Frequentily Asked Questions

Home > Resource > FAQ

Product technology Asking before Sale

What is TDS?

TDS stands for total dissolved solids and represents the total concentration of dissolved substances in water.

What is the power consumption?

It depends on all pumps used for the equipment (different capacity use different pumps.)

How do I know what’s in my water?

If you receive water from a municipal water supplier, then you can review your local “Consumer Confidence Report” (CRC) to learn what is in your water. Each year, public water suppliers are required to provided a CRC. If you are on a private well, you can send sample of the water to a certified laboratory to do water analysis.

Which type of water treatment product should I purchase?

Once you know what is in your water, then you can better determine what you want to remove. This is accomplished with your water analysis. Next investigate and learn about what type of systems are available that address your specific needs. There are a number of resources that you can use to make a good buying decision.

My water taste bad? What may be the cause and how to improve?

If you want to treat the water to drinking and cooking water, a reverse osmosis system is a great option. Reverse Osmosis can remove dissolved solids, organic, lead, iron, fluoride, nitrates and dozens of other contaminants. In addition, an RO system can greatly improve the taste and the quality of your water by removing chlorine and other offensive tastes.

Once you have identified what is causing the taste problem you can then research what type of water treatment equipment is designed to address your specific needs.

What pre filters do RO system need ?

Pre filters as an important complement to the water treatment systems, it is designed to improve the water quality, especially to guarantee the RO and UF membrane’s service life and finally protect the whole water treatment equipment. The common pre filters are sand filter, activated carbon filter, manganese sand filter and softener.

Why drinking water need softener?

Hardness in water is caused by the presence of calcium and magnesium. High levels of these compounds cause scale build-up in water pipes and hot water heaters. Hard water also produces a soap scum and consumes more soap when bathing and doing laundry.

my water is lake water, a lot of yellow mud, I want to deal with water as a swimming pool, what equipment should I use?

For recycle water for swimming , only need sand filter + carbon filter + micron filter + UF system .

There is chlorine in my water. Is chlorine bad for me?

Chlorine in itself does not appear to be a problem other than the aesthetic concerns of undesirable taste and odor it creates. There has been a lot of research on the effects of chlorine with evidence showing that the biggest concern being its reaction with natural organic materials like leaves and humus forming disinfection by-products, which are considered carcinogens. Installing a point of use water treatment system that incorporates the use of carbon filtration can be very effective in correcting this problem.

How can bacteria be removed from water?

Bacteria and other microorganisms are removed from water through disinfection. This means that certain substances are added to kill the bacteria, these are called biocides. Sometimes disinfection can also be done with UV-light.

tap water has the taste of bleaching powder, what equipment to remove?

Use the carbon filter to remove bad smell of the water ;

Will the machine remove the salt?

UF system do not change the sanity of the water. RO system salt rejection rate is 96%. For example, if your water source is 1000ppm, then the output is 40ppm.

My water source is well water and hardness high. It is use for agricultural irrigation.

If you only need to remove the water harness, then softener is recommended. But if you need to reduce the sanity of the water, RO system is recommended.

Do UF system have waster water?

Yes, but the recovery rate of UF system is above 90%. It is just a little waste of the water.

Do you need a water softener?

If you find the equipment covered with dirt, and the water quality, taste or color changes, it may be hard water. In this case, you will need a soft water system to solve these problems. The use of the water-softening system is followed by an extension of the life of the equipment, thereby reducing the budgeted expenditure.

What water filtration system do you need?

We need to check what the raw water is? In general, most of the water is groundwater, surface water

Or city water. Generally there are impurities in the water such as (sand, suspended solids, particles, phosphorus, metals) , all need to use multi-media filter to remove.

The most popular is a sand filter, which removes particles and sediment.

If the raw water contains high iron, we should consider the use of Manganese filtration remove

How to remove odor from water?

Carbon filter can remove odor and bad taste.

How to remove bacteria from water?

Firstly, can use RO system to remove bacteria.

