container to hold the processed water. Subsequent
water processing requires only diatomaceous earth
(DE), chlorine, and fuel.
The major components of the system are shown in
figure 2-26. This mobile water purification unit
contains a diesel-powered pumping module, a control
and chlorination module, a filter module, supplies, and
components mounted within a protective frame. It is
supported on a pair of skids. Each module may be
operated independently in or out of the frame because
the interconnections and external connections use the
same cam-locking devices. The unit may or may not be
mounted on a trailer. The 3000-D can be set up and
operated by one person, and it requires no support
The power for the system is supplied by an air-
cooled diesel engine to take advantage of a greater fuel
supply in the field.
A highly durable bronze pump, directly linked to
the engine, provides both the suction to draw in the
untreated water and to provide the water pressure to the
unit. The 3000-D Water Purification System is
designed to be transported to remote sites on its own
optional trailer, on the back of a compact pickup truck,
or air-lifted by helicopter with its own standard sling.
SETUP.-At the site, the system should be located
on a level area located as close to the water source as
possible to reduce suction lift to a minimum. For best
results, the system should be located not more than 15
feet above the liquid supply. The suction line should be
as short as possible and have few bends to keep friction
losses low. The system is usually placed within 30 feet
