Objective

Produced waters are a mixture of formation water and water injected in reservoir pressure maintenance system separated from the well production in the process of their conditioning, and water which is injected in reservoir pressure maintenance system.

Three common challenges often occur during treatment of produced water:

• Low efficiency of existing bottom settlement and produced water treatment technologies (concentration of petroleum products after treatment is 60-70 mg/l against required 50 mg/l max.)

• High CAPEX and OPEX incurred in terms of existing treatment technologies.

• Negative impact of Oil ad Gas Complex industries on environment.

Wastewater treatment option with flotation plant

The oil-contaminated wastewaters are treated with activator and Biomicrogels® BMG-C2 flocculator. The water treated with agents is then supplied through static mixer for better mixing and distribution of the flocculator through the wastewater volume. After that, the wastewater is supplied to flotation plant where pollutants are removed as flotation froth owing to physical and chemical treatment method.

Wastewater treatment option with drain sump

The oil-contaminated wastewaters are mixed with activator and agent in static mixer and supplied to the drain sump thereafter.

After settlement of the source emulsion the treated water is supplied to separate tank, and remaining settlement is supplied to water abstraction.

Owing to these agents, the concentration of petroleum products is reduced to 0.05-1 mg/l, the costs of measuring the agents are decreased by means of improvement of agents’ proportions and increasing the agent response rate. The volume of IV hazard category sediment handed over to dumping or disposal is also decreased.

Biomicrogel® BMG-P2 catch any mineral and vegetable oils, animal fats, and oil and petroleum products in water effectively, based on sweep- coagulation process.

They catch any mineral and vegetable oils, animal fats, and oil and petroleum products in water effectively, based on sweep- coagulation process. 

After separation of oil-water mixture both treated water and removed petroleum products can be returned to the process cycle and re-used. Biomicrogel® BMG-P2 flocculants are well compatible with almost all flocculants based on inorganic salts of polyvalent metals cleaning water from suspended particles.

Biomicrogel® BMG-P2 flocculants must be diluted in water using static mixer or other appropriate mixing device suitable for making homogeneous solution.

Biomicrogel® BMG-P2 flocculants are supplied as powder. They are packed in 25 kg polypropylene bags, and the bags are then placed on pallets. Pallet houses 20 bags – 500 kg of the flocculant.

Biomicrogel® BMG-P2 flocculants as solution are supplied in 1000 liters IBC containers.

Biomicrogel® BMG-P2 flocculants as paste are supplied in 19 kg plastic buckets or in 220-liter barrels as requested by customer.

Store the product in cool and dry place. Keep the entire protective packaging safe before using the product.

Guaranteed storage life in dry form – 24 months as of date of manufacture. To avoid hydrolysis or increase of microbial counts, fungi, hence resulting in deterioration, use the treatment solution within 14 days, if prepared on your own.

After precipitation from water Biomicrogel® BMG-P2 flocculant shall be disposed of in accordance with effective legislation.
