Abstract

Seawater intrusion causes groundwater in coastal areas to be brackish, so it requires special processing to remove salt levels in raw water so that the water becomestasteless. In addition to salinity, the presence of bacteria in water can cause disease if consumed without proper processing. Brackish water treatment called desalination can be done by ion exchange using an activated carbon filter. The purpose of this study was to determine the efficiency of the performance of brackish water processing filters in setting aside water quality parameters in the form of: coli bacteria and total bacteria expressed in the Total Plate Count (TPC). The filtration reactor is made using filter media in the form of activated charcoal (20 cm), silica sand (15 cm), zeolite (15 cm), and gravel (10 cm). laying the reactor upright and tilted 45 degrees. The results showed that the reactor filter was effective in reducing Coliform bacteria and total bacteria in raw water up to 100% and 97%, respectively, although it did not meet drinking water quality standards PERMENKES No.492/Menkes/Per/IV/2010. Both reactor variations have performance effectiveness that is not significantly different in processing raw water, but overall reactors with upright variations have better performance. Keywords: Active Carbon Filtration, Coliform, Total Plate Count.

Abstract

Leachate can be formed from the percolation of water that passes through the garbage. The high content of organik and metallic substances in leachate can cause environmental damage, so it must be treated first before being discharged into the environment. This study aims to determine the effectiveness of ozonation in neutralizing pH and reducing the levels of TSS, BOD, COD in the leachate of the Griyo Mulyo landfill using the AOPs method based on ozonation. Studies on ozonation in leachate treatment have been carried out by varying the ozonation time (15, 30, 45, and 60 minutes). Parameters that have been observed are pH, TSS, BOD, COD. The results showed that the best ozonation time for leachate pH was at 15 minutes with a value of 7, the best ozonation time for leachate TSS was at 15 minutes with a value of 56 mg/L. The best ozonation time for BOD and COD was at 45 minutes with values ​​of 511 mg/L and 1260 mg/L, respectively.  The best percentage of removal efficiency for TSS, BOD and COD reached 67%; 84.1%; and 88.41%.

Abstract

Jetis Batik Village is a Sidoarjo batik center that produces typical Sidoarjo handwritten batik. The batik processing process produces textile waste which must be processed before being discharged into the environment. Many producers, both large and household scale, have one thing in common, namely producing liquid waste, containing dyes, suspended solids, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), Total Dissolved Solids (TDS) that need to be managed before being discharged into water bodies. One way of processing that can be done is by using adsorbents. Lapindo mud and Blood Clam shells are abundant natural materials that can be used to process textile waste. Varying adsorbent mass ratios were carried out to determine the optimal adsorbent ratio for processing textile waste. Variations in mass of Blood Clamshells and Lapindo mud (1:0, 0:1, 1:1, 1:2, 2:1). The best variation in reducing COD was variation C (1 g Lapindo mud and 1 g Blood Clam shell) with a removal efficiency of 89.13%. The best variation in reducing TDS is variation E (2 g Lapindo mud and 1 g Blood Clam shell) with an efficiency of 86.07%. The TSS removal efficiency showed relatively the same results 33.33%.
