Self - Circulating Biogas Generation for Swine Waste

open access: yesProcedia Environmental Sciences, 2016
Waste management plays key role in the development of a nation. There are many technologies to produce and extract energy. Several investigation has been made for generation of biogas from animal waste. A total of about 89,600 tons of Swine waste is produced per day in India.

Soil carbon and physical-mechanical properties after successive applications of swine and poultry organic waste

open access: yesPesquisa Agropecuária Tropical, 2018
In agricultural crops, the use of swine and poultry waste as organic fertilizers results in gains in the productivity and reduction of production costs, but it may also change the physical properties and mechanical behavior of the soil, either increasing

A Swine Waste Package Biotreatment Plant for the Tropics

open access: yesWater Science and Technology, 1993
Management of small pig waste/wastewater in the tropics is considered as a rather difficult problem, especially in the land limited and populated areas. In order to eliminate the problem or difficulty in technology transfer, two bio-treatment processes, namely, modified hybrid anaerobic treatment (MHAT) and combined bio-fixed film and aquatic plant ...

Enhanced Biohydrogen Production with Increasing Ammonia Nitrogen during Co-digestion of Swine Wastewater and Food Waste leachate [PDF]

open access: yes대한환경공학회지
This study investigated the effects of ammonia nitrogen (NH3–N) concentration and the COD/NH3–N ratio on biohydrogen production during the acidogenesis phase of co-digestion with swine wastewater and food waste leachate. Acidogenic sludge obtained from a

Process development for nitrogen removal of swine waste

open access: yesWater Science and Technology, 2000
This research aims to effectively remove nutrients in swine waste by a combined process of upflow anaerobic sludge blanket (UASB) and biofilm process. For effective removal of nutrients, both anaerobic and anoxic reactors were constructed consecutively within a single anaerobic/denitrification (SAD) reactor to which aerobic reactor for nitrification ...

MANURE VALUE AND LIVEWEIGHT SWINE DECISIONS [PDF]

open access: yes
Produced as a joint product, economic theory suggests that manure value could influence livestock management decisions such as herd size and optimal market weights. This study examines the concept of manure and its connection with optimal replacement age
