    Enhanced algae removal by drinking water treatment

    According to the actual situation, in the algae outbreak period, conventional technology is enhanced to remove algae by increasing dosage of coagulant and chlorine, with the dosage of potassium permanganate 0.3 mg L −1, obtaining high algae removal efficiency. The higher the algae density, the more the algae removed.

    Conversely, although UV pre-oxidation had a less effect than the Al coagulant on algae removal rates, it enhanced the removal rate to different degrees compared without UV irradiation. For example, a maximum removal rate of 90% was achieved after 240 s of UV irradiation (0.4 mmol/L Al), whereas the maximum removal rate without UV irradiation

    Algal control and enhanced removal in drinking waters

    Previous studies have recommended the use 0.5–3 mg/L permanganate for enhanced algal removal by alum coagulation (Chen & Yeh 2005; Heng et al. 2008). Heng et al. (2008) indicated that a 0.5 mg/L permanganate dose in combination with chlorine achieved the best reduction efficiencies in turbidity and chemical oxygen demand Mn in raw surface waters.

    Removing algae, both mechanically and biologically | Velda

    Removing algae. Nothing is more bothersome than an excess of algae in a pond. You want to remove them. A pond is an unbroken ecosystem. Biological wastes are converted by bacteria into nutrients for water plants, which in turn give off oxygen to water, thus providing a healthy pond environment.
