PET (ASX) Environmental Rejuvenation 2

Originally posted by edshann: ↑

Carbonxt (CG1) Is treating phosphorus in the USA in a different way to PET using activated carbon. Rather than treat lakes, it is experimenting with using a pilot plant to treat water flowing into water bodies. It will be interesting to see which method gets most contracts. This is a different way of addressing the algae problem.

From CG1 presentation:

"Phosphorus Reduction in the Community as Prevention
of Eutrophication and Harmful Algal Blooms
Introduction
Phosphorus and nitrogen are critical components of natural growth. These
nutrients move through the environment and can accumulate in water
bodies. Anthropogenic releases of nutrients include wastewater treatment
discharges, fertilizer runoff, and industrial discharge.
Once the water bodies accumulate excess nutrients, algal blooms begin to
grow and can either cause the water body to turn eutrophic (killing other
flora and fauna).

Problem Statement and Motivation
In the USA, roughly 34 billion gallons of water per day are processed as
wastewater. That water is either directly discharged into surrounding
waterbodies or reused for beneficial practices.
Reused water can be beneficially used to irrigate urban landscaping or
agriculture, recharge watersheds, and/or non-potable industrial processes.
Much of this water, is treated to moderate levels, but some still contain
elevated nutrient concentrations and can lead to eutrophication and algal
blooms in surface water.
HydRestor® is intended to be a technology deployed by wastewater
facilities and municipalities with elevated phosphorus concentrations to
reuse their reclaim water.

Wastewater and Water Reuse
Statistics
34 billion gallons of water per day are
processed at US wastewater treatment
facilities – US EPA 22
34% of “major” US WWFs have Nitrogen or
Phosphorous regulations.
10% of “non-major” US WWFs have Nitrogen
or Phosphorous regulations.
Data based on 2016 US EPA Reporting
5 billion gallons of water per day are
beneficially reused for urban irrigation,
environmental recharge, or other industrial
purposes. – Water Reuse Association 2022
32 states have regulations for urban reuse,
17 states have regulations for
environmental recharge.- 2012 EPS Report
60% of Florida impaired waterbodies are
related to nutrients or dissolved oxygen
issues. - 2022 FDEP Report

HydRestor® – Phosphate Recovery Technology
Example Case Studies
 The HydRestor™ technology is a pelletized activated carbon media, specifically created to reduce
nutrient loading in water and reduce phosphorus concentrations.
 The ready-to-use filter media is loaded into beds and water is then passed through with necessary
residence times needed for phosphorus adsorption. The technology is formulated to target the removal of
phosphorus from a variety of water sources, including wastewater, stormwater, and industrial processes.
 The HydRestor™ was selected for an extensive research program funded through the state of Florida and
local municipalities. The award funds $400,000 of testing and will treat over 8 million gallons of water.
HydRestor® pellets were used in a large-scale system
that treated nutrients through a 1 million gallon per
day flow stream.
A pilot trailer is being manufactured in order to take
HydRestor® mobile. Simple plug-and-play configuration
leads to more availability of pilot testing and continuation
of demonstrated performance."
