Barrier® UV systems
Barrier® UV systems provide a cost-eff ective, reliable, operator-friendly disinfection solution for industrial water treatment applications.
For single-pass or closed-loop disinfection applications where chemicals are not wanted or allowed, Barrier® UV systems represent a cost-eff ective solution.
Flows from 1 m3/h up to over 1000 m3/h can be treated with a single system.
Depending on the type of application, the perfect system can be selected from a range of low pressure, Amalgam or medium pressure lamp based UV systems.
The UV-C light generated by Barrier® systems is absorbed by the microorganism and destroys the reproduction mechanism.
Additionally, due to the wide emission spectrum of the medium pressure lamps in Barrier® M systems, the photoreactivation eff ect is blocked, providing extra safety.

UV sensor
Barrier® A and Barrier® M systems are equipped with a calibrated absolute UV sensor as standard, to monitor the disinfection process.

 

Barrier® UV systems

Certified by the industry-leading DVGW* and in accordance with the protocol W294, the systems provide a guaranteed minimum Reduction Equivalent Dose (RED) of 400 J/m2 **.
For small-sized drinking water installations Barrier® A systems are designed based on high-effi ciency Amalgam lamps.
The compact Barrier® M range, based on very powerful medium pressure lamps, is the perfect solution for medium-sized drinking water disinfection applications.
UV-C light generated by Barrier® systems is absorbed by the microorganism and destroys the reproduction mechanism.
Additionally, due to the wide emission spectrum of the medium pressure lamps in Barrier® M systems, the photoreactivation eff ect is blocked, providing extra safety.
The DVGW protocol is also accepted by the US EPA*** which specifies in the UV disinfection guidance manual that UV disinfection is a reliable process for the inactivation of Cryptosporidium and Giardia.
* DVGW - Internationally recognised authority on certifi cation of UV disinfection systems. (DVGW - German Technical and Scientific Association for Gas and Water)
** 400 J/m2 = 40 mJ/cm2
***EPA - Environmental Protection Agency

UV sensor - DVGW
One or more UV sensors monitor the disinfection process continuously by measuring the UV-C intensity inside the UV chamber.
The measured absolute values are displayed on the control panel in W/m2.
In the case of a UV alarm both a dry contact and an indication on the display are activated.
The DVGW certifi ed UV sensor is designed in accordance with the DVGW directive W294.
The absolute calibrated sensors are placed in a monitoring window which enables the operator to check the duty UV sensor(s) during the disinfection process withoutinterruption.

 

Barrier® M UV systems
Barrier® M UV systems provide a cost-effective, reliable, operator-friendly chloramines reduction solution for pool water treatment installations.
A typical problem for indoor pools is the so-called “pool smell” which is a synonym for a poorly performing water treatment system.
Chloramines (or combined chlorine) result from the reaction between free chlorine and ammonia.
Ammonium is introduced to the water predominantly by swimmers.
For the breakdown of chloramine, the spectrum of the UV lamp used is very important.
Depending on the type of chloramine, different wavelengths are required for the photolysis process such as:

• Monochloramine - 245 nm
• Dichloramine - 297 nm
• Trichloramine (nitrogen trichloride) - 260 & 340 nm

Barrier® M systems are equipped with medium pressure UV lamps as standard which have a wide energy spectrum range - providing the perfect solution to break down combined chlorine effectively and economically.
In addition to being used for chloramine reduction, Barrier® M systems will also improve the microbiological water quality because UV is also a very eff ective technology for the inactivation of bacteria, viruses and protozoa such as Cryptosporidium and Giardia.
 

UV sensor
A UV sensor monitors the disinfection process continuously by measuring the UV-C intensity inside the UV chamber.
The measured absolute values are displayed on the control panel in W/m2 or %. In the case of a UV alarm, both a dry contact and an indication on the display will be activated.
The UV sensor is factory calibrated and, due to the high quality optical components which are used, is a reliable tool to monitor the disinfection process.
The UV sensor is positioned in the wall of the chamber and is in direct contact with the process water.

 

Barrier® M UV systems
Barrier® M UV systems provide a cost-effective, reliable, operator-friendly disinfection solution for small and medium-sized wastewater plants.
By disinfecting the water with Barrier® M UV systems, no chemicals or contact tanks are required.
An increasing number of wastewater treatment plants are using closed piping systems instead of open channels to transport water.
A Barrier® M system can easily be incorporated in a closed piping system.
Advantages of a closed UV system over an open-channel UV system are numerous, including
1) no need for costly concrete channels,
2) much smaller footprint,
3) no need for lift ing devices used for modules and racks,
4) no need for level control devices,
5) no risk of exposure to harmful UV light, and
6) easier maintenance, e.g. changing lamps and cleaning.

For small and medium-sized wastewater disinfection applications, the very compact Barrier® M range of systems, based on powerful medium pressure lamps, is the perfect solution.
Compared with low pressure based open channel systems, only a very small footprint is required.
The UV-C light generated by Barrier® M systems is absorbed by the microorganism and destroys the reproduction mechanism.
Additionally, due to the wide spectrum of the medium pressure lamps, the photoreactivation effect is blocked, providing extra safety.
For high LOG reduction results, a low suspended solids level is required in the water to be treated.

