Proven technologies for the Power industry Actiflo The Actiflo process is an ideal solution for recycling valuable process water, providing boiler feed, product water and cooling tower makeup water to the power industry. Actiflo has also proven to be very efficient for algae removal. Actiflo Softening is a technological breakthrough in water treatment, offering some unique advantages over traditional clarification systems with the chemical precipitation of: Hardness Alkalinity Silica And other constituents (e.g., heavy metals) Demineralization units Safe systems that meet your specifications for all situations Zero Liquid Discharge (ZLD) Reduced environmental impact Volume reduction, recycling of valuable water, and reuse CoLD Process to achieve ZLD difficult coal-fired wastewaters Multiple Effect Distillation (MED) Can be coupled with Reverse Osmosis desalination for an innovative, energy-saving hybrid solution World leader in thermal desalination through subsidiaries like Sidem and Entropie, Veolia Water Solutions & Technologies has provided more than 80% of the world installed capacity of desalination plants using the MED process. Multiflo & DAF Flotation for seawater Combined technologies for a safe system Efficient process for removing total suspended solids (TSS), color, algae and heavy metal co-precipitates Suitable for treating water with an average to high turbidity level (10-4000 mg/l TSS) Condensate Polishing Plant State-of-the-art resine regeneration technology
Understanding your treatment needs 1. Pre-treatment For all types of feed water including sea water, ground water, surface water and wastewater (recycling). Removal of suspended solids, colloidals, organics, iron and manganese from water 2. Boiler feed water treatment Processes and technological solutions Reduction of impurities entering the boiler system that cause reduced heat transfer, increased fuel consumption, steam contamination, carry-over, condensate corrosion, and turbine deposits which can all lead to a loss of production 3. Condensate polishing Removal of impurities from the condensed steam Reduction of suspended solids, iron and ionic impurities that lead to increased corrosion and downtime 4. Cooling tower water treatment Cooling tower sidestream Sidestream filtration, water treatment chemicals and associated services to help power generation companies effectively manage their cooling towers. Reduce scaling and deposition, minimize microbial activity and more specifically legionella control Cooling tower blowdown Technologies to treat or minimize blowdown water, in order to avoid corrosion and organic material in cooling towers due to excess concentration of contaminants. Minimize water use Zinc and chromates removal Silica and metals removal 5. FGD wastewater Flue gas desulfurization (FGD) scrubber effluent from coal-fired power generation requires varying degrees of treatment depending on the type of coal, water sources, and environmental regulations, in order to reduce: Particle matters and Gypsum de-saturation Heavy metals Environmental impact Volume reduction, recycling of valuable water, and reuse
