OIL FIELD WATER TREATMENT SOLUTIONS

Water treatment and management are an integral part of oil and gas production. The complex and variable produced water quality and stringent injection water quality requirements have brought great challenges to water treatment. Huafu has developed and implemented innovative and differentiated solutions, which can help oilfields to achieve good management of produced water treatment, injection and thermal energy recovery of sewage.

Water treatment under complex and variable water quality and harsh water quality requirements
Oil field stimulation technology usually needs to inject a large amount of water into the formation, and at the same time produce a large amount of produced water. The produced water cannot meet the standards required for reinjection. Different formations have different requirements for injected water. Different formation oil displacement technologiesThe quality of produced water varies greatly, and oilfields are faced with the challenges of water treatment and water balance management.Huafu has been committed to the development and application of oilfield water treatment technology since 1998, and has a deep understanding of various complex and changeable oil and gas field produced water and fracturing flowback fluid and their water quality characteristics, such as heavy oil thermal recovery produced water, chemicalProduced water from oil flooding and high-salt produced water also meet various stringent injection water quality requirements, such as boiler makeup water for thermal recovery steam injection and reinjection water for low-permeability reservoirs. Huafu has always been a reliable partner in the oil and gas industry, and we are proud of providing reliable products and services to internationally renowned oil companies, contractors and operators.Whether it is onshore oilfields, offshore platforms or floating production storage and offloading (FPSO), whether it is conventional produced water, SAGD produced water, heavy oil produced water, chemical flooding produced water or fracturing flowback fluid, no matterWhether it is reused as supplementary water for steam injection boilers, chemical oil flooding with polywater, low-permeability reservoir reinjection water or fracturing fluid water, our professional technical team can find ideal processes, technologies and products to meet your needs.All specific project needs.

Technology Solutions

Flotation

Dissolved Air Flotation (DAF) is a proven and highly effective physical/chemical technique for treating a variety of industrial and municipal processes and wastewater streams.DAF systems are commonly used to remove grease and suspended solids to meet a variety of treatment objectives, including: ● Pretreatment to reduce the impact of oil on downstream filter treatment systems ● Pretreatment to reduce load on downstream biological treatment systems ● Polishing of biological treatment effluent ● Product Recovery and Reuse ● Concentration of Biosolids ● Pretreatment to meet sewer discharge limits

Oil Water Separator

The basic principle of difference in gravity between the phases is employed in an OWS in separation of the two phases.Adding inclined plate group in the OWS separation area, basedon the principle of laminar flow, can significantly improve the efficiency of oil-water separation.

Filtration

Granular media filtration is the key equipment or facility of particulate removal for water treatment plants. Huafu’s granular media filters include walnut shell filters, multi-media filters and ultra-fine filter materials. Skid-type filters include tanks, water inlet distribution pipes, Bottom water collection pipes, backwash air distribution/water distribution pipes, pipelines, instruments and control systems.

Automatic polymer dosing

HFJY-II automatic dosing device is another new type of automatic dosing device developed by the company on the basis of years of water treatment project practice, which can ensure sufficient ripening time, and the dosing device realizes continuous preparation and dosing from dry powder to set concentration of chemical solution

Resin softeners

Ion exchange refers to the water treatment method in which the ion exchange agent is used to make the exchangeable ions in the exchange agent and the water solution undergo reversible exchange with the same mass rules, while the structure of the ion exchange agent does not change substantially. Ion exchange technology is widely used in the field of water treatment. Such as water softening, water desalting, high-purity water preparation, industrial wastewater treatment, heavy metal and precious metal recovery, etc.

Ultrafiltration membrane filtration

Featuring low suspended solids in outlet water and bacteria and viruses removal, ultrafiltration membrane separation technology greatly improves the quality of reclaimed water, and is also an ideal pretreatment technology for reverse osmosis. With the progress of ultrafiltration membrane technology and the reduction of cost, ultrafiltration membrane will be the first choice for the recycling of reclaimed water. Thanks to long-term engineering practices and experience, we have successfully overcome the problem of membrane pollution in wastewater treatment by optimizing the membrane operation and chemical washingtechnologies, and achieved long-term stable operation of ultrafiltration membrane units. The ultrafiltration membrane units developed by us include hollow fiber ultrafiltration membrane unit, tubular membrane ultrafiltration unit and ceramic membrane ultrafiltration unit. We can provide an overall system design scheme according to customer needs, and customize packaged ultrafiltration membrane unit.
