Installation and commissioning of high yield organic fertilizer granulating machine
The qualified granulation rate of high-yield organic fertilizer granulation machine is as high as 80-90%. It can adapt to a variety of different formulations. The compressive strength of organic fertilizer is higher than that of disc and rotary drum granulator, and the large ball rate is less than 15%. The particle size uniformity can be adjusted by the stepless speed regulation function of the ...

Biosorption of Pb(II) by Bacillus badius AK strain originating from rotary drum compost of water hyacinth
The presence of heavy metals in the environment due to industrial activities is of serious concern because of their toxic behaviour towards humans and other forms of life. Biosorption of Pb(II) using dry bacterial biomass of Bacillus badius AK, previously isolated from water hyacinth compost, has been undertaken in batch system. The optimum conditions of biosorption were determined by ...

Process parameters analysis for the vermicomposting of shredded paper using Pheretimoid Spp.
This study was to assess the effect of new species of earthworms, Pheretimoid Spp., on vermicomposting and compare the quality of vermicompost against compost produced from the same mix ratio of shredded office paper (SOP) together with grass clippings (GC) and cow manure (CM). Two composting experiments were setup in rotary drum composters namely: 1) composting of SOP, GC and CM followed by ...

Effects of C/N ratio on mixed organic waste composting in a rotary drum composter
Effects of Carbon to Nitrogen (C/N) ratio on the rotary drum composting of organic waste were examined by measuring changes in various parameters. It was observed that time courses of four C/N ratios: 16, 22, 30 and 38 were different. Initial C/N ratio 22 produced high-quality compost (total nitrogen-2.1%, total phosphorus-4.3 g/kg) within 20 days. While in case of C/N 16, compost yields 1.8% ...

Rotary drum composting of different organic waste mixtures
The effects of three different mixtures of organic waste on composting in a rotary drum were examined by measuring changes in physico-chemical and biological parameters. It was observed that the time courses of the three mixtures: run A (grass cuttings, vegetable waste and food waste), run B (cattle manure, vegetable waste and sawdust) and run C (cattle manure, food waste, vegetable waste, paper ...

Mixed organic waste composting using rotary drum composter
A combination of vegetable waste, cattle manure and saw dust was utilised for high rate composting in a household rotary drum composter. It was found that temperature remained above 55?C for a period of two days, Faecal Coliforms and Faecal Streptococci decrease from 7.5 ? 108 to 5 ? 102 and 1.5 ? 107 to 5 ? 103 bacteria/g, respectively. Negligible VFAs production indicated full aerobic ...
