Flocculant

Techdirects' flocculant powders include cationic flocculant (polyacrylamide, PAM), anionic flocculant (polyacrylamide, PAM) and nonionic polyacrylamide (polyacrylamide, PAM), used for water treatment; oilfield, mineral processing, paper making and other application areas.

Cationic flocculants
Techdirects' cationic powders range from low to very high molecular weight, low charge to very high charge. Sludge press, centrifuge whatever your dewatering requirements our premium cationic powders are rugged and economical enough to get the job done.
Anionic flocculants
TechDirect's anionic powders range from low to very high molecular weight, low charge to very high charge and are a premium product suitable for all types of industrial treatment regardless of your industry.
Non-ionic flocculants
TechDirect's non-ionic powder is low hydrolysis degree medium molecular weight, used for　mineral processing and water treatment.

Applications

Displacement agent for tertiary recovery of oilfield
It can adjust the rheology of water injection, increase the viscosity of the displacing liquid, improve the spreading efficiency of liquid displacement, bring down the water permeability in strata and keep the water and the oil to flow at a constant speed. It is mainly used in the tertiary recovery of the oilfields. Injection of each ton of PAM products can help to gather 100-150 tons extra crude oil.

Drilling mud material - (PHPA - Partially Hydrolyzed Polyacrylamide) 
PHPA Anionic polyacrylamide is used as oil drilling mud additive.  Used as drilling mud additives in the oilfield exploration and development and geology, water conservancy and coal exploration. It can prolong the bit's life, raise the drilling rate and the drilling footage, and reduce the time of drills exchange. It has obvious effect in avoiding well collapse. It can also be used as the oilfield fracturing fluid and the profiling water blocking agent.

Industrial wastewater treatment
Especially for the treatment of wastewater containing suspending particles, which is coarse, highly concentrating, with positive charges, and under neutral water PH value or alkaline. Most effective for wastewater treatment of iron and steel plant, electroplate factory, metallurgy and coal washing etc.

Drinking water treatment
Many water sources such as river water contains large sum of sediment and mineral, very turbid, even after precipitation and filtration it still cannot meet the requirements, therefore  flocculants are needed. The water plants used to use the inorganic flocculants, but large amount of additives is required which cause the increase of sludge volume and is not effective. By using the anionic PAM flocculants, with 1/50 additive amount that of inorganic flocculants, it will achieve several times and even dozens of times of the effectiveness than that of the inorganic flocculants. For those organic polluted river water, better effectiveness can be achieved while using together with cationic PAM.

Papermaking additives
It can be used for the caustic soda's clarification, used as the retention aid, the filter aid, and the reinforcing agent for wet and dry paper.
