The Pan America Environmental STAX series is a family of above grade chemical coagulation/flocculation systems that can be provided for many applications where solids, metals  or other types of reactions are required. Applications can include: Food processing, animal processing, FRAC water, Industrial water, manufacturing wastewaters, refineries, steel mill process water, heavy equipment washwater.


  • Proven traditional design for reliability
  • Different sizes to choose from
  • Flow rates from 5 to 2000 + GPM
  • Construction: PVC,  304/316 SS
  • Many possible integrated options
  • Highly customizable design

Process Overview

The STAX designs are most commonly used wherever solids, oils, fuels, emulsion, metals precipitation, pH neutralization or other  pH reactions, reduction, oxidation and many other types of reactions are required in  for a  wastestream.

How It Works

The STAX Series flocculation systems are a pipe flocculator type of design that provides multiple-chemical reaction contact in a compact, small footprint design without moving parts, wearing components and no need for power. The STAX design uses water turbulence induced by a spiral piping network to mix chemical products into a wastestream.

The design eliminates the need for mixing tanks, mixers and electrical consumption. The process takes place under highly controlled, well-defined and optimised conditions.  No power requirements and no moving parts, which means minimal maintenance. Uniform mixing in the pipe cross-section promotes uniform flocculation. No mixing dead zones.
