VEOLIA Water Treatment – Evaled

Evaled offers a family of effective solutions for water reuse and zero liquid discharge (ZLD), waste volume and disposal cost reduction, and effluent treatment for industrial water and wastewater treatment.

Design & Features

• Efficiency and simplicity: excellent quality of the distillate produced, suitable for factory multi-purpose reuse; high level of concentration of the polluting fraction for significant reduction of disposal costs.
• Waste-to-energy water treatment by-product seperation provides an effective alternative energy option to reduce energy costs, CO2 emissions and replace fossil fuels.
• Reliability and cost-effectiveness: low maintenance requirements and energy consumption.
• Versatility: can treat feed water with little or no pretreatment, including hazardous and difficult streams.
• Zero liquid discharge (ZLD): distillate can be recovered and recycled as process water (when possible) or for other factory purposes, helping plants meet discharge obligations and providing a potential income or saving source.
• Component recovery: valuable materials can be separated or recycled, including precious metals or Active Pharmaceutical Ingredients (API).
• Eco-friendliness: low carbon footprint. This allows us to meet and exceed the discharge limits required by local environmental legislation.

Materials

• Austenitic Stainless Steel
• Austenic weakly bound structure, non-hardening, non-magnetic.
• The low percentage of carbon in this alloy reduces the risk of intergranular corrosion at high temperatures.
• Uses: alkaline liquids, acid liquids (pH>4) with a low percentage of chlorides, oil emulsions, liquids from flexographic printing.
• Superduplex stainless steel
• Austenic-ferritic structure, magnetic.
• The high percentage of chromium gives excellent resistance to localized corrosion.
• Uses: acidic liquids (pH>3) with high chlorides and metals content, galvanic wastewater, landfill leachate.
• Nickel Alloy
• High flexibility Cr-Ni-Mo steel.
• The low carbon content ensures resistance to the formation of carbides at zones exposed to thermal variation. It has excellent resistance to localized corrosion, both in oxidizing and reducing environments, even at high temperatures.
• Uses: very acid liquids (pH>2) with high content of chlorides, fluorides and metal, anodizing wastewater, special applications.
• Silicon Carbide (SiC) (PC type only (KT-Series))
• Chemically inert material resistant to almost all agressive substances.
• It is usually matched with another chemically inert material, PTFE, a fluoride co-polymer used for coating the inner surfaces of the boiling chamber.
• Uses: pickling wastewater, chromic acid recovery and aggressive liquids.

Option

• Standard Option: Meets current USP & Ph Eur requirements for Purified Water
• UF Option: Meets current Ph Eur requirements for Highly Purified Water
