UNDERDRAWS FOR DESALINATION PLANTS

摘要

Severn Trent Services (www.severntrentservices.com) was selected to supply Tetra LP Block filter underdrain systems, for use in pretreatment filtration systems at two desalination plants in North Africa and South America. The Tetra LP Block system will form the floors of the rapid gravity sand filters that will treat sea-water prior to desalination by reverse osmosis membranes.
