FAQ

Oxymatic is a water-disinfection system comprising a box carrying electrodes, which is fitted inside a pipe by-pass, also a control unit.
This system is based on an ecological approach to water-treatment, based on ABOT (Advanced Bipolar Oxidation Technology), which is a patent-protected treatment process. This technology is the outcome of more than 15 years’ research. It is used in water hydrolysis and copper ionisation to provide ecological water disinfection.

Oxymatic is intended primarily for swimming pools, but as it’s an extremely effective water-disinfection system, it can be used for other applications:

• Potable water, tap water or well water
• Treatment of the Legionella’s bacterium
• Irrigation and agriculture
• Cooling towers, etc.

Hydrolysis is the process whereby a water molecule separates out into different strains by passing an electric current through it.
The main reaction of the hydrolysis process is as follows:

2 H₂O  ——–>  OHˉ + H₃O

Hydroxyl ion (OHˉ) is a powerful disinfectant that will recombine in water in approximately 32 minutes if it does not come into contact with any organic matter, so that the water is neither corrosive nor harmful to health or living creatures, and can be drunk. By virtue of the technical features of this process, there will never be excessive hydroxyl that could be harmful to health or the environment.

Copper ionization is a process whereby a compact block of copper is broken up in a controlled manner by applying an electric current to it.

Pure copper ions are produced by this process (Cu⁺⁺) just as they occur in nature. A recommended concentration in a swimming pool is in the region of 0.5 mg/l (ppm). Such levels of copper will not affect the health since, according to the WHO (World Health Organization), water is potable with up to 2 mg/l copper.

No. The maximum hydroxyl-producing capacity of Oxymatic is determined by the relationship between the number of plates in the electrodes installed and the electric current applied. The level of those parameters never varies; the maximum power delivered cannot be increased, either intentionally or by accident. Nor is it possible to get an overdose through faulty installation or programming. Apart from the technical safety hard-wired into the design, no overdosing is possible with this clean hydrolysis process. This is because hydroxyl ion has a short half-life providing it does not come into contact with organic matter, bacteria or viruses. This characteristic means the water is non-corrosive and non-harmful to health, even if drunk.

Regarding copper, what Oxymatic produces is ion Cu⁺⁺, pure copper, which itself occurs in nature. The human body requires this type of metal (1000 μg daily is the total daily amount recommended by the EU), the same as for iron, potassium, vitamins, etc.

Oxymatic is prepared so as to maintain a constant concentration of 0.5 mg/l copper in the water. This level is not harmful to health, nor to any material. The standard for potable water states that water is potable and can be drunk if its copper content is below 2 mg/l.

En cuanto al cobre, lo que el Oxymatic produce es el ion Cu⁺⁺ , cobre puro, que es el mismo que está en la naturaleza. El cuerpo humano necesita este tipo de metal ( 1000 µg diarios es el 100 % del CRD Cantidad diaria Recomendada por la UE), al igual que el hierro, potasio, vitaminas, etc…

Oxymatic está preparado para mantener una concentración constante de 0,5 mg/l de cobre en el agua. Este valor no es perjudicial para la salud ni para ningún material, la normativa de aguas potables dice que un agua es potable y se puede beber si el cobre está por debajo de 2 mg/l

The same flow is able to pass through an electrode-carrying box as can pass through a 75 mm PVC pipe. The flow that can pass through a pipe will depend on the water flow’s speed and pressure. A key feature of our system is that by equalising speed, pressure and the flow that passes through the box, the production of hydroxyl will not be affected.

No; there is no technical limit with regard to the volume or flow that can be treated. It can treat a volume of approximately 175 m3 for a pool per day using one box.
We can expand the system by deploying as many boxes as necessary, and thus treat any volume of water. The hydroxyl produced by each box will accumulate in order to disinfect the entire volume of the pool.

The box is designed to withstand pressure of 20 bar. There can never be any problem, given that PVC cannot tolerate more than 16 bar.

Alkalinity is an essential parameter that has to be set when starting up a swimming-pool. The Oxymatic system will not affect alkalinity; however, low alkalinity can cause problems in adjusting the pH, greenish water pipe, and compromise the effectiveness of the purification system.

