The machine comes complete with a brine (salt solution) tank and 75 kg of salt to enable the machine to be commissioned and put in to service. Further supplies of salt can be purchased from us or a local supplier. The quality of the salt is important as contaminants can affect the correct functioning of the machine. You will find on page 11 a recommendation for the specification of the salt. In order to commission the machine the technician needs to know the hardness of the local water supply in order to set the built in water softener to the correct regenerating cycle. The machine also has a built in 50 Micron filter to remove particulates that could affect the optimal performance of the generator. If however your water supplyhas a high level of sediment we would recommend the fitting of an external filter between the potable water supply point and the machine.

High levels of Iron and Manganese can adversely affect the performance of the generator cell. Whilst the inbuilt softening system will remove low levels of these contaminants if the level is above 1 mg/L for iron and 0.1 mg/L for manganese we would recommend that a separate removal system be installed. Our technical sales people will be happy to advise you on this point. If you are using well water and it is contaminated with oxidized Iron or Manganese (the water often takes on a red/ brown colour) a separate removal system is always necessary.

The generator requires a three phase 400 volt 50Hz power supply located within 3 meters of the machine plus a potable water supply of between three and seven bar with a shut off valve terminating in a fitting within 2 meters of the machine. Full specification and requirements of the machine are laid out on page 11. There should also be a suitable wastewater point or connection within 3 meters of the machine.

In addition if you have opted for remote monitoring and alerts via your Ethernet you must provide a lead terminating in an RJ 45 plug.

If you have opted for GPRS alerts it is necessary to check the availability of a cellular network in that area simply by seeing if your mobile phone has a good signal strength in that position.

The generator should be located in a frost free well ventilated room close to the selected dosing point in your water system. If the generator is located in a small confined space without adequate ventilation it is necessary to fit an exhaust system which our staff will be able to advise you on.

Why use dangerous chemicals when there are safer more environmentally friendly alternatives ?

Every year people are injured and some even killed with accidents involving Chlorine gas. Some of these are caused by accidents involving delivery systems and some by incorrect mixing of cleaning and disinfecting chemicals.

Chlorine and its chemical compounds are extremely effective as disinfecting agents and the safety of our modern food and water supply chain depends heavily on them. The struggle has been to maintain the safety of the food and water supply chain whilst protecting the health and lives of those working in these areas.

Now with the use of a DCW generator it is possible to generate Hypochlorous Acid on site from just salt water and electricity safely.

Hypochlorous Acid is one of the most powerful chlorine based disinfection agents. At a concentration of just 0.1 parts per million with an ORP of +700mv and pH 7 it can achieve a log3 reduction of E.coli within 10 seconds. (Source: Carlson, S.: Fundamentals of water disinfection. J. Water SRT – Aqua 40 (1991) 346-356)

Using state of the art patented Membrane Electrolysis technology DCW generators produce powerful disinfection agents on site without any risks to humans.

The added bonus is that our disinfection liquids are classed as non toxic and biodegradable under EU guidelines thus helping protect both people and the environment.

All these benefits are coupled with the possibility of making substantial cost savings in many circumstances as on site production is often substantially cheaper than using traditional chlorine based chemicals.

The DCW generators can also save energy and water as they allow some processes to be carried out at lower temperatures and water to be recycled.

How does the system work ?

Our disinfectant generators produce a liquid called NEUTHOX through the process of electrolysis of Brine (Salt Water). NEUTHOX contains among other things Hypochlorous Acid that is a highly potent bactericide.

Bacteria such as Escherichia coli when exposed to Hypochlorous Acid lose viability in less than 100ms. Escherichia coli is a major cause of food and water borne infections in humans.

In addition to killing bacteria NEUTHOX is effective in breaking down Biofilms which protect the bacteria from the action of the Hypochlorous Acid.

Hypochlorous Acid is an effective disinfection agent against most bacteria that cause infections in humans such as:

• Legionella pneumophila
• Vibrio vulnificus
• Escherichia coli
• Listeria monocytogenes
• Salmonella enterica
• Campylobacter jejuni

NEUTHOX also contains Sodium Hydroxide which is a useful cleaning agent due to its ability to break down grease and proteins.

DCW generators can also be configured to produce two separate solutions Cathox (mainly a solution containing Sodium Hydroxide) and Athox (the disinfection solution containing Hypochlorous Acid).

The NEUTHOX can be either dosed directly into your system or alternatively into a buffer tank, if the demand is variable, then through a sensor controlled dosing pump to suit the biological load within your system.

The only requirements for our generators to work are a supply of salt, water and electricity. The generators are controlled by PLC with an easy to operate HMI (Human machine interface) allowing the end user to accurately control the pH value of the NEUTHOX and ensure the correct dosing levels for a particular application.

Brew and Beverage Industry

DCW disinfectant generators have a number of applications in this industry. They include Tunnel Pasteurizers, Bottle Wash and cleaning of Conveyor and Transport Systems. The use of a DCW generator can result in significant savings as it allows processes to be run at lower temperatures and water to be recycled.

Cooling Towers and Ponds

NEUTHOX produced by our on site generators effectively controls Legionella and other bacteria maintaining a safe and healthy environment. The powerful disinfecting solution also destroys bio-film yet is no more corrosive than tap water.

Meat Industry

Bacterial contamination of meat is an ever present problem. DCW can help with its powerful NEUTHOX solution ideally suited to surface cleaning of preparation areas, packing cases and transport systems yet without the problems associated with traditional chlorine based chemicals.

Drinking Water

NEUTHOX is approved for use as a disinfection agent for drinking water making it safe for consumption without the unpleasant smell and taste associated with conventional chlorine based water treatment.

Fruit and Vegetable washing

NEUTHOX is a highly effective disinfection agent for the washing of Fruit and Vegetables both whole and cut, increasing the shelf life and providing a safer product for consumers.

Waste Water Treatment

The addition of NEUTHOX to waste water can reduce bacterial count to safe levels without contaminating the environment.

Horticulture

Misting or spraying glasshouses with NEUTHOX gives effective bacterial and algal control.

Food and Dairy Industry

Due to its non-toxicity NEUTHOX is approved for use in the food industry for disinfection in a wide range of areas including prepa-ration surfaces, pipes, transport systems and packaging.

Agriculture

The use of NEUTHOX in agriculture can result in increased yields and improved animal husbandry by destroying bacteria in animal drinking water and stock pens.

Marine Industry

NEUTHOX generators are suitable for shipboard sterilization of drinking water. NEUTHOX can also be added to water used in ice making machines for the fishing industry to ensure a safer product.

Swimming Pools

On site NEUTHOX genera-tors can ensure a safe swimming environment without the unpleasant smellor eye stinging effects of traditional chlorine based treatments. It also is safer for staff as they do not have to handle potentially dangerous chemicals.

Medical Facilities

Due to its non-toxicity and noncorrosive nature it is ideal for surface sterilization of medical facilities to help prevent bacterial infection.

Shellfish Industry

NEUTHOX has been shown to be highly effective in destroying bacteria such as Vibrio and E.coli. making for a safer product for consumers.

Hotels and Public Facilities

Legionella is a major health problem in facilities with a large water system where parts are not often used such as Hotel rooms in low season. The unused areas can result in the build up of Legionella and other health endangering bacteria within the water system. The addition of a Neuthox generator to the water system can prevent this without costly high temperature flushing.
