Abstract

The textile industry is one of the most popular industries in Indonesia. Although it’s giving a positive value towards economic value, it also contributes a bed effect towards environmental quality. One of those industries is small-scale laundry industry located in Kelurahan Sukabumi Selatan, West of Jakarta. The lack of land and money, most of the jeans laundry industry throws away their wastewater straight to the river system without any process. The present study describes the application plastic media called bio-ball as a biofilter supporting media for treating of jeans laundry industry wastewater using combined anaerobic and aerobic process. The type of reactor that is used in this research is a continuous flow biological reactor which has total volume 195 litter and divided into 5 zones, i.e. presedimentation , 2 anoxic zone, aerobic zone and post sedimentation zone. Reactor effluent is recirculated into presedimentation zone with hydraulic recycle ratio (HRR) 1:1. Seeding is done in a natural way by directly flowing the domestic wastewater into reactor with retention time 72 hours, until a biofilm layer is formed on the surface of bio-ball media. Acclimatization is done gradually by replacing domestic with laundry jeans wastewater in 72 hours retention time, until domestic wastewater was 100 % replaced, The main research were conducting by continuous operation under condition 72 hours, 48 hours and 24 hours retention time. The result of experiment shows that within the combined anaerobic and aerobic process using bio-ball plastic media under conditions 1 - 3 days retention time, the removal efficiency of COD 78 – 91 %, BOD 85 – 92 %, Total Suspended Solids (TSS) 80 – 93 %, and Colour 48 – 57 % respectively.  The longer retention time has resulted in higher removal efficiency

Abstract

A biological denitrification using autotrophic bacteria in batch suspension runs was investigated to clarify the effect of pH on denitrification rate. Elemental sulfur was employed as an electron donor. The culture of autotrophic bacteria was obtained from activated sludge by acclimatization. The effect of pH on denitrification rate could be expressed by bell-shape equation with optimum pH of 7,07. However at a pH range of 5,5 to 8,0, the denitrification rate significantly fastl. Therefore, the application of the denitrification of wastewater using autotrophic bacteria is suggested running well although without controlling pH.  Kata kunci : Denitrification, nitrate, autotrophic bacteria, elemental sulfur, pH.

Abstract

Water pollution in Jakarta area, especially river and shallow groundwater, had become a very serious problem. Pollution problem caused by small industrial activities had not been got attetion. Some activities, which often cause water pollution problem, were wastewater from electroplating small industry. This wastewater was one of the most potential pollutant sources, because it contains high concentration of heavy metal pollutant such as Fe, Ni, Zn, Cr, ect. To anticipate its negative effect to the environment and social life, it needs to provide a technical standard plan to manage wastewater treatment plant, especially of electroplating small industries. The purpose of these activities is to do the assessment and application of wastewater treatment technology of electroplating small industry. The target is to get design engineering and pilot plant of wastewater treatment technology for electroplating small industry. Kata kunci : Pencemaran logam berat, Pengolahan limbah cair industri kecil pelapisan logam.

Abstract

Crude palm oil produced in Indonesia has already been known as the second largest in Asia. Unfortunately tens of palm oil factories (CPOF) spread out in Indonesia have not good wastewater treatment plants (WWTP) yet. PT. Kertajaya, as an example, which is located in Regency Pandeglang, still has BOD contained in its final effluent of the wastewater treatment plant more than 200 ppm. In fact the capacity and capability of WWTP in PT. Kertajaya are much more than enough for only 288 m3 per day. Because of improper operation and maintenance of the WWTP, the technical problems are accumulated, such as, increasing the sediment, decreasing the retention time and channelling of the wastewater being treated. The following affect is the treatment process is not going well and the quality of effluent is getting worse. To solve the technical problems, it is very important to remove the sediment periodically and give aeration in the aerobic pond. A recommendation for the wastewater treatment system has been proposed. The system has eight processes including oil separation or first sedimentation, neutralization, equalization, anaerobic degradation, aerobic degradation,  final sedimentation and sludge drying. Katakunci : BOD, technical problem, wastewater, anaerobic.

