WWW™ miGRATE

The industry’s latest advancement in process intensification, WWW™ miGRATE is an advanced, fully green process that utilizes a renewable and fully compostable carrier. This carrier is derived from natural biopolymers and hemp fibers to produce extruded carriers — all identical in size, shape, surface area and density.

Better SVI and Uniform Biofilm Growth

Media uniformity provides a platform for stable and consistent biofilm growth. Combined with cohesive density, the media settles at an advanced rate, improving the sludge volume index (SVI) of both carrier and suspended solids.

The uniformity of biofilm growth and settleability also improves design and modeling, leading to a better, more predictable design. This media advancement provides a 20-year guarantee from the media breaking down or degrading.

Increased Capacity and Settleability

At a low fill fraction ranging from 1 to 5%, WWW™ miGRATE is operated at a low solids residence time (SRT) and low dissolved oxygen (DO) to increase capacity, reduce effluent nutrient concentrations, improve settleability and reduce overall energy cost.

Process Intensification at a Minimal Cost

Typically retrofitted into existing infrastructure, decoupling SRTs between the fixed and suspended biomass, WWW™ miGRATE is capable of overall process intensification with minimal engineering and construction costs.

A Flexible Solution

Accompanied with a 20-year guarantee on the media, WWW™ miGRATE has multiple selector options — from rotary drum screens to static screens — capable of providing complete media capture.

Integrated with WWW™ inDense™, a screen-cyclone combination provides optimal selection of both nitrifying and phosphorous organisms. Further integration with WWW™ AvN® provides total control of both SRT and DO to optimize process intensification.
