BIODEGRADATION REMAZOL BRILLIANT BLUE IN VERTICAL FILTRATION SYSTEM WITH INOKULUM BACTERIA FROM DIED SEDIMEN RIVER IMAM BONJOL DENPASARThe biodegradation research of Remazol Brilliant Blue (RBB) has been done in vertical biofiltration systems with bacterial inoculum that had seed from soil Mati River Imam Bonjol Denpasar. This aims of research are to obtain the best active suspension grown from soil samples of Mati river sediment and to determine the magnitude of the effectiveness and capacity of biosystem . The artificial waste water of RBB has made with a concentration of 200 mg/L. In the first phase, the best active suspension is obtained by determining the value of VSS ( Volatile Suspended Solid ) is the highest as a source of inoculum of bacteria capable of degrading RBB. While the second phase, the effectiveness and capacity of biosystem is obtained by determining the levels of waste of artificial RBB vertical biofiltration system (biosystem). Biofilm has made with attached bacteria consortium in volcanic rock for 7 days. RBB subsequently incoporated into it to determine the concentration of it and to determine the effectiveness and capacity and identified the bacteria contained in biosystem. The results showed the best sludge active from soil sediments of the Mati River Imam Bonjol Gang Keladian with a value of Volatile Suspended Solid (VSS) highest of 17200 mg/L when the sreeding time of 48 hours. The results of processing using biosystem known to decreased when the processing time from 6 hours up to 114 hours, from concentration of 200 mg/L to 19.6211 mg/L. Then the prosses has increased again into 19.8209 mg/L at the time to 120 hours. The highest effectivity of biosystem to degrading remazol brilliant blue of  90.19 % for 114 hours , while the highest capacity is obtained from the biosystem is 1.6525 x mg /g for 114 hours. The bacteria that act to decreased identified as Pseudomonas sp., Aeromonas sp . and Plesiomonas sp, with Pseudomonas sp more dominant in the  degrading of dye RBB.

The aim of this research is to evaluate the feasibility of the fibrous media for removal of total suspended solid and oil grease from palm oil mill effluent (POME). Wet lay-up method was adopted for filter fabrication where empty fruit bunches (EFB) were matted together with chitosan in non-woven manner. Chitosan-filled filter media were tested for their ability to reduce Total Suspended Solids (TSS) and Oil & Grease (O&G) from palm oil mill effluent. Filtration process results indicated that chitosan-filled filter media filtration only removed up to 28.14% of TSS and 29.86% of O&G.

Low concentration synthetic and municipal wastewaters were treated at HRT as short as 3 and 0.6 h respectively in an anaerobic inverse fluidized bed. Both bioreactors showed gas hold up due to the liquid downflow pattern of the prototype. The bioreactor operated at 3 h had a removal efficiency of 83%, specific activity of 4.5 kg CODremoved/kg IVS (d and the gas hold up varied from 23 to 55%. The reactor treating municipal wastewater had a removal efficiency of 44% when operating at 0.6 h, the specific activity was 4.2 kg CODremoved/kg IVS (d and no biogas was detected apparently because an important fraction was dissolved in the liquid phase. The biomass concentration was 13.8 and 1.1 kg IVS/m3 for synthetic and municipal wastewater and the SEM microphotographs showed a bacterial diversity for the first run and only cocci cells for the second run. The system does not remove suspended solids, so a polishing postreatment to improve water quality has to be implemented.

A pilot plant of SBR (Sequencing Batch Reactor) and MF (microfiltration) process was operated in order to treat and reuse the greywater produced from an office building. The performance of SBR for greywater was satisfactory as the effluent had 20 mg/l, 5 mg/l, and 0.5 mg/l of SCOD, BOD, and ammonia, respectively. The cyclic operation of SBR used in this study proved more effective in nitrification and denitrification than the conventional SBR operation. However, the most effective mode was step-feed SBR for denitrification. The decanting system of this SBR discharged the effluent fairly well without sludge washout. However, it was difficult to maintain constant concentration of suspended solid from the SBR process. Thus, additional filtration was needed to get adequate water quality for water reuse. MF could remove residual suspended solids and pathogens as well from the SBR effluent. The suspended solids of final effluent were around 1 mg/l and allowed using the treated water for some purposes.

