PENTAIR

They Started with a Brewery Built in the 1890’s

The Historic Business and Landmark had fallen into Disrepair

PENTAIR

• Create a Fish and Plant Production Systems within the City

• Existing Building Provides Advantages of Lower Capital Costs & Subsidies for Redevelopment

• Create a System that Produces Fish and Plants at Rates to meet our Market Demand

Goals for this Project

Take Unproductive Urban Structures and Make I Productive Again

Making Abandoned This

Into Productive This

Blending RAS and AquaPonics:: Engineering Flexibility Into Fish & Plant ProductionPlant

PENTAIR

Started by Adding Infrastructure

A New Well for a Consistent Source of High Quality Water with High Alkalinity

Dependable Power with a Favorable Rate Structure

Updated and Modern Access

Newly Added Water, Power and Site Access Blending RAS and AquaPonics:: Engineering Flexibility Into Fish & Plant ProductionPlant

PENTAIR

Created the Design: Linked RAS to a Plant Growing System

Designing a system that would fit within the walls and between the columns

PENTAIR

Poly-tanks fitted with EcoTraps with Sludge Collectors & External Stand Pipes

Design Detail: 12.5 m3 tanks with EcoTrap 110 Particle Traps

• Each Tank has a EcoTrap 110 Particle

Trap, a Sludge Collector and external Stand Pipe

PENTAIR

Design Detail: Flow to Drum-Screen & MBBR

• MBBR nitrifying capacity for ammonia from 40 kg feed / day

PENTAIR

Design Detail: Water Treatment & Return System

Constant Flow Pumps, UV Filters, Heat Pumps, Oxygen Contactors Blending RAS and AquaPonics:: Engineering Flexibility Into Fish & Plant ProductionPlant

PENTAIR

Plant receive an optimum level of light yielding optimum growth rates

• Each Tray is lit with twenty 250-watt T5

Grow Lights, 5500K (cool lamps for leafy growth) suspended about 0.5 m above the plants; A total of 300 bulbs per floor.

• Pictured above are the drain lines leading from the

Trays to the Drum Screen Filter or first stage of the Moving Bed Bio Reactor (MBBR)

Farm Operation

PENTAIR

Farm Operation:

• The Stained Water

is also due the addition of Chelated Iron

Water Reuse Systems without Ozone Result in Clear but Stained Water

PENTAIR

Farm Operation: Starting Up the Plant Production

• Fish

production from the facility is expected to be 23 – 28 mt per year

The Link Between the Fish and Plants occurs at the Biofilter

PENTAIR

• Easier water

quality monitoring and controls

• Higher productivity/m2

• Labor cost for multiple crop Operational Culture Density met the Design Criteria

Farm Operation: Close Proximity of Fish and Plants

PENTAIR

Plant Production: From Seedling to Marketable Product

Some of the product

can be harvest as

early as 25 days

(Baby Greens)

PENTAIR

Expected Production from this Facility

Waste water will be collected in the basement of the building, solids

removed and some water reused Blending RAS and AquaPonics:: Engineering Flexibility Into Fish & Plant ProductionPlan

• Fish production from the facility is expected to be 23 – 28 mt per year

• Annual plant yield of 450 mt of lettuce and fresh herbs

PENTAIR

Harvesting Plants at Three Levels

A Movable Lift Provides Access to the Plants at Three Levels

PENTAIR

Plant Production from this Facility

Produce are cut and to market in two to three hours

Primary Waste Treatment Technology

Belt Filters provide a proven method of thickening solid waste in aquaculture

From: www.salsnes-filter.com

PENTAIR

Primary Waste Treatment: Membrane Filter Technology

Membrane Bio-Reactors (MBR’s) show great promise in treating wastewater.

An MBR is a compact-built purification system combining the biological degradation step with a membrane separation step. From: http://www.x-flow.com

PENTAIR

With deep trough AquaPonics, bacteria play a large role in nutrient recycling.

• Freshwater or halophytic grown on Styrofoam boards floating in the trays.

• Waste nutrients are removed by root mass as the water flows through the trays.

AquaPonics Systems Consume Nutrients and Clarify Water
