A. EXPORT & IMPORT waste liquid (MIKO)
Palm oil mill waste liquid. Simple solid waste and solid waste may be disposed of to a vacant land, buried or burned in incinerators. While the liquid waste discharged into public waters (rivers). When the waste produced can damage the environment and pollute the waste was no longer discarded but processed in such a way that it is beneficial to plants around pabrik.PKS required to produce waste that 'quality'. Course demands for increased quality of generated waste processing costs. On the whole it is defined as waste management (waste management). Waste treatment has several stages namely:
character Liquid Waste
The results show that the MCC MCC quite efficiently produce 0.6 - 0, 8 m³ wastewater (LPCK) / ton FFB on though. The wastewater comes from classification station (sludge water from the drab, 70-75%), station stew (condensate water, 15-20%), from hydro silk on (5-10%) and water washing plant. characteristics or LCPKS quality parameters of each - each source of waste is different from one another. LCPKS whole unprocessed BOD usually have around 25 thousand mg / l. Because it is capable of damaging the ecological quality of waters in exile, LCPKS managed properly so that the amount / debit and decent quality to be discharged into public waters.
Some common approaches applied in the management or control LCPKS are:
• Water conservation: separation and recycling (reuse) the turbine cooling water, condensate water from the boiler, overflow / spill of vacuum dryer.
• Adjustments to the effective use of water (good in - house keeping)
• Processing LCPKS such that BOD falls below the limit set in the government (bold 2) for example to about 50 mg / l, which come with oil separation LCPKS, reduce BOD by means of chemical, physical and biological.
Water Conservation
Clarification of waste water discharged from the station into the fat-pit, while the wastewater from hydro cyclone flowed into the effluent treatment plants (UPL) aerobic or an end (final pond, because the number of BOD or COD waste is relatively low. Levels ALB wastewater derived from fat fit and TPM before and after the MCC operation, respectively from 4.0 to 8.5%, and 3.8 to 6.8%. Baskulator used to measure the waste water that comes from the cooking station and station clarification , while the gauges used for the flow of waste into the TAP appliance in us level clamp with indicator, which measures the level of the water surface is described by the scale on the meter wall of TAP. If done boiling TBS, then each boiler unit with a capacity of 10 baskets Lori will be generated 2 0.5 to 3, 0 tons of condensate water and water vapor from 0.25 to 0.50 tons. To keep the water boiling and steam condensate water is not stagnant under the kettle boiling, keep in pairs chimney exhaust (steam blow down silencers) with distance certain of the boiler, and the condensate drainage pipe so that the floor around the cooking station is always dry and clean.
Sources of Waste
Wastewater from the equalization solution used processing unit itself is the soaking water, hair removal, administration lime slurry, ammonia soaking, pickling, equalization, bleaching, giving brown color, and staining and washing of the former, droplets and spills.
Hair removal with lime and supplied is usually the main contributor to the pollution load in the plant equation. Wastes with high BOD and PTT derived from the former immersion fluids, fluids and fluid equations former lime plant. Cairn chrome tanned containing trivalent chromium-high levels. Soaking ammonia-nitrogen mixture left many a little ammonia and organic material. Of wastewater containing fur hair removal surgery and sulfide.
Control in the Factory
In the tanning operation, the following ways to save water usage:
1.use vat process with the opposite flow
2. Collection washing water for reuse in the addition of mother liquor.
3. Sistem wastewater in the plant for recycling and recycled directly after specific processing.
4. Sistem control the use of water, meter or a measure of time.
5. Rule good housekeeping.
6. Use washing with opposite flow than with prose’s flushing continuous. Use leather processing engine to replace the barrel or drum to the process unit and beam equalization process.
Another way to reduce waste include:
1. Regeneration (purification of the mother liquor) and the re-use of chrome tanning solution
2. 100% recycled vegetable tanning solution is now widely applied
3. Collection of waste from the removal of the rest of the meat for animal feed or glue-making materials
4. Save feathers for sale to the carpet factory
5. Regeneration of hair remover liquid
6. The use of new processes such as enzymes, oxidation, dim ethylamine at caustic soda for hair removal
7. The use of new chrome equalization process, which involves the dicer oxalic acids and salts as a substitute for chrome

sometimes waste streams need to be processed separately to reduce the concentration of some contaminants in the wastewater. Stream containing sulfide can be oxidized to reduce sulfide levels. Trivalent chromium is almost always because they do not need to be reduced hexavalent form. Stream containing chromium can be deposited by using alum, iron salts or polymers at high pH. Chrome may be recouped by filtering sediment, dissolving it in acid and re-use it for tanning. Another primary treatment process cover filtering, equalize and precipitation to reduce BOD and solids obtain back. Chemical processing by using alum, lime, ferrous chloride polyelectrolyte can further reduce the PTT and BOD. Biological treatment system is working effectively. Varying rates of flow and levels of possible big waste.
Therefore, the system should use tanning or high flow rate systems. Anaerobic system is effective, but it will issue a pungent odor dang disturbing residential areas. Oxidation ditch systems, an aerobic, as light drops and activated Lumpur is already widely used. Lakes (anaerobic and aerobic) constitute a cheap and effective system, if designed and operated properly and if the land is available. If necessary, a system can be used to eliminate the high levels of nitrogen. In the new operation has been used adsorption (absorption) and sieving carbon micro to reduce contaminants to a low level.