An appropriate setting is between 100 and 175 mg/l. It is often necessary to increase it. To do this, use an alkalinity booster (bicarbonate of soda or carbonate). Once set, it is not usual to amend it greatly subsequently.

Rapid-impact treatment should be administered in order to ensure proper operation of the system, even though we use fresh mains or well water, and all appears to be in order. Yet we cannot know whether there might be algae, spores, bacteria, etc. In view of this uncertainty, it’s best to do it.

You can use a special anti-algae based on Cationic Polymer for pools with treatment without chlorine. DO NOT USE ANTI-ALGAE TREATMENTS THAT CONTAIN COPPER SULPHATE.
Procedure: Programmed pump time: 10-12 hours / Set copper to the minimum: 0.3 mg/l. Initial treatment: pour 1 litre anti-algae into the vessel at dusk for each 50 m3 volume of water and continue recirculation until next day the first day. For maintenance, pour ½ litre a week, using the same routine.

Yes: however, you must be sure NOT TO USE CAPSULES THAT CONTAIN COPPER SULPHATE.
Procedure: Programmed pump time: 10-12 hours / Set copper to 0.3-0.4 mg/l. Place one capsule in the skimmer for every 50 m3 volume, once a week.

Yes: To do this, we can fit an automatic dose-measurer to inject hydrogen peroxide (liquid oxygen), controlled automatically by Oxymatic:
Procedure: You must change the program, eliminate copper, and programme the minutes to the time of day at which you wish the pump to release a dose, so as to hold the residual concentration at around 5-10 mg/l peroxide in the water.

Yes: fit an automatic dose-measurer to inject liquid sodium hypochlorite, controlled automatically by Oxymatic:

Procedure: There are two ways of doing this.

Dosing by time: Remove the copper and programme the minutes to the time of day at which you wish the pump to release a dose, so as to hold the residual concentration at around 0.3-0.5 mg/l chlorine. The minutes can be adjusted in accordance with measurements taken at the vessel.
Dosing by using Redox: Instal the dosing pump and redox probe, activate the cannel and take the desired set-point. Change that set-point in accordance with the measurements taken in the vessel until the system is set correctly.

In the case of public swimming-baths that need residual dosing to satisfy official requirements, we use this system with Redox.

– Check the existing recirculation system, type of water, the age of the water and filter: the efficiency of any disinfection system depends on these factors.
– Temperature that the water may reach in the summer: in order to calculate Oxymatic’s hours of operation.
– Total salinity: to ascertain and adjust the equipment voltage.
– Alkalinity: Check the pH and eliminate any algae or murkiness.
– Copper: Program the system and avoid any overdosing.
– pH: must always be properly adjusted.

For the SMART PRO 400 models, which provide two electrode-carrying boxes.

What needs to be kept firmly in mind is that the recirculation flow must not decrease.
It is essential to consider the diameter of the recirculation pipe in relation to the time required for complete recirculation. We must instal the number of chambers required in order that all pool-water will pass through the chambers, and so that the circulation flow shall not fall below <10%, as a by-pass and in parallel.

For example, we recommend using PVC pipes:

Pipe ≤ 75 mm 1 chamber or 2, in line
Pipe 90 to 140 mm minimum 2 chambers in parallel
Pipe 140 ≤ 225 mm minimum 3 chambers in parallel
Pipe 225 ≤ 300 mm minimum 4 chambers in parallel

Use rapid-impact granulated chlorine for chlorination (we recommend dichloro or trichloro).

– Pour in using a sufficient amount in accordance with the instructions on the tin, to raise the chlorine to 10 mg/l (ppm). As an indication, fill 2-3 kg dichloro for every 50 m3 water in practice.
– With recirculation running, pour half into the skimmers and distribute the remainder in the vessel. It is not necessary to dilute it.
– Leave filtration in place during complete replacement of the water. This will depend on the flow from the pump, but the normal time is 4-5 hours.
– Shut off the pump and wait 8 hours (till next day).
– If there are algae, rub the walls and base down with a brush.
– Take the base cleaner and clear any residues of algae and dirt out of the pool (so that it does not pass through the filter, nor run back into the pool).
– Carry out washing of the filter and rinse.
– Start up the system as normal. Once the chlorine concentration falls below 2 mg/l (ppm) you can use the pool. If you use dichloro, this will be within approximately 48 hours or, with trichloro, from 2 to 3 days.

