Introduction to Flopam AN 905 VHM
Flopam AN 905 VHM is a form of anionic polyacrylamide (APAM), characterized by its high molecular weight and negative charge. While direct application data for this exact grade is limited, we can infer its uses from industry-standard roles of APAM and similar SNF Flopam variants. APAM broadly serves as a flocculant, enhancing solid–liquid separation through charge neutralization and bridging.
1. Industrial and Municipal Wastewater Treatment
APAM—including Flopam AN 905 VHM—is widely used for treating wastewater across municipal and industrial settings:
-
It effectively flocculates suspended particles in neutral to alkaline sewage, promoting rapid sedimentation and filtration. This greatly enhances clarity and treatment efficiency.asiafloc.comasiafloc.com
-
Industries such as chemical processing, metallurgy, coal washing, mineral processing, iron and steel, textiles, electronics, and paper and pulp all utilize APAM for solid–liquid separation and effluent polishing.asiafloc.com+1chinafloc.com
-
In municipal and high-turbidity water treatment, APAM often complements inorganic coagulants, achieving better results at much lower dosages.asiafloc.com
2. Sludge Thickening and Dewatering
Flopam AN 905 VHM is likely utilized to optimize sludge processing in treatment plants:
-
In sludge thickening, it promotes the aggregation of fine particles to increase solids concentration.
-
For dewatering, APAM facilitates water separation from sludge via floc formation, improving performance in belt presses, filter presses, centrifuges, etc.—resulting in drier, more easily managed sludge cakes.asiafloc.comtegetkimya.com
This significantly reduces operational costs and environmental impact.
3. Mineral Processing & Tailings Management
In mining, Flopam AN 905 VHM serves several critical functions:
-
It acts as a flocculant in mineral processing, aiding in the separation of valuable minerals from waste through sedimentation, flotation, and filtration.chinafloc.comasiafloc.comchinafloc.com
-
In tailings management, it supports sludge consolidation and dewatering—helping to minimize tailings volume and enhance storage stability.chinafloc.comchinafloc.com
4. Oil & Gas Industry
APAM products like Flopam AN 905 VHM play several roles in oilfield operations:
-
Enhanced Oil Recovery (EOR): By increasing the viscosity of injected water, APAM improves sweep efficiency in reservoirs. It's injected to reduce oil–water mobility ratio and boost extraction yields.chinafloc.comWikipedia
-
Drilling Fluids: It functions as a viscosifier, maintaining mud stability and facilitating efficient cuttings removal.chinafloc.com
-
Fracturing Fluids: APAM produces high-viscosity fluids that aid in prop-pant transport during hydraulic fracturing.chinafloc.com
5. Papermaking
Flopam AN 905 VHM is useful in multiple papermaking roles:
-
As a retention and drainage aid, it improves retention of fibers and fillers, increases paper strength, and enhances even sheet formation.chinafloc.comchinafloc.com
-
In sizing, APAM improves water resistance, printability, and durability of paper products.chinafloc.com
These benefits reduce material loss and elevate final product quality.
6. Color and Phosphorus Removal
Environmental treatment applications include:
-
Phosphorus Removal: APAM helps form flocs with phosphorus-bearing compounds, facilitating removal from water bodies and curbing eutrophication.asiafloc.com
-
Color Removal in Industrial Effluents: Especially effective in textile, pulp, and paper industries, APAM aggregates dye molecules, aiding in color removal and compliance with discharge regulations.asiafloc.comasiafloc.com
7. Construction & Soil Stabilization
APAM finds application in geotechnical and construction contexts:
-
In concrete admixtures, it enhances dispersion of cement particles, reducing water demand and improving concrete strength.asiafloc.com
-
As a soil stabilizer, APAM improves soil structure, reduces erosion, and increases load-bearing capacity, ideal for roads, embankments, and geotechnical reinforcement.asiafloc.com
8. Personal Care & Cosmetics
Interestingly, APAM also features in personal care:
-
Used in hair care (shampoos, conditioners, styling gels), APAM adds manageability, softness, shine, and frizz control.asiafloc.com
-
In skin care (creams, lotions), it acts as a film-former, enhancing moisturization and silky texture.asiafloc.com
9. Additional Industrial Uses
APAM's versatility extends further:
-
Chemical & Emulsion Polymerization: It stabilizes emulsions, preventing phase separation during polymer synthesis.asiafloc.com
-
Industrial Cleaning: It boosts cleaning agents by aiding removal of grease and dirt—used in detergents and degreasers.asiafloc.com
10. General Context – Polyacrylamide Usage
According to broader sources, polyacrylamide variants—including anionic types—are heavily used in:
-
Flocculation processes across water treatment, papermaking, and screen printing.Wikipedia
-
Soil conditioning, by improving aeration, reducing compaction, and aiding water retention—though this use is typically limited due to cost.Wikipedia
APAM also supports potable water treatment by bridging inorganic salts to enhance organic removal.Wikipedia
