Gallery: Wastewater Treatment Plant Upgrade Decreases Feminization of F...

 

Colorado’s Boulder Wastewater Treatment Plant recently received a multimillion-dollar upgrade, which was executed to address a number of problems — one of which was the high amount of chemicals seeping into the water table. After the upgrade, researchers found that the rate of feminization of male fish in Boulder Creek has decreased significantly. Feminization of fish and reptiles can result because of exposure to man-made chemicals that seep into the water table and act as endocrine disruptors. The chemicals can come from pesticides and fertilizers — as we’ve reported before — and from products people use every day, like soap, shampoo, cosmetics and pharmaceuticals.

    I work for a company called Bio Huma Netics, Inc. that produces and distributes various environmental products, including bioremediation, or wastewater treatment, solutions. Prior to joining this company, I knew very little about wastewater and its effects on the environment.

    When wastewater is left untreated, it usually does not meet all of the conditions for optimal microbial activity that leads to breakdown of waste solids. When microbial activity is not optimized, sludge accumulates and odors get out of control. However, if biosolids are reduced more efficiently and rapidly, runoff can be prevented. Also, odors will decrease and the sludge can be removed or recycled back into the environment. These bioremediation techniques are eco-friendly and get the job done efficiently – techniques that more wastewater treatment facilities should look into adopting.

    Ho…. I am very shocking about this news. http://www.apexmatch.com/marine.htm

    Sewage Treatment is now possible without the use of electricity.
    To make wastewater acceptable for reuse or for returning to the environment, the concentration of contaminants must be reduced to a non-harmful level, usually a standard prescribed by the Environment Agency and the non-electric Filter Sewage Treatment Plant gives a better quality of effluent than electrically operated plants.
    Surely, sustainability is the way forward?

    Waters that are used for drinking, manufacturing, farming, and other purposes by residences (toilets, baths, showers, kitchens, sinks), institutions, hospitals, commercial and industrial establishments are degraded in quality as a result of the introduction of contaminating constituents. Organic wastes, suspended solids, bacteria, nitrates, and phosphates are pollutants that commonly must be removed.

    To make wastewater acceptable for reuse or for returning to the environment, the concentration of contaminants must be reduced to a non-harmful level, usually a standard prescribed by the Environmental Protection Agency.

    Sewage can be treated close to where it is created (in septic tanks, bio-filters or aerobic treatment systems), or collected and transported via a network of pipes and pump stations to a municipal treatment plant.

    Sewage Treatment, or domestic wastewater treatment, is the process of removing contaminants from wastewater and household sewage, both runoff (effluents) and domestic. The task of designing and constructing facilities for treating wastewaters falls to environmental engineers. They employ a variety of engineered and natural systems to get the job done, using physical, chemical, biological, and sludge treatment methods. Its objective is to produce a waste stream (or treated effluent) and a solid waste or sludge suitable for discharge or reuse back into the environment. This material is often inadvertently contaminated with many toxic organic and inorganic compounds.