We recommend that copper in the pool should be held at around 0.5 mg/l. To achieve this, you should check the program and verify water’s copper content when starting up, and for the first few weeks.

Follow the steps below to do this.

– Measure the copper in the water when full. If there is copper, we need to take this into account when carrying out programming.
– The equipment leaves the factory with nominal programming for pool sizes 80, 125, 175 and 400 m3. If your pool is a different size, you need to amend the program using the following table:

These times are for guidance. They may need to be increased or decreased, depending on the measurements obtained.
Consult the manual to amend the program, depending on the model.

An excess of copper: with our technology, this can only come about through faulty installation, programming or control. If we find there are yellowy-green or bluish stains at the joints of the gresite or in the Liner, there could be an excess of copper in the water – or there has been an increase in pH and temperature, which was not checked.

Solution:

1.- The first thing we need to do is measure the copper in the water several times, and at different locations. If there is copper, we need to detect and correct the problem. This could be due to:
– Faulty installation: Cables changed (OXY – ION)
– Incorrect programming: Too many minutes each day
2.- Turn off the copper channel by programming it (refer to instruction manual)
3.- Reduce the copper in the pool. This can be done in two ways:
– Renovate part of the pool, wash out, etc. Check and carry out daily measurements. The copper will gradually disappear.
– Use a metal flocculant or special copper remover.

A level of copper up to 2 ppm is not harmful to health, but can cause stains.

In order that your Oxymatic system will function effectively, we need to remember that the daily hours of operation are directly dependent on water temperature. The higher the temperature, the greater the number of hours of operation required.

Hours of operation will normally be as follows:

• Water 15º-20ºC = 4 hours continuously – 10.00 to 14.00
• Water 20ºC = 6-8 hours continuously – 10.00 to 17.00
• Water 25ºC = 8-10 hours continuously – 08.00 to 18.00
• Water 28ºC = 10-12 hours continuously – 08.00 to 20.00
• Water 29ºC = 12-14 hours continuously – 06.00 to 20.00
• Water >30ºC = consult beforehand.

From 29°C or more, it is possible you may occasionally need to use a disinfectant (anti-algae, hydrogen peroxide, multiple-action capsules, chlorine, etc). “Consult the manufacturers on a case-by-case basis”.

This is caused by a lack of disinfection, which can come about through various causes.

Identify the problem, carry out rapid-impact chlorination and remedy the problem. To do this we need to check the equipment, electrodes, voltage, etc. to verify that everything is in order.

If we find that all equipment is in order, there could be one or more causes:

– Hours of treatment are not commensurate with the water temperature. Hours of treatment need to be continuous.
– Alkalinity is too low: the correct parameters are between 80 and 175 mg/l.
– Poor pump recirculation and ‘dead’ areas.
– Old and/or poorly-blended water.

• Press the alarm button to turn off the buzzer.When the alarm is set off, the system is shut down and stops operating. There are only two reasons why the alarm might sound:
  • Failure of the titanium electrodes/OXY system (production of Hydroxyl)
  • Failure of the copper electrodes/ION system (production of Copper)

  A red LED indicates which channel it is. To resolve the problem, you should proceed in the same way, irrespective of the channel:
  Check:

  • Lack of salt (low water conductivity)
  • Electric cables are failing to make proper contact at the electrodes
  • A green internal cable plug has come adrift
  • An internal cable has come out of its plugElectrodes are wasted away or degraded

To do this, everything is the same as for the pH reducer, except that we have to change the set-points and place them in the pH booster flask.
The set-points we need to take:

0% = 7.0
100% = 6.8

Once it reaches 7.0, the pump will shut down and release a dose below.

The hydroxyl ion prevents corrosion of pipes, metal materials, stone, marble etc… and is totally harmful to health, hair, clothing, metals, etc… … and do not generate oxidizing vapors for covers

Yes, and one of the benefits is that it does not corrode the metal parts, does not generate toxic vapors and with the OXYMATIC system, indoor pools will smell good.

Yes, although the electrodes are self-cleaning, when the water is very hard scale problems can appear, but much less than with any other system, since the ABOT technology has a certain descaling power in the water.

Yes, OXYMATIC disinfects any type of water, including sea water.
