...and ideal for industrial processes!
The AVC system is ideal for dewatering waste water produced
in many industrial processes. The AVC has in practice proven
that it is an excellent choice for dewatering of sludge from a
palm oil mill to fly ash from cooling towers.
Whether it's to service routine contracts or industrial processes
the AVC system delivers substantial savings in disposal and
transport costs as well as a lower environmental impact.

Product description for the AVC...
The AVC consists of a closed container, equipped inside with
filtration screens along the two sides and a filtration screen down
the centre. The filtration screens drain and de‐water the
flocculated sludge. The rear of the container is equipped with a full
width door with a hydraulically assisted locking mechanism,
through which the de‐watered sludge is emptied.
The front of the container is equipped with a filler pipe through
which the container is charged with sludge.
A pivoting galvanized ladder is mounted at the front of the
container and when drawn down erects a galvanized safety rail
which allows easy and safe access to the top, where the inspection
hatches are located.
The cleansed water is discharged through two 3" ball valves, one on
each side. The container is equipped with an inside ladder for easy
access for cleaning and inspection. The container is sandblasted,
primed and painted. The inside surface is coated with epoxy.
The AVC has been sold to more than 20 countries around the world.
We believe that the successful expansion of the brand is attributed
to a highly motivated work force who constantly strives for
perfection. We can deliver the AVC & DOD/EOD in a construction
where the EOD/DOD is integrated into the AVC dewatering
container, so it becomes one unit. This is a perfect solution for
stationary system is placed permanently at one location etc

Recycling of dewatered sludge...
There are several routes for recycling and disposing of the
dewatered cake from the AVC system. Depending on the specific
nature of the dewatered cake it can either be lime stabilized and
used as fertilizer on agricultural land, composted or used in
biogas plants. With our brand of lime/sludge mixing plant
dewatered sludge is mixed with lime.
The pH level is raised to 14 and you obtain the optimum
temperature of approximately 80° C. This gives an effective
sanitation and delivers a log 6 reduction in pathogens.
Grease or contaminated cakes can be used to accelerate the
burning process at incineration plants or as a last resort be
deposited at a landfill site. In addition to the fact that we
construct effective sludge dewatering systems it is also one of
our strengths that we and our partners are able, through the
contracting division of the company, to offer advice and technical
support in the handling of sludge's from the knowledge and
experience gained over many years.

Pasito Kenya Ltd., with technical collaboration with
her European partners is proud to introduce for the
first time in East Africa their equipment for the wet
waste industry. In particular our own series of jet‐
vacs and not to mention the well‐known mobile
and stationary units for the effective dewatering
and treatment of sludge's. We boast of 75% export
share, spread over three continents.
The major part of our research and design
programme, is to produce state of the art products
for the industry, tailored to our customers'
requirements.
Due to our customers' satisfaction guarantee
policy, we have repeat orders of 95% from all our
customers.
90 % volume reduction and 95 % reduction of COD and BOD ‐
only a few of the advantages of the AVC & EOD/DOD system!
It dewaters the sludge to a dry mass with various recycling
possibilities!
...a guaranteed investment
for the future...
The AVC system is the most economical and
efficient product and fits the global environmental
strategy because it reduces waste volumes by up to
90%. In many cases, the dry filter cake produced
can be safely disposed off at a licensed landfill site
or recycled and used as fertilizer after a controlled
sanitation process to name but a couple of routes.
It's simple to operate...
Realising that the average sludge contained a high
percentage of water, which was needlessly being
transported for disposal at the local waste water
treatment works, we have decided to develop a
system that would take the treatment works to the
sludge and that was the reason the AVC & DOD/EOD
came into existence.
The principle behind the AVC & EOD/DOD system is to deliver a
high "volume reduction" of sludge.
The EOD/DOD is a pumping and polymer dosing unit. EOD is the
electrical driven construction and the DOD is a diesel engine
version.
The EOD/DOD pumps the sludge into the AVC dewatering
container where the separation of the water and dry matter
occurs.
The EOD/DOD unit is used to mix polymer into the sludge as it is
being pumped into the AVC de‐watering container. Mixing of
polymer into the sludge creates a flocculation that increases the
speed and efficiency of the de‐watering process.
Under normal circumstances the sludge is drawn into the
EOD/DOD by the sludge pump located on the EOD/DOD and then
polymer is injected automatically at a suitable amount by the
polymer pump and the injection system of the EOD/DOD.
The user can easily regulate the actual amount of polymer
injected by adjusting the speed of the polymer pump. Easy to
operate!
The sludge can also be delivered directly into the EOD/DOD from a
pressurised tanker, where the polymer is then injected into a
Cyclone system attached to the EOD/DOD. This function is
particularly useful if the sludge contains crude debris such as
stones, heavy sand and metal etc. which would normally damage
the sludge pump. The flocculated sludge continues from the
cyclone and in to the AVC where separation of water and dry
matter occurs.
AVC translated means, on‐site dewatering container. The AVC is a
dewatering unit constructed as a mobile container. The AVC
consists of a closed container, equipped inside with filtration
screens. The filtration screens drain and de‐water the flocculated
sludge. The front of the AVC is equipped with a filler pipe through
which the container is charged with sludge. The reject water is
discharged through valves on the front of the AVC. The rear of the
AVC container is equipped with a full width door, through which
the de‐watered sludge is emptied.
