Aluminum sulfate regeneration from surface water treatment

Aluminum sulfate is used for surface water treatment, which leads to waste sludge being disposed into water bodies, causing environmental pollution. Coagulants' regeneration from sludge improves water quality and reuse options. Organics accumulation is the primary concern regarding coagulant regeneration, using acidification.

NPDES: Stormwater Best Management Practice, Alum Injection

While the most common use of alum is as an in-line treatment of stormwater, another use is as an in situ treatment of surface waters such as lakes (Welch and Cooke, 1999; Harper, 2007), reservoirs and combined sewer overflow storage areas.

Alum (aluminum sulfate) turns polluted lakes from green to

Introduction. Surface waters with elevated (above background) aluminum concentrations from natural and manmade processes can create toxic conditions for aquatic life, such as invertebrates, amphibians, and fish; for example, aluminum accumulation on fish receptor sites (gills and olfactory glands) impairs metabolic and respiratory functions and can be lethal (Rosseland and others, 1990; Exley
