Organic pollution not only depletes the oxygen content in the river resulting in killing of fish and marine life but also leads to heavy algal growth downstream. Reclamation of Treated Effluent Complete reclamation of sewage effluent is not generally adopted. Presents a microbiological perspective on the design and operation of wastewater treatment systems. Covers the fundamentals of microbiology, aspects of chemical engineering, operation and modification of wastewater treatment plants. Emphasis is on the activated-sludge process. Each chapter contains worked examples, review questions and a bibliography.
Manures and Sewage Sludges for Algal Growth. The ever increasing amount of wastes originating from human activities has introduced changes to the environment and in particular to the water quality. These wastes can be categorised into wastes from agricultural, domestic and industrial activities. Design considerations for algal ponds and efficient use of photobioreactors and HRAPs for wastewater treatment are some other highlights. This volume addresses the applications, potentials, and future opportunities for these various considerations in water pollution mitigation using algal technologies.
Two main culture systems are available for algal production. An open system generally combines waste treatment with algal production. This system employs the use of ponds, which range from the oxidation ponds to the high-rated algae ponds. An oxidation pond recycles nutrients through a bacteria-algae symbiotic process. General terms used to describe different degrees of treatment, in order of increasing treatment level, are preliminary, primary, secondary, and tertiary and/or advanced wastewater treatment. In some countries, disinfection to remove pathogens sometimes follows the last treatment step. A generalized wastewater treatment diagram is shown in Figure 5.

A total of almost genera and species of the most important algae is included in the next 11 chapters of this manual, being considered according to their occurrence and significance under the general titles of algae in streams, algae in ponds, lakes and reservoirs, attached al- gae, algae and eutrophication, clean water algae, algae and.
The most often used ponds in domestic wastewater treatment are the stabilization pond General features of algal growth in sewage oxidation ponds book facultative lagoon. The stabilization pond is designed to be aerobic throughout its depth and the facultative lagoon will be anaerobic at the bottom and aerobic at the top.
This article will examine the normal uses of each of these treatment ponds. Finally, high rate algal ponds (HRAP) are open, paddlewheel-mixed, raceway ponds designed for wastewater treatment and resource recovery in the form of microalgal biomass for use as protein-rich.
The first of these are sewage lagoons and are often referred to as oxidation or stabilization ponds. These are the oldest of the managed wastewater treatment systems. Usually no more than a hectare in area and just a few meters deep, oxidation ponds are natural “stewpots,” where wastewater is detained while organic matter is degraded.
A Cited by: 3. IntroductionThe most popular wastewater treatment is Oxidation ponds, which will produce an effluent meeting the recommended microbiological and chemical quality guidelines both at low cost and with minimum operational and maintenance cost.
A low level of treatment is especially suitable in developing countries, not only from the point of view of cost but also in terms of the difficulty of. Facultative ponds (1–2 m deep) are of two types: Primary facultative ponds that receive raw wastewater, and secondary facultative ponds that receive particle-free wastewater (usually from anaerobic ponds, septic tanks, primary facultative ponds, and shallow sewerage systems).
The process of oxidation of organic matter by aerobic bacteria is Cited by: The investigations pertaining to zoo- and phytoplankton succession during prestabilization and stabilization of domestic waste water in a facultative pond operating at meters depth with an average BOD loading of kg per hectare per day and a retention period of 10 days revealed the following: 1.

Aerobic bacteria breakdown products of sewage, from complex organic substrates into simple inorganic products, fulfill the primary-requirements of these photosynthetic algae and in return the bacteria. Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils.
Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil.
Several companies and government agencies are funding efforts to reduce capital. A granular or particulate composition of matter that includes algae and bacteria is described.
The algal-sludge granules are generated by incubating a wastewater system with algae under specific quiescent conditions with illumination.
Once the algal-sludge granules are present, it is no longer necessary to maintain quiescent conditions, and reaction with wastewater under stirred conditions is Cited by: 3.
5 Environmental Effects. As with production and use of any fuels, aspects of biofuel production and use have benefits and adverse chapter discusses potential environmental effects from the production and use of algal biofuels, the potential influence of perceived or actual impacts on societal acceptance, and some of the health impacts potentially emanating from the specific.

This book aims to provide the reader with an overview of the science and application of a number of advanced oxidation processes, as well as to share the authors' views on the future research needs. By comparison to the engineered AOPs, one chapter of this book describes similar processes naturally occurring in the aquatic : Raceway ponds are typically constructed using concrete shell lined with polyvinyl chloride.
Dimensions range from 10 to m in length and 1 to 10 m in width with a depth microalgal growth of 10 to 50 cm . Ponds are kept shallow as optical absorption and self-shading by the algal cells limits light penetration through the algal broth .
