ecoLine-A
high performance-cost effective
above ground oil water separation
Version 1.3.2.20
Page 2
Highly efficient and cost saving oil/water
seperation is today‘s challenge.
ecoLine-a is our answer
Small facilities are frequently hot spots when it comes to
treatment of hydro-carbon laden waste-water. The total
amount of wastewater generated per day is sometimes
too small to justify construction cost for the installation of
a below grade oil/water separator.
For these applications, an above grade unit provides an
acceptable solution. The ecoLine-a Oil/Water Separator
provides the first substantial cost savings in the form of
zero construction site labor.
ecoLine-a is equipped with a removable top panel. This
provides full access to all basic elements of the ecoLine-a
system. Routine cleaning and maintenance are then efficient and cost effective. Annual maintenance cost savings
range from 30% to 50% lower than that of conventional
separator systems.
Today‘s environmental legislation
is hard enough to comply with.
ecoLine-a meets tomorrow‘s standards today
It’s not just the ecoLine’s long maintenance intervals and low waste-disposal costs that make it such a
good investment, but the fact that it is designed with future standards in mind. The ecoLine-a far exceeds
the strict European standards (DIN1999 and EN858) for performance (less than 5ppm of free oil). The
outstanding independent testing certificates demonstrate that ecoLine-a will provide clean water that
exceeds today‘s environmental standards. ecoLine-a also allows for tighter, future environmental discharge
compliance guidelines to be met with little or no modification to the system. ecoLine-a combines high
efficiency oil/water separation with mobile flexibility. Specially designed coalescing media panels provide
a large specific surface to support the separation of small oil droplets. If your oil separation application is
variable with numerous holding tanks in various locations or space is too limited for a below grade unit,
consider ecoLine-a as your above grade oil/water separator.
Working Principle
The ecoLine-a oil/water separator is designed to separate non-emulsified light liquids or low-water-soluble
fluids with a specific gravity below 0.95 (gasoline, diesel, heating oils and other mineral oils) from effluent
discharge. A two-step separation process, gravity separation and removal of small oil particles by coalescing
media elements, produce high removal efficiencies.

Purification Step 1: Gravity Separation
The sediment and solids, pre-treated run-off is gravity fed or pumped (typically with a positive displacement
or diaphragm type pump) to the gravity separator through a submerged inlet pipe. The separation process
relies on the fact, that light fluids have a lower specific gravity than water and thus float on the water
surface.
Purification Step 2: Coalescing Media
In the residual oil media, fine droplets, that are too small to be separated
by gravity alone are accumulated into bigger drops that rise to the surface.
This coalescing media is made of reticular (i.e. „net-like“) soft polyurethane
foam. The media-cartridge is very easy to lift out and reinstall once it is
cleaned/rinsed with a garden hose.

Operation and Maintenance
Installation:
The separator must be installed above grade and leveled on a solid surface. The chosen
location for the system should be as close as possible to the source of waste stream to be
treated. When choosing the location, make sure that the separator can easily be accessed
for maintenance. Avoid any pipes or hydraulic structures that may contribute or increase
the amount of mechanically emulsified oil, upstream to the separator. When the influent
holding vessel requires it to be pumped, only positive displacement, diaphragm or screw
type pump should be employed to avoid extreme mechanical emulsification of oil-laden
wastewater. The system is designed for use inside a building. Avoid high temperature or exposure to
sunlight. Ensure proper venting of the system.
Maintenance:
The coalescing media cartridge has to be cleaned periodically. Since the maintenance intervals strongly
depend on the very application, check the condition of the filter element weekly during the first 60 days
of operation. The filter media can be cleaned/rinsed with a garden hose. Recycle the wash-water to the
separator.
Over time, UV radiation and sun light will degrade the coalescing media. It is, therefore, strongly
recommended that the media inside the cartridges not be left outdoors for extended periods of time after
cleaning. Some exposure to UV radiation and sunlight will not harm the system.
Remove sludge and oil from the system periodically.
Removal of accumulated oil:
Manual oil draw-off device:
The standard version of the ecoLine-a oil/water separator is equipped with
an opening (3/4” external thread) to connect a hose and valve. The manual
oil draw-off can only be operated during non-operational periods (no
influent entering the separator). the accumulated oil can be drained into an
external oil drum (not provided).
Automatic oil draw-off device:
As an option the ecoLine-a can be ordered with an automatic oil draw-off
device. This built in ADD mechanically removes accumulated light liquids
24/7 from the water surface and stores them in an external oil recipient or
oil drum. The collected oil is free of any water (99.7% pure).
For further information about the automatic oil draw-off, please see our
O&M manual for the ADD HDPE.
Temperature range of operation:
41 to 122°F (5°C to 50°C) - permanent temperature