Growing of mankind, society, science and technology in our world is reaching to higher level of human civilization. Therefore, a sustainable treatment procedures are required in order to prevent the consequences of growing civilized situation to the environment. Magnetism has been used as physical treatment for particles or contaminants removal from wastewater. In this experiment, comparison between locations of steel wool has been carried out in order to determine the highest suspended solid removal. Variables has been set such as magnetic strength was 1.4Tesla, flow rate was 1mL/s, 80 gram of steel wool and experiment took 24 hours of circulation time and data recorded for 24 hours. Data were recorded involving control, non-inverted magnet and inverted magnet structure. Non-inverted magnets consists of magnets on same poles while inverted magnet on different poles. As a result, steel wool located inside of pipe was exhibited the highest removal (88.2%) compared to outside of the pipe (83.3%) and both occurred in inverted magnet structure. Therefore, it was indicated that longer exposure time to magnet resulted in greater improvement in removing pollutant. The results obtained and suggests that steel wool located inside of tube with inverted magnet position can be successfully treat wastewater effectively.

The performance of an Expanded Granular Sludge Bed (EGSB) reactor for treating slaughterhouse wastewater under mesophilic conditions (35°C), was investigated. The reactor was inoculated with granular sludge from an anaerobic reactor of a brewery factory. The averaged COD removal percentages were 67% for total organic loading rates (BV.TCOD) up to 15 kg COD m−3 d−1 and a hydraulic retention time (HRT) of 5 h. Total suspended solids (TSS) were 90% removed for total solids loads of 6 kg TSS m−3 d−1. Fats were 85% removed and no accumulation of fats on the sludge was observed. The specific methanogenic activity of the sludge, after 140 days, was about three times higher than the sludge inoculated into the reactor. The sludge activity did not significantly change after one year of work. These findings indicate that the anaerobic treatment of slaughterhouse wastewater in an EGSB system appears to be a feasible option.

The use of conventional flocculants such as Aluminum sulphate (Alum) alone to treat the wastewater may be insufficient to get the required turbidity, suspended solids removal as well as it requires relatively a long residence time. Magnetic flocculation is one of the used techniques for increase the efficiency of the turbidity removal. In the present study, three sets of experiments are carried out in order to investigate the possibility of increasing the suspended solid removal efficiency from Al Doura oil refinery wastewater using iron oxide (Fe3O4), Nickel (Ni), and Cobalt (Co) ferromagnetic powders with alum. The following operating conditions namely, pH, alum dose, ferromagnetic powder dose, and initial turbidity are studied. The results revealed that an improvement in turbidity removal efficiency is satisfied, as well as, a reasonable reduction in the sedimentation period is achieved. The highest turbidity removal is 99.88% that obtained for 122NTU sample for alum dose 120 mg/L+ Nickel dose of 80mg/L and pH of 6.5.

This experiment aimed to determine the plankton community structure in intensive and traditional ponds of  Probolinggo Regency, East Java Province. Plankton collected with plankton net size of 60 μm and preserved with lugol 1%. Water qualities such as temperature, transparancy, salinity, dis-solved oxygen, pH, total organic matter, NO2-N, NO3-N, NH3-N, PO4-P, and total suspended solids were measured and analysed in this study. Planktons were identified using microscopy. Cells were counted using cell counting method. The results showed that in intensive pond we found 16 species of phytoplankton and 7 species of zooplankton with abundance 570-1.808 ind./L, while in traditional ponds, we found 10 species of phytoplankton and 3 species of  zooplankton with abundance  134-776 ind./L. The dominant species of phytoplankton in the intensive and traditional ponds were Navicula sp andNitzschia sp, each of Bacillariophyceae class with abundance of 423 ind./L and 198 ind./L, res-pectively. Zooplankton species in intensive pond was copepod sp, while in traditional  one was Oitho-na sp, each of Crustaceae class with abundance of  66 ind./L and 37 ind./L, respectively. Diversity and abundance of plankton in intensive pond was higher than in the traditional ponds. The water quality in intensive pond was optimal so that the response to the absorption of  N and P inorganic by phyto-plankton was quicker and more effective than in traditional pond producing an increase in plankton communities. The increase value of NO3-N and total suspended solids in intensive pond caused the in-crease abundance of Navicula sp.  The high value of NH3-N caused the abundance of Navicula sp to decline. The high values of dissolved oxygen, pH, total suspended solid, and NH3-N in traditional pond can decrease the Nitzschia sp abundance.  Keywords: plankton communities, intensive and traditional ponds, Probolinggo, East Java