The RO membranes allow the water pass through, and separate and remove solid, organic, progeny, sub micron colloidal matter, color nitrate and bacteria from water.

2nd can use UV STERILIZATION

The use of UV sterilizers is cost-effective, fast, safe, chemical-free and easy to use. Agua RO UV sterilizer is of low pressure type and is the best sterilizing method for producing it for sterilization

Product technology Asking after Sale

Why I need to use water pump for the RO system?

The required inlet pressure of the RO system is 1-3 bar. If you use raw water tank, there is no pressure of the water tank. So raw water pump is needed for the RO system.

Do RO have waste water?

Yes. The RO membrane lets only water molecules pass through directing it to the units storage tank, the impurities that are separated from the water molecules are forced down the drain.

What is the percentage of pure water and waste water?

It depends on the machine capacity. Normally, it is 30%-65%. The capacity bigger, recovery water higher.

Do temperature have any effect on the pure water flow of the RO system?

Yes. The higher the temperature, the more the pure water.

What is function for micron filter?

A bag filter and security filter are added to the membrane to reduce the SDI value and protect the equipment.

What is changed in this machine after usage and after how long?

We have consumable list. We will let you what is going to replace and their replace time.

How will we know when to change the activated carbon filter?

1.the most convenient method: look at the pressure difference of the pressure gauge on the side of the tank; (after back washing)

2.You can use the Residual chlorine reagent to test to product water Chlorine content.

If the water color changed, then need to replace new activated carbon.

3.Just do a simple small test:

Take a part of the activated carbon in the activated carbon filter tank, and then take a part of the new activated carbon into the water to observe whether there are a lot of small bubbles in the water.

If the used activated carbon produces less bubbles than the new activated carbon, the activated carbon is indicated.

The saturation is full and needs to be replaced.

Manual type and automatic type differences (RO system with pretreatment).

Main difference is the Control Valve of pretreatment.

When run – backwashing – washing, the manual type RO system need manual operation,

The automatical RO system can set the time through the valve to time operation – backwashing – washing

How do you test the quality of treated/demineralized water?

The conductivity meter will show the treated water value, according the showed value, you can judge the water quality.

About life of machine ?

There is no problem when the machine is running for more than 15 years (running indoors).

But the machine has consumables which are need replace in time according to the water quality.

The regeneration of softener is done by time or by consumption?

the regeneration can done by time and also by flow volume, just need you confirmed with us which one do you need.

Amount in liters of soft water produced by each column before regeneration.

Use the flow volume type to calculate .

How long do softener need to do regeneration? And how long it last?

The regeneration time of the softener is 1 week. And each time it needs 1 hour. We will send you the valve manual for your reference.

How often cleaning the membrane ?

1,when SDI<3, chemical cleaning(cip) frequency every year 4 times ;

2,when SDI=5, chemical cleaning (CIP ) Frequency every year 8times ;

3,every chemical cleaning ( CIP ) also depending on the at site system detail ;

How to reduce the energy consumption of the membrane system?

To use the low-energy membrane elements, but it should be noted that their salt rejection is slightly lower than standard membrane elements.

What is the % efficiency of the RO membranes?

RO membranes desalination efficiency is 96%-99%.

What is the expected frequency of replacing the filter media and the RO membranes? (About life of filter and accessories for changing ?)

Quartz sand : 2-3years       ( depending on the raw water quality )

Coco nut carbon idion:1-2years ( depending on the raw water quality )

Resin : 1-2years            ( depending on the raw water quality)

RO Membrane : 18-24 months ( depending on the raw water quality)

When to use ion exchange softeners or antiscalant dosing?

For water softener and dosing system how to choose, need to check the raw water quality report of calcium magnesium ion hardness content, if is below 800 ppm can consider using water softener, if higher than 1000 ppm need to use dosing system.

How long does the system need to be cleaning(washing) by chemical ?

Need to check 3 things as below :

1,when the design capacity reduced 10%-15% ;

2,when the Desalination reduce 10%-15%;
