Biofouling (generating) control products


H2O BFS is capable to provide the required product to control biofouling. The choice of product depends on local site specific conditions and specifications. Our WATER-TOP program will assist the client to make the correct choice of biofouling control product for their system. The required capacity of the generation system is tailored according our Ecodosing method.

Benefits H2O package

To ensure an effective biofouling control of the water system is provided, H20 offers a complete integrated solution, providing the additional services to a product:

  • Applying the most suitable product for the water system at the lowest capital investment costs
  • Achieve an effective control of biofouling growth, both macro and microfouling
  • Design of the dosing system and lines, including fabrication drawings
  • Verification of dosing adequacy using CFD modeling,
  • Biovision Monitor, installed at critical equipment e.g. heat exchangers, media filters to provide visual verification of any risk of biofouling buildup
  • Achieve the lowest O&M costs
  • Guarantee on both the equipment AND on the efficiency of the biofouling treatment!


Below are some of the products presented which H2O BFS can provide, this includes the engineering, dosing system and required chemicals.




H2O provides Electrochlorination systems. The range of Electrolyzers are designed for low-maintenance Sodium Hypochlorite (NaOCl) production for on and offshore application. H2O can supply both concentric tube and parallel plate electrolyzer technology to form a range of systems to suit most applications. Additionally, they can also be supplied for non-hazardous and hazardous. The systems can be supplied for installation in both classified and unclassified areas installation. The are fully automated units manufactured to comply with clients unique specifications, applications, and globally recognized standards.

Electrochlorination is the process of producing a non-hazardous chlorine equivalent by the electrolysis of a brine/seawater solution to form a sodium hypochlorite solution. Sodium hypochlorite is an industry-standard oxidizing agent for an extensive list of applications, from marine biofouling control to potable water disinfection.


  • Proven technology for hypochlorite production
  • On site production of hypochlorite
  • No logistics with hazourdous chemicals
  • Low O&M costs

Brine based electrochlorinator


H2O provides brine based electrochlorination packages. A Brine System is the description given to an Electrochlorination Package that instead of using seawater for an electrolyte the electrolyte is manufactured on site from salt and town water utilities.


  • Suitable for potable water treatment 
  • It is not dependent on a coastal location
  • The Sodium Hypochlorite product is more concentrated
  • There are no hydroxide by-products to manage
  • There is often no requirement for acid cleaning of the electrolysers
  • The dosing system is less onerous to design as the media velocities are not critical
  • The balance of plant for dosing and storage is of smaller capacity due to the higher product concentration
  • Batch production can be employed

Chlorine dioxide


Chlorine dioxide(ClO2) is a technology which has been historically applied at large scale (recirculation) cooling water systems. Additionally, chlorine dioxide generators are being increasingly used as an alternative to chlorine generators in water treatment/disinfection processes, as they release lower quantities of toxic impurities into the atmosphere as compared to conventional chlorine based generators and hence also require lower dosing numbers. Chlorine dioxide generates the product in situ which prevents storage of the product or risks of exposure to high concentration of the product, it has proven to be a safe technology.


  • Excellent effectiveness against biofilms and algae 
  • Effective at low dosage rates in contaminated systems compared to alternative biocides 
  • Non-Reactive with Organics to form THMs 
  • Non-reactive with ammonia-nitrogen 
  • Disinfection is less dependent on pH 
  • Effective over a broad pH range 
  • Does not react with triazole corrosion inhibitors



The unique patented product, the ‘Biobullet’, were developed by leading scientist at Cambridge University. The products are optimally engineered to remove costly biofoulers from industrial infrastructure, thereby increasing the efficiency and lifespan of industrial plants and their component parts.

BioBullets’ products are effective against a range of nuisance pests including mussels, oysters, clams, tunicates, barnacles, bryozoans, hydrozoans and sponges.

For mussel control, we estimate that encapsulation of the active facilitates use of 1000x less product than freely dosing. Encapsulation also facilitates use of environmentally friendly actives.



  • Products are dosed during routine plant operation
  • Only one short annual dosing period is needed (max 10 days) to mitigate biofoulers
  • Pipe corrosion is reduced
  • Fully biodegradable and no harmful byproducts 
  • There is no need for chlorine
  • Accepted as an environmentally friendly product
  • Non-oxidant, stable product with no need to neutralize
