Abstract


Experiment on disposal of spent wash (Vinasse) by composting with press mud cake (PMC) through microbial consortium treatment by pit and windrow system was conducted at Dnyaneshwar Sahkari Sakhar Karkhana (S.S.K.), Bhende, district Ahamednagar of Maharashtra, India. The compost prepared by windrow and pit methods from PMC and spent wash using microbial culture within 45 days ranged C: N ratio from 10.19:1 to 13.88:1 and 14.32:1 to 22.34:1, respectively. This indicated the effectiveness of microbial decomposing culture on production of good quality compost in a short period of time. Both the methods gave the higher nutritive manurial values after completion of process of composting. The compost obtained in various treatments by windrow method contained 1.52-3.7 % N, 0.9-3.54 % P2O5, 1.95-3.45 % K2O, and had pH range from 7.02-7.82. Similarly the compost obtained in various treatments by pit method contained 1.34-2.85 % N, 0.30-0.72 % P2O5, 2.20-4.72 % K2O, and had pH range from 7.40-8.16. Microbial consortium used in the present investigation included phosphate solubilizing fungi and Burkholderia species isolated from the sugarcane and sugar beet rhizosphere. Due to microbial process and aeration, both BOD and COD values were reduced substantially. Microbial population was higher in compost from windrow system as compared to in compost from pit method. On the basis of result obtained, it was concluded that windrow system of composting was better than pit method. Effluent utilization which poses environmental problem can be safely and effectively solved by this technology through microbial consortium treatment.
