ASTRASAND®COMPAQT
ASTRASAND®COMPAQT is a new and improved continuous sand filter, developed for different types of water, such as process, waste, surface, cooling and ground water.
ASTRASAND®COMPAQT works as a continuous process, in which the filter bed is cleaned during the filtration operation. Interruptions are eliminated through this continuous self-cleaning process.
ASTRASAND®COMPAQT Sand filtration is a proven filtration process that can be utilised for many types of wastewater, with unit capacity varying from only a few to several thousand m3/hour. It is a highly efficient and reliable system, which offers a short lead time and a better sand velocity distribution than conventional sand filters. With a non-metal tank and use of materials that are resistant to chemicals and corrosion it also offers lower operational and maintenance costs.
