Complete Recirculation Systems
Centralised Filtration: Choosing the Correct Filtration Package
Centralised recirculating filtration systems are designed to achieve a stable environment resulting in
optimum livestock health and growth.The overall concept has been developed over many years,
through constant research and practical application.The concept is based on systematically filtering
the water using a series of mechanical, biological and chemical processes before delivering each
individual livestock tank with an independent supply of clear, UV-treated water.
Apart from a high level of animal success, each of our systems will achieve excellent levels of
cosmetic acceptance, coupled with a low labour requirement, and they can be installed within a few
hours.With the use of nitrifying bacteria cultures the biological filter matures faster and the system
can be up to full capacity within 8-10 days (depending on temperature and stocking levels), three
times faster than normal.
The design of each system follows a series of disciplines controlling flow rates and filter capacities,
proportioned to the biological demands, including eventual population fluctuations, that are typical of
a wide range of commercial applications.
However, although a good centralised system will improve the overall result, it should never be seen
as a substitute for good fish husbandry. It will surely make a good fishkeeper a better one but is
unlikely to make a bad fishkeeper a good one!
System packages have been designed with as much flexibility as possible. Modifications and
expansions are easy to achieve according to your own specific requirements and application.
The particular size and type of filtration package for a given application will depend on a number of
factors including, but not limited to, the type of livestock being held, the total stocking density, the
amount of food that is added to the system and the temperature of the water. To decide which size
system your application will require, please use the tables below.
These figures are an approximate overview of the filtration capacity of a standard System 5000.
