Technology

Agriculture is often wrongly categorized as a low-tech sector. At Green Oasis our farms run on state-of-the-art technology-driven data analytics. This information allows machine learning and artificial intelligence to optimize our crop production.  We have developed one of the largest integration systems ever built.

CEVAS

CEVAS, (Closed Environment
Vertical Aquaponics System) is the
technology we use to assist our
farmers in managing control,
measurement, automation, diagnostic
and analytical aspects of the farm.

 

This includes continuous monitoring of air temperatures, humidity, H2O temperatures and pH levels, nutrient and mineral profiles, flow rates and levels of dissolved oxygen. Any variances outside acceptable limits are instantly transmitted over a triple redundancy communications network to operations personnel on a 24/7 basis.

Layered Raft Beds

Every year, each raft bed can produce roughly 17 crop cycles. Each raft bed is measured at 8’ by 120’, and holds 152 rafts. The 4” of water that the rafts are floating on is exchanged every 2 hours to ensure a constant supply of nutrients, thermal energy, and aeration. 

Bio Security
Terra Universal Air Shower

To ensure pest are not accidentally brought into the facility, employees and visitors will be required to pass through air showers and then don washable coveralls. An example of these showers are those designed by Terra Universal. This is to protect each of the individual production bays, ensuring that product loss due to pest infestations and mold are kept to a minimum. 

The facility is subdivided into four bio secure zones.  Each zone is comprised of a fish farm working symbiotically with five aquaponic raft towers for plant production.

Automated Raft Retrieval

Through a contract with Confirmed Automation Systems, GOF has designed a fully automated plant harvesting system specializing in handling all the rafts in our aquaponic system facility, from raft retrieval, harvesting, washing, seeding, to loading again. 

Solids Filtration

"Rotary microscreen drum filters are ideal for the removal of fine suspended solids in recirculating systems where water reuse strategies are imperative—zoos, aquariums, greenhouses, aquaculture systems, wastewater treatment plants, and more. PR Aqua Rotofilters are trusted by facilities worldwide for critical filtration needs. Constructed of the highest-quality materials and engineered for the rigors of commercial aquaculture, PR Aqua Rotofilters provide exceptional reliability and a long service life. Designed with the needs of the commercial operator in mind, the filters are also inexpensive to operate. Rotofilters are also available in two configurations; fully-enclosed or frame-mounted. With flow rate capacities from 50 to 7,000 gpm (11 to 1590 M3/HR) and micron ratings from 11–80 (custom sizes available upon request) there is sure to be a Rotofilter that meets the requirements of your application."

Biodigestion

Nutrient conversion is a process in which beneficial aerobic bacteria do the work of breaking down solid waste from the fish into nutrients that the plants need to thrive. In GOF facilities, this process takes place in a patented process called O.O.R.B.S, created by Living Planet Solutions. The efficiency of the conversion of nutrients from the fish for the plants is particularly important to the financial success of CEVAS. There is a direct correlation between nutrient conversion and plant crop production. 

"The O.O.R.B.System was designed to ensure the right environment for the growth and proliferation of the specific bacteria and microorganisms that are necessary for the release of nutrients in the correct form for absorption by plants and the control of pathogens." - Living Planet Solutions

 Seeding & Harvesting

To keep up with continual harvests, every week each production bay will require 1368 rafts with freshly sprouted plants. To do this efficiently and effectively, seeding machines take clean rafts and with precision, delivers seeds evenly on each raft. Afterwards, freshly seeded rafts are sent to the crop production bay towers to begin the plant’s life cycle.

One harvesting machine, one washing machine, and one seeding machine can handle the required tasks at a rate of 300 rafts an hour. Labour is needed to oversee these processes and to ensure efficient use of the machines, with each machine needing a single person to oversee the operations. Afterwards, the plant product is sent to the packaging equipment to prepare it for market.
