  • Extreme Wastewater Treatment Deconstructing Chemical Weapons
    to a drastic reduction in their combined stockpiles of nuclear warheads In 2010 President Barack Obama s Administration signed and ratified the New START treaty which further reduced the imposed limits As outlined in the new treaty both parties must meet the central limits on strategic arms by Feb 8 2018 exactly seven years from the date the treaty was officially executed The new limits set deployed warheads at 1 550 significantly less than the original START I treaty and further reduced nuclear delivery vehicles Dismantling Chemical Nerve Agents One Step At A Time The burning question now is How does a nation with such vast chemical weapon reserves safely and securely destroy and dispose of such dangerous arms The various secure locations of weapon stockpiles around the country must adopt and undergo a destruction plan of action that may employ a unique technology process or one similar to plans conducted at other sites General Atomics a specialized contractor for the government located in San Diego was tasked with deconstructing reserves located at the Blue Grass Army Depot outside of Richmond KY They were in search of a prefilter that would provide a nearly suspended solids free water solution before feeding into their posttreatment process After General Atomics developed a proprietary process named SCWO super critical water oxidation designed to perform the final destruction of the organic components they selected Oberlin as the solution to their prefilter need to provide a less than one micron suspended solids free solution before feeding their SCWO treatment reactor for the final treatment step One of the big challenges was the large swing in total suspended solids TSS concentrations The filter needed to be mechanically reliable with high online operating time automatic to minimize operator exposure flexible in case the feed conditions changed and media had to be modified Oberlin came to General Atomics attention through a recommendation from one of their consultants and through previous testing report recommendations done for a similar technology General Atomics and Oberlin began working together initially with a five year development process agreement which eventually led to the two entities forming a partnership to dispose of the weapon reserves at Blue Grass Army Depot where Oberlin s automatic pressure filter is still currently installed Underneath the levels of personnel and environmental safety protections the process of destruction is relatively simple and takes only a few steps Destruction The nerve agent is drained from the missile and neutralized in caustic The energetic fuel is also drained and neutralized in caustic This process is known as hydrolysis and the resulting chemical compounds are known as hydrolysates Another parallel step is that the aluminum missile body needs to be thinly sliced and dissolved in caustic The three hydrolysates are then held to ensure agent destruction before being transferred to the next treatment step Neutralization The next step is the neutralization of the hydrolysates This involves using a special mixture of HCl H2SO4 and H3PO4 acids The neutralization step is very exothermic

  • The Future Of Energy-Neutral Wastewater Treatment Is Here
    municipality s total energy bill Water and wastewater utilities are highly regulated entities whose primary goals are to meet regulatory requirements for protecting public health and the environment for reasonable and fair rates Energy efficiency has not historically been at the top of the list of priorities Nevertheless as populations grow and environmental regulations become more stringent demand for electricity at water and wastewater plants is expected to increase by approximately 20 percent according to the EPA Moreover as electricity rates increase energy conservation and efficiency are issues of increasing importance for the budgets of municipalities The Path Toward Energy Neutral Wastewater Treatment The lingering effects of the global economic recession have placed additional financial burden on wastewater utilities as they strive to meet increasingly strict discharge requirements with aging infrastructure in need of repair and replacement Energy conservation on site generation and renewable energy are becoming increasingly important to wastewater utilities as energy policy energy economics and actions to mitigate climate change converge with the need to meet higher standards of wastewater treatment Many utilities are beginning to reduce grid connected energy consumption at their facilities through a variety of energy conservation and on site energy production measures Emerging disruptive innovations in technology combined with operational best practices are bringing into focus the opportunity to achieve energy neutral wastewater treatment On site generation of energy is achieved by extracting the energy content of the organics in wastewater and converting it into a useable form For example advanced anaerobic digestion biosolids and biowaste processing systems use bacteria in the absence of oxygen to break down organic matter to create biogas the biogas can then be combusted or oxidized and used for heating or with a gas engine to produce electricity and heat It can also be compressed and used as fuel for vehicles or sold for use in a natural gas grid while additional nutrient rich effluent can be used as fertilizer Designed to recycle biosolids into methane and valuable byproducts the advanced anaerobic digestion systems are key to offering a cost effective lowmaintenance way to turn sludge into electricity generating renewable energy that can be used to power the very facility producing the waste The technology can also be used to treat biowaste such as food waste fats oils greases FOG etc By combining the digestion of these external sources of organic matter with the digestion of organics in biosolids from wastewater treatment the energy production potential of a wastewater treatment facility can be significantly increased Consider this A city of 500 000 people produces roughly 75 000 tons of household and commercial food waste and more than 14 000 tons of sewage sludge By treating that waste with advanced anaerobic digestion the value of the methane byproduct used in one of GE s Jenbacher gas engines would produce about 5MWe of electricity alone enough to power 10 000 homes The greatest demand for energy in wastewater treatment is for providing oxygen to a biological system which is typically
