Anaerobic protozoa and their growth in biomethanation systems

Priya, M; Ajit Haridas; Manilal, V B (Springer, 2008)

This study was to investigate growth of protozoa and its influence on biodegradation in anaerobic treatment systems. It was done by specifically controlling and monitoring growth of protozoa versus degradation in continuous ...
Banana pseudostem characterization and its fiber property evaluation on physical and bioextraction

Jayaprabha, J S; Brahmakumar, M; Manilal, V B (Taylor & Francis, 2011)

This paper presents composition of different layers of banana pseudostem sheath and detailed characteristics of fibers from physical and bioextraction. Cellulose, hemicellulose, lignin, pectin, and ash were determined by ...
The buoyant filter bioreactor: A high-rate anaerobic reactor for complex wastewater - process dynamics with dairy effluent

Ajit Haridas; Suresh, S; Chitra, K R; Manilal, V B (Elsevier, 2005)

A novel high-rate anaerobic reactor, called "Buoyant Filter Bioreactor" (BFBR), has been developed for treating lipid-rich complex wastewater. The BFBR is able to decouple the biomass and insoluble COD retention time from ...
Characterization of surface-treated coir fiber obtained from environmental friendly bioextraction

Manilal, V B; Ajayan, M S; Sreelekshmi, S V (Taylor & Francis, 2010)

This study presents an ecofriendly color improvement method for clean bioextracted coir fiber with biogas recovery. The fiber samples were subjected to treatment with hydrogen peroxide (H2O2)and were optimized at 0.08% ...
Dynamics of sustainable grazing fauna and effect on performance of gas biofilter

Krishnakumar, B; Anupama, V N; Manilal, V B; Ajit Haridas (Society for Biotechnology, Japan, 2008)

The inherent operational problems of biofilters such as a pressure drop increase and nutrient limitations were managed in a toluene-removing gas biofilter with a sustainable grazing fauna consisting of micrometazoa and ...
Novel Eco-Friendly Commingled Polypropylene/Banana Fiber Composite: Studies on Thermal and Mechanical Properties

Anil, A; Tomlal, J E; George, G; Mathew, J T; Manilal, V B (Springer, 2016-10)

The thermal and mechanical properties of locally available bio-extracted banana fiber reinforced polypropylene commingled composite systems were studied. An entirely new method was adopted for the extraction of banana ...
Role of metopus es in the anaerobic degradation of organic matter and biomethanation process

Nimi Narayanan; Manilal, V B (Process Engineering and Environmental Technology Division, National Institute For Interdisciplinary Science and Technology (CSIR),Thiruvananthapuram, 2011)
Treatment of sulphide containing wastewater with sulphur recovery in a novel reverse fluidized loop reactor (RFLR)

Krishnakumar, B; Majumdar, S; Manilal, V B; Ajit Haridas (Elsevier Science, 2005)

A novel aerobic bioreactor, the reverse fluidized loop reactor (RFLR) was tested for recovering sulphur from aqueous sulphide in this study. The RFLR contained buoyant carrier particles on which chemolithotrophic sulphide ...
