Pollutant treatability: a molecular engineering approach

Direct catalytic hydrodechlorination of toxic organics in wastewater

“…A number of industrial processes produce wastewater-containing chlorinated hydrocarbons (CHCs) (Surprenant et al, 1985), and a wide variety of methods, such as air stripping, carbon adsorption, and biological treatments, have been used to reduce their quantity in such discharge streams (Strier, 1980;Patterson, 1985). When the treatment method is a separation technique, such as air stripping or adsorption, the recovered CHC often requires further treatment.…”

Electrochemical Processes for In-situ Treatment of Contaminated Soils

“…Extensive research has been conducted to use isolates from the soil-water system (Stief, 1984;Mckinnon and Dykessen, 1984;Strier, 1980;Macay and Shiu, 1981;Wood, 1980;Martinez, 1986;Chivers, 1971). However, the sustainability of these enriched isolates in the natural environment remains unknown.…”

Biodegradation of phenol by aerobic granulation technology

“…Physical, chemical and biological methods are used for removal of aromatics from the groundwater (Strier 1980;Atlas 1981;Kobayashi & Rittman 1982;National Academy of Sciences 1983;Gils & Pirbazari 1986). Among these methods biological method is preferred if complete oxidation to carbon dioxide and water can be achieved.…”

“…Among these methods biological method is preferred if complete oxidation to carbon dioxide and water can be achieved. Physical and chemical methods have drawback because in these methods intermediates are formed, that are even more toxic than the original compounds (Strier 1980;Gils & Pirbazari 1986). Like in the case of phenol, bulk removal of phenol by solvent extraction, absorption, chemical oxidation, incineration and other non biological treatment methods are used and these suffer from serious drawback such as high cost and formation of hazardous by products (Loh et al 2000).…”
