    Abstract

    This research aims to demote BOD and COD from paper Industrial liquid waste by using sea water as coagulants. sea water contain compounds that can work as coagulants. with carry out this watchfulness us can detect how far sea water can influential toward degree depreciation BODand COD in paper waste. This researchs execution is preced with paper waste water thinning with aquadest with comparison 1 : 2 that got pH waste much as 6 then added sea water with dose that appointed in variable change then stirred with speed 100 rpm and infoemer time that appointed variable change. Furthermore precipated during 60 minutes. Afterward filtered, sediment is throwed away, while filtrate analyzed BOD and COD. Variabel change that influence among others time during 5, 10, 15, 20 and 25 minutes. besides sea water dose as big as 2%V, 4%V, 6%V, 8%V and 10%V volume waste. From this research result is got best condition when informer during 10 minutes with dose increasing coagulants as big as 2%V, with depreciation BOD musch as 1,36 mg/l and depreciation COD musch as 4,34 mg/l. Keywords: sea water, coagulants, waste
