  • Root vegetables harvest and farm development

    Root vegetables season The autumn start is the time when vegetable producers have a lot of work. A collection of vegetables begins. Tension and nerves are often associated with it. All because the priority for farmers is to collect crops for which they worked hard all year round. It is important to make a good choice and select the machines suitable to your needs and four farm ...

  • 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 ...

  • 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. ...

  • 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 ...

  • 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 ...

  • 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, ...

  • 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 ...

  • 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 ...

  • Coco peat (Coir pith, coir fiber peat) is an Environmentally Sustainable Product for the Horticultural & Agricultural sector

    Coconut fiber usage has become very common among professionals in various industries due to the versatility of the product. In the horticultural, agricultural, or erosion control sector, coir has a remarkable reputation for its superiority to other available natural materials in the market. Coir fiber is found between the husk & the outer shell of a coconut husk. The individual fiber cells ...

  • Algae control in irrigation case study

    Reduction of aerobic bacteria and algae in irrigation reservoir Analyzed parameters After finalizing the test the following was observed: strong reduction in algae and aerobic bacteria concentration. This lower amount in micro-organism concentration, in the water leads to lower biochemical oxygen demand (BOD). This subsequently leads to the improvement of the quality of the ...

  • 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 ...

  • Comparative Sensitivity of Freshwater Algae to Atrazine

    Widespread use of environmentally persistent herbicides has led to increasing concern over their impact on aquatic ecosystems and nontarget organisms. The triazine herbicide atrazine (6-chloro-N-ethyl-N-[1-methylethyl]-1,3,5-triazine-2,4-diamine) remains one of the most heavily used pesticides worldwide, and was the second most commonly used convencional pesticide in the U.S. agricultural market ...

  • 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. ...

  • Online monitoring of algae concentration with ALGcontrol - Case Study

    Online monitoring of algae concentration with ALGcontrol The presence of algae in surface waters is a potential threat to the quality and ecology of the water system. The control and monitoring of the algae concentrations are therefore of high importance. Due to green algae problems in the water reservoir of a drinking water treatment plant, the ALGcontrol was installed to continuously monitor ...

  • `Legal, Regulatory & Political Considerations In Commercializing Algal Products` Panel Presented At ABO, October 1, 2015

  • On-line monitoring of algae concentration with ALGco - Case Study

    The presence of algae in surface waters is a potential threat to the quality and ecology of the water system. The control and monitoring of the algae concentrations are therefore of high importance. The ALGcontrol offers on-line monitoring of different kind of algae through fluometric a (fluorescence) technique. Fluorescence is the property of some atoms and molecules to absorb light at a ...

  • DOE-Funded Algae Foundation Education Initiative Announced

  • Toxicity of fluoride to aquatic species and evaluation of toxicity modifying factors

    A study was performed to investigate the toxicity of fluoride to a variety of freshwater aquatic organisms and to establish whether water quality variables contribute substantively to modifying its toxicity. Water hardness, chloride and alkalinity were tested as possible toxicity modifying factors for fluoride using acute toxicity tests with Hyalella azteca and Oncorhynchus mykiss. Chloride ...

  • Cultivation of microalgae (Oscillatoria okeni and Chlorella vulgaris) using tilapia-pond effluent and a comparison of their biomass removal efficiency

    The uptake of dissolved nutrients by microalgae is the primary way to remove nitrogen in aquaculture systems. Many authors have studied the use of microalgae to treat wastewater from aquaculture. However, excessive microalgae accumulation may cause high levels of organic matter and suspended solids in the final effluent. Thus, an efficient way to remove excess algae is needed in wastewater ...
