A Hydro Sieve Static Screen will work very well for your application. I have used them for several applications in breweries on water reuse systems, like cooling towers and tunnel pasteurizers. By the way, the solids can be added to the spent grain.
Operating principle
Its operation is based on the Coanda effect. This means that the liquid to be screened forms a hydraulic attachment to the bars of the screen plate. These bars, with triangular sections, have rounded angles and a wave configuration, as opposed to being straight. Thus, the liquid passes through the slots while the separated solids stay on the front face of the screen plate. The screen plate has three distinct angles. This arrangement ensures:
- Elimination of the majority of the liquid
- Deceleration of the screenings
- Drainage
The screen plate is supported by a frame that initially ensures quietness and even distribution of the effluent over the entire unit width and then accelerates the liquid down the screen plate. The filtered liquid is collected in the screen base. The screen plate and the frame form the HydraSieve screen.
Advantages from simple design and robust construction
- No moving parts, no motor
- Meager installation costs, no maintenance
- It only requires periodic cleaning
- Quiet operation
- The wave shape of the bars provides the HydraSieve screen with its self-cleaning effect.

Dear Michael:
We ended up using a plate and frame filter in Germany to filter out particulate from our wastewater stream in order to reduce TDS. This system was remarkably effective, and we discarded the solids as solid waste after drying them.
Another possible solution, although more labor intensive is flocculation in a holding tank.
Hope this helps.
Cheers,

Subject: wastewater screening
hello:
does anyone have a simple wastewater screening system in place that removes hop/trub particulate?
ideally we are looking into something like a waterfall wire screen that we can install in a passive format and not have to rely on a lift station.
we would want to hook up the outlets of the kettle/whirlpool and dry hopped fermenters straight through it.
