  • 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 ...

  • A novel growth method for diatom algae in aquaculture waste water for natural food development and nutrient removal

    Diatom algae are known to play an important role as primary producers in many diverse ecosystems, including artificial aquaculture ponds where they also aid in maintaining water quality by consuming excess nutrients. But factors influencing their growth are still poorly understood. In the present study the effect of micronutrients, N:P ratio and silica concentration on benthic diatom Synedra ...

  • 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, ...

  • Ecological impacts of fluridone and copper sulphate in catfish aquaculture ponds

    Fluridone and copper sulphate are often used for controlling macrophytes and algae in aquaculture ponds. The present study examined the ecological effects of these chemicals on macrophyte, phytoplankton, and zooplankton biomass, plankton community structure, water quality parameters, and fish survival and yield in catfish culture ponds using a randomized complete block design. The estimated ...

  • Using full-scale duckweed ponds as the finish stage for swine waste treatment with a focus on organic matter degradation

    The rapid increase in the number of swine has caused pronounced environmental impacts worldwide, especially on water resources. As an aggregate, smallholdings have an important role in South American pork production, contributing to the net diffusion of pollution. Thus, duckweed ponds have been successfully used for swine waste polishing, mainly for nutrient removal. Few studies have been ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...
