HI IMPACT
When removing high levels of organic
materials from screenings is the objective,
our SPIROWASH HIGH IMPACT is the most
appropriate choice.
An important design feature of this unit is the
addition of a wash-box (incorporating our
unique high-speed non-rag-balling impellor
design), which is able to dislodge as much as
95% of organic material from the final
discharged product.
