maintenance, as opposed to powering down the entire pro-
cess. Through pilot validation testing, Disa will continue to
scale and improve continuous unit designs.
Prototype Header Units—Various configurations
of header units, composed of collision chambers and the
systems that feed the chambers, are being designed and
tested as HPSA systems scale. Specific modifications are
being done to improve the performance of the systems the
designs are focused to increase collision frequencies, reduce
operational costs, and increase operational availability of
the systems. For example, increasing the number of active
nozzle pairs in a unit directly increase the collision fre-
quency in the system. The developed configurations adapt
the number and orientation of the jets, manifold types and
geometries, and chamber inter-nozzle distances—all which
have been found to affect the performance of the chambers
(Weaver, 2024). A prototype test unit is shown in Figure 6,
the unit features four collision chambers that operate from
one pump. Header Units are also being designed to increase
operational availability by developing integrated bypass
systems, that also allow for in-operation repairs or mainte-
nance to occur. These prototype header units are designed
with the functionality to operate on continuous units, on
batch units, or in the shown case, on a hybrid batch unit at
2–3 metric tons per hour in continuous operation.
REMEDIATION APPLICATIONS
Overview
A significant application for the technology is for environ-
mental remediation, especially in remote, disadvantaged
communities. Currently, the only commercially avail-
able option to remediate contaminated soil is to haul all
the material offsite or to cap all the material onsite. The
modular, scalable, and transportable nature of the HPSA
