palm oil factory waste water treatment station

In the palm oil processing can produce the waster water contain the COD and BOD. It must be treated before discharging, the waster water is setting for this purpose.

The waster oil produced in the processing not only contain the oil, but also contain the COD and BOD, it is the high concentrated organic wastewater, so it has to be treated before discharging out of the factory. The harmful matter content in the waste water as follows:

COD                       5000mg/l

BOD                       15000mg/l

Suspended solid      7000mg/l

Plant Oils                 300mg/l

PH                            4~5

Temperature            80~90℃

Wastewater quantity

According to calculation, this project can produce about 250 ton waster water per day.

Emission standard

Water after handling reach the “integrated wastewater discharge standard” standard:

COD              120mg/l                         Oil               20mg/l

BOD               30mg/l                          SS                30mg/l

pH                  6-9

The waster water discharging from the palm oil factory is the high concentration organic wastewater. This kind organic wastewater handling use the combination method of chemical method and biological method. First adopt the coagulation method remove the large number suspended solids and other impurities, then use the biological method remove the organics in the water. Chemical method we adopt the gas flotation method, biological method we adopt the anaerobic aerobic biological packing method to process. Anaerobic tower mainly used in acid hydrolysis stage, make the anaerobic bacteria and anaerobic bacteria broken down the complex degradation-resistant  organics into simpler organisms, then adopt the contact oxidation method remove the organics in the water. Contact oxidation method utilize the microorganism on the packing film contact with the organics and Dissolved Oxygen in the wastewater. Make the organics decomposition, so purify the wastewater. Not only the bio-film on the packing react, but also the slurry microorganism react, so the biological contact oxidation treatment effect is better than the general biological membrane method.Biological packed tower using ceramsite as filler, can remove the Residual pollutants further, mainly remove the COD, BOD, chromaticity and other organic matter.

This process craft is tertiary treatment, after primary air-flotation treatment, the COD can reduce about 80%, and BOD reduce about 60%. After secondary anaerobic digestion and contact oxidation, both the COD and BOD can reduce 80%-90%, after tertiary treatment biological packed tower, all the indexes can meet the national effluent discharge standard.

Power engineering design

Fuel supply

Fuel mainly in the production process use by-product – fiber, waste recycling, at the same time also meet production requirements.

Water supply

After the completion of the project, the daily water need is about 1387 tons, the main using in the boiler workshop and palm oil workshop, water supply is the river near the river, after water treatment system, make it meet the production requirements.The factory also has a water reservoir, so that when water supply disruption or insufficient to ensure normal production and fire needs.

Power supply

This project adopts the boiler steam power generation, power generating capacity is 630 kva, to meet the requirements of production and life.

Heating supply

Using the boiler steam to power generation, power plant steam for production, waste heat utilization.

According to customer different needs, we also can help you to extend the project, striving to help you develop a vast market and profitable business opportunity.If you want to start your own palm oil factory business, please email to [email protected]
