ENVIRONMENT & WASTE
conditioning of dusts, sludge and liquids
Dust, ash, various bulk materials, or sludges are humidified, liquefied, stabilized, or granulated. The result is a portable end product for disposal or Recycling.
thermal treatment of soils, sludge, suspensions or other hazardous waste
AVA develops and delivers turnkey (mobile) complete plants for preparation of contaminated recyclables and waste, always perfectly adapted to your needs.
Sample applications include the treatment of contaminated filters and decanter sludge, treatment of contaminated soil and drilling mud, treatment of mercury waste, or solvent recovery.
handling of radioactive materials
AVA supplies specially designed evaporators and dewaterers for ion exchanger sludges and resins generated in operational nuclear power plants. These and other concentrated, highly radioactive residue products can be cemented with specially designed AVA mixing technology before placed into final storage. For applications involving the dismantling and disposal of contaminated sites, contaminated waste water and sludge are concentrated in AVA evaporators, which reduces volumes and thus disposal costs.
sterilizing of hazardous waste
AVA mixing reactors are ideally suited for steam sterilization of hazardous waste. The reactor acts as an autoclave, and temperature as well as pressure can be flexibly adjusted according to the applicable standard. Typical tasks include the treatment of infectious waste water, hospital, or laboratory waste. AVA sterilizing plants are also often available in a mobile version, for example, for use in field hospitals or on cruise ships.
furnace outlet conveyors
Vibratory conveyors type CCU leaf spring design, are utilised for collecting and transporting the hot slag directly from the furnace discharge points. These vibratory conveyors are also used for the transportation of wet slag. Ideal for 24 hour continuous operation, the unbalanced motor driven units are usually 800, 1000 or 1250mm wide, with lengths up to 20M
oversize removal scalpers
Vibrating scalpers type SCU are used to scalp off the oversize material, prior to the transportation of the waste material to the slag pit. The are usually situated directly after the furnace outlet conveyors.
slag pit loading conveyors
Type CCU unbalanced motor driven vibratory conveyors are used for slag pit loading. They are suitable for handling either hot or wet slag, and allow for 24 hour continuous operation. Their design allows for either floor mounting or overhead suspension Usually 800, 1000 or 1250mm wide, with lengths up to 6M.
Instead of loading into slag pits, type CCU unbalanced motor driven vibrating conveyors on turntables allow for an even distribution of waste materials into containers and skips. Units up to 6M long can be turntable mounted.
Incineration ash and fines which could cause environmental pollution, can be collected and transported in totally enclosed and fully dust proof type COU vibratory tubular conveuors. Dependant upon the plant layout, the unbalanced drive motors can be mounted either under or over the tube. These are available in 6 standard diameters between 160 - 560mm, with lengths upto 10M.