Chlorine dioxide generator

The chlorine dioxide generator DIOX-A 10 was designed for the preparation of small quantities of chlorine dioxide.
As starting chemicals for the preparation of chlorine dioxide Cedolyt A9 (dilute hydrochloric acid, 9 %) and Nadolyt C7.5(dilute sodium chlorite, 7.5 %) are used.
Both solutions are fed from standard carboys directly into the reaction tank where the sodium chlorite and the hydrochloric acid are converted into chlorine dioxide.
Chlorine dioxide is a powerful disinfectant and oxidising agent, excellent at destroying odours.
Chlorine dioxide has been found to be superior to chlorine as a disinfectant.
This chemical has a higher oxidising reduction potential than chlorine and can achieve destruction of such organic substances and virus which are not attacked by chlorine.
At identical concentrations the capability of chlorine dioxide to destroy spores and virus is higher than that of chlorine.
The use of chlorine dioxide eliminates the formation of undesirable or harmful trihalomethanes (haloforms).
Chlorine dioxide oxidises unpleasant pollutants such as phenols, algae and products resulting from their decomposition into neutrally tasting substances.
 

Chlorine dioxide generator
Acid/chlorite process using dilute reagents

The Wallace & Tiernan Chlorine dioxide generator DIOX-A was developed for the preparation of chlorine dioxide up to a capacity of 250 g/h.
As basic chemicals for the generation of chlorine dioxide this unit uses Cedolyt A9 (dilute hydrochloric acid, 9 % HCl) and Nadolyt C7.5 (dilute sodium chlorite, 7.5% NaClO2).
Both reagents are metered directly from commercial carboys or intermediate storage tanks into the reaction tower where a chlorine dioxide solution is produced.
The strength of the two basic chemicals is balanced in a ratio that ensures an optimal yield of chlorine dioxide.
The chlorine dioxide solution produced is directly metered via an injection unit into the water to be treated.

 

Chlorine dioxide generator acid/chlorite process

It produces an aqueous solution of chlorine dioxide of a constant strength.
As basic chemicals for the generation of chlorine dioxide this unit uses commercial grade hydrochloric acid (30 – 38% HCl) and Nadolyt C25 (sodium chlorite, 24,5% ClO2)

 

Chlorine dioxide generator Chlorine activated process

This type of unit uses Nadolyt C25 (sodium chlorite, NaClO2) and chlorine gas (Cl2) as the basic chemicals for the generation of chlorine dioxide.
Nadolyt C25 is metered into the unit directly from a carboy or a pumped system.
Three system types are available for capacities of 1500, 3000 or 4500 g/h chlorine dioxide.
Chlorine dioxide solution is produced in the reaction tank.
Once the chemicals have fully reacted, the concentrated chlorine dioxide solution is diluted with water at the reactor outlet before it is passed to the chlorine dioxide storage tank.
The quantity of the dilution water is adapted to the required strength of the chlorine dioxide.
This is adjusted to1 up to max. 3 g / l ClO2 depending on the demand.

 

Oxiperm OCG-166 systems generate 0.75 to 10 kg/h of chlorine dioxide directly on site according to the proven sodium chlorite/chlorine process.
The produced chlorine dioxide solution in the batch tank has a concentration of 3 g/l.
Usually, disinfection is the first step of pathogen reduction, in order to continue operating a drinking water installation.
An ideal means of ensuring the sterility of drinking water is to use chlorine dioxide as a disinfectant.
Chlorine dioxide is highly effective against all types of germs and has a long dwell time in the tubing system, which means it disinfects even without re-dosing.

Ozone provides high efficiency in water treatment for different applications end is environmentally friendly at the same.
Although, the market can offer other solutions in form of other disinfection methods, equipment and chemicals, ozone generator is very reliable, has wide range of applications and high efficiency in continuous 24h water treatment systems.
Ozone is an unstable molecule owing to the weak bonds holding the third oxygen atom.
This instability makes ozone a naturally powerful oxidizing and disinfecting agent.
Oxidation occurs when ozone molecules come in contact with oxidizable substances, including microorganisms (viruses, molds, and bacteria), as well as organic and inorganic compounds (metal ions, plastics and rubbers).

A Natural Disinfectant
In these reactions, the unstable third oxygen atom is transferred, with a large release of energy, from ozone to the molecule being oxidized.
The transfer of energy in oxidation causes the outer membranes of microorganisms to rupture.
As ozone molecules enter lysed microorganisms, genetic material (DNA and RNA) is oxidized and destroyed.
Oxidation typically hydrolyzes inorganic molecules, causing them to become insoluble, and facilitating removal by filtration.
Organic molecules most often disintegrate as a result of oxidation, destroying their biological activity.

