FAQ: Frequently Asked Questions
What is reverse osmosis (RO)?
Reverse Osmosis, also known as Ultra-Filtration by the industry, represents state-of-the-art in water treatment technology. Reverse Osmosis was developed in the late 1950’s under U.S. Government funding, as a method of desalinating sea water. Today, reverse osmosis has earned its name as the most convenient and thorough method to filter water.

It is a process that uses a semi-permeable membrane to screen contaminants down to .0001 of a micron in size with a micro organism rejection rate of 99.95%. The rejection rate for inorganic contaminants such as harmful heavy metals and chemicals is 95-99%.

This membrane has the ability to remove and reject a wide spectrum of impurities and contaminants from your water using only water pressure.

Only purified water which has passed through the membrane gets collected and stored in an air tight sterilized, STAINLESS STEEL WATER TANK.

How does it work?

In short, reverse osmosis the process is in which water molecules are forced through a 0.0001 micron semi-permeable membrane by water pressure. It is this pressure that supplies the energy to force the water through the membrane, separating it from unwanted substances. The most amazing aspect reverse osmosis (RO) is that the substances left behind are automatically diverted to the waste drain so they don’t build up in the system as with conventional filtering devices. This is accomplished by using a part of the unprocessed water (feed water) to carry away the rejected substances to the drain, thus keeping the membrane clean. This is the reason RO membranes can last so long and perform like new with minimum maintenance even after years of operation.

How does RO water compare with bottled water?

Water purification using the reverse osmosis system gives our drinking water a good, clean, ultra fresh taste. Major bottling plants use water filtration systems which often leave the water tasting bland and distilled. Reverse osmosis can be installed in your home, office, factory almost anywhere you need it, and is always available. This means that you do not have to lug heavy bottles around. Instead, just open the tap for purified water!

How does RO differ from a water filter?

Water filtration passes ordinary tap water through a series of filters. These filters only separate particles of dirt and sediment from the water. Conversely, reverse osmosis employs a semi-permeable membrane that removes a wide spectrum of impurities and an extremely high percentage of dissolved contaminants-molecule by molecule – from raw tap water using existing water pressure to force water through the membrane.
What’s the difference between our 3-stage and other company’s 5-stage?
In order for us to explain the difference between a 3 and 5- stage reverse osmosis system, it’s important that you understand the meaning of the term “stages”. A “stage” simply means a filter used in the reverse osmosis process.

Conventional thinking would lead you to believe that more filters in a R.O. system would yield a proportionally better product. This is simply not true!

Many reverse osmosis companies will place an inline carbon filter after the water storage tank in a typical reverse osmosis system installation. The function of this filter is to eradicate any aftertaste leached from the inside of a storage tank. An aftertaste caused by leaching is a perfectly normal condition or byproduct of water store in a brand new tank. The carbon filter is a very effective medium in the elimination of taste caused by this condition.

Aqua Chill has long believed this additional stage is not only unnecessary but harmful to the environment, as the same effect can be realized by simply rinsing the holding tank prior to installation.

Many companies manufacturing 5-stage reverse osmosis systems place 2 granular carbon filters before the membrane in order to protect it from chlorine. Granular carbon filters, while effective in the elimination of chlorine, are not nearly as effective as solid carbon block filters used in the manufacture of the Aqua Chill reverse osmosis system. Granular carbon filters, unlike solid carbon filters can allow chlorine to pass through the system to the membrane, which leads to shortened membrane life.

Always environmentally conscious, Aqua Chill is constantly evaluating better options to prevent waste and increase the operating efficiencies of our family of products.

Why is my bill so high?
Your initial bill includes both first and last month’s rent. Subsequent invoices will reflect only your low monthly rate.
Why should I sign a multi year contract?
Many companies are reluctant to sign long term agreements and we understand completely! In most cases, companies who lease reverse osmosis drinking water systems have partnership agreements with 3rd party leasing companies. These companies typically trade the agreement for a 1-time cash payment to your provider.

As the decision maker for your company’s drinking water needs, you will want to give these types of agreements much scrutiny, as the moment this agreement is sold to the leasing company, your company is obligated to pay through the end of the term. This is true whether or not your provider has performed the maintenance on your system as agreed!

With Aqua Chill, the risk is entirely eliminated. As Aqua Chill finances its own equipment purchases, your company will always be dealing directly with Aqua Chill on both the rental and service of your system.

Aqua Chill has several different rental options from which to choose. Short term to longer term - the choice is yours. If your company is at ease with a longer term, be sure to ask you sales representative about special pricing options.

Is there a charge for service when I rent a drinking water system from Aqua Chill?
With Aqua Chill, there is never a charge for installations of new systems, relocation of existing systems and service or parts used in your system.
Why should I go with Aqua Chill instead of another water co?
Aqua Chill has three distinct advantages over our competition:
  1. Aqua Chill is the manufacturer of your reverse osmosis system - most companies in our industry simply purchase systems and/or components from several suppliers. If you were to examine the equipment in the accounts of our competitors you may see several different manufacturers reverse osmosis systems installed there. These companies typically purchase their product based on cost and not on performance. As a manufacturer of reverse osmosis products for over 25 years, Aqua Chill updates the reverse osmosis purification unit at least annually. If your Aqua Chill system was installed 10 years ago, it will always include the same updated operating parts as those systems installed today.

