The Pellu Wastewater
Process The “Pellu” bird only catches it’s prey in clean, clear, odorless water. This is the goal of PellU Svstems to provide colorless, odorless, clean water using one or a combination of six dif- ferent Pellu chemicals, depending on the profile and complexity of the solution. It removes all heavy metals, is not pH sensitive, and is highly efficient in the presence of interfering agents such as ammonia, sulfates and EDTA. This process is extremely cost effective, and time saving.
