TINJAUAN ASPEK TEKNIS PEMILIHAN MEDIA BIOFILTER UNTUK PENGOLAHAN AIR LIMBAH Said, Nusa Idaman; Marsidi, Ruliasih
Jurnal Air Indonesia Vol. 1 No. 3 (2005): Jurnal Air Indonesia
Publisher : Center for Environmental Technology

There are literally dozens of different types of biofilters used for wastewater treatment applications. While many have common features, some are fundamentally different from the rest. The purpose of this article is to educate the reader about the types of packings used for fixed film biofilters.The types of biofilters under discussion are filters that employ a non-moving surface area to provide a substrate for various bacteria to attach and grow. The substrate remains in place while the water flows through the system. The heart of these biofilters is the packing or media used to provide the surface area. The type of packing used strongly influences both the capital and operating costs of the biofilter. It is important to emphasize however, that the packing merely provides surface area for bacteria to colonize. It is the bacteria that do the actual work of the biofilter. In order for the bacteria to do their job effectively, the biofilter and packing design must provide an even distribution of nutrients and oxygen while removing dissolved and suspended waste products. Most biofilters utilize aerobic bacteria but it is also possible to design and operate anaerobic systems for special purposes. Various types of packings exist for fixed film biological filters. Each different type has advantages and disadvantages but in terms of overall cost and suitability, the structured packings are the best choice for commercial biofilter designs.Ã‚Â Kata kunci : biofilter, media, pengolahan air limbah.

Rainwater is an abundant source of water, especially during the rainy season. But otherwise if it is not managed properly, it can lead to disasters, such as floods or landslides. Therefore it is very important to harness rainwater by doing the best way, ie by the rain harvesting and then infiltrating the water back into the ground. Many countries have shown good results in the use of rainwater for various purposes. Dominican Republic, Singapore, Japan, China, Thailand and Indonesia are 7 countries which have a lot of implementing rainwater utilization system very well. Rainwater can be used as a source of clean water to meet the drinking water needs. Artificial recharge for rain water lets the water goes to infiltrate back into the soil is a powerful effort to maintain and preserve the ground water potential. Besides, infiltration of rainwater into the soil also can prevent land subsidence. Because of the importance of rainwater management system, it should be included in the educational curriculum both for elementary to upper secondary level. Similarly, the obligation for proper implementation must also be supported by adequate rules or regulations.Ã‚Â Keywords : Rainwater management, artificial recharge.

Bursts of mud in Sidoarjo has caused changes in environmental quality around the bursts area. Observation in that area indicate there have been changes in air quality and odor caused by mud spurt. In addition, changes in the geological structure of land in the area around the mud spurt, has resulted some water spurt phenomenon that came from the well pump belong to some residensts in that area. This water spurt phenomenon is followed by the change of water quality which was to be used for the needs of daily living, now in some villages in the area around the mud bursts can no longer be used. To find out some parameters of water quality that arises from the some well pumps that produce big water spurt, we need to performed water quality monitoring using multiprobe digital sensors that are able to measure several parameters at once.This paper presents the measurement data of water quality in some well pumps that produce big water spurts with the YSI600R digital sensor.Ã‚Â Keywords : Perubahan kualitas lingkungan, semburan lumpur Sidoarjo, pemantuan kualitas air, sumber bubble, sumur pompa, sumur bor, separasi air dan gas, multi probe digital sensor

Jakarta Bay is a semi enclosed bay located in the northern coast of Jakarta Metropolitan City. Hydrologically 13 rivers flowing in the Jakarta region and there are three big rivers with significant discharge to the Jakarta Bay namely Citarum, Ciliwung, and Cisadane Rivers. Jakarta, as Indonesian capital city with population of 8.725.630 inhabitants, and another 15 million people live in the surrounded suburban of Jakarta, creates a significant anthropogenic impact to the environmental system. Limited infrastructures, such as no sewerage system and lack of industrial waste management, cause the rivers in this region have over their carrying capacity.Seventeen sampling stations were determined in the Jakarta Bay, consisting of 5 stations at the river mouths (estuaries) and other 12 stations in the bay spreading from the coastal to offshore areas. Water and sediment samples were taken during 2 monsoonal or seasonal variations, August 2006 for dry season and February 2007 for rainy season respectively. Additionally, samples were also taken in May 2007.Sediment distribution in the estuary consists mostly of black clay. The sediments clays were bad smell. In the coastal region and in the dry season, the sediments consists of black clay and at one sampling site (station S3) the sediment was bad smell. However, all sampling sites became bad smell in the rainy season. In the inner bay area, sediments were greyish green sandy clay with some shell fragments. In the outer bay, the sediments were dominated by greyish green clayey sand with some shell fragments. The black clay with bad smell is indicative of anthropogenic influence from Jakarta River Basin. C/N ratio of the sediments in the dry season ranged from 1 to about 4.2 where in the estuaries (at stations M1, M2 and M4) the ratio were higher compared to the inner and outer bays. The C/N ratio of suspended particulate matter ranged from the lowest ratio of 0.7 to the highest ratio of 17.7 at the bottom layer and lesser ranged of 0.7 to 9.8 at Ã‚Â surface layer. POC concentrations ranged between 50-650 Ã‚ÂµM and 50-900 Ã‚ÂµM, in February and May, respectively. High concentrations of POC exists along the coastline or estuaries then decreasing toward the sea. POC is distributed widely in February than that in May due to higher discharge from the rivers. The average TOC concentrations in February is lower than that in May, but the TOC load in February was much higher than that in May due to the big differences of river discharge and because the samples were taken a week after the big flood in Jakarta area (February 4th - 6th, 2007). Total organic carbon fluxes from the river to the bay in February and May 2007 were 107.6 T /day C and 42.7 T /day C, respectively.Ã‚Â Key words : sediment, anthropogenic influence, C/N Ratio, POC, TOC, flux