Abstract

Domestic waste are known to be a potential pollutant due to its’ organic and inorganic content. It is also harmful for society for its pathogenic microorganism contents such as pathogenic bacteria, viruses, parasitic worms, parasitic protozoa, etc. The lack of domestic waste processing facilities is contributing to the increasing seriousness of this matter.One of the alternative ways to amend the problem is to process the waste individually or semi-communally by utilizing an aerobic-anaerobic biofilter process. Some of the advantage of utilizing this process is: easy maintenance, low operation cost, relatively lower sludge compared to the activated sludge  process, can remove nitrogen and phosphorus, relatively lower air supply requirement for aeration, applicable in processing waste water with large amount of BOD and it can also remove suspended solid (SS).  Results gained from experiments of the “Aerobic-Anaerobic Biofilter Combination” tool prototype, used for processing domestic waste showed that with a hydraulic retention time of 1 to 3 days and a Hydraulic   re-circulation ratio (HRR) of 1, is a highly efficient process which is: BOD 84.7% - 91%, COD 79.6%-95.3%, SS 94.1% - 95%, Ammonia (NH4-N) 89.3%-89.8%, Detergent (MBAS) 83% - 87% and phosphate (PO4) 44,4% - 47.3%. Kata kunci : Air limbah domestik, patogen, parasit, biofilter, anaerob, aerob.

Abstract

Anaerobic treatment of synthetic wastewater with a high NaCl content was investigated for its effect on the process. The synthetic wastewater, including NaCl up to 40 g/l, was treated anaerobically by draw-and-fill method at a treatment temperature of 37℃ and volumetric loading of rate TOC of 1 g/l/d. TOC removal efficiency and rate of gas evolution rate gradually decreased as salt content increased, although stable operation was maintained. TOC removal efficiency remained high at concentration of NaCl up to 20 g/l, although it fell to 82 % at 30 g NaCl/l. The gas yield at 10, 20 and 30 g NaCl/l were 1.35; 1.10 and 1.00 l/g-TOC loaded, which corresponded to 96; 83 and 78% of that without NaCl, respectively. The content of methane in the evolved gas was 50 to 55% throughout the experiment. Stable operation could not be maintained at 40 g NaCl/l since the TOC removal efficiency gradually decreased with the rapid increased in levels of volatile fatty acidsKata kunci : fermentasi metana, garam NaCl, konduktifitas, asam-asam organik, biogas

Abstract

Evaluation of chloride (Cl-) content and electric conductivity  (EC) of ground water in aquifer system is one method to identify salt water movement in aquifer system, which occurred as a result of changes in hydraulic equilibrium which cause by temporary variation of natural recharges and pumping of ground water at many layered aquifers.Salt water movement in Jakarta aquifer system is evaluated based on mapping of chloride content at 500 mg/L and EC at 1500 m mhos/cm in many bored well during period of 1990 – 2000. In the beginning chloride content and EC is in value only and with the addition of attribute data, namely coordinate, it could be used as input data. By using software namely SURF, the above input data is simulate to have a contour map of chloride and EC. Overlapping of the contour map to Jakarta base map will result in thematic map of chloride and EC distribution which represent salt water movement at Jakarta aquifer system.   Key word : Aquifers, Aquifer system, Chloride (Cl-) , Electric Conductivity (EC), Map, Hydraulic Equilibrium, Ground water, SURF Software.

Abstract

Biofilter as one of method processing of waste have been introduced since early 20, but in its application have time to be left by effect of newer technological appearance like trickling filter, rotating biological contactor, activated sludge, and fluidized bed reactor. Biofilter very effective in deodorizing, especially dangerous aromas of organic volatile compound, and poisonous air from industry with efficiency 90 - 99,9%. Biofiltrasion become more economic compared to carbon adsorption or oxidation when its organic content under 3000 ppm. Most biofilter operate on organic concentration around 1000 ppm or  lower. There are some matter to influence market of biofilter, for example :        1). the increasing of regulation about oxide nitrogen emission coming from hot process. Biofilter do not yield nitrogen oxide addition, 2). The increasing of sigh of society about contamination of aroma of facility processing of waste, processing of solid waste and others, 3). preventive methodologies implementation of pollution using condensation and air emission concentration, 4). Pressure to industry to use processes with discard as small as possible, 5). The increasing of attention to emission of hit and organic air materials, and also low cost water treatment technology.   Kata Kunci  : Bau, Odour, Biofilter, Biofilm, Limbah tahu dan tempe, wastewater treatment