  2. Top of the line component used in the manufacture of your reverse osmosis system. Aqua Chill uses only the Filmtec, Thin Film Composite membranes manufactured by Dow Chemical. This Dow Chemical product us approved by both the FDA and USDA. Aqua Chill also uses only Solid Carbon Block pre-filters to eliminate any guesswork on the timing of your filter change.

  3. Great service protocol, all at no extra charge.

Aqua Chill’s preventative maintenance is performed every 6-8 months and consists of the following service elements:

  • Replace pre-filters every 6–8 months.
  • Replacement of Reverse Osmosis membrane at least every 3-years.
  • Reverse Osmosis tank is sanitized ever 12 months.
  • Tank re-pressurization every 12 months.
  • Cooler exterior cleaned every 6-8 months.
  • Heat exchanger is cleaned every 6-8 months.
  • Incoming water pressure to reverse osmosis system tested every 6-8 months.
  • Product and source water tested for TDS (total dissolved solids) every 6-8 months.

Many competing companies perform preventative maintenance only every 12-18 months.

  1. Free installation utilizing components that exceed industry standards.

Aqua Chill uses air gaps or check valves on all of our installations. An air gap or a check valve prevents water from a backed up drain flowing backwards into the reverse osmosis system. These measures protect the system from being contaminated with bacteria. Many companies do not install air gaps or check valves on their reverse osmosis systems, leaving them vulnerable to the formation of bacteria.

All of Aqua Chill’s installations are hard plumbed. Aqua Chill uses only easy adapters or tees when attaching to the cold water supply line. These connection methods conform to local plumbing codes and hence, are much less likely to leak. Many competing companies use piercing valves, which are notorious for causing leaks.

Aqua Chill installs the reverse osmosis system at the water source instead of inside your drinking water cooler. This type of installation is important for these reasons:

  • Water Pressure - If your chosen cooler location is not within 10 to 15 feet of a water source there may not be enough water pressure for a reverse osmosis system to function correctly. If you choose to locate your cooler greater than 15 feet from the water connection, both the quality and quantity of your drinking water may be negatively affected.

  • Surface area of the filtration media - Companies that put reverse osmosis systems inside their customer’s cooler may have to use miniaturized filter components to make them fit. While it might seem like a good idea to install the reverse osmosis system inside your cooler cabinet using miniaturized filter components, there is much less filtration media for the water to pass through leading to a greatly shortened filter life. Aqua Chill only uses full size commercial components in all systems it manufacturers.

  • Increased exposure for potential leaks – If you’re evaluating a reverse osmosis company planning to install the reverse osmosis system inside your cooler, you are exposing yourself to needless liability in the event a leak was to occur.   Most water lines in a typical commercial reverse osmosis system installation involve running a water line inside your walls and ceiling space.   If your reverse osmosis system is installed inside your cooler, your technician must run a pressurized line to and from the cooler. In the event of a leak, you have full city water pressure and the potential for major flood damage. Aqua Chill installs the reverse osmosis system at the water source and runs only the product line through the ceiling and wall to the cooler.  In the event of a leak, your reverse osmosis unit is only making a little over one gallon per hour (25gpd reverse osmosis system). This greatly minimizes your exposure to water damage caused from leaks.
Why go with reverse osmosis instead of bottles?
There are many reasons that the Aqua Chill product is superior to bottled water. The following points explain why businesses are switching to reverse osmosis in record numbers:
  • Less expensive.  All bottled water companies have seen their costs rise dramatically with the recent increases in fuel prices. These costs must be passed on to the consumer through cost increases in your cost per bottle and/or fuel charges. It should come as no surprise that the Aqua Chill Reverse Osmosis System installed in businesses costs much less to operate. Most businesses save at least 30% by switching to Aqua Chill.

  • More sanitary.  Bacteria inside most bottled water coolers are omnipresent. According to an article in Water Conditioning & Purification Magazine, October, 1997 edition, an article entitled Keep it clean: Bacteria and water cooler hygiene; cites the following: “Unlike POU (point of use) coolers and self-filling bottles, bottled water coolers are not closed systems. Your water may be absolutely pure when the bottle is sealed. But once the bottle is opened, that’s another story. Any numbers of workers handle each bottle, everyone adding his or her germs to its surface. Even with today’s advances in water cooler designs, those germs can migrate into the cooler. Without a no-spill protection device, such infection is a virtual certainty”

  • Reduce the risk of workplace injury.  Rising Worker Compensation costs are a major expense facing all corporations throughout the United States. With Aqua Chill’s bottle-less drinking water system you will reduce your exposure to Worker Compensation claims by eliminating trip hazards and back injuries due to lifting cumbersome bottles.

  • Made fresh, on demand.  Some bottled water companies will stockpile pallets of bottled water during their peak demand months. By the time you have your bottled water delivered to your business; it could be days or weeks old. With Aqua Chill, your water is made fresh one glass at a time.

  • Fixed monthly cost.  Most bottled water users have grown accustomed to the cyclical nature of their bottled water bill. Most businesses will notice a significant increase in the cost of their bottled water during the hot summer months, and then level off in the winter. With Aqua Chill, your monthly rate does not change regardless of the volume of water consumed. Summer or winter, same low monthly rate!
Why should I sign a multi year contract?
Most companies are reluctant to sign long term agreements and who could blame them! In most cases, companies who lease reverse osmosis drinking water systems have partnership agreements with 3rd party leasing companies. These companies in turn, trade the agreement for a 1-time cash payment to your provider.