Applications
Ozone has been utilized in municipal water disinfection for over 100 years and has very broad application potential in a variety of industries and applications:

• Bottled water and beverage
• Clean-In-Place (CIP)
• Food processing and preservationIndustrial process and cooling tower water
• LaundryGroundwater and soil remediation
• Marine and fishing fleet
• Aquaculture
• Municipal water and wastewater treatment

On site electrolytic chlorination system

OSEC®-A stands out by its compact and space-saving design, easy operation and low maintenance.
Different setting possibilities and monitoring as well as an integral chlorine gas detector guarantee highest operational reliability.
At the outlet of the electrolyser cell the chlorine generated by OSEC®-A is immediately dissolved in the water resulting in the generation of highly effective hypochloric acid (HClO).
Undesirable substances such as chlorate and bromate are not formed.
This type of electrolysis represents the purest and most stable disinfection solution.
In comparison, commercial sodium hypochlorite contains chlorate that is formed during the disintegration of the effective chlorine.
In addition, bromate is found in commercial sodium hypochlorite, a carcinogenic substance, for which a limit value of 0.025 mg/l is valid since 1.1.2003 in accordance with the Potable Water Act

 

On site electrolytic chlorination system

Electrolysers built to the tubular cell process, which are used as an alternative to chlorine gas systems, provide many safety features.
Risks inherent in the transport, handling and storage of chlorine gas or commercial sodium hypochlorite solutions are eliminated.
Local regulatory issues often limit the use of chlorine gas for safety reasons.
OSEC® systems produce directly on site sodium hypochlorite from a saturated solution of common salt and electricity.
Generation takes place on demand only.
The hypo produced in batch operation does virtually not degrade in strength even if it is stored over an extended period of time.
The anodes used are made from titanium with a precious metal coating.
This construction allows to grant a five calendar years warranty after installation and commissioning.
The cathodes are made from a special grade Hastelloy C.
Automatic control of the supply voltage combined with a programmable periodic cleaning cycle of the monopolar electrodes by dilute hydrochloric acid ensure a virtually operator-free performance.
The number of anodes in the electrolyser can be customised to produce the desired quantity of chlorine.
This system flexibility provides a signifi cant reduction in power requirements and plant cost.
An intelligent PLC control system provides for the fully automatic operation of the unit including all control, monitoring, alarm and interlock functions.
Having set the flow rates for brine and dilution water, all that remains on site is to turn the start switch.
Metering of the sodium hypochlorite solution is achieved by manually or automatically controlled dosing pumps.

 

OSEC® B-Pak System

Skid-Mounted On-Site Electrolytic Chlorination System
The OSEC® B-Pak system generates a 0.8% sodium hypochlorite solution through the electrolysis of brine, consuming only water, salt and electricity.
By producing hypochlorite on-site and on-demand, the system eliminates concerns associated with transportation and storage of liquefied chlorine gas or commercial sodium hypochlorite solutions, making it ideal for any application requiring chlorination.
Due to its low concentration, the hypochlorite solution generated by the OSEC® B-Pak system minimizes corrosionand degradation (loss of available chlorine during storage) issues typical of high-strength (12-15%) sodium hypochlorite solutions.
In addition, the system offers lower operating costs than commercial hypochlorite, typically resulting in att ractive payback periods.
The OSEC® B-Pak skid is a fully automated, pre-packaged on-site hypochlorite generation system designed for fast and economical installation, safe operation, and easy maintenance.
Skids are shipped intact and completely piped, wired and tested.Siemens Water Technologies is a global leader in chemical feed and disinfection solutions with thousands of electrolytic hypochlorite generation systems (brine and seawater based) installed around the world.

 

On site electrolytic chlorination system, 150–300 g/h chlorine

Electrolysers that are built to the tubular cell or membrane process, provide many safety features when used as an alternative to chlorine gas systems.
Transport and handling of chlorine cylinders is completely eliminated.
Also the mandatory chlorine store rooms with all their safety equipment such as sprinkler systems are no longer requiredwith this technology.

General
OSEC®-NT electrolysers generate on demand highly effective sodium hypochlorite from saturated brine, softened water and DC power.
All the problems associated with commercial sodium hypochlorite solutions, such as the poor stability in storage (degradation), laborious handling or dilution, storage of carboys, are eliminated by this on site generation.
The Wallace & Tiernan membrane process is based on specially coated anodes and cathodes that ensure a long service life for the electrolyser cell.
Unlike conventional membrane processes, the Wallace & Tiernan technology does not circulate chlorine laden lean brine in a loop via the salt saturating tank.
Thus no chlorine can escape to the ambient air.
All the salt used is completely converted into chlorine.
An intelligent PLC control and monitoring system with text display provides fully automatic operation.
Both OSEC®-NT capacity ranges of 150 and 300 g Cl2/h are built as very compact units: Hypochlorite and brine tank, control panel, rectifier, water softener and free space for two metering pumps is also incorporated into the compact skid.
Optionally the unit can be linked into standard bus systems allowing tele-monitoring via telephone cable.
