A wide range of applications for dt technology
Applications for pall filtration equipment fall into the following categories:
• the remediation and softening of groundwater, particularly at hazardous waste sites.
• the desalination of seawater on boardships, at resorts - or offshore oil/gas production platforms.
• the filtering and cleaning of leachate at solid waste landfills.
• the filtering and softening of surface water
• the treatment of industrial wastes to permit safe discharge and water reuse.
• the treatment of cooling tower boiler blowdown.
Open channel technology
• less susceptible to fouling and scaling
• modules are easy to clean
• suitable for silt density index (sdi) up to 5/15
Easy maintenance
• module can be opened
• module and membranes can be investigated
• single membranes can be tested for best cleaning procedure
• single membranes can be investigated at lab (edx, microscope)
Features of pall dt reverse osmosis systems
• modular expandable design with one or multiple stages
• recovery rates achievable by dt modules with staged ro pressure (base 18ms/cm)
• high pressure units maximize permeate yield (recovery rate)
• mobile containerized units or in situ installation options
• no mechanical chemical pre-treatment necessary
• small footprint
• installation complementary to existing treatment plants
• ‘plug & play’ installation with short start-up period
• capacity ranges from 1 – 25 m3/h per line
• short or long-term rental opportunities
• economic module exchange
• worldwide service
