Starch makes a comeback - 2025 - Wiley Analytical Science
So now a team of scientists from Ghana and the US, led by Francis Djankpa at the University of Cape Coast in Ghana, is exploring at the possibility of bringing starch back to the laboratory. Starch was used as a gel material in the early days of

Activated starch as an alternative to polyacrylamide-based polymers for in-line filtration of low turbidity source water
An anionic high molecular weight polyacrylamide formed 1.5-fold larger aggregates compared with the starch-based polymer tested, but both polymers produced flocs of similar density (relative
The 10ppm concentration of polymer SAM-S-II (Starch Grafted Polyacrylamide Scale up-II) has been fixed while varying the alum concentrations from 50ppm to 2250ppm. It is observed that as the alum concentration increases, the turbidity of the

A powdered silica was added to a solution of Superfloc A-130 (Cytec, Stamford, CT, USA, presently part of Solvay) (APAM), an anionic polyacrylamide of moderate charge density and a viscosity
US20080214413A1 - Water-Based Polymer Drilling Fluid and Method of Use
A water-based drilling fluid comprises a polymer which is a non-ionic polymer or an anionic polymer. The polymer can be a polyacrylamide. The fluid is used for drilling subterranean formations containing heavy crude oil and bitumen-rich oil
Both the starch and the cationic polyelectrolyte must be added prior to addition of the anionic polyacrylamide. The starch component of the treatment combination of the present invention may be dent corn, waxy maize, or potato-based and either

- Can advanced water treatment systems provide drinking water in South Korea?
- The present study investigates the feasibility of installing two different advanced water treatment systems in South Korea’s Guem River Basin for the purpose of providing drinking water (Cheongiu). The two treatments are granular activated carbon (GAC) and ozone plus GAC treatment.
- How big is the South Korea water treatment market?
- The South Korea water treatment market size was estimated at US$ 5.66 billion in 2025 and is expected to grow at a compound annual growth rate (CAGR) of 6.3% from 2025 to 2026.
- How much does a water treatment system cost in South Korea?
- The lower bound of the median WTP (willingness to pay) for installing a new advanced water treatment system is approximately $ 2 US/month, similar to the average expenditures for bottled water per household in South Korea. These lower bounds were found using bootstrapping and simulations.
- How are the benefits of advanced water treatment systems estimated?
- Benefits are estimated using choice experiments (CE) and a comprehensive cost-benefit analysis (CBA) is used to test the feasibility of installing the two advanced water treatment systems under various scenarios. The choice experiment setting uses latent class models and accounts for attribute non-attendance.
