Another ,source, of ocean pollution by sewage-related waste is the disposal of biosolids, a semisolid byproduct of the sewage treatment process, often called sludge. Historically, sludge in developed nations was disposed in coastal waters: New York's twenty sewage treatment plants, for example, once disposed their sludge offshore in a region known as the New York Bight.

For this study, the short chain VFAs commonly found in winery wastewater, namely acetic acid, propionic acid and butyric acid, were considered. Previous studies have reported that acetic acid, which is a ubiquitous molecule involved in the central and subsidiary bacterial metabolic pathways, constitutes the major fraction of these VFAs ( Malandra et al. 2003 ; Sheridan et al. 2011 ; Welz et al. 2014 ).

Phosphoric acid wastewater, treatment to substantially eliminate discharge of contaminants to the environment. ,Acid, pond water from conventional wet-,phosphoric acid, manufacturing is replaced by gypsum pond water having a pH closely matching that of the surroundings. Essentially all fluorides are insolubilized and substantially all ,phosphoric acid, is recovered, minimizing loss to the environment.

Chemicals used for pH Neutralization of Industrial Wastewater

Chemicals Used for pH Adjustment of Industrial Wastewater. The most commonly used neutralization chemicals for acid or base neutralization are 93% Sulfuric acid and 50% Sodium hydroxide. In many cases these are very good choices, however, there are many considerations when selecting chemicals and these may not always be the best selection.
