Grundfos Disinfection Systems

Grundfos Disinfection Systems are designed for water treatment applications where controlled disinfection is required to help manage biological growth, support water quality, and protect water systems. These systems are used in municipal water treatment, wastewater treatment, industrial process water, cooling water, swimming pool treatment, and other applications where accurate and dependable disinfectant generation or dosing is important.

The Grundfos disinfection range includes technologies for chlorine, chlorine dioxide, and electrochlorination applications. Within this range, Selcoperm systems are used for on-site sodium hypochlorite generation, while Vaccuperm systems are used for vacuum-based chlorine gas dosing. Grundfos lists Selcoperm as an electrochlorination system that produces hypochlorite solution from common salt using electricity, and Vaccuperm as VGA, VGB, and VGS chlorine gas dosing systems.

Grundfos Selcoperm Electrochlorination Systems

Grundfos Selcoperm systems are electrochlorination systems designed to produce sodium hypochlorite solution on site from a common salt solution and electricity. Instead of relying only on delivered bulk disinfectant, Selcoperm allows facilities to generate disinfectant directly where it is needed, supporting safer storage, controlled production, and dependable disinfection for water and wastewater applications.

In the electrolysis process, sodium hypochlorite is generated from salt solution and can then be dosed into the piping system using a dosing pump. This makes Selcoperm useful for drinking water treatment, wastewater treatment, swimming pool water treatment, industrial process water, and cooling tower applications where consistent hypochlorite production is needed.

Grundfos Selcoperm SES model capacities listed in the Grundfos Product Center include 110, 220, 450, 900, and 1,800 g/h, depending on the selected model. These options allow the system to be matched to different disinfection demand levels in municipal, commercial, and industrial water systems.

Typical Selcoperm Applications

On-site sodium hypochlorite generation
Drinking water disinfection
Wastewater treatment
Swimming pool water treatment
Industrial process water disinfection
Cooling tower water treatment
Municipal water treatment systems
Applications where on-site disinfectant production is preferred

Grundfos Vaccuperm Chlorine Gas Dosing Systems

Grundfos Vaccuperm systems are chlorine gas dosing systems used for controlled water disinfection. The Vaccuperm range includes VGA, VGB, and VGS chlorine gas dosing equipment, with model configurations selected according to dosing capacity, connection type, valve type, manometer arrangement, and filter position.

Vaccuperm systems use the vacuum principle for chlorine gas dosing. Grundfos documentation explains that chlorine gas pressure is reduced to vacuum, which helps avoid chlorine gas leakage; in the event of pipe breakage, ambient air is drawn in instead of chlorine gas escaping. This makes Vaccuperm suitable for engineered chlorination systems where safety, control, and reliable dosing are key design priorities.

Grundfos literature describes Vaccuperm chlorine gas dosing systems for capacities from 25 g/h up to 20 kg/h. Some product listings show VGB model configurations with dosing ranges from 100 to 2,000 g/h, while broader Vaccuperm lines can cover higher dosing capacities depending on the selected system.

Typical Vaccuperm Applications

Chlorine gas dosing
Municipal drinking water disinfection
Wastewater treatment chlorination
Industrial water treatment
Cooling water disinfection
Process water treatment
Centralized chlorination systems
Applications requiring vacuum-based chlorine gas safety control
