OUR CHLORINE DISINFECTION SYSTEMS

Three Ways to Disinfect with Chlorine, Safely

Choose low-strength onsite generation for simple, non-hazardous dosing, high-strength onsite generation for large plants with limited storage space, or chlorine dioxide where biofilm, Legionella or disinfection by-products are the main concern.

Skid-mounted electrochlorination system with tubular electrolytic cells, brine tank and softener01

ONSITE CHLORINE GENERATOR · EQUIVALENT CHLORINE 0.8%

Low-Strength Onsite Chlorine Generator (0.8%)

An electrochlorination system that passes diluted brine through an undivided electrolytic cell to produce a 0.8% sodium hypochlorite solution (about 8 g/L of available chlorine). The solution is stored in a day tank and dosed with standard metering pumps. Hydrogen, the only by-product, is safely diluted and vented.

  • 0.8%equivalent chlorine (8 g/L)
  • 1–1,000+ kg/daymodular, cells in parallel
  • ~3 kg saltand ~4.5 kWh per kg chlorine
  • Non-hazardous solution below 1% strength
  • Titanium DSA-type coated electrodes
  • Water softener, brine saturator and rectifier
  • Hydrogen dilution blower and vented storage
  • Automatic start / stop on tank level
  • Lower pH impact and less scaling than bulk bleach

Ideal for: drinking water plants, STP / ETP disinfection, swimming pools, hotels, hospitals, townships, cooling towers and food plants.

Membrane-cell chlorine generation plant with electrolyzers and hypochlorite storage tanks02

ONSITE CHLORINE GENERATOR · EQUIVALENT CHLORINE 12.5%

High-Strength Onsite Chlorine Generator (12.5%)

A membrane-cell electrolyser splits purified brine into chlorine and caustic soda in separate chambers. The two are then reacted to form commercial-strength 12.5% sodium hypochlorite. The same plant can also supply caustic soda for pH correction, or chlorine gas at below atmospheric pressure where required.

  • 12.5%commercial-strength hypochlorite
  • 0.1–20 TPDequivalent chlorine
  • 1/15 storagevolume vs 0.8% solution
  • Ion-exchange membrane electrolysers
  • Brine purification with chelating resin softener
  • Co-produces caustic soda (NaOH)
  • Optional chlorine gas output at low pressure
  • Replaces bulk 10–12.5% bleach deliveries
  • PLC / SCADA control, skid or containerised build

Ideal for: municipal water and sewage utilities, large desalination and reuse plants, industrial estates, power plants and remote sites with long chemical supply chains.

Wall-mounted chlorine dioxide generator cabinet with dosing pumps and chemical drums on spill pallets03

CHLORINE DIOXIDE · GENERATED ON DEMAND

Chlorine Dioxide System

Chlorine dioxide cannot be stored or transported, so it is generated at the point of use. Our systems react sodium chlorite with hydrochloric acid (acid-chlorite process), or with hypochlorite and acid (chlorite-chlorine process), in a closed reactor and dose the solution directly into the water.

  • 5 g/h–200 kg/hClO2 output
  • pH 4 – 10stays effective across range
  • 0.25 – 1 ppmtypical residual in cooling water
  • Removes and controls biofilm in pipes and loops
  • Strong Legionella and Pseudomonas control
  • Does not form THMs or chlorinated organics
  • Oxidises iron, manganese, taste and odour
  • Batch or continuous submerged-reactor designs
  • Residual analyser, leak and level interlocks

Ideal for: cooling towers, hospital and hotel hot water systems, food and beverage plants, dairies, breweries, poultry drinking water, produce washing and distribution networks.

HOW IT WORKS

From Salt to
Safe Disinfectant

NaCl + H2O + electricity → NaOCl + H2

Softened water dissolves food-grade salt into brine. A low-voltage DC current from the rectifier converts the brine into sodium hypochlorite inside the electrolytic cell. The solution is stored in a vented tank and dosed in proportion to flow or residual chlorine. For chlorine dioxide, two precursor chemicals react in a closed reactor and the ClO2 solution is injected straight into the water.

WHY GENERATE ON SITE

Onsite Generation Compared with Delivered Chlorine

ParameterOnsite GenerationChlorine Gas CylindersDelivered Bulk Bleach
Safety riskLow, no toxic gas storedHigh, toxic gas leak riskModerate, corrosive liquid
Supply chainOnly salt deliveriesCylinder refills and transportFrequent tanker or drum deliveries
Product strengthConsistent, always freshConsistentLoses strength during storage
Chlorate build-upLow, product used quicklyNoneRises with age and heat
Operating costLow, salt and power onlyLow chemical cost, high safety costHighest per kg of chlorine
Permits & complianceSimplestStrictest licensing and safety rulesHazardous chemical storage rules

In hot climates such as the GCC, delivered bleach loses strength faster and forms more chlorate, which makes onsite generation especially attractive.
