Abstract
A culturing pool for algae comprises a circular pond for containing a controlled fermentation of marine or freshwater algae. Submerged air jets or nozzlesCmaybe arranged along a bed of the pond which pump controlled tangential bursts of air pressure into the water. The introduced air causes the water to rotate around the tank. FinsBmay be provided in the pond to cause vortices to form in the water so that the algae are mixed. The jets help to aerate the algae. Power for the process may be derived from photovoltaic panels with stored circulating capacity provided by a compressed air storage vessel.
Description
Ponduzzi
Background
In recent years, there has been a large increase in interest in cultivating algae for a variety of purposes. The present interest is largely driven by a desire to produce fuel from plant sources. There are around 90,000 known types of algae, with more being discovered all the time. Of these, a few such as Spirulina are already in commercial production and a number of others are known to contain high levels of nutritionally important substances such as vitamins, minerals, omega 3 and omega 6 fatty acids.
Under the right conditions, Algae are able to grow faster than any other plant, and as certain varieties can contain more than 50% oil, these varieties show potential for the production of bio-diesel.
Presently, most algae farming is carried out for mixed production of high value fine chemicals, so that as many different value streams are extracted as possible. In this way, algal bio-diesel is now approaching commercial production.
The Ponduzzi system The Ponduzzi is an open cultivation system for either micro-algae (single celled) or macro-algae (seaweed or fresh water weed). The Ponduzzi consists of a circular pond in which algae are circulated, and made to rise and fall within the water column by directed air jets. The aeration system provides moderate pressure air introduced tangentially and pulsed using an electronically or mechanically controlled valve to move water around the pond, and with it the cultivated biomass. The system serves the additional function of aerating the crop, and may be supplemented with added Carbon Dioxide, or with flue gases containing Nitrous Oxide. Both Carbon Dioxide and Nitrous Oxide are greenhouse gases, with the latter very much more powerful than the former. Algae metabolise and hence remove Carbon Dioxide from air / flue gases, so contributing to Carbon Sequestration. This process occurs during daylight as a result of photosynthesis. In regards to Nitrous Oxide and related oxides of nitrogen, the situation is rather different, and does not depend on photosynthesis. Algae therefore break down Nitrous Oxides continuously both day and night. By passing flue gases containing Nitrous Oxide through an algal tank, emissions are greatly reduced. The Ponduzzi can therefore provide supplementary treatment, or where flue gases are presently untreated, a crude primary treatment for Nitrous Oxide containing flue gases. Algae may also be utilised in a water treatment system based on the Ponduzzi design to remove a range of pollutants such as Nitrates, Phosphates, and heavy metals. The size and depth of the device are suitable to the crop selected and the desired output thereof. The device incorporates measures to regulate temperature by means of a cooling circuit, and will in any case, allow for accelerated cooling by evaporation due to the air flow through the aeration / propulsion system. Where the tanks are close to shore, further cooling is supplied by passing seawater through a cooling pipe which passes several times around the tank. For tanks further onshore, solar powered evaporative coolers can cool the tank via a heat exchanger. The same pipe work could serve duty as the delivery mechanism of a solar thermal heating system for winter use in cooler regions.
In order to generate vortices and so replace the surface area with that at depth, small fin structures are attached to the pond bed placed in front of each nozzle. Once created, the vortices move off around the tank turning over the biomass to optimise and accelerate the process of photosynthesis.
Air to run the circulating / aeration system is supplied by a compressor and compressed air storage vessel powered by Photovoltaic or Wind Power so as to have a low carbon impact, and fresh seawater for top up and replacement of the tank is similarly pumped. The system may be used in two different modes, batch, or continuous. In the latter, algae are continuously harvested, and water is regularly exchanged a little at a time.
The system contains a variety of sensors to monitor dissolved carbon dioxide, dissolved oxygen, biomass opacity (a measure of biomass density), temperature, salinity and volume.
Once harvested, the algae are filtered from the water (or for macro-algae fished out either mechanically or manually), and exposed are solar evaporation beds to reduce their water content prior to processin.g. In damp climates, this could be carried out in a greenhouse fitted with heat exchange ventilation.
