Waste water is gold under our feet
Each winter, we can see the heat, warm air, coming up the sewer shafts in city streets and we should realize the enormous heat potential that is down there and just flows away, untapped and [...]
Sustainable Desalination of Fresh Water
Seawater reverse osmosis is an advanced desalination process used to filter water in which seawater is forced through a semi-permeable membrane, producing pure water on one side and concentrated brine on the other. The process, [...]
AltelaRain Produced Water Treatment & Re-use
Altela Inc. offers a fundamentally new water desalination product, the AltelaRainSM System (ARS) that inexpensively removes nearly 100% of dissolved salts and other contaminants from industrial wastewaters and undrinkable brackish waters. Altela has taken the [...]
Using Secuirty Monitoring Tool to Improve Operation of the Water Distribution System
The distribution system represents the last analytical frontier in the water quality industry. Since 9/11, numerous communities have installed multi-parameter monitoring stations in locations throughout the distribution system as early warning systems based on potential [...]
Innovations in Energy Efficient Decentralized Wastewater Treatment Systems:
This paper will provide a brief overview of differences between conventional centralized wastewater treatment systems and the more recent decentralized systems. Brief comparisons will be made regarding differences in scalability, economics, energy efficiency, and environmental [...]
Enviroquip Membrane Bioreactor Systems – Novel Wastewater Treatment Process for Enhanced Nutrient Removal
Traditional wastewater treatment technologies are not sufficient in protecting sensitive receiving waters. Agencies are required to meet Enhanced Nutrient Removal (ENR) limits that are increasingly difficult to achieve (e.g. 3.0mgN/l and 0.1mgP/l). Various techniques are [...]
Removal of Heavy Metals From Aqueous Solutions with Calcium Alginate Beads
The present research is focused on the development of a bio-sorbent based on alginate beads. The alginate is a natural polymer extracted from brown seaweed with capability of hosting divalent cations in gel state, which [...]
Mobile thermal unit for PCB destruction
FRALMA™ Technologies has designed and built a mobile device especially to destroy hazardous material, more specifically PCB-contaminated oils. The major benefit offered by FRALMA ™’s device is its mobility. It can easily move around in [...]
A Sonoelectrochemical Synthesis of Nanosized CdS on TiO2 Nanotube-Array for Enhancing Photoelectrochemical Reactivity
The nanoparticles of CdS were precipitated onto a self-organized TiO2 nanotube array photo-electrodes by using sonochemical synthesis combining with constant current electrochemical deposition. It is indicated that the CdS nanoparticles with average diameter of 28.1 [...]
Effect of surfactant on TiO2/UV mediated heterogeneous photocatalytic degradation of DDT in contaminated water
The toxic effects from the use of pesticides are of great concern to the environment. The pesticides containers are not treated according to the Mexican normativity and hence increase the pollutant levels in the environment, [...]
12 Billion Dollars Annually Expended on Throw away Filters- There is a new technology alternative to this wasteful practice
In a world that is focussed at finding methods to use less energy or alternatives to existing energy driven products, one obvious change that is essential is the reduced use of disposable products. Specifically this [...]
The Need and the Quest for Developing Water Treatment Systems for Masses Which are Low Cost, Low Tech and Use Locally or Easily Available Material
In todays world, a large set of environmental challenges exist. The extent of the environmental damage is alarming and the consequences could be dire. Existence of healthy life requires availability of safe food and clean [...]
Isolation and Characterization of Benzene Degrading Bacteria from Gasoline Contaminated Water
The BTEX (benzene, toluene, ethylbenzene, and xylene)compounds are hydrocarbon pollutants that are considered as significant threat to the health and environment. Among BTEX, benzene is of major concern, because it is soluble, mobile, toxic, carcinogenic [...]
Method for Converting Waste Plastic to Hydrocarbon Fuel Materials
The increased demand and high price for energy sources are driving efforts to convert organic compounds into useful hydrocarbon fuels. Although much of this work has focused on biomass, there are strong benefits to deriving [...]
Achieving a Sustainable Metals Market for the Manufacturing Industry
Metals are a key resource in today’s manufacturing processes. However, the environmental costs of procuring and processing new metals can potentially set companies back in their endeavors to be more environmentally friendly, while also increasing [...]
