BioDoc Modulated Rotary Distributor Drive

Patented Design Features

SLOW DOWN THAT TRICKLING FILTER!

Back in the late 40's, English practitioners discovered the benefits of lengthening the dosing cycle to enhance the performance of trickling filters. Since 1987 an increasing number of U.S. plants have experienced the benefits of slowing down their trickling filters including:

Enhanced BOD5 removal

Reduced cyclic sloughing

Fewer odors (happier neighbors!)

But slowing the distributor is only the beginning. WesTech's Patented design incorporates a distributor drive designed to produce the optimal variation in rotational speeds and dosing rates enhancing performance with three important features:

A daily flushing cycle to clean the media

An operating cycle to promote deeper bio-growth

An operating cycle to encourage maximum wetting during peak loads
