Treatment of cutting tool lubricants in metallurgical and tube roll engineering

Description Reagents and equipment Implemented projects Other solutions

The cutting tool lubricants (cutting coolants) are steady state, kinetically stable emulsions used in intensive cutting, squirting, rolling, die forging, drilling processes et al.

The spent cutting emulsion is a consumable to be replaced.

Due to high stability of spent cutting coolant emulsions, their discharge to general purpose treatment facilities of the companies deteriorates wastewater treatment since highly emulsified petroleum products are not captured by settlement ponds and are passed through effluent filters.

In fact, the cutting tool lubricants are not decomposed naturally, therefore their discharge to ponds and treatment facilities preliminary mitigation is not permissible.

Indicator	Spent cutting coolant	Similar cutting coolant treatment methods	After implementation of solution
Petroleum products	1000-5000 mg/l	100-200 mg/l	0.05 - 10 mg/l
pH	4.0-9.0	6.5-8.5	6.5 – 8.5

Example of cutting tool lubricants separation process

pH adjustment takes place on the first stage of treatment. After that, solution of Biomicrogel® BMG-P202 flocculant and activator are added to the emulsion alternatively. After that the emulsion treated by agents is mixed in the static mixer and pipe flocculator. Thereafter the emulsion treated by agents gets to the settlement tank where the process of separation, surfacing and compaction of capsulated petroleum products takes place.

Sample diagram for water-oil emulsion separation

The water-oil emulsion with adjusted pH is supplied to collector where it is mixed with the agent and activator. The capsulated petroleum products surface during this reaction.

After that the mixture moves to the separator where it is separated into purified water, dewatered sludge or centrate and petroleum products to be supplied to further refinery.

How it works Preparation Transportation and Storage Disposal Documents

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.
