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

Acid Mine Drainage (AMD) treatment systems can be broadly categorised as either active or passive systems, which differ according to their ability to handle Acidity, flow rate and Acidity Load of the influent AMD.  Most passive and active systems utilise aggregate carbonate to neutralise the pH and encourage precipitation of metals as hydroxides or sulphide minerals.  In addition, passive treatment systems often use organic matter to provide alkalinity and create reducing conditions which favour the precipitation of metal sulphides.Active treatment systems can be engineered to accommodate essentially any acidity, flow rate and acidity load. Active treatment of AMD can be achieved using fixed plants or portable equipment for in-situ treatment. Passive treatment systems are almost invariably used for post closure treatment scenarios, and are best suited to AMD with low Acidity and low flow rates. The key factors in selection and design of active and passive AMD treatment systems are water chemistry including pH, metals, sulphate levels and redox state and flow rate of influent AMD, and the objectives of AMD treatment. Other important factors include capital and operating costs, availability of suitable treatment reagents or materials and sludge management issues. Keywords: Acid Mine Drainage, Active Treatment, Passive Treatment, Coal Mining.

Abstract

This paper describes some of the general condition of the oceanographic parameters in the Strait Matak, Anambas Archipelago. The data flow is obtained by direct measurement by using a current meter types RCM-7. Simulation models using Mike 21. Mike flow pattern is divided into two seasons, namely west season (January) and the east season (August) and flow patterns ahead of the tide when the season is generally moving west to wards the south, it demonstrates the role of strong tidal influence the movement of waterin the study area. Flow velocity in the strait just before the tide on the west season reaches 1m/s.  Flow patterns at high tide on the west season looks still moving toward sthe south. The maximum flow velocity in the strait when the tide reaches 0.32 m/s, while the average speed in the area of the model is 0.12 m/s. Low tide towards the current pattern is still moving towards the south, it reinforces the notion that in addition to tidal windsare also very significant role in moving the flow, in this case that the current is moving toward the south. Flow velocity just before low tide reaches 0.85 m/s. Flow patterns at low tide shows the differences in the three previous conditions, the current in the strait to move out to the north toward the South China Sea. In condition slow tide, the tida lmore dominantly than the wind, this proved to even though the wind toward the south, the currents inthestraitis moving toward snorth along the tidal flow leading to the South China Sea. Flow velocity is quite varied location of modeling; flow velocity at low tide reaches 0.5m/s, with the average 0.15 m/s. Keywords: current and direction, wind, tide, model.

Abstract

Water is a very basic need for humans, especially for cooking and drinking. With the rapid growth of population in particular need of clean water for the community also increased in numbers. The problem is with the poor quality of raw water for drinking water, then in addition to expanding its production costs, the result is often less good. One of the problems or issues that are often found in drinking water in the world these days that is the emergence of compounds called Trihalomethanes or THMs abbreviated, as a side effect of the disinfection process with a chlorine gas or hypochlorite compounds.Currently, to removal organic pollutants, ammonia, detergents, odor and other micro pollutants in drinking water, PAM is usually used by the process of manufacturing processes using adsorbsi Powder Active Carbon Adsorption, continued with physicals processing is the process of coagulation, flocculation, sedimentation and disinfection with chlorine. With increasingly high prices of powdered activated carbon, coagulant and flocculant chemicals, then the cost of treating drinking water to be increasing. To solve the problem above, one alternative is to develop clean water treatment technologies using a combination of biofiltration and ultrafiltration process, and to produce drinking water to proceed with processing using the process of reverse osmosis. Within the combination of biofiltration, ultrafiltration and reverse osmosis processes to treat the river water can be produced the drinking water with a very good quality without the use of chemicals for coagulation-flocculation process, and operational costs are relatively low. Key words : Air siap minum, biofiltrasi, ultrafiltrasi, reverse osmosis

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 mercury 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 of mercury in wastewater depending on pollutants conditions such as concentrations of mercury in wastewater, types of mercury, mercury concentrations in treated water, land availability, flow rate of wastewater will be processed and other parameters. This paper discusses several methods of removal of mercury heavy metals in industrial wastewater such as chemical precipitation and oxidation processes, adsorption and ion exchange process. Keywords : water pollution, heavy metals, mercury, industrial wastewater, removal methods.

Abstract

Drinking water supply for public is big deals for the improvement of environmental and society health. An effort from the government to provide the drinking water supply is to provide a society based of drinking water treatment plant. Some obstacles that have come for the plant in remote areas are the difficulties of getting chemical material for the plant and the lack of energy supply. Drinking water treatment that use chemical materials has a big cost to provide the chemicals. Beside the high cost of treatment, the using of chemicals will harmful the drinking water, because it usually generates such carcinogenic materials. The biofiltration-ultrafiltration treatment is one of the best solutions to replace treatment plant that using chemicals. It has a low cost operation and is more safe than the water treatment that using chemicals. Generator-set (genset), a power generator that easy to get and operate, has uneconomical operation cost. By now, there were many studies proved that in remote areas, the using of Solar Power Plant is more economic than a genset. For those reasons, in this article is designed a solar powered 50 m3/Day drinking water treatment (biofiltration-ultrafiltration process). The result from the design is the solar power plant that can supply the treatment plant for 8 hours. Keywords: drinking water, solar power, genset, biofiltration, ultrafiltration.

Abstract

The existence of regulations to control environmental pollution has grown over time in line with changes in environmental legislation. In Indonesia since the '80s has been three times experience changes in environmental legislation. Any change in the law is always followed by changes in regulations that are below it. From time to time, the environmental pollution is getting worse and require stricter regulations and implementation. Regulations are too strict sometimes not implementable and eventually are violated because there is no way out solution that does not burden the parties. Domestic waste is the largest portion of urban waste. Its existence has made the environment of rivers, lakes and ground water polluted, due to not properly managed. Regulation of waste quality standards have been tightened over time. Waste water quality standard is the limit or polluted substance or the amount of pollutant elements are tolerable in the waste water to be discharged or released into the water source from a business or activity. The existence of environmental quality standards in Indonesia are set by regulations of environment ministers. Discharge of domestic waste quality standards number P.68 / Menlhk / Secretariat / Kum.1 / 8/2016 has brought on changes in the use of domestic wastewater treatment technologies, as happened tightening in several key parameters, which is still within the limits loose. Keywords : Environmental regulation, waste treatment technology
