Abstract

Research on seaweed effluent treatment through biofiltration of artificial ecosystem was carried out to determine the effectiveness, capacity, and the minimum duration of biofiltration process to reduce COD, nitrate and pH in water to meet the quality standard. The result shows that effectiveness of treatment system without added microorganisms are 79.22% for COD, 38.77% for nitrate, and 35.64% for pH; whereas, by adding microorganisms are 83.93% for COD, 55.54% for nitrate, and 36.43% for pH. Capacity of the treatment system without added microorganisms are 12.0653 mg/L/m3hr for COD, 0,0089 mg/L/m3hr for nitrate, and 0,1444 hr-1 for pH; while, by adding microorganisms are 12,7819 mg/L/m3hr for COD, 0,0129 mg/L/m3hr for nitrate, and 0,1413 hr-1 for pH. Requisite minimum time in treatment system to meet the quality standard without added microorganisms are 48 hours for COD, 8 hours for nitrate, and 8 hours for pH; whereas, by adding microorganisms are 40 hours for COD, 8 hours for nitrate, and 8 hours for pH.

Abstract

This research was conducted to study the potential of the plants ‘useless’ as kiambang(Salvinia natans) which are easy to find, and not as valuable as textile dyeing waste handlingmedia. Treatment technique used is to replace the growth medium with the waste in questionin this case of waste taken in the dyeing industry. The concentration of methylene blueinwaste of  dye, and congo red, before and after treatment, determined by spectrophotometry.Fluid absorbance was measured at a wavelength of 664 nm for methylene blue and 496 nmfor congo red. Long time treatment used is 6, 12, 18, 24, 30, 36, and 48 hours. These resultsindicate that kiambang (Salvinia natans) is useful to lower BOD and COD of waste dyeing,although its ability to reduce the content of the dye congo red and blue methyl insignificant.This may be caused by too concentrated the dyeing waste.
