1-Ton holding capacity aquaBiota Unit with closed REBF Module
The
aquaBiota Habitat™ can be serviced by two types
of water-reuse modules: the SEMI-OPEN module and the
CLOSED REBF™ module.
• The
aquaBiota Habitat™ with SEMI-OPEN module
— This module is ideal for you
if your installation has access to enough cold seawater
to refresh the aquaBiota Habitat™
several times in a day — on, or very close to
the waterfront. While this is a
lower-cost choice, it nevertheless gives you full
control over the required rate of
refreshment and oxygen level in each tray without
the need for a biofiltration capability. A chilling
unit can be added to cool water
at critical periods of time, such as when the product
is about to be delivered.
• The
aquaBiota Habitat™ with CLOSED REBF™
— This module is the option for
you if:-
• Your distribution plant is far from
a source of seawater — perhaps servicing a large
inland urban distribution centre.
• You find yourself in a situation in
which you need to keep your animals chilled without
disturbance over periods of several months.
The CLOSED
REBF™ module is designed for
full water reuse and complete control over operating
conditions, ensuring that the water remains crystal
clear and well balanced chemically. The effluent is
passed through a seven-stage water filtration process:
two stages of particle filtration down to 15µm,
followed by a further five stages: carbon dioxide
degassing; biofiltration; oxygenation; pH control;
and foam fractionation. Note that the biofiltration
stage is carried out by Our AquaNit™ trickling
biofilters. These biofilters are delivered pre-coated
with active seawater nitrifying bacteria. This pre-coating
feature — exclusive to Aquabiotech — kick
starts the process of lowering the ammonia level in
the recycled water to acceptable levels — a
tremendous timesaver in the commissioning process.
The minimal water refreshment rate
in the system (99.9% water reuse by flow) allows for
the economical use of seawater trucked in or made
up from salt mix. The high rate of water recirculation
means that the chilling costs can be kept to a minimum.
With this system, you can be sure that your lobster
storage will give you a service equal to any seaside
operation using our Habitat with SEMI-OPEN Modules.
