Abstract The aim of the study was to use of rotary drum composter as a low cost method for the removal of Ascaris lumbricoides and Trichuris Trichiura in faecal sludge compost. Two runs of compost experiment (Run 1 and Run 2) were carried out consecutively. Each Run of composting was done in four different rotary drums at real scale using a mixture of faecal sludge and shredded maize cobs and monitored for 12 weeks. Concentration of Ascaris and Trichuris were measured once a week to understand their behaviour. Temperature, Moisture Content and pH were also measured. High concentrations of Ascaris and Trichuris were present in the initial compost mix of both Runs 1 and 2. The concentration of Ascaris and Trichuris respectively in Run 1 ranged from 65–77 eggs/gTS and 30–41 eggs/gTS. In Run 2, measured concentrations of Ascaris and Trichuris ranged from 77–110 eggs/gTS and 46–52 eggs/gTS. After 84 days of composting faecal sludge, Ascaris was removed by a minimum of 82% and Trichuris by a minimum of 88%. The findings showed that plastic composter with paddles performed better compared with the other experiments. This means that the type of composter have a significant impact on the removal of helminth.

Rotary Drum Composter

High rate composting studies of hard to degrade herbal wastes were conducted in a 3.5 m3 capacity rotary drum composter. Studies were spread out in four trials: In trial 1 and 2, one and two turns per day rotation was observed, respectively, by mixing of herbal industry waste with cattle (buffalo) manure at a ratio of 3:1 on wet weight basis. In trial 3 inocula was added in raw waste to enhance the degradation and in trial 4 composting of a mixture of vegetable market waste and herbal waste was conducted at one turn per day. Results demonstrated that the operation of the rotary drum at one turn a day (trial 1) could provide the most conducive composting conditions and co-composting (trial 4) gave better quality compost in terms of temperature, moisture, nitrogen, and Solvita maturity index. In addition a FT-IR study also revealed that trial 1 and trial 4 gave quality compost in terms of stability and maturity due to the presence of more intense peaks in the aromatic region and less intense peaks were found in the aliphatic region compared with trial 2 and trial 3.
