Abstract

Moving Bed Biofilm Reactor (MBBR) is a biological processing technology with two microorganism culture processes, namely inherent growth and suspended growth. Microalgae Chlorella sp. is one microorganism that can be used in biological processing. Microalgae can stick to the surface of the media because microalgae produce extracellular soluble Algae Products (SAP) consisting of proteins and polysaccharides that are useful in the process of attaching microalgae to the surface of the bio carrier media. This study aims to set aside the parameter of ammonia in domestic wastewater. In this study, the media used were made of spiral hoses and plastic straws with a length of 10 mm and a diameter of 12.7 mm. Processing with MBBR uses variations in media volume that is 15%, 30%, and 45% and with variations in contact time 0, 1, 3, 5, and 7 days. The results showed the highest removal efficiency of ammonia in 30% media volume variations on the 7th day respectively 89.82%.Keywords: Biocarrier, Chlorella sp., Domestic Liquid Waste, MBBR

Abstract

The need for clean water is needed by various groups of people. People who live on the banks of the Siak River in Limbungan Village, Rumbai Pesisir Sub-District use Siak River water for clean water of bathing, washing and latrines by used it directly. Siak River water used by residents has several parameters that exceed the quality standard so that the use of river water must be processed first. One simple system that can process Siak River water is a slow sand filter with the addition of zeolite. The purpose of this study was to determine the efficiency of decreasing turbidity parameters by slow sand filters. In this study variations in the diameter of silica sand – zeolite (0,15 – 0,35) mm, diameter of silica sand – zeolite (0,35 – 0,55) mm and variations in flow rate filtration on slow sand filters (0,1 ; 0,2 and 0,3) m/hour. Based on the results of the study, the highest removal efficiency was found in slow sand filter reactors with media diameters (0,15 – 0,55) mm and with flow velocities of 0,1 m / hour, removal of turbidity is 97,08%Keywords: Slow Sand Filter, Silica Sand, Zeolite, Siak River Water

Abstract

Peat water has characteristics which are: maroon, content high organic matter and the iron also high enough, the taste is sour with pH 3-5, and low hardness (Idaman, 1999). Generally, people who live in areas such as Kabupaten Kampar are difficult to obtain clean water because only water from the river that exist which is peat water, so they use the rain water for daily needs, even though some of them use Mineral Water (Branded Water Gallon ) with the expensive price. During the dry season, people forced to use the peat water for daily needs such as cooking, washing, and toilet. If it is done continuously, it will cause disruption to health such as skin diseases, diarrhea, and others. In this research, an attempt has been made to peat water change into clean water using Multi-Soil-Layering method (MSL). The variable in this research is an organic material in an anaerobic layer which is an active banana peel charcoal and active coconut shell charcoal. This research aims to determine the efficiency of removal parameters pollutant, such as: pH, turbidity, and Mn on peat with MSL method, to study the influence of variation of organic material in the soil mixture in the anaerobic layers and variations of Hydraulic Loading Rate (HLR) to the efficiency water treatment peat with MSL method, and compare the results with PERMENKES No.416 of 1990 about Monitoring Terms and Water Quality and Regulation No. 82 of 2001 on Water Quality Management and Water Pollution Control. Optimal results which is obtained in the HLR 500l/m2days are pH from 6.51 to 6.82, Mn Metals, and turbidity decreased from 1.277mg/l, 44.56 NTU into 0.500mg/l, and 3.18NTU.Keywords:WaterPeat, MultiSoilLayering, Hydroulic Loading Rate, Variation Organic Material

