OPERATION GADGETS
By Thomas Higgins
Assistant Operator, Industrial Waste Treatment Plant, Lederle Laboratories Division, American Cyanamid Company, Pearl Biver, N. Y.
Lederle Laboratories Division of
American Cyanamid Company is lo cated in Pearl River, N. Y., about 30
miles north of New York City. The
wastes of this biological and pharma ceutical plant and their method of
treatment have been described in This
Journal, 23, 8, 1017 (Aug., 1951).
Briefly, pretreatment of the industrial wastes by pre-aeration and high-rate
trickling filters in the company's own
industrial waste treatment plant ac

counts for a B.O.D. reduction of 80 per cent prior to discharge to the town
sewage treatment plant for ultimate
disposal to a small stream.
Several gadgets have been developed
by the writer to aid in operation of the
industrial treatment plant. Some of
these are described, with the thought that they might prove useful to other
operators.
An ordinary kitchen fork can be
modified by cutting of the two outside
tines and bending the remaining two
tines at right angles to form a hook

(see Figure 1). This tool has been
found to work very well in cleaning
openings on rotary distributors (see
Figure 2). It can also be used on
stationary nozzles, in removing pack
ing from pumps, and for a number of
other useful purposes.
Weir Cleaner
A common household dustpan can be
made into a very useful gadget, par
ticularly where clarifiers are employed. Perforations are made in the base of
the pan to allow water or effluent to
drain through. A piece of sheet metal
approximately 3 in. high and long
enough to extend about 4 in. in front of the pan is attached to the off side
(see Figure 3) to prevent the objects
scraped from the clarifier weirs from
being swept into the effluent trough. The pan itself is covered with ^-in. wire mesh attached by %-in. bolts
through holes drilled in the sides of the
pan. The unit, completed by attaching an old broom handle, has been found
extremely helpful in cleaning clarifier
wTeirs of leaves and other clogging mate
rials. When filled, the collector can
be dumped into a convenient container.
(Operation of the weir cleaner in the
manner shown is, however, not recom
mended because of the hazard of falling into the clarifier tank from the slippery
weir apron.?Ed.)
Another helpful hint in good house
keeping is the use of automobile-type waxes on chlorine machines. A dusting once in awhile is all that is required after the first application and the sur
face resists most rust and corrosion.
