Crystal Quest Thunder 4000C / 4000CP Reverse Osmosis System, Post tank Ultra filtration - UV Sterilizer - GAC cartridge

Utilizes Ultraviolet Water Sterilizer system, making it the most dynamic filtration processes you can find!! 

The CRYSTAL QUEST® Reverse Osmosis Ultrafiltration systems produce up to 100  gallons of top quality water per day and remove up to 99.9% of undesirable contaminants and filter particles as small as 1/1000 of a micron by forcing untreated water through a semi-permeable membrane. Pressure forces the water to flow in the reverse direction to the direction of flow in natural osmosis.

CRYSTAL QUEST® Reverse Osmosis Ultrafiltration systems have compact designs that can easily fit beneath the kitchen sink. Supplied with a complete installation kit.

-  Installation Hardware For No Hassle Installing

Water travels through 14 stages of filtration

• In stage 1, Water travels through a 5 micron solid carbon cartridge for removing volatile organic carbon compounds (VOC's), insecticides, pesticides and industrial solvents and traps particles larger than 5 micron including sediment, silt, sand and dirt. It also helps to extend the life of the system.

• In stage 2, water passes through a 0.2 micron Ultrafiltration (UF) membrane. Ultrafiltration (UF) is an important purification technology used for the production of high-purity water. UF is effective for the removal of colloids, proteins, bacteria, viruses, parasites, protozoa and pyrogens (e.g., gram-negative bacterial endotoxins), other organic molecules larger than 0.2 micron, and most other water contaminants known today. 

• In stage 3, Water flows through pre one - micron filter pads (1 micron equals 1/25,000th of an inch), which removes suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved matter.

• In stage 4, water passes through granulated activated carbon (GAC). GAC is universally recognized and widely used as an effective adsorbent for a wide variety of organic contaminants, such as chlorine (99.9%), chemicals linked to cancer (THM's, benzene) pesticides, herbicides, insecticides, volatile organic compounds (VOC's), PCB's, MTBE's and hundreds of other chemical contaminants that may be present in water, bad taste, and odors from your drinking water.

• In stage 5, Water flows through the ion exchange resin, reducing heavy metals such as lead, copper, aluminum, and water hardness.

• In stages 6 and 7, water flows through 2 beds of Redox (Oxidation/reduction process) media made of a special high-purity alloy blend of two dissimilar metals - copper and zinc. Representing a new and unique way of water processing medium which by its natural process of electrochemical oxidation/reduction and adsorption action reduces and/or removes many unwanted contaminants from water. It is a major advancement in water treatment technology that works on the electro-chemical and spontaneous-oxidation-reduction (Eagle Redox Alloy®) principles. Chlorine is instantaneously and almost inexhaustibly oxidized. Iron and hydrogen sulfide are oxidized into insoluble matter and attach to the surface of the media. Heavy metals such as lead, mercury, copper, nickel, chromium, cadmium, aluminum, and other dissolved metals are removed from the water by the natural process of electrochemical process. They are attracted to the surface of the media, much like a magnet. The media inhibits bacterial growth throughout the entire unit.

• In stage 8, Water flows through another one-micron filtration pad for further reduction of undesirable particles. The end result is a great reduction or elimination of a wide variety of contaminants.

• In stage 9, Water passes through a CRYSTAL QUEST® reverse osmosis membrane, which removes and filters particles as small as 1/10,000 of a micron as most inorganic chemicals (such as salts, metals, minerals) most microorganisms including cryptosporidium and giardia, and most inorganic contaminants. 

• In stage 10 and 12, Water flows through another one - micron filter pads(1 micron equals 1/25,000th of an inch), which removes suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved matter.

• In stage 11, water passes through granulated activated carbon (GAC).

• In stage 13, water passes through an Ultraviolet Water Sterilizer System manufactured with axial flow reactors in 304 stainless steel. The hard glass germicidal lamps provide an economical way of treating water requiring a 99.99% reduction of bacteria and virus and protozoa. This process is accomplished without adding any harmful chemicals to your drinking water. CRYSTAL QUEST® Ultraviolet Water Sterilizer System is the most ecological way of treating your water.

• In stage 14, water travels through a 0.2 micron Ultrafiltration (UF) membrane. Ultrafiltration. UF is effective for the removal of colloids, proteins, bacteria, viruses, parasites, protozoa and pyrogens (e.g., gram-negative bacterial endotoxins), other organic molecules larger than .01 micron, and most other water contaminants known today.

What is Ultrafiltration?

Ultrafiltration (UF) is a membrane filtration process similar to Reverse Osmosis, using hydrostatic pressure to force water through a semi-permeable membrane. The pore size of the ultrafiltration membrane is usually 103 - 106 Daltons. Ultrafiltration (UF) is a pressure-driven barrier to suspended solids, bacteria, viruses, endotoxins and other pathogens to produce water with very high purity and low silt density. Ultrafiltration (UF) is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semi permeable membrane. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. Ultrafiltration is not fundamentally different from reverse osmosis, microfiltration or nanofiltration, except in terms of the size of the molecules it retains.

Healthy drinking water for your whole family

A membrane or, more properly, a semi permeable membrane, is a thin layer of material capable of separating substances when a driving force is applied across the membrane. Once considered a viable technology only for desalination, membrane processes are increasingly employed for removal of bacteria and other microorganisms, particulate material, and natural organic material, which can impart color, tastes, and odors to the water and react with disinfectants to form disinfection byproducts (DBP). As advancements are made in membrane production and module design, capital and operating costs continue to decline. The pressure-driven membrane processes discussed in this fact sheet are microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO).

The primary advantages of low-pressure UF membrane processes compared with conventional clarification and disinfection (post chlorination) processes are:

• No need for chemicals (coagulants, flocculates, disinfectants, pH adjustment); 
• Size-exclusion filtration as opposed to media depth filtration; 
• Good and constant quality of the treated water in terms of particle and microbial removal; 
• Process and plant compactness; and 
• Simple automation.

Ultrafiltration (UF) is used to remove essentially all colloidal particles (0.01 to 1.0 microns) from water and some of the largest dissolved contaminants. The pore size in a UF membrane is mainly responsible for determining the type and size of contaminants removed. In general, membrane pores range in size from 0.005 to 0.1 micron. UF membrane manufacturers classify each UF product as having a specific molecular weight cutoff (MWC), which is a rough measurement of the size of contaminants removed by a given UF membrane. A 100,000 MWC UF membrane means that when water containing a given standard compound with a molecular weight of around 100,000 daltons is fed to the UF unit, nearly all of the compound will not pass through the membrane.

Substances with a molecular weight of 100,000 daltons have a size of about 0.05 microns to about 0.08 microns in diameter. UF membranes are used where essentially all colloidal particles (including most pathogenic organisms) must be removed, but most of the dissolved solids may pass through the membrane without causing problems downstream or in the finished water. UF will remove most turbidity from water.

When considering installation, if current under sink plumbing is hard copper tubing the saddle valve would be used; for flex tubing the T-valve would be required. While ordering a prompt will require that an installation valve be specified in order to progress through the order entry screen.
