Electrochlorination plant designing and manufacturing specialists, KALF ENGINEERING PTE LTD has many years on site working experience providing a complete service. From designing, manufacturing, delivering the equipment to site, installation of all mechanical and electrical components, co-ordinating with sub-contractors to complete civil works including concrete slabs or fencing, right through to commissioning and training.
Our systems are now providing the most advanced electrochlorination equipment available as well as a technically superior design for energy efficient long-term plant operation. Also replacing electrolyzers for the systems available worldwide manufactured and supplied by KALF ENGINEERING under the brand names of “elysisPURE”.
Kalf Engineering are experts in the area of environmentally friendly electrolytic water disinfection. Through extensive R&D (research & development), we are able to offer solutions covering a wide range applications, with our well established product, SKDisinfector, for application in different areas:
WHAT IS ELECTROCHLORINATION?
elysisPURE series Electrochlorination Generator produce the disinfectant sodium hypochlorite from sea water or salt water (Brine) on your own site.
Sodium hypochlorite is a chemical compound with the formula NaOCl.
NaOCl solution is commonly known as bleach and is frequently used as a disinfectant or bleaching agent.
Sea water or refined salt is mixed with softened water in the saturator to from saturated brine. It is diluted to 3% by softened water and injected into the electrolyzer. The solution is then electrolyzed with direct current (DC power).
The anode produced is chlorine gas and the cathode produced is sodium hydroxide and hydrogen. These two substances react with each other to form sodium hypochlorite solution.
Within the elysisPURE Electrolyzer, the seawater or brine solution, which is a good conductor of electricity, supports a current applied between the positive and negative electrodes, thus electrolyzing the sodium chloride solution. This results in chlorine (Cl2) gas being produced at the positive electrode (anode), while sodium hydroxide (NaOH) and hydrogen (H2) gas is produced at the negative electrode (cathode). The chlorine further reacts with the hydroxide to form sodium hypochlorite (NaOCl).
The employment of SK-CLE system fulfils the hygienic requirements and ensures a safe and economic operation.
Avoidance of transport, storage, handling and dosing of dangerous chlorine gas or highly concentration chlorine solution.
On- site production and notably longer Stability of products.
Saving on expensive chlorine deliveries and safety expenses.
Adjustment to requirement variations, water and system parameters and local weather conditions.
Safe operations, reduction in personnel.
KALF is the market leader in the on-site generation of sodium hypochlorite from fresh water, having over 25 installations worldwide. The brand of elysisPURE on-site sodium hypochlorite generating systems range in capacity from 24 to 48,000 kg/day of chlorine equivalent and generate a 0.2-0.8% sodium hypochlorite solution using three common consumables: Salt, water and electricity.
Depending on application or site special needs, elysisPURE systems are available as skid-mounted or component-based systems. The skid-mounted systems are fully operational and generating sodium hypochlorite within short period.
elysisPURE systems had been used for bio-fouling control in power plants, cooling towers, liquefied natural gas (LNG) terminals, offshore platform and desalination facilities, as well as coastal installations using seawater for cooling or other process needs all over the world.
elysisPURE series Electro-Chlorinator is a alternative disinfection system for small or large water treatment systems. They will found it beneficial because of its cost-effectiveness, easy to operate and eliminates potentially dangerous handling and storage problems associated with other types of disinfection practices. On-site Sodium Hypochlorite (NaOCl) generation requires only sea water and electricity to produce sodium hypochlorite. Sodium Hypochlorite generated on-site always maintains its strength, unlike conventional 12% to 15% hypochlorite purchased, which would be degraded over time.
Continuous process and produce consistent NaOCl quality
(No down time required for regeneration process and simple operation).
Fully insulated – no exposed DC busbar or electrical connections for greater personnel safety.
Cost effective, reliable.
Forced air hydrogen gas dilution and purging.
Titanium with DSA coating (platinum-Iridium) on anodes for increased efficiency.
Integral voltage monitoring.
Reduce facility requirements.
No Hazardous waste stream.
Best use of space (i.e. Modularly built, easy expansion etc)
On line monitor control.
Anodes used in our Electrolyzer cells are Titanium with DSA coating series (platinum-Iridium)
The anode substrate used are of Titanium Plates
Our unique design of electrolyser ensures easy removal of Hydrogen
Electrochlorinators based on elysisPURE Brine series are highly economical and use lesser power & salt
There is no hazardous waste stream
Best use of space (i.e. Modularly built, easy expansion, etc.)
On line monitor control
