Abstract

Excessive concentrations of metals in industrial effluents may adversely affect the performance of sewage purification works. Although there is existing technology for treating these effluents, it has not found wide application due to costly equipment and chemicals and the absence of sufficient space on most plants. In this paper the feasibility of removing these metals from dilute solutions by electrolytic precipitation using a particulate electrode is investiga ....etc

ABSTRACT
Miniaturization is the order of the day. Until recently a decade ago traditionally watch parts were considered to be the micro components one can think off. Recent changes in societyâ„¢s demand have forced us to manufacture variety of micro components used in different fields starting from entertainment electronics to be bio medical implants. Present day manufacturing processes used for miniaturization are the micro electronic fabrication techniques used for Micro Electro Mechanical Systems ....etc

The advent of nanotechnology in cancer research couldnâ„¢t have come at a more opportune time. The vast knowledge of cancer genomics and proteomics emerging as a result of the Human Genome Project is providing critically important details of how cancer develops, which in turn creates new opportunities to attack the molecular underpinnings of cancer. However, scientists lack the technological innovations to turn promising molecular discoveries into benefits for cancer patients. It is here that nanotechnology can play a pivot ....etc

The advent of membranes makes the wastewater treatment easier nowadays. Activated sludge process (ASP) , which is the oldest technique in wastewater treatment , is combined with highly efficient membrane filtration to start a sophisticated technique called Membrane Bioreactor (MBR).It is an efficient process for maintaining a long solids retention time(SRT) at a relatively short hydraulic retention time(HRT),which is needed for the treatment of waste water. MBR is favored to all other conventional techniques because the treated water is free fr ....etc

With the increase in population, natural resources of water are being polluted. Ozone technology reveals one of the most efficient and effective method of achieving pollution removal in water. Ozone is the most powerful broad spectrum microbiological control or disinfecting agent available for water treatment. It is highly reactive and unstable. Considering chlorine which is the most commonly used water disinfectant chemical, O3 is 15% stronger oxidizer and kills bacteria 3000 times faster. The important advantage of O3 is that it produces no t ....etc

PLASMA TECHNOLOGY
FOR
WASTE TREATMENT
ABSTRACT
In Nature there is no such thing as waste. If it were not for the waste oxygen that plants produce, we would not have oxygen to breathe Part of the plan for re-using material from living things is to have it decompose(treat) so that it can be assimilated by another life form. These ideas opened the doors for the evolution of a technique called Plasma technology.
Plasma technology is not a new technology but its application for waste treatment, electricity generatio ....etc
