Treatment of produced water mixed with polymer - NASA/ADS
In the petroleum industry, polymer flooding is one of the main methods in enhanced oil recovery (EOR) that applies a water-soluble polymer such as partially hydrolyzed polyacrylamide (HPAM) to increase oil production. It is added to the flooding water to improve the oil movement. During the process, water is produced as a by-product along with oil and gas production.
A large part of produced water should be injected back into the stratum for reuse (Taylor et al., 1998), and the rest will be discharged into water bodies or surrounding soils. Produced water from Polymer Flooding (PWPF) which contains a lot of residual hydrolyzed polyacrylamide (RHPAM) is the wastewater of polymer flooding.
Treatment of wastewater produced from polymer flooding
Polymer flooding is an enhanced oil recovery process. Water-soluble polymer, for example partially hydrolyzed polyacrylamide (HPAM), is added to the flooding water to improve the mobility ratio in the flooding process. Polymer flooding plays a major role in global crude oil recovery , especially in China , .

Produced water from polymer flooding process in crude oil
Produced water from polymer flooding was much more difficult to be treated than that from water flooding in many oilfields. The simulated experimental results showed that the small initial sizes of oil droplets were the main reason that caused the difficulty in treating the produced water from the polymer flooding process.

Current research trends on plastic pollution
Many organisms, including humans, depend on the soil for their survival, and therefore, soil pollution is a critical factor, even affecting food safety for humans (Akhtar, 2015, Micó et al., 2006, Li et al., 2014a).As industrial development has accelerated and the manufacture and disposal of plastics have increased, concerns on plastic pollution are growing.

Polymer flooding can significantly improve the sweep efficiency in heterogeneous reservoirs compared to a water flood. This is caused by the improved mobility of the polymer flood, which has an effect on the crossflow mechanisms caused by viscous, capillary and gravitational forces in the reservoir.

- Sodium fluoride: a dry additive, typically used in small water systems, dissolved into a solution before being added to water. Most fluoride additives used in the United States are produced from phosphorite rock. Phosphorite is used primarily in the manufacture of phosphate fertilizer.
- How does NSF certify fluoride products?
- NSF certifies three products in the fluoridation category: How do fluoride products work?
- All three products readily break down in water to release fluoride and related ions. Fluorosilicates fully dissociate to fluoride and silicate ions in association with either hydrogen or sodium ions.
- Which additive is used for water fluoridation?
- Community water systems in the United States use one of three additives for water fluoridation. Decisions on which additive to use are based on cost of product, product-handling requirements, space availability, and equipment. Fluorosilicic acid: a water-based solution used by most water fluoridation programs in the United States.
