  • Pasture Trial – Waroona (2014/2015) - Case Study

    At Waroona in the Peel region of Western Australia in 2014, 12 by 1m square wire cattle cages were placed at random to evaluate the effects of Hibrix pasture treatment combined with 50kg/ha of super phosphate versus the growers standard fertiliser usage of 100kg/ha of super phosphate. The Hibrix treated plots produced significantly higher amounts of dry matter without any reduction in pasture ...

  • Freeze Drying of food samples prior to Pressurized Solvent Extraction

    In this Short Note, we highlight the Freeze Drying (lyophilization) and subsequent fat extraction of food samples. The SpeedExtractor E-914 / E-916 can be used only for solid or semi-solid samples. Residual moisture needs to be removed by mixing the sample with a drying agent such as diatomaceous earth. This can be omitted by using Freeze Drying: the drying is initiated mainly by direct ...

  • Pretreatment of brewery effluent to cultivate Spirulina sp. for nutrients removal and biomass production

    Due to the low concentration of nitrate and high contents of organics, brewery effluent was not suitable for the cultivation of Spirulina sp. This work changed the nutrient profile of brewery effluent effectively by dilution, addition of nitrate, and anaerobic digestion. The result showed that the optimum dilution rate and NaNO3 addition for brewery effluent were 20% and 0.5 g/L, ...

  • Use of sea water and hydraulic conditions. Potential cause of Mortality by Metals and Hydrogen Sulfide in Recirculation Fisheries

    The traditional conception in Chile of the toxic effect of metals on cultured fish tends to weigh heavily on incoming freshwater in open flow fish farms as the major responsible for mortality in early stages of development in salmon species. This approach is mainly based on two conditions that refer to freshwater quality in Chile, and to the dilutive effect of recirculation fish stocks when a ...

  • Revitalizing a hog waste lagoon

    A North Carolina hog grower with a brood barn of 200 full grown sows contacted Reliant Water Technologies to see if we could assist him with one of his waste lagoons. All of his lagoons were identical, measuring only .05 acres in size, and designed to be 8 feet deep. When we arrived at the farm all of the lagoons looked like the one in Figure 1. The lagoon that he chose for us to work with was ...

  • 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 ...

  • Study on method and mechanism of deep well circulation for the growth control of Microcystis in aquaculture pond

    In order to control the growth of Microcystis in aquaculture ponds and reduce its adverse effect on water quality and aquaculture, a production-scale experiment of deep well circulation treatment was carried out in an aquaculture pond with water surface area of 63,000 m2 and water depth of 1.6–2.0 m. Compared with the control pond, the experiment pond had better water quality as ...
