  • Algae biomass cultivation in nitrogen rich biogas digestate

    Because microalgae are known for quick biomass growth and nutrient uptake, there has been much interest in their use in research on wastewater treatment methods. While many studies have concentrated on the algal treatment of wastewaters with low to medium ammonium concentrations, there are several liquid waste streams with high ammonium concentrations that microalgae could potentially treat. ...

  • Recovery of photosynthesis and growth rate in green, blue–green, and diatom algae after exposure to atrazine

    We evaluated the recovery of photosynthesis and growth rate in green (Pseudokirchneriella subcapitata), blue‐green (Anabaena flos‐aquae), and diatom (Navicula pelliculosa) algae after pulsed exposure to atrazine. Subsequent to a grow‐up period of 24 to 72 h to establish requisite cell density for adequate signal strength to measure photosystem II (PSII) quantum yield, algae were exposed to a ...

  • The treatment of (fish) ponds on an environmentally friendly manner with the usage of the LG Sonic case study

    Aquaculture, or aqua farming, is the cultivation of aquatic organisms, such as fish or shrimps, in a controlled environment. Where this happens in a closed water container, algae may occur that pollute the water and may damage the organisms grown. Many of the traditional methods to fight algae are either insufficient, cumbersome, environmentally unfriendly, or all of these. LG Sonic uses ...

  • Ecological swimming pond case study

    In spring 2009 LG Sound installed an LG Sonic in an ecological swimming pond in France. This pond has been suffering from the growth of filamentous algae for a long period of time. Even when the algae where removed, they grew back within a couple of days. Swimming or any other recreational use was made impossible in this pond. The LG Sonic products can shift the balance in a watery ecosystem to a ...

  • Cultivating energy crop production

    A NEW Farm Bill is moving through the Congressional legislative process. Along the way, commercial agriculture is debating the energy impacts of future corn and soybean production. The growth of corn-based ethanol and soybean-based biodiesel has created competition for the feed inputs into animal agriculture, namely corn and soybeans. While most of agriculture discusses energy production from ...

  • Prevent harmful conditions from damaging crops with sensor alerts

    Your algae monitoring and control system is all set up, humming along efficiently, and the algae is growing well. Your solenoids are controlling the CO2 input so that your pH is always on target. Coolers (or heaters) are controlling your temperature. Maybe you even have automatic harvesting based on the density of your algae. But what happens if one of the devices breaks down? Pumps, valves, ...

  • Conical Bottom Tanks-Backstory - Case Study

    Originally we only offered the flat bottom tanks in our line of tanks. Eventually, fit was discovered that they are ideal for growing algae with natural sunlight, however some growers wanted to something a little more. Several customers wanted an easier way to harvest the algae from the growth chambers, particularly the bottom. Siphoning works for the flat bottom tanks, and is a great option for ...

  • Open sea-based Aquaculture case study

    Salmon farming is a multi-billion dollar global industry facing considerable difficulties posed by growing pressure from environmental regulatory bodies. Because marine organisms grow on and “foul” synthetic nets, oxygen available to fish is reduced and infectious diseases and parasites can spread among the fish. A test to study the reduction of fouling formation on netting of fish ...

  • Field trial carried out in the ebro valley, Spain case study

    Rice farmers in Spain experience two major problems with their rice crops: After the flooding and fertilisation of the rice fields algal growth rapidly develops and covers the surface of the water in the paddy. This greatly reduces the availability of sunlight received by the seedlings until they have grown above the water level. This results in early stage plant loss which can be severe. The ...

  • Greenhouse packs a power punch

    Closed loop system utilizes gasification, algae ponds and anaerobic digestion to convert wood waste to a variety of products, including biofuel, biogas and a soil amendment. MICHAEL Smith is supervising the first commercial-scale Green Power House at the F.H. Stoltze Land and Lumber Co. near Columbia Falls, Montana. Smith, a physicist, has designed a system to take waste products and turn them ...

  • Pigs: Montfort Boys Town, Fiji

    Before 1996, Montfort Boy's Town, a school for disadvantaged boys in Suva, Fiji, taught students how to raise both food and funds by farming fish in ponds. In 1996, ZERI and Professor George Chan arrived, proposing a new integrated farming system that would expand their current efforts into FIVE healthy new enterprises by simply gathering the waste generated by a local brewery. These new revenue ...

  • Monitoring greenhouse gases from biofuel crops

    Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...

  • The advantages and disadvantages of culturing fish.

    The advantages and disadvantages of culturing fish. Experts develop practical recommendations for decision-makers, scientists and producers for a sustainable development of Mediterranean aquaculture. Human demand for fish is growing steadily. With fisheries decreasing worldwide, aquaculture is becoming an important socio-economic alternative and a source of proteins and healthy oils. ...

  • Seasteading could be the answer to sustainably feeding 9 billion people

    Self-sufficient nation states in the middle of the ocean might be our ticket to a sustainable future. Oceans cover 71 percent of Earth’s surface, yet provide less than 2 percent of the food we eat. The growing demand for seafood, however — predicted to rise to 8 percent during the next decade — from an already depleted and exhausted ocean is forcing ...

  • How did palm oil become such a problem — and what can we do about it?

    Production of this ubiquitous ingredient is devastating for the environment. Solutions are complex, but they are out there. Last August, from the window of a jet high over Sumatra, I counted nearly a dozen plumes of smoke rising from the vast jungles and plantations below. Some more than a half-mile wide, they looked like pillars holding up the sky. That week the ...

  • Crops flourish with Scalewatcher

    Water is an essential component of horticulture and agriculture whether it is used for irrigating field-scale vegetables, nursery stock, flowers or fruit.  Where water contains high degrees of calcium, magnesium and sodium, it can cause nutrient deficiency in plants and crops resulting in stunted growth and poor yields. Calcium also blocks irrigation systems and boilers in heated ...

  • Sustainable Soil Health

    “A Nation that destroys its soil destroys itself.” – Franklin D. Roosevelt. We have learned some harsh lessons about how to treat our soil. While most of us are aware of the problems of the past, some agricultural operations in the world are not heeding those lessons. We all know that healthy soil is essential to feed the ever-increasing ...
