Chlorine Dioxide

Today, applications of Chlorine Dioxide are very diverse. Chlorine Dioxide can be used for the purification of water in;

  • Commercial buildings
  • Critical care areas in hospitals
  • Food processing plants
  • Industrial cooling water systems

Whatever the size or complexity of your application Ph Water Technologies has a system to suit your needs; ranging from small borehole treatment systems, through to custom engineered generation systems used in data centres.

Ozone

Ozone is a useful disinfectant as oxygen gas in the ambient atmosphere,  can be converted to ozone onsite.

Advantages

  • Once it has deactivated the biological load, can be reduced back to oxygen and assuming no other chemicals are involved be discharged into a drain.
  • “Greener Approach”
  • Can remove some of the health and safety concerns of handling other chemicals

Ph Water Technologies can offer ozone treatment for the biological control of cooling towers, tanks and process water.

UV- Ultra Violet Light Disinfection

How does UV disinfection work?

UV disinfection uses light at wavelengths of 260-270 nano metres known as UV-C to break the molecular bonds within nucleic acids within the DNA of microorganisms.This will kill or deactivate the bacteria and prevent it from reproducing.

UV technology is widely accepted as the primary method of disinfection for potable drinking water- offering a 3 log (99.9%) reduction in targeted organisms.

Advantages

UV disinfection’s key benefit is the deactivation of microorganisms such as Legionella, Giardia, Cryptosporidium and viruses in drinking water without producing any known disinfection by-products.

UV is deemed as a point of use (POU) disinfection as it does not offer any residual disinfection downstream of the unit.

Ph Water can provide a range of UK manufactured, WRAS approved UV disinfection systems.

Chemical Dosing

Water treatment is achieved by injecting chemicals into a water system.

Advantages
  • Prevent corrosion within the water system
  • Combat biological load
  • Prevent Proliferation of bacteria

This can be offered with a simple dosing pot or automated dosing pot.

Simple dosing pots, which is the  cheaper option, requires the manual decanting of chemical into the circuit.

An automated dosing pump removes this manual handling and will dose a specific volume of chemical from a drum as programmed by the pump interface.

Water Conditioners

Water conditioners are an alternative to water softeners without the need to use ion change. They use either zinc liberation, magnets, catalytic reactions or seed creation.

This method prevents the creation of hardness salts within your potable or hot water system.

Advantages
  • System does not need to regenerate
  • Does not need to be supplied with salt
  • Reasonably maintenance free- can reduce operational costs of the building

Water conditioners are usually installed inline on the cold water services- this means they require less plant room space.

The key difference between the softener and water conditioner is the longevity of the treatment, where an ion exchange process is permanent a water conditioners effect is limited and can be undone when water is put under duress. PH Water Technologies supply a range of units suitable for all applications.

Reverse Osmosis

What is Osmosis?

Osmosis is a specialist type of diffusion where fluids are separated by a semi-permeable membrane. The driving force of this process is the difference between the concentrations of the two solutes separated by the membrane. In traditional osmosis fluids move from areas with a lower concentration to areas with a higher concentration of solutes- usually equalising the concentration gradient between each side of the membrane.

Reverse Osmosis

Reverse osmosis (RO) differs from traditional filtration due to the method of fluid transfer, as it is via osmosis as opposed to flow through. RO uses a pump to increase the pressure on one side of the semi-permeable membrane and force the solvent through. The membrane is size graded to be able to filter undesirable particles out of solution.

Essentially the process of RO is traditional osmosis but in reverse. Osmosis in the natural world happens without the use of energy whereas RO does require energy.

How RO can be applied

This can be used in cases where product water requires the removal of its dissolved minerals, for example to provide make-up water to steam raising boilers, increase cycles of concentration in cooling towers or provide high quality water to industrial, pharmaceutical or food and beverage process.

PH water can offer systems to accommodate 10’s of litres per hour to 1,000’s of litres an hour, all systems are made to order and if required personally tailored to your process.
