Commonwealth Honors College, UMass Amherst. The Hill Can Do Better to Care for Those Over the Hill. The growth of the elder population in the United States will push the already challenged eldercare network to its limit. Elderly individuals are some of the most vulnerable, relying on the support of the government and younger generations.

Polymer (coatings and laminates) corrosion involves the movement of ions, water and select formula ingredients into and through the polymer. Water tends to open up the polymer as it is absorbed and diffuse between the polymer molecules. Water also breaks polymer-metal bonds causing polymer delamination, such as blistering.
A WPI education has never been more relevant than it is today, because the demand for innovative thinkers who can solve problems on a global scale has never been greater.

- What is high-purity poly-aluminum chloride (PACL)?
- Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed.
- Is polyaluminum chloride a good coagulant for water treatment?
- Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water [ 6 ].
- What is the basicity of high-purity PACL?
- The basicity of high-purity PACl can be maintained at about 92% after the adjustment by calcium aluminate (Table 3), it has exceeded the national and international standards of PACl.
- Which polymers are used to make high-purity PACL?
- After PACl was prepared, the polymers with a sulfydryl group and modified PAM were added into the conventional liquid PACl, this not only removes iron significantly, but also accelerates the sedimentation of insoluble suspended matter. The properties of high-purity PACl synthesized by bauxite and calcium aluminate are shown in Table 3.
