Desalination and Water Treatment Algae and cyanotoxins
Moreover, Zhang et al. [10] introduced a new technology for effective removal of algae cells from the source water in water treatment based on sonication-coagulation method.
Photosynthetic algae (assimilation of CO 2, N and P) can be used in water treatment which supposes the pre-treatment of water to eliminate suspended matter and degradeable carbon and consequently encourage a good diffusion of light radiation which is necessary for photosynthesis.
Algae and Cyanotoxins Removal by Coagulation/flocculation
A continuing worldwide problem for drinking water treatment industry is the presence of algae in source water. Algae in drinking water supply can cause significant disturbances including taste and
Algae Removal at Water Treatment Plant High capacity separation equipment to assist in the removal of algae at a water treatment plant. A water supplier sought to improve their existing process further by removing algae from backwash water used within the water treatment process.
Algae Detection and Removal Strategies for Drinking Water
Algae Detection and Removal Strategies for Drinking Water Treatment Plants. With the many treatment and water quality problems associated with algae, this study presents its findings on: coagulation conditions, the utility of on-line in-vivo fluorescence, dissolved oxygen and pH measurements; effectiveness of conventional treatment; and effects of potassium permanganate preoxidatiion.
Thus, optimization of water treatment should be done in order to remove both hydrophobic and hydrophilic organic compounds, that can mitigate the formation of DBPs. Due to water quality problems and stricter regulations for drinking water treatment, there is a need for more efficient and still economical methods for the removal of NOM.

With more than 1,000 references all over the world, Actiflo® has been in use for municipal and industrial water and wastewater treatment for over 25 years. Actiflo® is ideal for drinking water and is particularly efficient in treating algal bloom, phosphorus removal, and reducing taste and odour associated with algae.
The performance of several enhanced treatment processes

drinking water treatment. It has been used continuously in drinking water treatment for about 100 years, beginning in Nice, France, in 1906. Since then, ozone was applied in Nice continuously, causing Nice to be called the place of birth of ozonation for drinking water treatment. Today, Europe has about three thousand ozonation facilities and ozone
Hectare-scale demonstration of high rate algal ponds
High rate algal ponds (HRAPs) are shallow, paddlewheel-mixed open raceway ponds that are an efficient and cost-effective upgrade for the conventional wastewater treatment ponds used by communities and farms the world over. HRAPs provide improved natural disinfection and nutrient removal and can be further enhanced by carbon dioxide (CO2) addition to promote algal growth which is often carbon
Although coagulation has historically been used for turbidity removal, drinking water regulations have emerged in recent years expanding the use of this process beyond its traditional role to include disinfection by-products (DBP) precursors removal. Effective removal of DBP precursors is the one of the major challenges in modern drinking water treatment.
