Bilge and wash down water
It is designed to remove:
- hydrocarbons (oil, grease, fuel, etc)
- solids (marine matter, sand, paint
flecks,
other fine suspended solids)
Oil separated is stored in a tank for
removal
Treated water is stored prior to release
Requires no chemical treatment
BALLAST WATER

Modular Wastewater Treatment …CA-mini series
Wastewater Solution
The EW CA-mini Wastewater Treatment Package, Submerged
Contact Biological Reactor, forms the aerobic biological stage of
a packaged wastewater treatment system. The CA-mini package
are available as compact packaged plants or as packaged
modular systems.
These will treat municipal or industrial wastewater to achieve
degrees of treatment, such as BOD removal, Nitrification and/or
total Nitrogen reduction and Phosphorus reduction. Packaged
Everything Water CA-mini plants are available in a range of
specifications or can be custom built.
CA-mini series is a complete wastewater treatment system in a
flexible package of modular treatment units utilizing submerged
fixed film technology. Available modules include a Solids
Separation Tank for primary solids removal, Equalization Tank
for storage and equalize wastewater, Contact Aeration Tank for
BOD reduction, and a Sedimentation Tank for separation solids.
The CA-mini Modular Wastewater Treatment System is a complete package that
utilizes individual, self-contained, modular treatment units in series for complete,
advanced wastewater treatment. In one compact train of small, non-corrosive tanks,
this system provides for both physical and biological removal of solids, organics, and
even nitrogen and phosphorous, if required. These systems are designed to be highly
Everything Water wastewater treatment packages are based on
the research and experience of Project E over the past several
years. The polyethylene tank used in treatment is
manufactured according to high-quality standards that ensure
its durability and decades of lifespan. Other components of the
system such as air blower and pumps are selected for their
efficiency.
CA-mini series an aerobic biological
treatment process which maximizes the
efficiency of the micro-organisms to
digest the organic waste.
flexible in capacity. And the “linking” nature of the design allows easy expansion for
future growth and demand.

The technology utilized in the
reactor modules was proven in
over ten years of operation in
high-strength leachate plants.
The bio-media is the same as that
used in thousands of treatment
plants worldwide. The process is
not dependent on settling and

sludge
because the biomass is fixed in
place on the structured media.
Reliable performance is assured
because of the inherent stability
of the fixed biomass.
Treatment Mechanism
1. Solids Separation Tank
This chamber will separate sediment and
grease from wastewater with digesting organic
matter and biodegradable organics by
anaerobic bacteria (microorganisms which
function in the absence of oxygen) .
2. Equalization Tank
Equalization tank will be used to store and
equalize wastewater quantity and
characteristics. Usually, wastewater does not
flow into a wastewater treatment plant at a
constant rate, the flow rate varies during a day
according to the life style. The changing
amount and strength of wastewater to be
treated makes efficient process operation
difficult and often cause problem in a
treatment system. The purpose of flow
equalization is to dampen these variations so
that the wastewater can be treated at a
constant flow rate. In this tank, submersible
pumps will be installed to control wastewater
flow rate.
media plate will digest organic matters
moreover, the aerator will add oxygen to
the tank to help bacteria work highly
efficient and to reduce undesirable odor.
In addition, the diffuser has an air
disperser in a backwash system.
In this chamber, the introduction of air
from the blower allows a sufficient amount
of oxygen to be dissolved into the
wastewater. This additional air supply
invigorates the activity of aerobic bacteria
(micro-organisms which need the
presence of oxygen to function) living on
the surface of the bio-contact medium, to
further purify the water.
4. Sedimentation and Disinfection
Tank
As the bacteria in the Contact Aeration
dies off, if falls away from the media and
is passed forward to the final
Sedimentation Chamber where it settles,
further reducing the level of suspended
solids in the final effluent.
3. Contact Aeration Tank
After the Equalization Tank, the living
organisms in the contact

What is Continuous Membrane Filtration (CMF) ?



It is the latest technology to remove any solid
particles in water.
Basically, the CMF system pumps water
through a porous plastic membrane. This
membrane has very small holes in its’ surface
and as such filters out of the water any
suspended solids. To prevent blockages and
maintain proper flow rates, the system
backwashes the membrane with its’ own
filtered water, scours the membrane surface
with air and then provides chemical rinsing.
As all this process is fully automated by using a
PLC controller, the system will continue to
process water with minimal human
involvement.
