Using Polyacrylamide (PAM) to Reduce Erosion on Construction Sites | NC State Extension Publications
At $6 per pound, this is an additional $120 per acre, which is a small fraction (less than 5 percent) of the usual hydromulching operation costs. The additional time for mixing will also need to be considered, however. Do not apply PAM to

The fabrication of a cationic polyacrylamide (CPAM) with high efficiency and economy has been highly desired in the field of high-turbidity water treatment. This study introduced an ultrasound (US)-initiated template polymerization (UTP) method
Introduction Cationic polyacrylamide (c-PAM) has been widely used in sludge dewatering in municipal sewage treatment plants because of its characteristics, which include low dosage, high efficiency, and pollution- Corresponding author: Jiawei
Processes | Free Full-Text | Synthesis of the Hydrophobic Cationic Polyacrylamide (PADD) Initiated by Ultrasonic and its Flocculation
In this study, a new type of hydrophobic cationic polyacrylamide P (AM-DMC-DABC) (PADD) was synthesized by ultrasonic (US)-initiated polymerization, which is used for the separation and removal of coal mine wastewater. The acrylamide (AM),
This work examines the addition of cationic polymers, cationic polyacrylamide (CPAM) and polyamide–amine–epichlorohydrin (PAE), to cellulose nanofibres to produce superior forming characteristics. The addition of 2 mg of high MW CPAM/g of
One-Step Preparation of Antifouling Polysulfone Ultrafiltration Membranes via Modification by a Cationic Polyelectrolyte Based on Polyacrylamide
A novel method for one-step preparation of antifouling ultrafiltration membranes via a non-solvent induced phase separation (NIPS) technique is proposed. It involves using aqueous 0.05–0.3 wt.% solutions of cationic polyelectrolyte based on a

- What is the technology of PHPA mud systems?
- Although more is known from field applications about how practices, although more is known from field applications about how the products work and the systems behave, the technology of PHPA mud systems is still developing. Drilling of oil and gas wells always results in the incorporation of native clays into the mud system.
- Can PHPA mud be used offshore?
- In North Sea applications, PHPA muds are being used offshore The Netherlands successfully and routinely. However, poor results were obtained in offshore Norway and U.K. applications because of formation reactions, inadequate mixing and solids-control equipment, and general inexperience with water-based muds.
- Does PHPA reduce mud viscosity?
- The addition of 1.0 lbm/bbl [2.9 kg/m3] PHP A reduced the free water to the point that the mud viscosity was excessive. This same mud operating at 15.3lbm/gal [1830 kg/m3] exhibited a normal viscosity. In retrospect, PHPA should have been added in stages and allowed to circulate several times between each stage to avoid these excessive viscosities.
- How has PHPA mud changed the drilling process?
- In wells drilled with PHPA mud, the number of bits was reduced from seven to two, rotating hours were reduced from 128 to 58, drilling progress was increased from 254 to 499 ftlD [77 to 152 mId], and total days were reduced from 12 to 6.
