INTRODUCTION

The PC4® biological plant with technology MBBR consists in a compact system plug-and-play
solution type thought for the domestic or industrial waste water treatment.
The biological treatment applied is an advanced process of Moving Bed Biofilm Reactor (MBBR)
with different compartments including (anoxic chamber, biological reactor and lamella settling). The
moving bed is a technology based on the development of specific microorganisms growth on a fix
inert support, the carriers.
This is an advanced alternative technology economically advantaged in front of the conventional
activated sludge systems. The average performance of the MBBR biological systems is higher than
95% for the DBO5, DQO, SS, N and P removal.
The basic concept of the installation is to operate inside
normalized containers of ISO dimensions, which
facilitates its transport and installation anywhere in the
world
The container can be adapted to resist harsh climate and
the hardness of the waste water to be treated.
SYSTEM ELEMENTS

The compact pre-treatment consists in different normalized modules in ISO dimensions and includes
the following elements:
Prefabricated inlet pumping
station of the entering waste water
to the preliminary treatment.
Compact preliminary treatment consists in a fine
screening to remove the solids coming with the inlet raw
water.

Biological reactor that can be designed in 1,
2 or 3 chambers depending on the treatment
required for each case.
Plastic carriers of high specific internal
surface and size.
Lamella settler. Advanced high performance
unit to separate suspended solids
SYSTEM ELEMENTS
Electrical equipment and instrumentation
for flow rate, ORP and dissolved oxygen
measurement in real time.
Control system and PLC + SCADA, with
Touch Screen and telecontrol through 3G /
GSM/ GPRS remote acces

The compact plant has a monoblock structure of
welded steel.
Internal compartments are made of PRFV panels with
mechanic reinforcements of orthophthalic resin and a
chemical protector barrier of vinylesther resin which
gives more strength.
CORNERSEC system avoids any possible
loss of water between panel unions.
11
STRUCTURE
The structure realizes full integration of structural
and mechanical elements and includes a
footbridge giving access to all of them.
For the installation in the plant the requirements are
leveling of the ground and civil engineering work
on a concrete slab.
The unit is completely ready for the
outdoor installation. When installing it into
extreme climates, we offer the possibility to
cover its upper side and it is also possible the
thermal insulating of walls.
STRUCTURE
12
The projected system consists in a moving bed biological process with extended aeration in
MBBR or IFAS configuration.
Biological reactor is easy to set in 1, 2 or 3 chambers depending on the needs of each client.
Chambers will operate independently and each individual working conditions are adjusted to obtain
the desired treatment results.
BIOLOGICAL REACTOR

Biological chamber
In each chamber is developed one specific microorganism
growth which helps to decompose the organic materials and this
way is obtained a high quality of treated water.
The configurable processing variables in each chamber
depending on the process needs are the following ones:
• Mixing power.
• Aeration.
• Type of carriers
(depending on its specific surface) .
• Percentage and density of the filling media.
The working conditions in each chamber are totally controlled by
probes and are easily adjustable from the control panel.
BIOLOGICAL REACTOR
14
Their function is to enable the growth of specific microorganisms attached
over a surface so, this way we achieve higher biomass concentration
comparing to the MLSS processes.
This treatment substantially reduces the volume required and therefore
the surface needed for the treatment and achieves a higher level of
elimination rate of DBO5 and nutrients.
PLASTIC CARRIERS
The type of plastic carriers are selected to obtain the optimal density of microorganisms and to
achieve the desired treatment results in the most efficient way.
Its design and operation characteristics enable the process to achieve a performance superior to
95% of organic matter removal and supports much better the peak of pollution loads.
The design of the support is unique and its characteristics are:
• High efficiency and high specific internal surface.
• Inert material resistant to corrosion and chemical attack.
• Low costs per surface unit.16
The biofilm consists of a solid and a
liquid matrix where volumetric split of
liquid matrix represents about 80% of its
volume.
The solid matrix is formed by
heterotrophic bacteria, nitrifying
bacteria, biodegradable DQO and inert
DQO.
The liquid matrix consists of water and
soluble components, such as ammonia,
oxygen or nitrates. The gradient of
concentration of these components on the
surface of the biofilm draw as a result a
stratification of bacteria of the solid
matrix attached on the plastic support .