Abstract

The Levels of Mn are metals in the ground water. The high levels of Mn in ground water can be processed using either advanced technology or simple technology. One technology that can be applied to set aside Mn is aeration. Aeration is the addition process of oxygen into the water to make oxidation reaction of Mn which then will cause sediment MnO2. The aim of this research is to study the cascade aerator ability in removing Mn levels in groundwater with variation of discharge 50, 60, 70, 80, 90 ml/s and the addition of activated carbon. Then calculate the value of gas transfer coefficient (KLa) in aeration process using cascade aerator. Mn levels before aeration of 0.4 mg/l for Mn. The results showed that the highest removal efficiency of Mn occurred at optimum discharge 90 ml/s using activated carbon with efficiency of 99,2%. While the lowest efficiency occurred at 50 ml/s discharge without activated carbon with efficiency of 94.6%. As well as the highest gas transfer coefficient value obtained in the experiments of 90 ml/s of 0.046/min.Keywords: aeration, cascade aerator, manganese (Mn), activated carbon, discharge, gas transfer coefficient (KLa)

Abstract

Tofu is a domestic industry developed rapidly in indonesia. Unfortunately the treatment of wastewater has not been done before the wastewater is thrown away to receiving water bodies. Therefore it is one of the causes of water pollution that effect the death of aquatic biota. Thus it is needed to do acute toxicity test. The goal of the research are to know the value of LC50 and to analyze the relationship of industrial wastewater of tofu UD. Tahu Jaya towards the experimental animal. Acute toxicity test is done by renewal test method in 96 hours using Daphnia Magna. The characteristic consentration of wastewater of tofu UD. Tahu Jaya is COD 4750 mg/l, TSS 2100 mg/l, ammonia 5,29 mg/l, pH 3 and temperature 33°C. Based on the result of analysis characteristics of tofu wastewater, it is known that the parameters of COD, TSS, ammonia, pass the quality standart of the rules of Enviromental Ministry No. 15 Year 2008 about the Quality Standart of Waste Water for Industry and Soybean Processing Activity. The value of LC50 is 6,509% and TUa (Toxicity Unit Area) of tofu industrial wastewater is 15,36 showed that the wastewater of tofu is very cause acute toxicity.Keywords: daphnia magna, LC50-96 hours, renewal test, tofu wastewater

Abstract

Sludge waste paper processing industry has a COD concentration reached 45,000 mg / L. When discharged directly into the water, it can pollute the environment because of the quality standards set by the government through KEPMEN LH No. 51 1995 which is the COD of 350 mg / L. This study aimed to reduce levels of COD in wastewater using an anaerobic bioreactor hybrid combining two patterns of growth of the microorganisms suspended on the insulated and attached growth media using the stones as cell immobilization. This study took place in four stages. The first stage is the seeding done by adding 200 mL of waste and provides nitrogen every day and lasts for 10 days. The second stage is using the method of acclimatization waste and dispose of the liquid contents of 200 mL and restocked with a substrate of 200 mL per day. The third stage is a start-up using the substrate that enter into the inlet tank, then the feed flows rate of 4L / day flow through the inlet pipe so that the entry into the reactor, the suspension in the reactor will be decomposed by microorganisms resulting in the formation of biogas. The fourth sage anaerobic bioreactor hybrid continuous with variable feed flow rate is 20 L / day, 10 L / day, 6.67 L / day, 5 L / day, 4 L / day, with a working volume of the bioreactor 20 L / day. The results showed that the removal efficiency of each flow rate was 94.44%, 94.44%, 94.44%, 94.44%, and 94.44% respectively and the average biogas production reached 1153,95 mL. Thus the hybrid bioreactor be one of the alternatives that can be used in treating wastewater which has quite high organic content.Keywords: Anaerobic bioreactor hybrid, rock, sewage, COD, biogas formation.

Abstract

The presence of Chromium (Cr) in electroplating wastewater is a major environmental problem. That toxicity and non-biodegradable where should be eliminated from water. Chlorella sp immobilized in calcium alginate is one of technology that can reduce the concentration of Cr in the electroplating wastewater quickly and without produced sludge. The data were analyzed using AAS on variation cell density in alga beads (0; 1,53x108; 1,76x107; 1,54x106 cells / beads) and contact time (0, 12, 24, 36 and 48 hours). The result showed that the highest removal efficiency of Cr occured at cell density 1,54x106 cells/beads and contact time 48 hours with efficiency of 52,04%.Keywords: biosorption, microalgae, Chlorella sp, cell density, contact time, Cr, electroplating wastewater
