How does this compare to evaporating my wastewater?

Extran Ultrafiltration Systems typically have much lower operating costs than evaporation. Extran systems are capable of handling wastewater with emulsified oil, free oil and solids that can lead to extensive maintenance for evaporators.  Rather than throwing out water after one use, Extran can also help you re-use specific types of wastewater, such as wastewater generated from floor cleaning and parts cleaning.
