BIOLOGICAL FILTRATION SYSTEM DESIGN
Description of Service
Oxygen transfer and biofiltration equipment requirements vary widely depending on water replacement rate, feed rate, culture-water quality targets and other factors. For example, biofilter size can vary by a factor of 10 or more based on these and other factors. The use of this service generally reduces equipment costs and prevents undersizing in systems with difficult water quality problems.
Please inspect this questionnaire to see if you are interested in this service. Information you provide in this questionnaire is processed in our exclusive "Biofilter Sizing" computer program. The program performs standard ammonia-nitrogen and oxygen mass balance analyses, incorporating animal feed energetics algorithms to determine biofiltration requirements. It is not applicable to plug-flow (raceway) or green-water (heavy algal) systems—please call the Pentair AES Technical Service Department at 407-598-1401 for assistance with these kinds of systems. Program reports enable our personnel to more accurately size ammonia removal equipment for your unique environment. Biofilter sizing is included in the "Recirculating System Design" service, so if you complete that questionnaire there is no need to fill out this Biofilter Sizing questionnaire.
The Pentair AES Biofilter Sizing program is the result of hundreds of hours of research and development by qualified personnel. Without such analysis, equipment must be sized quite conservatively (and expensively) to cover generic worst-case conditions. The service includes summary printouts of key program inputs (customer supplied), design outputs and equipment recommendations.
Please review the questionnaire. If you submit one, a representative will respond by calling you to discuss your questionnaire responses and your payment options. Call 407-886-3939 if you have questions or need additional information.
