Abstract-The lab scale upflow anaerobic sludge blanket reactor UASB seeded with cow dung manure was used to treat the waste water from M Dasan Institute of technology having medium strength. The cow dung seed sludge required a period of 120 days for acclimatization and the sludge bed of the reactor was stabilized in a period of 20 days and the reactor was continuously working for a period of 56 days. The physicochemical and biological parameters of waste water quality are experimented and found out and design of lab scale reactor and design of proposed UASB reactor was done .pH of effluent increased with time and ranges from 4.4 to 7.62.Turbidity of effluent decreased with time and it has a percentage removal of 72.4.Conductivity of effluent decreased with time and it has a percentage removal of 84.51.TDS of effluent decreased with time and it has a percentage removal of 85.99.BOD of effluent decreased with time and it has a percentage removal of 77.95.COD of effluent decreased with time and it has a percentage removal of 82.38.Chloride of effluent decreased with time and it has a percentage removal of 81.26. All the values were within permissible limits of discharge as per E (P) rules, schedule VI part A.

Keywords-UASB reactor, BOD, COD, pH, Turbidity, Conductivity

I. INTRODUCTION

As our college, M Dasan Institute of Technology (M-DIT) Ulliyeri is newly established in 2012, no waste water treatment plant is designed for the treatment of waste water generated from our campus yet. In the beginning years, the student population was few when compared to today’s scenario so that waste water generated was less and it was not considered to be a pollution.
