Abstract

Generally, wastewater of nata de coco industry contains suspended solids and COD were high, ranging from 90,000 mg / l. The high level of of the wastewater pollutants, resulting in nata de coco industry can not be directly disposed of its wastewater into the environment agency. Appropriate technology required in order to process the waste water so that the treated water can meet the environmental quality standards that are allowed. Designing the waste water treatment plant that is suitable and efficient for treating industrial wastewater nata de coco is the activated sludge process. Wastewater treatment using activated sludge process of conventional (standard) generally consists of initial sedimentation, aeration and final sedimentation.Keywords : Activated Sludge, Design, IPAL

Abstract

In the affluent countries, the main motivations for waste reduction are frequently related to the high cost and scarcity of sites for landfills, and the environmental degradation caused by toxic materials in the deposited wastes. The same considerations apply to large metropolitan areas in developing countries that are surrounded by other populous jurisdictions. The places that currently do not have significant disposal pressures can still benefit from encouraging waste reduction. Their solid waste departments (Dinas Kebersihan), already overburdened, cannot afford to spend more money and effort on the greater quantities of wastes that will inevitably be produced as consumption levels rise and urban wastes change.Solid waste managers in developing countries tend to pay little attention to the topic of reducing non-organic wastes because the wastes they collect are between 50% to 90% organics, dirt and ashes. These municipal wastes, however, are amenable to composting or digestion, provided they contain very low levels of synthetic materials (see the Composting part of the Sound Practices section). Solid waste departments thus have an interest in promoting diversion of synthetic recyclables from the waste stream.

Abstract

In general, the main problem of domestic wastewater treatment plant (WWTP) for office buildings in Jakarta is the incompatibility between the surface load of wastewater and the capacity of WWTP. At the beginning a capacity of WWTP is already predetermined and corresponding to the rate of wastewater generated. But because of the demands of the means for the benefit of various business, so that the capacities of the office building should be developed. This case occurred on PT. Usaha Gedung BDN. Four environmental parameters, namely TSS, Ammonia, Grease Oil and COD, produced from the WWTP still exceeded the allowable quality standards. Therefore PT. Usaha Gedung BDN immediately needs WWTP capacity development plan which is adequate. Various types of technology have been widely available and ready to be used to overcome the problems of the WWTP. But on this occasion it is advisable to develop the existing WWTP facilities by adding a new WWTP unit. The first WWTP is functioned as the preliminary processing unit and the new WWTP will become an advanced processing unit. The use of a combination of anaerobic-aerobic biofilter will be relied upon to reduce pollutants that can qualify water quality standards in accordance with applicable regulations.keywords : problem identification, domestic wwtp, advanced processing
