New Vertical Pressure Filters

It’s a fact that contaminants exist, but there are some places where they cannot be allowed.

Water is one of them.

Naturally occurring radium, hydrogen sulfide, and iron kept reappearing in well two and three of Seneca, Illinois. With the leadership of Seneca's water operator, Paul Rivett and the engineer, Chamlin and Associates, the village renovated the existing facility, bringing contaminant levels greatly below EPA standards. 

Make Backwash More Effective

Simul-Wash™ 

Improve your overall filter performance and help reduce backwash frequency by optimizing every backwash.


Increased backwash frequency is recommended for:

• Excessive headloss (debris buildup in media)
• Diminished effluent water quality

About once a month:

• Gather a sample of backwash water halfway through Simul-Wash™ or a backwash.
