Flow-back Water Treatment Device

Flow-back Water Treatment Device is a self-developed Flow-back Water treated for re-use and re-injection device by our company based on years of experience in oil and gas field Flow-back Water treatment and comprehensive utilization production.The device integrates automatic dosing, multi-reaction, oil-water separation, solid-liquid separation, fine treatment, sludge concentration and dehydration and other process units.It has small footprint, short installation and debugging cycle, high automation and easy operation. And It can adapt to different fracturing systems and different fracturing processes to form different waste liquid to meet the standard requirements, to ensure that the output water quality meets the requirements of re-injection or replenishment.

In addition, we can provide oilfield flow-back water treatment or flow-back water treatment technology services according to clients needs.

Product Type:

Skid:It is suitable for centralized station construction, dealing with long-term, large-scale flowback treatment on well site.

Technical Characteristics:

a).Wide application range, strong impact resistance, it can handle different kinds of flowback water formed by different fracturing systems and different fracturing processes to ensure that the output water quality meets the requirements of re-injection or reuse;

b).We modified the traditional medicinal agent, developed a Haimo  flocculation system, greatly shortened the flocculation reaction time, and achieved rapid flocculation and sedimentation within 3 minutes;  

c).The process is flexible, and it not only can be used to a station to treat a large number of flowback water in a regional well site, but also used to a mobile device to treat short-term flowback water;  

d).It can meet different processing standards and requirements, and can be used to reuse for fracturing fluid process and reuse for injecting water; 

e).The device is skid-mounted , which can be used in station and can also be moved by vehicle; 

f).Device is assembled and debugged in the factory, which is convenient for quick installation and commissioning on site.

The technology and supporting devices are widely used in domestic oilfields such as Changqing Oilfield of CNPC and Yanchang Oilfield to meet the different processing requirements of the owners.
