The Caripur is an inline purification filter that allows your external cistern pump or water authority pressure to push water through our membranes. So it is essentially a passive system, using almost no electricity until needed. Employing, primarily ultrafiltration membrane technology, our device presents a physical barrier to prevent the passage of organic and inorganic material.
All of the Caripur units are equipped with the components and membranes that are made in the USA in ISO 9001:2008 certified facilities, meet MIL-STD-810F specifications, and designed for continuous run.
It is a Point-Of-Entry device, designed to purify water in individual homes and businesses, it can operate off of solar power, so remote locations can also benefit.
The Caripur is built to operate under harsh climate conditions, including from deserts to very humid regions.
We customize the units for their specific geography, and we provide all commensurate attachments for said environments. Water temperature cannot, however, exceed 113◦ F (75◦ C).
Depending on the type of unit, the required amount of water, the amount of power supply, and additional features, the price can vary. Please contact us directly for pricing.
The units reside inside of custom-formed, high-strength polymer cases, which are engineered to protect the components from the harshest conditions. The units are specially designed and manufactured to work outdoors and under harsh weather conditions. However, some form of protection (a roof or indoor installation, or a storage facility) can extend the life of the unit. We provide our units assembled in standardized Uni-Pak 40″ x 48″ x 45″ pallet pack containers.
The Caripur produces rejected liquid and varies depending upon how frequently a flush is required. As a general rule, we suggest 2% of the water is rejectant. Since our system does not use acid and antiscalant dosing, the concentration of concentrate is not very high and can be used directly for irrigation. However, use for irrigation depends on the type of salt present in the rejected streams and the concentration of salts. If rejected streams contain heavy metal salts such as chromium salts, then this water cannot be used for irrigation.
Alternatively, placement into an open-air pit or hole to dewater the rejectant can be done so that it is in a more concentrated form for disposal once the water has evaporated.
There are times when the unit is standing for a couple of days and bacteria might form on the permeate port. While the Caripur has bacteria-resistant components and tubing, it is recommended to, after a period of standing, run the water for about a minute. If the wait period has been longer then a couple of days, add chlorine to the port supplied with our unit to shock the system.
Caripur units are NOT mobile, and require a plumber to detach and up to 3 people to relocate the units to another location for installation.
Yes, we provide detailed information about the different components’ warranty within our quotations, and at the bottom of the website.
The Caripur™ is the passive/powered unit that can remove elements down to .02 microns (viruses, bacteria, cysts, etc.), producing microbiologically clean water at a rate of up to 20 gpm (76 lpm). The Caripur H2O™ “050” produces up to 10gpm, and the “010” produces up to 20gpm.
Capacity depends on the type of unit.
- Caripur 050 up to 600 gph [2271 l/h]
- Caripur “010” up to 1200 gph [4542 l/h]
- Caripur “020” up to 19000 gph [71,922 l/h]
The amount of water that can be treated depends mainly on the following issues:
1) Turbidity, which is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, only affects it insomuch that the unit might require more frequent purging in highly turbid water.
2) Concentration polarization which is A layer is formed near the surface of the membrane, whereby the solution immediately adjacent to the membrane surface becomes depleted in the permeating solute on the feed side of the membrane. This is corrected by backflushing, and in more extreme instances the use of our organic solution to break apart the polysaccharide structures
3) Power availability
Our pumps provide the appropriate pressure; however, it is approximately 2 bar.
Approximately 5 to 6 bar, depending on the unit and contamination.
No, this is however an option.
Backward flush is a reversed filtration process. Permeate is flushed through the system under pressure, floating the material and forcing it out.
No chemicals are required.
Our units are low pressure, so that assists in reducing the effect. In addition, we reduce concentration at the contact surface by reducing solids in the feed with the use of external filtration when necessary.
Reversible fouling is performed by a backwash; irreversible fouling is handled with our 100% organic cleaning solution, which breaks apart the polysaccharide structures that hold the particles on the membrane surface together.
Not, currently, however we have designs on the drawing board for both brackish and salt water.
The maximum turbidity is 28.
The Caripur is 99+% free of pathogens. The Caripur™ “P” and “I” units are 99.+% free of pathogens, and color, odor, flavor, a high percentage of heavy metals, and multivalent ions.
Yes, but the units will need to be configured for it.
Caripur™ cannot guarantee safe drinking water as such. We provide the technical equipment to treat contaminated water and remove 99.999% of contamination from raw water, ensuring we meet or exceed drinking water requirements int the United Sates.
Ultrafiltration is a type of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high-molecular-weight are retained in the so-called retentate, while water and low-molecular-weight solutes pass through the membrane in the permeate.
Nanofiltration (NF) is a pressure-driven membrane process for liquid-phase separations. NF has replaced reverse osmosis (RO) in many applications due to lower energy consumption and higher-flux-rate salts. The properties of NF membranes lie between those of non-porous RO membranes (where transport is governed by a solution-diffusion mechanism) and porous ultrafiltration membranes (where separation is usually assumed to be due to size exclusion and, in some cases, charge effects).
Granular activated carbon is commonly used for removing organic constituents and residual disinfectants in water supplies. This not only improves taste and minimizes health hazards; it protects other water treatment units such as reverse osmosis membranes and ion exchange resins from possible damage due to oxidation or organic fouling. Activated carbon is a favored water treatment technique because of its multifunctional nature and the fact that it adds nothing detrimental to the treated water.
Brackish water is either slightly salty or contaminated with dissolved solids and therefore is not drinkable for humans. Brackish water is metered with a total dissolved solids (TDS) level that ranges from 1,000 to approximately 15,000 TDS.
Total dissolved solids (TDS) comprise inorganic salts (principally calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulfates) and some small amounts of organic matter that are dissolved in water.
PPM (parts per million) is a measurement for water quality or salinity.
Gray water is gently used water from your bathroom sinks, showers, tubs, and washing machines. It is not water that has come into contact with feces, either from the toilet or from washing diapers. Gray water may contain traces of dirt, food, grease, hair, and certain household cleaning products.
The Caripur pump delivers up to 600 gph (2,271 l/h) of water.
We also provide pumps for larger volumes. Please contact us for further information.
Our standard tubing package includes 10 feet (3 meters) of hose. In case of deeper wells or boreholes, other pumping equipment is available.
The power consumption depends on the type of unit. Please see our factsheets.
Yes. However, an additional inverter can be delivered within the unit, if this is not already integrated.
Maintenance of the Caripur is performed through back-flushing the unit when the permeate flow has dropped 10% or more below its standard flow. Additionally, our organic cleaning solution can be used if back-flushing fails to return the flow back to the normal rate.
Yes, the maintenance outlined above can only be performed by approved technicians.
The Caripur is built to last for years. However, the life of a Caripur is dependent on regular and proper maintenance of the unit.
Our units are equipped with a pre-filtration system, which can be back-flushed. On occasion, cleaning by hand of the external gravel and plant matter filters is recommended.
From time to time, our 100% organic treatment of the membrane is recommended. For longer storage of the unit, our 100% organic treatment is necessary.
