Liquid / Solid Separation Systems

Screening, Gravity, Flotation, Dewatering & Accessories

PEWE SHS SuperSkreen Design:

The side hill screen system utilizes a parabolic wedgewire screen for separating coarse suspended solids from the water.

PEWE SHS Operation:

The side hill screen  operates by feeding the   solids laden influent water to the headbox.  The water then flows over a  distribution weir onto the steeply angled screen surface.  Solids ride the screen to it’s base and fall  off at the discharge lip into a waiting receptacle  for disposal.  The water passes directly through the screen to a collection pan.

PEWE EFS SuperSkreen Design:

The external design utilizes a cylindrical wedgewire screen for separating coarse suspended  solids from the water.

PEWE EFS Operation:

The externally fed screen system operates by feeding the solids laden influent water to  the headbox.  The water is then evenly distributed across the full length of the upper outside surface of  the rotating drum. The solids are picked up by the drum and carried to a fixed  doctor blade for removal. The  water passes through the drum and flows out the bottom. Scraped solids are deposited in a waiting receptacle.

PEWE IFS SuperSkreen Design:

The internal design utilizes a cylindrical wedgewire screen for separating coarse suspended  solids from the water.

PEWE IFS Operation:

The internally fed screen system operates  by feeding the solids laden influent water to the headbox. The water is then distributed  evenly onto the interior sidewalls  of the rotating drum.  Solids collect onto the interior drum surface as the  water passed through the screen into a catch pan.  Flights convey the solids forward, further dewatering them as they “roll up”  and out of the barrel.

  Side Hill Screens……..…….……. Simple, Economical

  Externally Fed Screens……….. Low Flow, Oily Solids

  Internally Fed Screens….…..High Flow, High Solids
