4. What is HaloPure®?
HaloPure is the most unique and revolutionary drinking water
disinfection technology to come about in more than 15 years.
HaloPure is a novel, non-electric contact biocide manufactured in the
form of insoluble beads that kill viruses and bacteria on contact.
HaloPure is integrated into a wide variety of household point-of-use
water devices.
Disinfection is achieved without compromising taste, odor, or appearance

5. How HaloPure® is used:
We engineer a customized solution for your
needs
This solution is typically a cartridge or sub-
component filled with HaloPure media
The exact design characteristics of the cartridge are
specifically engineered to allow you to meet your
performance goals and claims

21. Objective
Create an add-on solution to existing RO
systems that prevents heterotrophic
contamination in the bladder tank
Problem
-Growth of HPCs in treated water post
RO system in the bladder tank
-No residual disinfection
-Customer complaints of fouled water
-Increased regulatory compliance
requirements
Case Study: RO HPC Control

22. - Designed in-house supplementary HP
disinfection “cage” into GAC T-33 cartridge
- Water passes before entering
tank, and again before faucet exit
Solution

23. Results:
99% average
reduction of HPCs

Problems reduced
Full compliance
with regulatory
standards

24. Objective
Eliminate biofilm that fouls nearly all
water piping and tubing
Problem
-Long-term formation of biofilm
-Biofilm propagates backwards as well
as forwards through a water system
Case Study: General Biofilm

29. Case Study: Inline Cartridge
Objective
Design a primary disinfection
cartridge compatible with
commercially available housings
Problem
-High pressure drop in existing
filtration products (requiring high
inlet pressure)
-Clogging and low lifespan of
existing filtration products
-Existing filtration products can’t
deliver on disinfection (bacteria
and virus reduction)

30. Solution
Format HaloPure packing to fit
standard 10inch water filter
housing, using Plekx spiral
wound membrane technology.
Results
-Continuous 3 log reduction in
E. coli over 15,000 L

at 3lpm without clogging issues
-Use as before, retrofittable to
existing base

31. Case Study: Universal Cartridge

32. Case Study: Safe Storage
Problem:
Storage of water purified by any means often leads to re-
contamination, from dirty hands, dirty vessels & environmental sources.

33. Solution:
Protect the purified water in storage by delivering
enough halogen to inactivate microbial
contaminants.
