Books about Effluent from Amazon.com

Current industry, government and public emphasis on containment of hazardous materials makes it essential for each plant to reduce and control accidental releases to the atmosphere. Guidelines for Pressure Relief and Effluent Handling Systems meets the need for information on selecting and sizing pressure relief devices and effluent handling systems that will maintain process integrity and avoid discharge of potentially harmful materials to the atmosphere. With a CD-ROM enclosed containing programs for calculating flow through relief devices, effluent handling systems, and associated piping, the book offers an important collection of state-of-the-art technology for safely relieving process equipment of such conditions as overpressure, overtemperature and/or runaway reactions. It provides information for two-phase and compressible gas flow to select and size pressure relief devices, piping, and effluent handling equipment, such as gravity separators, cyclones, spargers, and quench pools. The book has an important collection of state-of-the-art technology for safely relieving process equipment of conditions such as overpressure, overtemperature and/or run-away reactions. It provides information for two-phase and compressible gas flow to select and size pressure relief devices, piping, and effluent handling equipment such as gravity separators cyclones, spargers and quench pools.

Special Details: Includes CD-ROM with equipment design programs for use with Windows 95, 98, and NT.

The rapid expansion and increasing sophistication of various industries in the past century has remarkably increased the amount and complexity of toxic waste effluents, which may be bioremediated by suitable plants & microbes, either natural occurring or tailor-made for the specific purpose. This technology is termed as bioremediation.

Bioremediation is an eco- friendly, cost-effective and natural technology targeted to remove heavy metals, radionuclides, xenobiotic compounds, organic waste, pesticides etc. from contaminated sites or industrial discharges through biological means. Since this technology is used in in-situ conditions, it does not physically disturb the site unlike conventional methods i.e. chemical or mechanical methods.

In this technology, higher plants or microbes are used alone or in combination for phytoextraction of heavy metals from metal contaminated sites. Through microbial interventions, either the metals are immobilized or mobilized through redox conversions at contaminated sites. If mobilized, metal accumulating plants are put in place to accumulate metals in their body. Thenafter, metal-loaded plants are harvested and incernated to reduce the volume of waste and then disposed off as hazardous materials or used for recovery of precious metals, if possible. In case of immobilization, metals are no longer available to be toxic to organisms.

Description:
A second order kinetic model was developed to predict the rate and extent of NH"4^+ removal as struvite from anaerobic digester effluents. Alternative to this, NH"4^+ can be recovered from struvite and the remaining Mg^2^+ and PO"4^3^- can be recycled back to the wastewater to fix more NH"4^+. The NH"4^+ solution was retained and the remaining Mg^2^+ and PO"4^3^- were returned back to be mixed with wastewater. In a five-step process, NH"4^+ recovery was initially 92% and progressively decreased to 77% in the fifth stage, due to loss of Mg^2^+ and PO"4^3^- at each step in the supernatant. Finally, economic analysis of recycling nutrients was performed and compared to the one step process. The cost of NH"4^+ recovery was calculated as $0.36/kgNH"4-N which is lower than $7.7/kgNH"4-N the cost of one step process without considering the market value of struvite obtained in one step process. .

Both regulators and the regulated community can benefit from the thoughtful recommendations presented by experts in whole effluent toxicity (WET) testing and receiving stream impact prediction. This book delivers state-of-the-art assessments that reflect appropriateness of endpoints used in routine WET methods, degree and causes of WET test method variability, biotic and abiotic factors that can influence measured field responses to effluents, and relationships among effluent toxicity, ambient toxicity, and receiving system impacts..

Description:
Estrogenic potencies of the effluents or water samples from wastewater treatment plants (WWTPs), industries and hospitals and some receiving rivers in Beijing city were estimated by using a human estrogen receptor recombinant yeast assay. Estrogenic activity of industrial wastewaters was found to range from 0.1 to 13.3ng EEQ/L and decreased to the range of 0.03-1.6ng EEQ/L after treatment. Estrogenic activity in WWTP influent ranged from 0.3 to 1.7ng EEQ/L and decreased to the range of 0.05-0.5ng EEQ/L after treatment. In the receiving river waters, the estrogenic effect range was 0.1-4.7ng EEQ/L. These data suggest that treated industrial effluents and WWTP effluents of concern are not the only source of estrogenic pollution in surface waters in Beijing city. EEQ levels in Beijing river water are likely attributable to untreated municipal and industrial wastewaters discharged directly into the river. .
