paper mill scrubber systems. The HISTOSOL
should be added to the circulating or make-up at the gas inlet
of the scrubber. Tests in the circulation water show neutralization
of the sulfides. Tests in the gas stream show a reduction 76%.
This
is a non-toxic and non-hazardous product. Environmental friendly.
