INTRODUCTION
A WORD ABOUT YOUR DELTA
ADVANCED WASTEWATER TREATMENT
SYSTEM AND HOW IT WORKS
The ECOPOD-N Fixed Film Wastewater Treatment System
™
that you have purchased produces high quality water suitable
for various disposal methods. It is used to enhance your on-site
wastewater disposal system. You can be proud that in purchasing
your ECOPOD-N Fixed Film Wastewater Treatment System
™
and with a minimum amount of maintenance, you can directly
contribute to a cleaner, safer environment.
All wastewater treatment systems of this type work by using
the bacteria that nature has provided. By pumping air into the
system, the bacteria grow and thrive in much larger amounts than
would occur naturally. The over population of bacteria speeds
up the process of breaking down domestic wastewater, making it
safe for release into the environment. This entire process takes
place within the walls of your specially designed, self-contained
ECOPOD-N Fixed Film Wastewater Treatment System.
™
The result of this process is a clear, odorless discharge, which
meets or exceeds state water quality standards.
By following the few simple steps that you find in this manual, your
ECOPOD-N Fixed Film Wastewater Treatment System will provide
™
you with years of service and the knowledge that you are doing
your part to protect public health, our ground water, lakes, rivers,
and streams.
The ECOPOD-N ™ Fixed Film Wastewater Treatment System
may be only one of several components required by your health
department to provide a complete on-site system.
ECOPOD-N DESCRIPTION
™
Wastewater enters a pretreatment/settling tank similar to
conventional septic tanks. In this tank, debris and settleable
solids settle to the bottom and are decomposed by anaerobic
bacteria.
The effluent leaves the pretreatment tank and enters the
ECOPOD-N Fixed Film Wastewater Treatment System reactor
™
tank, where it is introduced to an oxygen-rich environment. In
this oxygen rich environment, a colony of bacteria, called the
biomass, develops and is capable of digesting (breaking down)
biodegradable waste into carbon dioxide and water. This is a
continuous process as long as the biomass is supplied with
incoming wastewater and oxygen. The ECOPOD -N
Wastewater Treatment System is a specially designed containment
device that houses an engineered plastic media specifically
designed to treat domestic wastewater. The engineered plastic
media has a 19mm sheet spacing with a total surface area of 47
square feet/cubic feet of media pack. The ECOPOD -N
Film Wastewater Treatment System is submerged in a tank of
liquid, which operates as a dilution/recirculation clarifier zone.
An external air compressor is connected to the tank to provide
the necessary air to the system. There are no moving mechanical
parts or filters in the ECOPOD -N
Treatment System.
In this system, conditions are favorable only to attached growth
bacteria. This means that the most common disadvantages of
other types of systems are eliminated. No rising sludge, floating
sludge or washouts can occur.
In addition to CBOD and TSS reduction, ammonia nitrogen is
one of the contaminants reduced by the ECOPOD-N
Film Wastewater Treatment System Nitrification of the ammonia
and denitrification of nitrates occur within the bacteria masses.
Complete nitrification occurs in the reactor zone, as the liquid is
recirculated in the tank, the nitrates flow through the anoxic zone
where they come into contact with the carbon source present in
the sludge at the bottom of the tank. The nitrate is stripped of
the oxygen molecule converting the nitrate to nitrogen gas. A
50%+ removal rate of total nitrogen is common without any type
of recirculation or cycling of the blower.
Fecal Coliforms are yet another constituent of domestic
wastewater that, when reduced, are indicative of the overall
pathogen reduction performance of the treatment system. The
ECOPOD-N Fixed Film Wastewater Treatment System is capable
™
of reducing fecal coliforms to under 30,000 counts per 100ml.
By following the few simple steps that you find in this manual, your
ECOPOD-N Fixed Film Wastewater Treatment System will provide
™
you with years of service and the knowledge that you are doing
your part to protect public health, our ground water, lakes, rivers,
and streams.
