  • Wastewater treatment for the metal industry

    Wastewater and process water treatment in the metal industry. Industrial waste water or circuit water in the metal industry can be broken down into many comprehensive, subject-specific areas. AWAS has developed various methods of treatment technology for the metal industry in the last 30 years. Generally we accept any environmental challenge and like to respond to individual problems.

    Water Testing for Automatic Rinse Tank Controls

    Proper rinsing is one of the most important steps in quality manufacturing or metal finishing. Plenty of low cost, good quality water for rinsing has been available in the past, so rinse water conservation has been largely ignored. Today, this is no longer true. Tap water costs have increased dramatically. Various new regulations are now in effect which limit the allowable volume of wastewater. Others require wastewater treatment. Still other laws tax the amount of water going down the sewer. These factors have all encouraged many manufacturers and platers to invest in automatic rinse tank control systems. Many platers using automatic control systems for the first time are pleased to discover a reduction in water usage of up to 80%.

    Hazardous waste treatment solutions for metal industry

    Sludge by-products from the metalworking industry have a high potential for recycling. Prolonged grinding processes can generate large amounts of highly valuable, alloy-rich sludge; consisting of metal powder and cooling lubricants. Inside our VacuDry system, the thermal separation of the liquids (hydrocarbons, eventually water) and solids (metal powder) takes place in an oxygen free atmosphere. This absence of oxygen ultimately eliminates material degradation by oxidation, and self-ignition or explosion risks. Operation under a low vacuum ensures the possibility to recover the cooling lubricants for later reuse. After the thermal treatment, for appropriate handling in the melting process, the metal powder is pressed into briquettes. With the econ VacuDry technology, 100% recycling of all ingredients is possible.

  • Metal finishing wastewater solution

    Metal finishing wastewater is a common application for ENCON Wastewater Evaporators. There are many types of wastewater generated in metal finishing. These include vibratory / tumbling wastewater, stamping wastewater, die casting wastewater and polishing wastewater. Metal Finishing wastewater cannot be simply flushed down the drain. Many companies choose to avoid the headaches of labor-intensive wastewater treatment technologies such as chemical treatment or filtration and simply pay to haul the wastewater. This however, can become quite expensive.

  • Wastewater treatment for the metallurgic industry

    Waste water in this sector has a high concentration of heavy metals, oils and products in decomposition. The oils and emulgents lead to foam production at the water treatment plants. The treatment of these oils is very important.

    Evaporation technology for mining & primary metals industries

    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.

  • Oil skimmers for steel industry

    AMBAR has supplied oil skimmers to the steel industry for over 25 years. The most common application for the Oil Mop skimmer is the removal of oil and grease form scale pits. Other applications include cooling ponds, retention ponds, in-ground sumps and waste water treatment pits. The advantage that AMBAR Environmental`s Oil Mop skimmers have over its competition is its versatility in a wide variety of applications. With the use of Tail Pulleys or Rollers, Rope Mop can be routed to provide excellent coverage of a pit, pond or tank. The mop can always be routed to the area where the oil collects the most.

  • Industrial water softening

    The presence of certain metal ions in water causes a variety of problems. These ions interfere with the action of soaps, lead to build up of limescale, which can foul plumbing, boilers, heating equipment. Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water extends the lifetime of plumbing and heating equipment. Softening of low TDS ( Total Dissolved Solids ) water is done commonly with a Strong Acid Cation ( SAC ) exchange resin operating in the sodium form and regenerated with brine. PuriTech`s latest development is a very performant continuous ion exchanger, based on PuriTech`s innovative ION-IX technology which is based on true counter-current ion exchange.

    Water Treatment Solutions for Radium Removal

    Radium is found naturally in uranium ores. It is an alkaline earth metal that decomposes in water and  it is over a million times more radioactive than the same mass of uranium. As a radiological hazard that emits alpha, beta, and gamma rays, it is a carcinogen.

  • Industrial water Copper removal and recovery

    Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys. Recycling is a major source of copper in the modern world. A combination of economic and regulatory factors are now at work to make metal recycle and water reuse very attractive.

  • Industrial water Gold and Silver

    Cyanidation is still the most widely used method to leach gold, using sodium or calcium cyanide as lixiviant. An anionic gold-cyanide complex is formed that is extractable by basic resins. Other metals present in the ore, such as silver and base metals ( copper, nickel, cobalt, zinc, iron, etc. ) are also leached in cyanide media. Selective ion exchange resins are designed to preferentially adsorb the mono-valent gold-cyanide species.

  • Industrial water Nickel Laterite

    Lateritic nickel ore deposits are surficial, weathered rinds formed on ultramafic rocks. Nickel laterites are a very important type of nickel ore deposit, they comprise 73% of the continental world nickel resources. They are growing to become the most important source of nickel metal for world demand. Nickel is a hard, silver white metal that has industrial applications related to its strength, corrosion resistance, high ductility, good thermal and electrical conductivity and catalytic properties. Its primary use is in manufacture of stainless steel, steel alloys and superalloys. The Nickel purification process is very complex of which a few are based on ion exchange, each taking care of a part of the full process cycle.
