Aquacide QLF is a non-oxidizing
biocide formulated for the control of bacteria, algae and fungi
in recirculating industrial water cooling systems, evaporative
condensers and air wash systems. Can also be added to refrigeration
drip and condensate trays to control algae and bacterial growth.Aquacide
QLF is a broad spectrum microbiocide which has exceptional effectiveness
against bacteria and fungi as well as controlling algae.
Aquacide QLF controls anaerobic sulphate-reducers and aerobic
heterotrophic bacteria in oil field and petrochemical water
injection systems.in application Aquacide QLF is effective and
stable over a broad pH range of 6.0 to 10.0. Aquacide QLF has
low foam characteristics and so there is no need to add antifoam.
FEEDING:
Aquacide QLF may be metered, pumped, gravity fed or poured from
a suitable container into the treatment system. Centrifugal,
injection, piston or diaphragm pumps are satisfactory. Algaecide
feed pumps, metres and feed lines may be stainless steel, neoprene,
glass, plastic or unpigmented fiberglass. Aquacide QLF works
best when it is applied intermittently via a chemical metering
pump actuated by a microprocessor or percentage timer.
DOSAGE:
a) Recirculating water cooling towers Initial treatment: To
a visually clean system or when algae or slime is first visible,
to sump water near pump suction, add 400 mls to 800 mls of Aquacide
QLF for each 10,000 litres of water (400 to 800 PPM) in the
system. Repeat initial dose at day intervals until algae and
slime control is evident. Badly fouled systems should be cleaned
before initial treatment. Once control is
achieved then the dose can be reduced to 300 to 600 ppm applied
every 7 to 14 days as needed. Aquacide QLF is persistent over
several days when added to a cooling tower, however the amount
of bleed-off will reduce the concentration of Algaecide QLF
and this should be considered when determining the dose frequency.
Upon discharge the concentration
of Algaecide QLF will be reduced below the MIC level and this
will enable biodegradation of the product.
Intermittent Doses: to prevent
a clean system from fouling, slug doses may be applied intermittently.
The frequency of intermittence will vary with individual systems
and can be established through experience. Intermittent doses
may be required 2 to 3 times a week in some systems. Other systems
may require dosing once a week or once every 2 weeks. For heterotrophic
bacteria use 200 to 800 ppm Aquacide QLF. For anaerobic sulphate
reducers, use 60 to 230 ppm Aquacide QLF. Maintain these doses
for 2 to 8 hours, depending upon the requirements of your system.
Continuous Treatment: Fouled systems should be slug treated
to get initial control, followed by continuous treatment to
maintain control. Use 60 to 200 ppm Aquacide QLF. The lower
dose concentration is usually satisfactory for Desulfovibrio.
Higher doses may be needed for the aerobic heterotrophic bacteria.
