Design of a Batik Coloring Waste Treatment Tool Using the Electrocoagulation Method with a Capacity of 50 Liters

Batik coloring still uses synthetic dyes, so the disposal of waste should not be careless. Most batik craftsmen process their by settling liquid for a long time. The is very ineffective. purpose this research to design processing tool that cheap and effective. method electrocoagulation method. an electrochemical water treatment. treatment consists five parts including: (1) Electrocoagulation Tub, (2) Skimmer, (3) Electrode, (4) Sand Filter, (5) Studge Drying Bed. This works with 900 watts power output 20-40 volts DC. capacity 50 liters. Duration 2 hours. able reduce values BOD5, COD, TSS, TDS in dye waste. pH wastewater which high can reduced giving alum.
