Frequently Asked Questions
1. What is the warranty on Aqualtra's systems?
Aqualtra has a number of product lines and each of the product lines has several products that consist of different systems. These systems have a warranty ranging from 1 year to 10 years depending on the make, configuration and model of the products. Please contact Customer Service (972-971-9755) for detailed warranty information as it relates to specific products.
2. You claim that Aqualtra’s water treatment equipment produces water that complies with Certified Drinking Water Quality Standards, such as U.S. EPA Primary, World Health Organization (WHO) Guidelines, Official Mexican Norm, NOM-127-SSA1-1994, Colombian Water Purity Norms, Article 7, Peruvian Regulations, Canadian Guidelines, EU and other international regulatory entities. How about the water storage, piping and water dispensing of your AquaMobile products?
All material and construction design implemented on the AquaMobile models is food grade compliant. In order to ensure sustained highest level of drinking water quality by preventing oxidation or iron corrosion of the water storage, piping and water dispensing, all is made out of stainless steel material that is polished, welds and threads are of a food grade. All weld finish matches the material finish. Discoloration is removed from welds, cleaned and de-burred of all weld slag and splatter. All fabrication is done in conformance with ASME Standards. Also, all tanks, piping and dispensing are hydrostatically tested in conformance with ASME standards and is certified to be leak-proof. We adopt the strictest and highest workmanship criteria in our production operations.
3. We care about our citizens and want to be prepared for an emergency situation, but being a small municipality we don’t have the approved funds ready to purchase Aqualtra’s mobile water treatment unit. What options do we have for financing our purchase?
We have made an arrangement with a leasing company that offers attractive short or long term leasing options.
4. You packed a lot of stuff into one trailer. When something would break, it is going to be a nightmare to get to it out and to replace it.
We agree that we optimized the available space to the maximum. At the same time, we took this issue into consideration and designed the side walls of the trailer such that with pressing a button on the remote control panel, either side hydraulically swings open upward up to 180 degrees in its entirety and offers an easy access to the equipment installed anywhere through the length of the truck or trailer.
5. How many gallons/liters of drinking water per person/day are required in the U.S.?
On average a standard household uses 50 gallons/190 liters per day. Emergency situations 13 gallons/50 liters, but it can be cut in half. Hospitals require 65 gallons/250 liters per bed. Hotels use 80 gallons/300 liters per guest/day.
6. How effective is Reverse Osmosis technology? There seems to be a high sea water intake and considerably less drinking water is produced.
Reverse Osmosis is a proven technology and consists of sending seawater under high
pressure through a Reverse Osmosis membrane. This membrane is what is called a semi-permeable membrane. It is characterized by being selective so as seawater is pushed through the membrane, it will allow only pure water to pass through but not the salts present in the seawater. The salt will therefore be rejected and it will constitute the reject stream. As a result approximately 70 percent of the water sent to the Reverse Osmosis system will be pure water that has passed through the semi-permeable membrane. The remaining 30 percent is the salt with water that was rejected by the membrane.
7. We are building a “nice and healthy” beach for our guests, but when I saw the main picture in the solar powered Aqua Salt data sheet, I am worried what happens to water that is rejected by the unit? Is it possible that this water may be directed by the waves onto the beach polluting the area where families are swimming?
The reject stream that constitutes approximately 30 percent of the initial seawater to be treated is sent back to the sea. It is harmless since the salt in the reject stream has the exact composition of the salt in the seawater except that in the reject stream, its concentration is 3.3 times that of the salt in the seawater. Even at this concentration, 0.3 cubic meters per hour of reject salty stream is very insignificant and will be diluted very quickly by the vast volume of the seawater in the beach at a volume of Tens of Thousands of cubic meters (it is like putting a drop of water in a large bucket).
8. Since you sell your products internationally, do you also have a presence in other countries to service your equipment?
Aqualtra has been using a competent and responsive network of companies worldwide. Our primary relationship is with G-servis, s.r.o., company in Prague, Czech Republic, which has been in the water treatment business for over 20 years and has agreements with established representatives and distributors around the globe.
9. Can any of your products also treat and convert waste water into drinking water?
Aqualtra’s equipment treats raw water from ponds, lakes, rivers, wells, brackish and sea sources to potable water for human consumption. Aqualtra is not in the reclaimed water treatment waste business, nor in the effluent purification waste water processing business.
10. Would not treated water in your mobile equipment freeze in Northern parts of the country?
As an option, any of the three models AquaMobile 1000, AquaMobile 3000 and AquaMobile 6000 systems, intended to be deployed in frost belt regions, are winterized by having all water pipes wrapped in insulating sleeves, and the water treatment equipment inside the vehicle is protected with a special insulating material. This ensures that the systems would remain operational even under harsh cold temperature conditions.
11. You have a detailed data about your products on your web pages. But in a nutshell, I want to know what the application difference between AquaAlpha and AquaOxy models is?
The use of the AquaAlpha coagulation-flocculation system is recommended for use under conditions where the water to be treated has high turbidity. Low turbidity water conditions can be handled by the AquaOxy ultrafiltration system. However, highly turbid water is not desirable for ultrafiltration and the turbidity would need to be effectively removed before water reaches the ultrafilter. Otherwise rapid fouling of the ultrafiltration membrane may occur.
The AquaAlpha coagulation-flocculation system can, however, remove certain salts and heavy metals, as well as cationic minerals such as iron, manganese, magnesium, calcium, nitrites and sulfates.
Whereas the AquaOxy ultrafiltration system can be effective in removing large organic molecules, colloids, bacteria and certain viruses, smaller molecules and salts cannot be effectively removed using this system.
12. I am interested to know how much maintenance it takes to run your AquaOxy (ultra-filtration) water treatment unit.
The AquaOxy is a low maintenance system. If we assume 24/7 continuous operation, you would need every 3 days to perform 1 hour backwash of the sand filter and to clean the bag filters. Also, once a month you should plan to allocate 3 hours for the ultra-filtration membrane regeneration. These approximations are valid for stationary applications.
For the AquaMobile three models:
| BACKWASH | Days* | MEMBRANE REGENERATION | MONTHS |
|---|---|---|---|
| AquqaMobile 1000 | 18 | AquqaMobile 1000 | 6 |
| AquqaMobile 3000 | 11 | AquqaMobile 3000 | 3½ |
| AquqaMobile 6000 | 4 | AquqaMobile 6000 | 1½ |
*The above data represent averages based on two round trips per day. The frequency of maintenance may vary and it is predicated upon a concentration level of pollutants in the raw water.
Aqualtra can perform for you the backwash and also the membrane regeneration services.
13. Does your equipment treat wastewater?
• Aqualtra’s equipment treats raw water to potable water for human consumption.
• Aqualtra is not in the reclaimed water treatment of waste business.
• Aqualtra is not in the effluent purification wastewater processing.
