Abstract

Center Steam Power (power plant) is a system of several generating units that rely on mechanical energy from the steam to generate electricity. One type of waste generated by the activities of Steam Power (power plant) is a liquid waste. Power Plant is one of the Thermal Power Plant which contributes removable waste water into the surrounding environment. Waste water originating from a variety of operational activities in the area of ​​the power plant when released into the environment without prior treatment can harm organisms that live around and through the food chain can also be harmful to human health because it generally contains a substance or substances that are potentially harmful. Based on this, the facility power plant waste water treatment system is a very important part of the system of Thermal Power Plant. This research was conducted at the facility Wastewater Treatment System / Waste Water Treatment Plant (WWTP) Muara Karang power plant. The research aims to study the WWTP plant process including the technology and materials used in processing and also compare the data output / results of initial processed WWTP design (2003) with the actual (2011). The results are expected to be used to determine the extent of conformity between the levels of contaminants are released into the environment with the quality standards recommended by the Government. The method used in this research is the field surveys and interviews, as well as data analysis by descriptive analytic. The results showed that the output of the WWTP plant Muara Karang meet quality standards, ie BOD5 3 mg / l, Chromium total 0 mg / l, Copper 0.05 mg / l, Iron 0.16 mg / l, Zinc 0.16 mg / l , pH 7.32, Oils and Fats 0.668 mg / l. Efficiency of processed products for the Iron is 87.2%, Zinc 46.67%, 21.41% Oils and Fats. Based on these data it can be seen that the process of wastewater treatment systems Muara Karang power plant includes five stages, namely the pretreatment, primary treatment, secondary treatment, tertiary treatment and sludge treatment. The performance of several components of the WWTP is less efficient due to have a lot of damage. Quality of output / processed WWTP Muara Karang power plant still operates properly, meet the quality standard of waste water issued by the government and safe for discharge into water bodies / sea.

Abstract

Condensate water is the main ingredient in the process of generating steam in the power plant condensate water uap. Therefore must have a good quality so it does not cause damage to the equipment - equipment such as pipes, tubes, valves and others. To produce water quality condensate desirable it is necessary chemicals include phosphate, ammonia and chemical hydrasin. Material is injected into some equipment such as deaerator, steam drums and others. On this occasion the discussion is about the injection of chemicals phospat. Material the chemicals injected into the water condensate (feed water) which will be precisely in the boiler to the steam injection process takes drum. For pump chemicals from the tank in order to get to the steam drum. Therefore the pump and the output pipe leading the steam drum to be reliable so it does not interfere with the injection process resulting in the boiler water quality does not match the prescribed standards that disrupts the production of listrik.Namun on the way there has been a disruption especially at pipe outlet (discharge line) to the steam drum is clogged (plugging) .This occurs because after the injection process there are still remaining - the rest of phosphate in the pump, pipe valve outlet and then dries and crystallizes as kapur.This happens especially when the power is turned off for a long time (over houl). From the above problems it is necessary to add the channel for flushing (flushing) on ​​the pump and the discharge channel leading to the steam drum, especially when the power will be off for a long time so there is no plugging in the pipe leading to the pump outlet steam line drum. The addition of the plumbing connected condensate (from discharge CEP) to the pump inlet pipe phosphate.
