Abstract

The treatment process of wastewater contains organic pollutant which used in Indonesia especially in Jakarta is generaly activated sludge process. The problem is its treated water quality which frequently does not yet fulfilled to effluent standard of wastewater. Some affecting factors  are hydraulic retention time (HRT) too short, the fluctuation of wastewater flow rate, unfavorable function of aeration process and also which do not less important is operational mistake caused by insufficient knowledge of operator. To overcome the mentioned problems it is needed technological innovation to increase efficiency of wastewater treatment process especially activated sludge process. Moving Bed Biofilm Reactor (MBBR) technology is one of the  effective alternative for treating wastewater containing organic pollutants. In principle, MBBR is a modification of the activated sludge process is enhanced by adding the media into the aeration tank.This paper describes the study of domestic waste water treatment  using MBBR process which is filled with bioball plastic media which has specific surface 210 m2/m3 as much as 20 % of the volume of the aeration tank for attaching microorganism to increase efficiency and  keep stability of process.Result of the study shows that within 12 hours, 8 hours, 6 hours and 4 hours of hydraulic retention time (HRT) in aeration tank and sludge circulation ratio 0f R = 1.0 Q, the removal efficiency of ammonia were 94.05 %, 93.42 %, 89 %, and 79.6 % respectively. In ammonia loading 0.106 – 0.302 kg/m3.day, the removal efficiency of ammonia were 95.54 – 83.01 %. The greater ammonia loading,  removal efficiency of  ammonia  is getting smaller. Optimal residence time is 6 hours with ammonia removal efficiency reached 89 %, and the average concentration of ammonia in the effluent of 8.3 mg per litre.  Keyword : Domestic wastewater, ammonia, bioball, MBBR.

Abstract

Ariobimo building, now has a domestic wastewater treatment plant which is equipped with the system re-use. At first, the process of wastewater treatment technology using activated sludge process, while the system re-use of wastewater using a combination of chemical-physical processes, namely the process of coagulation-flocculation followed by sedimentation, filtration and adsorption last with. Because this process is not optimal, then this WWTP outlet and the quality of its water re-use can not meet the expected quality standards. After the improvement of the existing activated sludge process, the quality of this WWTP outlet can meet the quality standards of waste discharges. While the process of coagulation-flocculation is replaced with biofilter process using  honey comb tube media, the quality of the effluent can meet water quality standards. Keywords :Domestic wastewater,process modification,  water reused.

Abstract

Groundwater is water that occurs naturally in the subsurface, and is contained in the aquifer. Groundwater is the water source of the most widely used by the public for purposes of clean water. To determine the condition of the aquifer configuration one of the methods that can be used is the 2D electrical resistivity. Exploration drilling is one effective way to determine directly the presence of groundwater, but to determine the location of the drilling necessary geophysical approach to describe subsurface conditions prior to drilling. 2D electrical resistivity method is a geophysical method that utilizes dynamic electrical properties of the media path. 2D electrical resistivity measurements have been carried out in Kapuas, Central Kalimantan using Wenner configuration, the distance between the electrodes 10 meters, penetration depth reaches 80 meters, and and measuring some 21 track. Water potential zones were identified based on having resistivity range 15-25 ohm.m, contained in the sandstone layer, which is covered in a layer of impermeable mudstone layers. Location that has a high potential for groundwater recommended drilling done on the track P-07 and P-13, with an estimated depth of the aquifer between 25 meters and 30 meters. The highest groundwater potential lies between the drilling data PH-23 and PH-24, with the resistivity at that point reaches 300 ohm.m. Keywords : Groundwater, aquifer, sandstone, 2D electrical resistivity, resistivity, Kapuas

Abstract

Ground water is water located beneath the ground surface in soil pore spaces and in the fractures of lithologic formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. Ground water is alternative water to meet a demand of water supply, because the availability of surface water at an area is sometimes not enough to fulfill the need of drinking water, like occured in the Handil Babirik area. In this paper will be discribed concerning application of imaging resistivity technology for understanding characteristic and condition of ground water in Handil Babirik, Tanah Laut district, SouthKalimantanProvince. The result of survey in field, data processing, modelling and interpretation indicated that the existence of aquifer in Handil Babirik area is occupied between 30 – 40 meter depth and having a form of lens. Keywords : Handil Babirik, ground water, imaging resistivity

Abstract

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.  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 quality  of result research proved that  the treated water quality meets  water quality standards are set with  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%. Keywords: MBR, wastewater reuse, BOD5, COD, HRT dan SRT
