WW1 Effluent Filter

Clarus Environmental’s WW1 Effluent Filter helps prolong the life of an on-site system by filtering solids which may cause harm to downstream components such as drain fields.  Used in residential applications where the maximum flow is less than 5.7 m³/day, the WW1 effluent filter includes a patented bypass protection sleeve to keep solids in the septic tank during cleaning.  The deep pleated filter design offers highly effective filtering and solids retention.  The filter is available with or without a 110mm sanitary tee for easy installation in new or existing septic tanks and comes with a lifetime warranty.
