Acid Regeneration Process The commercially most relevant field of application for HCl regeneration processes is the recovery of HCl from waste pickle liquors from carbon steel pickling lines. Other applications include the production of metal oxides such as, but not limited, to Al2O3 and MgO as well as rare earth oxides by pyrohydrolysis of aqueous metal chloride or rare earth chloride solutions. A number of different process routes are available. The most widely used is based on pyrohydrolysis and adiabatic...

Local authorities incinerate domestic waste and other kinds of waste that typically include plastics, batteries and a diversity of unknown compounds. These may all produce acidic and other toxic emissions. Therefore, efficient flue-gas cleaning systems are needed to prevent their release into the environment.

In industrial manufacturing companies, before a new process comes on-line, it is important to measure the toxicity of the effluent stream. This is especially the case for companies who treat their own waste. From the toxicity value (EC50) obtained, it may be a cost-effective solution to simply discharge the effluent to the treatment works at a slow and defined rate to minimise damage to the activated sludge. Following a period of acclimatisation it is often possible to increase feed rates to the plant and this...

Th turn key plant is composed by three different wet stages. The first stage is a venturi jet scrubber to collect dust and particles, then the second and third stages are deputed to absorb bad smells, such as H2S, Ammonia and Ammines. The absorption takes place thanks to the injection of chemicals (such as Sulphuric Acid, Sodium Hypochlorite and Sodium hydroxide.

Manufacturing, metal fabrication and metal finishing require multiple washing processes to remove residue, oil, acids and other lubricants and contaminants before during and following various process steps. This generates large volumes of wastewater containing alkaline, acid solutions, heavy metal wastewaters, paint, plating residue wastewater, and other metal fabrication wastewaters. Wastewater and wash water from spills and floor cleaning must also be properly disposed. These manufacturing waste waters cannot...

In many fields of water treatment Körting ejectors are applied as gas introducing systems; Waste water aeration in aeration tanks and SBR-Plants. Introducing ozone or oxygen. Pressurised dissolved air flotation. Disinfection of potable water and de-acidification. Further applications are: Diluting and conveying acids and lye during the process of regenerating ion exchangers.

Fertilizer Plant Clean‐up and General Maintenance. Vac‐Tron vacuum excavation models are currently being used at various fertilizer plants for general clean‐up and removal of muriatic acid waste. It is highly recommended that the inside of the debris tank and filter housing be protected with a coating that will resist the corrosive effects of the acid. Proper clean up is a must.

Flue Gas Desulfurization (FGD) involves the removal of sulfur dioxide and other acids from flue gases. Typical sources of acid gases include fossil fuel boilers, waste combustors, and other industrial applications such as refining and smelting. The Macrotek wet and dry FGD systems can achieve over 99% acid removal by using a variety of reagents, including caustic, sodium carbonate, lime and limestone, and waste alkaline solids or liquids.

Plating rinse wastewater is one of the most common applications for ENCON Wastewater Evaporators. Wastewater from plating rinse tends to be rather corrosive. The chemistries used in the plating process can include a wide range of acids such as nitric acid, chromic acid, hydrochloric acid, sulfuric acid, hydrofluoric acid, as well as other non-acid chemistries like ammonium bifluoride and nickel sulfamate. Typically, the waste stream has a transparent, relatively clean look because they are dilute and the contaminan...

SorbEater is a synthetic super-absorbent with the highest oil recovery ratio of ANY known absorbent material resulting in less product required and less product to dispose of. This provides significant savings on the costly disposal fees associated with hazardous waste. It is highly effective on fresh water, soil, sand and sea. During development it outperformed the traditional organic peat products in every test. Ideal for: Any hydrocarbon spills or contamination. It has been used successfully with...

Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen, used for industrial or domestic purposes to manage waste and/or to release energy. It is widely used as part of the process to treat wastewater, like Upflow Anaerobic Sludge Blanket (UASB) reactors. As part of an integrated waste management system, anaerobic digestion reduces the emission of landfill gas into the atmosphere. Anaerobic digestion is widely used as a renewable energy...