The study of assessment and implementation of Online Water Quality Monitoring System that has been done by Agency for the Assessment and Application of Technology, results a recommendation to develop a water sample systemÃ‚Â for a certain river conditions. The function of the water sample system is to pump the water from the river to a sensor tank, so that the sensor does not have to be immersed directly into the river. The purpose of this sampling system is to reduce the risks that beÃ‚Â faced by the sensor if it is immersed directly into the river. In this research, the water sample system made as a water pumping system.The water pumping system was made from materials that already existed in Indonesian market. The main components of this water pumping system are: centrifugal pump, sensor tank, water tank for the pump, and solenoid valve. The control system for the water pumping system is made from a conventional control consisting of relays and timers and is triggering by the output contact of the data logger. The water pumping systems that have been made in this research is running properly and they haveÃ‚Â a high reliability.

Development activity has been exploiting water resources (SDA) massively. Every year the number of critical watershed along with the increasing environmental degradation. Management of water resources are always either continued effort by the government to reduce the negative impact of environmental pollution. One way is to build an Information System Web-Based Coastal Rivers and can be used to determine the condition of water resources in the basin, so that the status of potential and water quality can be monitored at any time either by the government or the wider community and other civil society organizations . The information system Web-Based Coastal Rivers and can be realized by performing a data management of water resources in the basin structured through the development of Water Resource Database (DBSDA). Rivers and Coastal Information System (SISPA) Web-based was developed to assist the Ministry of Public Works in order to carry out the data management of water resources and coastal rivers in the basin in accordance with the rules established by the existing regulations, particularly the Law 7 Year 2004 on SDA and PP 42 Year 2008 on Management of Natural Resources.Ã‚Â Keywords : River and Coastal Information System, Water Resources Information SYstem, River Basin, River Basin Unit, DAS, SWS.

The population is growing rapidly result to increased demand for drinking water while the other side of this situation causes to the increasing amount of wastewater. Waste water treatment plant has been built in several major cities in Indonesia to overcome the problem of pollution.Ã‚Â Wastewater treatment plant only treats wastewater to tackle environmental pollution without being able to overcome the shortage of clean water community. Therefore, to solve the existing problems will be considered any further processing with recycled waste water treatment. One technology that may be developed for this purpose is the system of Membrane Bioreactor (MBR). This has been widely applied as an advanced unit of wastewater treatment and serves as a unit of processing recycled waste water. The MBR system has advantages such as: it only takes a little bit of land, can treat wastewater with discharge varying quality and process wastewater with high pollutant removal efficiency. MBR were investigated using a membrane filter submerged in the reactor. Membrane module is hollow fiber with a form of polymeric membrane materials. Research has been done on wastewater treatment with a combination of conventional WWTP as preliminary and advanced processing unit with MBR since March 4, 2014 until June 2014. The effluent qualityÃ‚Â of result research proved thatÃ‚Â the treated water quality meetsÃ‚Â water quality standards are set withÃ‚Â Permenkes RI N0.416/Menkes/Per/IX/1990, dated 3 September 1990. The nitrification and denitrification also proceed well so that the concentration of nitrite and nitrate meet the quality standards. In addition, the percentage removal of heavy metals (arsenic, cadmium, chromium, selenium, lead) can reach 99%.Ã‚Â Keywords: MBR, wastewater reuse, BOD5, COD, HRT dan SRT

EFFECT OF NITRITE ON DENITRIFICATION OF WASTEWATER BY AUTOTROPHIC BACTERIA Nugroho, Rudi
Jurnal Air Indonesia Vol. 2 No. 2 (2006): Jurnal Air Indonesia
Publisher : Center for Environmental Technology

Effect of nitrite on denitrification of synthetic wastewater using autotrophic bacteria was evaluated in both batch suspension and continuous packed column runs. Emphasis was placed to clarify the minimum concentrations of nitrite and nitrous acid that inhibit the denitrification rates. Batch suspension runs were conducted by mixing acclimatized denitrification sludge and synthetic wastewater in an Erlenmeyer flask. In continuous runs, denitrification sludge was loaded to a column packed with sulfur and limestone. The nitrite inhibition could be explained satisfactorily by substrate non-competitive inhibition model. The minimum concentration of nitrite which inhibits the nitrate and nitrite removal rate lowered with decreasing pH. In suspension runs, the minimum concentration of nitrous acid which inhibited the nitrite removal rate was 0.043 g-N/m3, while the nitrate removal rates was inhibited below 0.012 g-N/m3.Ã‚Â Both in suspension and continuous packed column runs, nitrate removal was more sensitive against nitrite increase compared with nitrite removal. The minimum concentration of nitrite which inhibited nitrate removal rate in continuous packed column runs was lower than that in suspension runs.Ã‚Â Ã‚Â Keywords:Autotrophic bacteria, denitrification, inhibition, nitrite, sulfurÃ‚Â
