Category : Technology & Engineering
Languages : en
Pages : 579
Book Description
Wetlands have been used for uncontrolled wastewater disposal for centuries. However, the change in attitude towards wetlands during the 1950s and 1960s caused the minimization of the use of natural wetlands for wastewater treatment (at least in developed countries). Constructed wetlands have been used for wastewater treatment for about forty years. Constructed wetland treatment systems are engineered systems that have been designed and constructed to utilize the natural processes for removal of pollutants. They are designed to take advantage of many of the same processes that occur in natural wetlands, but do so within a more controlled environment. The aim of this book is to summarize the knowledge on horizontal s- surface flow constructed wetlands (HF CWs) and objectively evaluate their treatment efficiency under various conditions. The information on this type of wastewater treatment technology is scattered in many publications but a comprehensive summary based on world-wide experience has been lacking. The book provides an extensive overview of this treatment technology around the world, including examples from more than 50 countries and examples of various types of wastewater treated in HF CWs.

Author: Treatment of Petroleum Refinery Wastewater with Constructed Wetlands

Book Description
Pollution of waterbodies and the environment by petroleum industry is of particular concern in Nigeria. This problem can be addressed by the application of constructed wetlands (CWs) which is a nature-based system that is simple to construct, have low operational and maintenance costs in terms of supply of energy and its periodic maintenance. The application of CWs in Nigeria for polishing of petroleum refinery wastewater is an unprecedented research. This PhD thesis focused on some specific objectives which were characterization of treated secondary refinery wastewater, design, construction, operation and monitoring of planted (T. latifolia, C. alternifolius and C. dactylon) and unplanted vertical subsurface flow, horizontal subsurface flow and hybrid CWs for the removal of suspended solids, nutrients, heavy metals, organic matter and organic pollutants. The CWs effectively treated the petroleum contaminated wastewater to effluent compliance limits. In this study, T. latifolia planted CWs had consistently higher removal efficiencies for all the measured parameters than C. alternifolius and C. dactylon planted CW systems. Therefore, in order to improve the wastewater quality discharged by Kaduna Refining and Petrochemical Company (KRPC) Nigeria, meet stringent guidelines and protect the recipient streams, installation of CWs at the effluent discharge point of KRPC is strongly recommended.

Aquatic Macrophytes: Ecology, Functions and Services
Author: Sanjeev KumarPublisher: Springer Nature
ISBN: 9819938228
Category : Science
Languages : en
Pages : 317
Book Description
This book is a comprehensive collection of information about the features, functions, and services of aquatic macrophytes. As primary producers, aquatic macrophytes form the basis of food webs, play a major role in highly productive aquatic ecosystems, and have a significant impact on ecosystem functions and services. Macrophytes are also known to strongly influence the micro-climate and biogeochemical processes occurring in the littoral zones of marine ecosystems and the sediment dynamics of freshwater systems. They also serve as highly effective carbon sinks and play an important role in carbon sequestration. This book deals with various aspects of aquatic macrophytes, including nutrient recycling, biogeochemical processes, biomass production, wetland ecosystems, water resource management, carbon sequestration, environmental clean-up, and bioenergy production. Additionally, it presents the current status of aquatic macrophytes and discusses the impact of climate change on these plants. The book also highlights the major challenges associated with harnessing the benefits provided by aquatic macrophytes as ecosystem services. The book holds value and relevance for academicians and scientists working in the related domain. Additionally, it will serve as a valuable resource for students and researchers working in the field of ecology, biogeochemistry, wetland conservation, phytoremediation, elements biomonitoring, wastewater management, bioenergy production, etc.
Optimizing Stormwater Treatment Practices

ISBN: 1461446244
Category : Technology & Engineering
Languages : en
Pages : 344
Book Description
Optimizing Stormwater Treatment Practices: A Handbook of Assessment and Maintenance provides the information necessary for developing and operating an effective maintenance program for stormwater treatment. The book offers instructions on how to measure the level of performance of stormwater treatment practices directly and bases proposed maintenance schedules on actual performance and historical maintenance efforts and costs. The inspection methods, which are proven in the field and have been implemented successfully, are necessary as regulatory agencies are demanding evaluations of the performance of stormwater treatment practices. The authors have developed a three-tiered approach that offers readers a standard protocol for how to determine the effectiveness of stormwater treatment practices currently in place.
