The problem

ACP may be used as a chlorine free product in private pools, or it may be used in combination with chlorine in private or public pools to reduce chlorine demand. The production of some chlorine by-products such as THM`s is accelerated by Ultra Violet UV light, direct sunlight or even with light shining through the windows of an indoor pool. ACP shields the water and chlorine from short wavelength UV light, so the pools use much less chlorine and generate fewer chlorine reaction products.

What is ACP?

ACP  is a blend of poly-silicates and transition metal oxide nano-particles.  The poly-silicates increase the zeta potential and drag +ve charged organics out of solution. The poly-silicate lays down a molecular thick layer high zeta potential skin on tiles and pipes to give a non slip surface that helps prevent bacteria growing. Any remaining ACP in solution, when it returns to the plant room will react with APF active polyfloc to form an alumina-silicate floc that drops out of solution on top of the filter bed. The floc includes both +ve and –ve charged pollutants that have been coagulated and flocculated from the water.  The floc is large, stable and heavy so ACP helps to improve the performance of filters that are under-sized or are not running at the correct water flow.  The alumina-silicate formed between ACP and APF exhibits ion exchange properties and will remove ammonium from solution to help prevent inorganic chloramines. The nano particle component of ACP is catalysed by the ZPMr unit, or any UV light source.  UV wavelength photons are absorbed by ACP which then kicks out an electron to increases the redox potential of the water and the ability of the water to disinfect, but no chemicals are consumed in the process.

Why use ACP?

Sunlight or UV light in the presence of chlorine, ammonium and organic matter will cause photo-oxidation.  Chlorine consumption will increase, and more toxic volatile lipid soluble chlorine by-products are formed, combined chlorine levels may drop especially when medium pressure UVc irradiation is used, but the chloramines are replaced by chemicals such as cyanogen chloride and THM’s  that are much more dangerous. ACP absorbs ultra violet light and protects the chlorine from photo-oxidation, so less chlorine is used. Atmospheric conditions improve, stress corrosion cracking of the building and ventilation systems is reduced and there will be a return in expenditure out of revenue savings.

Dryden Aqua is perhaps the only marine biological company working in pool water treatment and through an understanding of chemistry, biology and nature, we have an insight that has allowed us to develop ACP for the protection of dolphins in chlorinated systems.  We do not advocate that you stop using chlorine, but ACP as part of an integrated water treatment approach will reduce your chlorine demand by up to 95%, and may eventually eliminate the need for chlorine.

How to use

• ACP should be dosed into the water after the filters
• Best injected before a ZPM mixer (Zeta Potential Mixer) 
• The application rate is 0.5 to 1.0ml per 1 cubic metre of water per hour pumped to the filters.  Example; if water flow is 80 cubm/hr to the sand or AFM® filters, the APF application rate is 80ml per hour. Dosing is only required to compensate for chemical lost in back-washing and water exchange.
• May be hand dosed once a week at a level of 10ml per cubic metre of water in the pool. For example, 80 cubm pool will need  800ml to be added once a week.

Information

• ZPM = Zeta Potential Mixer, APF works because it drops the zeta potential of the water, our ZPM catalyzes the performance of the APF
• AFM® (Active Filter Media) dramatically improves the performance of sand filters because it has a negative zeta potential.
• Dosing pumps available from Dryden Aqua.

• ACP is supplied in 25 kg drums as a liquid ready to use.
