A major use of organic polymers in water treatment is as a coagulant aid to bridge the coagulated particles formed when an aluminium or iron salt has been used as the primary coagulant. An appropriate polyelectrolyte can increase floc size; a strong dense floc of regular shape is preferred. The large aggregates that form then settle more rapidly.

POLYELECTROLYTE TREATMENT - AN APPROACH FOR WATER QUALITY

The raw water treatment plant at Narora Atomic Power Station (NAPS) handles 70-120 million litres per day (MLD) of raw water contaminated with suspended material resulting from colloidal clay, soil, organic matter, decaying vegetation etc. Such large quantities of water are treated by two clariflocculators.

Practicalities In The Use Of Polyelectrolytes - Water

Cationic polymers in common use in the water industry, such as polyDADMAC and ECH/DMA, generally produce little in terms of disinfection by-product formation when the normal levels of polymer utilised in water treatment are exposed to conventional amounts of chlorine [136]. This is illustrated in Fig. 2.

Olive Oil Mill Wastewater Treatment Using a Chemical

Olive oil mill wastewaters (OMW) are recalcitrant to biodegradation for their toxicity due to high values of chemical oxygen demand (COD), biological oxygen demand (BOD), and phenolic compounds. In the present study OMW, collected in southern Italy, were subjected first to a chemical oxidative procedure with FeCl3 and then to a biological treatment.
