 | After the addition of APF or NoPhos the water should be passed through a ZPM, to mix the chemicals and cavitate the water. Thorough mixing can have a tremendous effect on the performance of the coagulant, indeed it can double the performance. Cavitation also kills crypto oocysts and helps sterilise the water. This will in turn improve the performance of the filter and reduce the amount of chemicals required. A ZPM also be used after the addition of carbon dioxide when used for pH correction. |

The primary function of ACP is to protect chlorine from photo reduction by sunlight and UVc irradiation and reduce the formation of cyanide. When ACP is used in conjunction with Dryden Aqua systems the chlorine consumption is reduced. We aim to be able to completely eliminate the use of chlorine and chemical oxidation in both public and private pools.

| Electro chlorinator | Electro chlorinator Electro chlorinator for the on site generation of hypochlorite from salt. The equipment presented will produce 2 kg per day of chlorine, which is sufficient for most small 25m public swimming pools using Dryden Aqua AFM® systems. For larger pools or heavily used pools two of the standard SCT units may be required. The SCT units offer major advantages with regards to simplicity, safety and cost, and if two units are employed on an installation the equipment gives a high degree of security. The equipment is manufacture in the UK and carries a 5 year warranty. |

| Bego Multiport valve | Why you should you change to Besgo simple design giving outstanding reliability lower cost and much simpler to install than a valve manifold multiport rotary valves restrict water flow, increase back pressure and make the pumps burn more energy, the besgo valve does not restrict water flow and saves energy. Example a 2" valve will save approx 0.3kw/hrs at 0.12 pounds UK per kw/hr this equates with 350 pounds per year the low pressure droop also means the media can be pack-washed more efficiently valve fails safe in the event of a power failure space saving, the valve is easy to fit in tight spaces

| Dosing pumps | Accurate peristaltic dosing pumps used to dose NoPhos, PAC and chlorine. Two models are available, the single headed pump may be used to dose one of the flocculants, however we also have two headed pumps, so the one pump can be used for APF ( or PAC) and NoPhos at the same time. Single headed pumps 0.03 to 0.38 litres per hour more information Double headed pump 0.04 to 0.76 litres per hour more information |

- Disinfection
- of changing rooms
| The spread of infection is always a risk in any changing room, especially in the warm wet environment of a swimming pool. Dryden Aqua now have for the first time an ozonation system which can be used to eliminate odours and help to disinfect all surfaces in the changing room. The system is automatic, it simply turns on for a period of around 1 hour every night by a time switch. Ozone at a level of approximately 0.5ppm will develop, however the ozone will tend to concentrate on all wet surfaces in contact with the air. Ozone has 7 times the oxidation capacity of chlorine, so very quickly the bacterial levels in the changing rooms will be greatly reduced or will be eliminated. |

| Water filters for the freshwater makeup | Prevent cryptosporidium entering your swimming pool by filtering all of the in coming water down to 1 micron with our ultra filtration system. The standard filter will cope with flow up to 1 cubic metre of water per minute, or continuous flow of approx 10 cubm/hr. The filter elements will last for approx 1 year, but this is dependent on how good the mains water supply is entering the building. |

| Phosphate test kit | This Phosphate Test kit includes 10 powder pillows, two testing vials and a reference card with directions. Gives accurate results after only 60-seconds, and measures phosphate from 0 to 1000 ppb. 10 test per bottle. The low end resolution is approx 10 ppb, this means the test kits is ideal to insure that there is Zero phosphate in the water. Ideal product to use in combination with NoPhos |
