At fish breeding humic acids are known for long as an integral part of natural waters for the bio-logical improvement of the water quality. For this purpose peat based products were often used to optimize the pH with the containing humic acids. Huminc acids based products on base of lignite like HuminFeed® in the field of aquacultures are an object for research for many years yet. Within the research acitivities regarding the use of HuminFeed in aquacultures and ornamental fish breeding the following positive effects amongst others could be observed by the Leibniz-Institute of Freshwater Ecology and Inland Fisheries in Berlin:

Intensive commercial shrimp farming began in the late 1960s led in part by technological advances and growing market demand. Today, shrimp farming is so intensive (in some cases close to 300 000 shrimps per hectare) that it requires industrially prepared shrimp feeds, fertilizing the ponds to stimulate the growth of organisms, aeration to prevent oxygen depletion and regular tidal water exchange. Solmax geomembranes have been used in some of the largest shrimp pond projects in the world. There are several key benefits of lining shrimp ponds with geomembranes. Durable and robust, the HDPE surface prevents weeds, grasses, mud and other obstructive contaminants from entering the pond. The HDPE substrate is known to reduce the suitability of the environment for bacteria thereby reducing the need for antibiotics. Geomembranes can also protect the slopes and banks from erosion and allow for easy detection and rapid removal of sediment and waste products.
Here are several factors to consider when deciding which type of geomembrane to use in a Shrimp Pond application:
- Stress crack resistance
- Tensile and elongation properties
- Tear and puncture resistance
- Duration of the project
- U.V exposure

TenCate Geotube technology is used for agriculture applications to reduce the waste in lagoons and utilize the contained nutrients for crops. This dewatering technology reduces the lagoon size by 50%, reduces labor and energy for land application by 50-70%, stores contained nutrients until needed for crops, provides higher quality flush water and reduces the odor and insect problems normally encountered. Over time, these solids dry in the dewatering containers, making the contained nutrients easier to transport and apply to crops.

In the dairy industry, the composition of the effluent stream varies according to the type of product. The water may, for instance, contain emulsions or have an extreme pH value or high temperature. Therefore, the treatment method required depends on the produced dairy product. AQUA Industrial Watertreatment offers various systems to treat the wastewater efficiently. With the help of a large Dutch dairy producer, a specific treatment process LOCO® has been developed, which has been adapted for use in the general production process.

Surface preparation: Your pond surface needs to be clean, dry and structurally sound. We suggest not using any detergents in your Pond. A medium bristle brush and water is all that is needed. You want the surface to be clean of any dirt that will be picked up with the nap of the roller or in the paintbrush used during the application process. Avoid cleaners and detergents since any remaining residue may harm your fish or plants. Only if your pond does not have plants or fish should you consider using cleaning solutions. On an epdm liner that has not been coated with other coatings it is simply a one coat application of PondPro2000.

Sustainable energy from farm-based residue can be a valuable source of income for farmers. Many countries now actively promote biogas upgrading for use in the gas grid. We have found that a robust design and a simple operation works best for farms. 24/7 support further enhances the already very high level of reliability. Technological flexibility allows for a quick response to changing circumstances and the seizure of opportunities as they arise.
