  • Adsorption of model textile dyes from aqueous solutions using agricultural wastes as adsorbents: equilibrium, kinetics and fixed bed column study

    Gram husk and groundnut shell are cheap and abundantly available agricultural waste materials in India. A systematic study on the adsorption of some model dyes from aqueous solution on these low-cost adsorbents has been attempted. Model dyes used were Methylene Blue, Rhodamine B, Congo Red, Eosine Y and Metanil Yellow. Equilibrium, kinetics and column experiments were performed. Effects of ...

  • A new reactor for denitrification and micro-particle removal in recirculated aquaculture systems

    A ‘membrane-denitrification’ reactor (MDR) was developed and tested in a semi-technical recirculation aquaculture system in comparison to a double – without MDR – as reference system. The MDR consisted of a reactor with an ultrafiltration membrane unit for removal of micro-particles (e.g. sludge flocs, bacteria and parasites). Specific carrier material provided surfaces for biofilm growth in a ...

  • Forced ammonia stripping from livestock wastewater: the influence of some physico-chemical parameters of the wastewater

    In highly alkaline aqueous solutions (pH >10), the main form of dissolved ammoniacal nitrogen is the unionized free ammonia. Free ammonia, being a gaseous molecule, is easily stripped out from the solution. Increasing wastewater pH is frequently used to force ammonia removal. Herein, the effect of the variation of some physico-chemical characteristics of liquid cattle wastewater on ammonia ...

  • Using a Walnut Shell Filter as an RO Protection Filter

    The purity of boiler feed water can be a critical part of the manufacturing process. This water needs to be free from contaminants in order for the boiler to operate correctly, without frequent shutdown for maintenance. For this reason, a membrane filtration train is frequently used. Unfortunately, the exposure of plant water to the manufacturing process means that the feed water can be ...

  • Worming the way to finished compost

    SCREENING AND GRINDING When materials from CR&R and other generators are unloaded, a preliminary screening separates out nonorganic contaminants.    Even though there are source separated programs in places like Temecula and Lake Elsinore, there is the occasional appearance of plastic and glass that needs to be sorted out. Next, Bodlak’s crews put materials through a Vermeer tub ...

  • Comparison of the biological NH3 removal characteristics of a three stage biofilter with a one stage biofilter

    A three stage and a one-stage bench-scale biofilter with effective heights of 129 cm filled with same type of packing material were operated at different influent concentrations of ammonia in order to investigate their performance in treating waste gas streams. The columns contained a mixture of municipal compost inoculated with thickened municipal activated sludge as a base material and shredded ...

  • A cost-effective method for controlling compost air emissions

    In October 2007, ECS began conducting trials at California State University Fresno (CSUF) to explore using the new patent pending AC Composter (ACC) covered aerated static pile system to manage dairy manure solids and comply with airquality standards. A two-zone portable pilot system was delivered by ECS and installed at the CSUF research dairy. This research is being conducted under a Phase I ...

  • Simultaneous removal of rotavirus and adenovirus from artificial ground water using hydrochar derived from swine feces

    Hydrothermal carbonization technology can convert fecal waste into a valuable carbonaceous product referred to as hydrochar. We investigated the potential of fecal waste-derived hydrochar as an adsorbent for virus removal in water treatment. Swine feces was hydrothermally treated under two conditions: at 180 °C for 2 h and 230 °C for 7 h. The resulting solid products (hydrochar) were evaluated ...

  • Seasonality & optimal calf care

    Changing seasons, and challenging seasonal extremes (cold, heat and humidity), add extra challenges for a young calf and the caregivers management must be dynamic in order to provide optimal care. A reminder of calf needs should be outlined, especially with the primary calf worker(s). Topics of focus should involve: Optimal nutrition, the importance of access to clean water, clean and dry resting ...

  • Cocomposting at Pearl Harbor

    Cocomposting at Pearl Harbor When the Hawaii Department of Health tightened its restrictions on landfilling biosolids by requiring the lining of sludge drying beds, the U.S. Navy Public Works Center (PWC) at Pearl Harbor decided to look for a less expensive alternative to landfilling. Biosolids composting became the Navy’s answer. A pilot project was started in July, 1997, and the full-scale ...

  • Manure Compost A New Cash Crop

    A growing number of livestock producers are discovering manure compost as a new cash crop. When Mark Meyer refers to the “magic” at New Day Farms, he isn’t referring  to  the  liquid  egg  products  generated  by more than 2.5 million laying hens. Rather, Meyer, the environmental manager  at the Ohio facility, is talking about the ...

  • Potential pollutants from farm, food and yard waste composts at differing ages: Part I. physical and chemical properties

    There is little information about the changes in physical and chemical properties of compost as a function of compost feedstocks and age of the compost mixture. As a consequence of this gap, the potential of compost to serve as a pollutant source relative to compost age (from initial mixing of raw feedstocks to mature compost) and feedstocks (i.e. % of food, manure, bedding, leaves, etc.) during ...
