UG
UG model separators are mainly suitable for underground installation in stormwater runoff applications.
Oil Water Separation Options
HYDRAPASS® – In large surface-area stormwater run-off, the “first flush” entrains the majority of the contaminants. The patented HYDRAPASS® can be used in conjunction with the HYDRASEP® to ensure that the “first flush” is treated and that excess flows are by-passed. The HYDRAPASS/HYDRASEP combination provides an economical and effective storm water run-off treatment.
