National Management Measures to Control Nonpoint Source
Activities to Control NPS Pollution Historical Perspective During the first 15 years of the national program to abate and control water pollution (1972- 1987), EPA and the states focused most of their water pollution control activities on traditional point sources, which are stationary locations or fixed facilities from which pollutants are
A. Wayne Cooley and Joe Brummer Grassland has influenced human history since prehistoric times. Grazing lands were important to prehistoric people since many of the animals they hunted for food de-pended on available forage. With time, humans began to manage grasses for increased productivity for both hay and grazing. In Great Britain, hay mak-

- Are poly-Aluminium chloride and aluminium sulphate effective coagulant agents?
- The efficiency of poly-aluminium chloride (PACl) and of aluminium sulphate (alum), two commonly applied coagulant agents, was studied comparatively in this work, during full-scale experiments in a drinking water treatment plant.
- Can alum be used as an alternative coagulant at mjwtw?
- This study investigated the use of an alternative coagulant to the traditional use of alum at MJWTW. The effectiveness of five coagulants, namely Anhydrous Poly Aluminium Chloride (APAC), Poly Aluminium Chloride (PAC), Primco 100, Zetafloc 4030 and alum (control) was investigated by flocculation tests in a laboratory using Lake Chivero water.
- What is the difference between Alum and polyaluminium coagulants?
- For water treatment applications, instead of Alum, now there are several alternative aluminium-based coagulants. Polyaluminium coagulants (PACl) consume considerably less alkalinity than Alum. Compared to Alum, PACl works effectively over a broader pH range (5.0 to 8.0).
- Which coagulant is better alum or PACL?
- (b) the direct filtration process, i.e., coagulation‐flocculation and sand filtration, but without the intermediate sedimentation step. PACl proved to be a more efficient coagulant than alum, as lower dosages of PACl, about 1.35 mg Al/L in this case, resulted to the production of treated water with low turbidity and residual aluminium content.
