Industrial wastewater containing toxic waste compound and metal ions pose manyproblems of disposal. The most generally used method of removing metalcontaminants is lime treatment to precipitate metals as hydroxides. The metalis not normally recovered resulting in the need for sludge disposal. The costof sludge disposal plus fewer available disposal sites makes that methodincreasing less attract ...

No one questions the philosophy that it is better to avoid industrial pollutionrather than to attempt the clean up of an environmentally abused site.Unfortunately, we are slow to learn this lesson and hazardous wastes become moreexotic and continue to increase. Causing 21 of the 28 EPA superfund sites in theSilicon Valley (Witkowski and Menon 1991), the semiconductor industry was, andcontinues to ...

The proposed sorbents will have potential applications in i) industrial wastewater treatment plants, ii) municipal wastewater treatment plants, iii) nuclear waste treatment plants, iv) drinking water treatment plants, v) several types of existing point-of-use and point-of-entry water purifying systems, and vi) for remediation of various mercury contaminated sites using permeable reactive barrier ( ...

The sorbent proposed to be developed by Lynntech, Inc., in this Phase I project will have potential applications in: (1) industrial wastewater treatment plants, (2) municipal wastewater treatment plants, (3) nuclear waste treatment plants, (4) drinking water treatment plants, (5) several types of existing point-of-use and point-of-entry water purifying systems, and (6) for remediation ...

Fumed silica is an important additive in many products, including paints, plastics and tires, and is a $1.5 billion market with a 6 percent growth rate. However, fumed silica producers rely on an energy- intensive, costly and hazardous process. The air pollution resulting from the energy utilized to produce fumed silica is a combination of carbon emissions from the production of raw materials, ene ...

Harmful algal blooms (HABs) occur in aquatic environments when conditions trigger an increase in the abundance of organisms that produce toxins. The toxins are transferred through the food web where they affect and even kill zooplankton, shellfish, fish, birds, marine mammals, and possibly humans. HABs have been estimated to cost the U.S. economy as much as $50 million per year due to the closure ...
