Produced water treatment device
———
Technical introduction
———
———
Based on the characteristics of different solubility of gas in water under different pressuresa high-pressure gas dissolution system is used to pressurize a part of backwater and gas to formgas dissolved water, produce micron bubbles that are released inside the tank.
The device integrates six core technologies and has eight product advantages, including fastdemulsifcation,efhcient oil removal, and suspended solid removal.
Technical Advantages
———
———
It is fully enclosed and can solve VOC problems
It utilizes front-end pressure, with short process
It can recycle gas, save energy and cost
It has no vulnerable parts, no fllers, and has easy maintenance
It has effcient processing with small land use
Under pressure, sludge discharge and oil collectionare convenient
It has strong resistance to impact load
It has hiah level of self-control, and is unmanned
Application Scenarios
———
———
The device has a short process and is skid-mounted, which can shorten construction period, achieve fast revenue, and is suitable for various development stages of new and old oil areas.
A certain produced water treatment station in Shengli Oilfield was put into operation in October 2024, with one Super-cavitation airtight flotation equipment( skid-type) and a treatment capacity of 2000m'/d. Outlet oil concent <30mg/L, suspended solid concent <15mg/L, improves the water quality.

Technical introduction
———
———
Efhcient dissolved gas and supercavitation facilities are added in the tank, and the airflotation is organically combined with the large tank, which has the advantages of efhcient oilremoval of air fotation and impact resistance of large tank, thereby improving oil-waterseparation efhciency and enhancing the processing capacity of the large tank.
Technical Advantages

Closed, as circulationSave energy and reduce consumption, solve VOC problems.
Reduce cost and increase efciency
Reduce drug dosage
ncrease crude oilrecovery
Improve effciency
Improve demulsifcation effect
2-3 times increase in processing power
Save investment
Reuse existing large tanks
Reduce hxed assets investment
Application Scenarios
———
———
The construction of large-scale produced water treatment stations or the renovation ofexisting tanks have been applied in multiple heavy oil and polymer-contained produced waterstations in Shengli Oilfeld, with a treatment capacity of 4.5x10'm'/d. Compared with regulartreatment processes, it can achieve efhcient oil-water separation, solve VOC problemsreduce investment by more than 40%, and reduce the operating cost by more than 20%.
● A certain produced water treatment station in Shengli Oilfield was put into operation inJanuary2023, with two 5,000m'Super-cavitation airtight flotation equipment( tank) and a treatmentcapacity of 4.3x1 0'm' /d. lt improves the water quality, reduces treatment costs, and achieves closedandenvironmentaloperation.
● The clean hot water station in Shengli Oilfield was put into operation in January 2022, withone200m’Super-cavitation airtight flotation equipment( tank)and a treatment capacity ot2,000m*/d. Outlet oil content<20mg/L, suspended solid content <15mg/L, which stably meets the
standard.
