Abstract

Anaerobic treatment of wastewater with high organic and salt content but low pH (TOC, 14 g/l; salt, 150 g/l; pH,2.7) generated during an “ume boshi” manufacturing process was investigated. Five-fold-diluted “ume boshi” effluent was treated by a draw-and-fill method at a volumetric TOC (total organic carbon) loading rate of 3.0  g/l/d with a TOC removal efficiency of 75%. Five-fold-diluted “ome boshi” effluent was also treated in an anaerobic fluidized-bed reactor (AFBR) at a maximum volumetric TOC loading rate of 3.0 g/l/d, which gave almost the same results as the draw-and-fill method. However, ten-fold-diluted “ome boshi” effluent could be treated in the AFBR at a maximum volumetric TOC loading rate of 11 g/l/d with a TOC removal efficiency of 85%. The methane content in the evolved gas was high, being 70%. The red pigment in the “ome boshi” effluent was completely decolorized by the anaerobic treatment.  Key words :, Anaerobic fluidized-bed reactor, “Ume boshi”Co2+ and Ni2+ ions, decolorization

Abstract

An autotrophic denitrification system was developed for treatment wastewater from steel industry. The aim was to evaluate the kinetics and capability of the system in reducing nitrate content in such industrial wastewater. The experiments were conducted in batch suspension and continuous runs. The denitrification kinetics in suspension runs obeys first order reaction with the rate constant k1 and k2 were determined to be 0.014 and 0.004 g-N/m3.d, respectively. The continuous runs used a column packed with mixture of granular sulfur and limestone. The microbes of Thiobacillus denitrificans were attached on the surface of granular sulfur in the form of biofilm. The biofilm thickness was investigated to be approximately 40 μm. The denitrification kinetics in the packed column obeys half-order reaction with the rate constant k of 0.172 g-N1/2.m1/2/(kg-S.d). The lower denitrification extent of industrial wastewater compared with the synthetic wastewater might be due to the lack of alkalinity. Keywords: Autotrophic denitrification, sulfur, packed column, thiobacillus denitrificans.

Abstract

Industry is a potential source of water pollution, it produces pollutants that are extremely harmful to people and the environment. Many industrial facilities use freshwater to carry away waste from the plant and into rivers, lakes and oceans. Inorganic industrial wastes are more difficult to control and potentially more hazardous Industries discharge a variety of toxic compounds and heavy metals. The most pollutans heavy metals are Lead, Cadmium, Copper, Chromium, Selenium, Mercury, Nickel, Zinc, Arsen and Chromium. Heavy metals are dangerous because they tend to bioaccumulate. Mercury for example, causes damages to the brain and the central nervous system, causes psychological changes and makes development changes in young children. Normally Mercury is a toxic substance which has no known function in human biochemistry.There are several methods to eliminate or remove heavy metals in water such as chemical oxidation process, ion exchange process, adsorption process, an electrochemical process, reverse osmosis process and other alternative methods likes biosorption. Each method has strengths and weaknesses, therefore to choose the method of removing heavy metals in wastewater depending on pollutants conditions such as concentrations of heavy metals in wastewater, types of heavy metal, heavy metal concentrations in treated water, land availability, flow rate of wastewater will be processed and other parameters. In this paper discusses several methods of removal of heavy metals in industrial wastewater such as chemical precipitation and oxidation processes, adsorption and ion exchange process. Keywords : water pollution, heavy metal, industrial wastewater, removal methods

Abstract

Regional Drinking Water Company (PDAM) of County Ogan Komering Ilir has two problematic water treatment units. The first is located in Danau Teloko and the other is in the Teluk Gelam. The main problem is that many organic pollutants (namely peat water) contained in raw water. Therefore, PDAM can not be optimal to supply all the needs of drinking water for the community. PDAM have tried to treat the raw water of peat with the process of flocculation and coagulation, but the results did not meet quality standards as drinking water. This research is a trial test to obtain the optimum condition for flocculation and coagulation processes in water treatment. The results were very succesful and get the optimum pH is about 7.5 and a chemical dose of 80 ppm Aluminum Sulphate as the coagulant. Turbidity of water produced is 4 NTU and visually looks very clean. Better to add a synthetic polymer (PAC) as an additive to the process of flocculation and coagulation. Based on calculations, PDAM Danau Teloko will require the amount of coagulant (Aluminum Sulphate) 138.24 kg per day to produce 40 liters of drinking water per second. Keywords : Raw Water, Flocculation, Coagulation,  Water Treatment Plant

Abstract

More than 90 % of Jakarta livestock supply, especially poultry, originated from outside the area. Meanwhile temporary places and slaughterhouse are spread out in some locations in Jakarta area, even most of them located in residences area. Almost all wastewater are not processed but straightly discharged to the sewer or river around the house. These spread chickens slaughterhouse activities caused environmental pollution which is difficult to control.This paper discussed about the design of wastewater process installation of chickens slaughter by biofilter anaerob-aerob process and test of its process result. Based on the test the removal efficiency of COD, Permanganate, BOD and Total Suspended Solid (TSS) were 86.52 %, 82.85 %, 88.79 % and 94.1 % respectively.. Keyword : Design, process, wastewater, chicken slaughterhouse, biofilter.
