EVALED - Evaporator - Veolia Water Technologies Italia Spa applications
Treatment of wastewater coming from surface cleaning and surface finishing processes. Water reuse, disposal cost reduction, sustainability. Surface treatment processes are widely used in the production of metal parts; they can be functional, as those aimed at protecting from corrosion or wear; aesthetical, like painting or coating; or both, as aluminum anodizing.
Treating metalworking wastewater means the separation of oils, heavy metals and suspended solids, water reuse, disposal costs reduction and sustainability improvement. Mechanical workshops generate effluents containing lubricating oils with significant levels of COD (Chemical Oxygen Demand), hydrocarbons, metals and suspended solids. These workshop wastewaters may come from a variety of operations such as cutting and drilling, molding, cleaning of mechanical parts, paint shops, maintenance, drainages from settling and sludge tanks, and from a variety of industries such as automotive, aerospace, furniture, appliances, and many others.
Landfill leachate, in collectors, landfills and incinerators, is the outcome of percolation and leaching phenomena from stockpiled waste. The leachate produced by the waste in the landfill is an extremely pollutant effluent: it contains a significant percentage of ammonia, COD, heavy metals and salinity (chlorides and sulfates). It is therefore hard to treat and requires high effective treatment processes to comply with the very strict limits for discharging operations. Our wastewater evaporation technologies for the landfill leachate water treatment are an effective solution in treating highly polluted, concentrated landfill waste, very difficult to treat by traditional processes.
The oil and gas industry faces water and wastewater treatment specific challenges. EVALED® evaporators represent an effective solution for both downstream (onshore and offshore) and upstream plants, allowing ZLD (Zero Liquid Discharge). Upstream and downstream wastewater treatment for environmental regulations compliance.
Water is essential component in the mining and steel industries. The main needs under this aspect are optimizing the management of the resources, improving productivity by treating available water for specific production process requirements and managing environmental risks by treating contaminated pond and underground mine water to remove heavy metals, arsenic and other contaminants for safe discharge into sensitive environment. Steel, Copper, Aluminum, Lithium. Wastewater treatment to remove highly polluting elements and reuse water.
Different industries with many different challenges to face. All of them have to find efficient and effective solutions to optimize the available resources for an ever more high competitiveness and, contextually, to comply with the most stringent regulations about the protection of the environment.
