BTII has created drinking water purification systems (solar or minimal electric) called Caripur H2O, a line of point-of-entry devices that use reliable water purification methodologies to remove virtually all pathogens, chemicals, and heavy metals, from drinking water.
Each unit is fitted with our patent pending Binary Star™* water alert technology, multiple sensors that measure water quality, consumption patterns, and system operation,
CARIPUR H2O™, the Best Home Water Purification System
Caripur captures a 360-degree perspective of raw data collected from multiple sensors. For the customer, this can quickly identify failing infrastructure, reduce water loss, measure consumption, and measure asset health. In addition, the data can unlock operational efficiencies, inform proactive maintenance opportunities, and guide long-range planning and investment strategies.
The Bondurant Advantage of having Internet of Thing (IoT) water purification is that we can worry about your water, so you don’t have to. Imagine having an entire team of people dedicated to ensure our every precious drop of your drinking water is clean, safe and delicious and your system is operating properly. Our devices are capable of being remotely monitored, allowing for real-time tracking to monitor for any current and potential maintenance and operational issues.
The system is factory assembled and housed within a weather-proof 304 stainless steel or polypropylene copolymer case and includes an internal membrane disinfection system, fused sensor multispectral water quality sensor, self-cleaning capabilities, and Binary Star® Technology.
Even though it is essentially an in-line filter, utilizing external forces (well pump, cistern pump, water authority feed), to push water through it, Caripur H2O was designed to operate should those sources fail. It can run using its own internal pumps on AC/DC, solar energy, and/or an internal rechargeable backup battery. This capability gives our technology the ability to provide drinking water, even when there is no power.

Caripur H2O utilizes ultrafiltration (UF) membrane filtration at its core. In UF, hydrostatic
pressure or gravity forces a liquid against a hollow fiber threaded membrane used to separate the
suspended particles and impurities from water. The membrane is similar to that used in reverse osmosis
(RO), but with larger pore sizes.
Granulated activated carbon (GAC) is made of coconut husks that have been heated to a high temperature
in the absence of oxygen and then granulated. This increases the surface area of the chemically reactive
carbon, allowing it to absorb and adhere to and trap great amounts of certain chemical contaminants in
water.
IX is a process that selectively removes contaminants from water by swapping out ions of similar
electrical charges on a resin bed. This way, IX targets specific substances for removal based on their
ionic charges. Softeners are a common ion-exchange method, extracting the minerals that cause limescale
from hard water.
Water passes through a quartz tube that is irradiated with UV radiation from a UV lamp. UV radiation
kills bacteria and other pathogens by destroying their DNA or RNA.
RO uses a semipermeable membrane that removes dissolved and suspended impurities. High pressure is
applied on one side, forcing the water across the membrane and moving from an area of higher impurity
concentration to that of a lower one. This process leaves behind contaminants that have larger particle
sizes than water molecules.
Primary purification mechanism
Physical separation based on size.
Chemical separation based on absorption and physical separation based on the size of the IX surface.
Chemical separation at the IX surface.
Physical damage from UV separation-based radiation.
Physical separation based on size.
Contaminants eliminated
Removes bacteria, viruses, cysts, parasites, chlorine, pesticides, metals, and macromolecules larger
than the membrane pore size.
Removes coarse particles, organic compounds, and pollutants, including chlorine, pesticides, and
herbicides.
Softeners reduce water hardness via cation exchange, removing calcium and magnesium for sodium.
Kills or renders dormant water-borne bacteria and viruses, but their dead bodies remain in the water.
Removes bacteria, viruses, cysts, pharmaceuticals, some salts, metals, and pesticides.
Contaminants not eliminated
Dissolved salts, arsenic, and fluoride.
Bacteria, pharmaceuticals, fertilizers, and heavy metals.
Bacteria and viruses, pharmaceuticals, and suspended solids.
Coarse particles, salts, volatile organic compounds (VOCs), nitrates, and heavy metals.
VOCs, salts, and metals with small atomic sizes.

Long-term maintenance and performance
The membranes in Caripur H2O are continually cleaned and are projected to last a minimum of 5
years before minor maintenance is required.
The filter cartridges require frequent replacement (from 2 weeks to 1 month) when they are saturated
with contaminants and are no longer effective.
IX resins must be replaced or regenerated, as saturation and clogging compromises service life over
time.
The UV lamp requires regular replacements as the bulb gets dimmer. The quartz glass tubes also need to
be cleaned to remove algae, scale, and other deposits.
Long-term performance is poor, and breakages in the membranes are not easily detected, thus requiring
regular replacements.

Uses the same amount of energy as a 60-watt bulb.

Additional features
Sensors monitor every aspect of the water, the system function, and it has a battery backup and internal
pumps in case of power failure.
Sometimes paired with an RO system to remove more contaminants from the water.
Generally combined with other purification methods that first filter the water to avoid clogging and
damaging IX resin beds.
Sometimes paired with RO to remove dead bacteria from water or active carbon to improve purification.
Always comes with pre-filtration and sometimes post-filtration to remove contaminants that might damage
the membrane.
Remarks
UF is not fundamentally different from RO except in terms of the size of molecules that it retains.
UF also does not produce much wastewater, generally around 2%.
Over time, bacteria tend to colonize the surface and go downstream into the filtered water.
Although a one-time purchase of an active carbon filter is cheap, it is expensive to maintain in the
long term due to frequent replacements.
Certain chemical disinfectants can degrade IX resins, so care must be taken to remove such materials
upstream of any IX columns in order to prevent excess resin replacement costs.
Most bacteria can only be targeted with a certain wavelength. Sometimes, the UV tube gets a good shot
but will not kill the bacteria.
UV also does not work with muddy water; it requires clear water to function.
In an RO system, natural minerals are removed along with contaminants from water. It also rejects a
large amount of water in the process, up to 80%.
RO membranes are mostly imperfect; they come with breakages and small holes from the get-go.
