Itron, of Liberty Lake, Wash., sells meters to utilities to monitor (and to prevent wasting) water, gas, electricity and heat.
Due to special nanostructures and larger specific surface area, ZnO nano-clips are a promising material as photocatalyst for degrading the harmful pollutants in waste water and gas, anode material of lithium battery or supercapacitor for electrochemical energy storage, and sensor for detecting dangerous gas.
Estimates put spill volumes in the Niger delta among the worst on the planet, but they do not include the crude oil from waste water and gas flares.
He et al. [16] China's iron and steel industry: Firm 2006 2008 19.2 19.8 Inputs: net fixed assets, employees, energy Desirable output: value added Undesirable output: waste water, waste gas, solid waste TFP total factor productivity, GDP gross domestic product, BOD biochemical oxygen demand, COD chemical oxygen demand, SS suspended solids, SOx sulphur oxide.
The major parts consisted of high-pressure plunger pump, hydrogen peroxide tank, waste water tank, gas release valve, check valve, thermometer, pressure gage, heat exchanger, heater and reactor, temperature recording controller, condenser, back pressure regulator and effluent tank.
A number of towns have had to warn locals to boil tap water before drinking after water treatment plants were compromised by bromides in waste water from gas-drilling projects.
Apparently, this means that economic residuals, whether they be waste water, harmful gases, garbage or whatever, must be treated by a disposal process, and thus that he handles an environmental problem at an abstract level.
Some newer injection wells, including one in Ohio that handled waste water from the gas production process known as hydrofracking, have had small earthquakes, but the researchers found no evidence that these quakes were remotely triggered.
A wide range of nanostructures including core-shells, hollow particles and other architectures were designed with the objective of creating new and original functionalities targeting a wide range of fields such as information storage, waste water treatment, catalysis, gas storage and biomedical applications.
However, these typical physical and chemical techniques require not only high-energy (steam or electricity) but also corrosion-resistant and high-pressure reactors, resulting in increased demand of special equipments and cost of pretreatment as well as pollution, such as organic waste water and exhaust gas emission [ 6, 7].
