Air purification for pump wells

Professional air purification for pump wells

Industrial air cleaning with no filters or chemicals

What can the HS Purifier do for you?

HS Purifier forindustrial air cleaning use photolytical oxidation to purify the air from the gas, hydrogen sulfide (H2S). When the H2S level reduces significant, you will protect the electronic from the cabinet by the pump well. If the pump well is located close to a neighbor, then you also avoid neighbor complaints, because the odor is reduced significant. 

The HS Purifier is easy to install in any pump well, and like the rest of the JIMCO products, HS Purifier is running as an environmentally friendly professional air purification solution.

​JIMCO’s environmentally friendly technology takes basic in photolytical oxidation, and the technology can be used to purify both air and water without any use of chemicals or filters in the industrial businesses. 

JIMCO has won the EU´s environmental award for cleaner technologies and works to spread out the knowledge about environmentally friendly technologies, so the use of chemicals can be reduced.​

How does it work?

The HS Purifier will be installed in a pipe in the cabinet that ends in the pump well and is connected to 230 V power supply. 

Oxygen from the atmospheric air will by of JIMCO´s special UV-C lamps, turn into ozone as it is blown down in the pump well by a ventilator. The ozone reacts with the hydrogen sulfide and the following chemical reaction occurs:

O₃ + H₂S -> SO₂ + H₂O -> SO₂²⁻ og SO₃²⁻​

​This means that the hydrogen sulfide is oxidized into a sulfur compound and is therefore no longer dangerous or malodorous

Ozonation is 100% effective in converting H2S to sulfates

Reduces the gas, hydrogen sulfide effectively 

Sterilizes the air 

Odor reduction = No complaining neighbors

Avoid neighbor complains

Reduction with air purification without filters for pump wells HS Purifier

The reduction of hydrogen sulfide in % depends on the bacteria level in the putt, but an estimated

reduction in % based on feedback shows following:

  • 800 ppm – approx. 50% Reduction
  • ​300 ppm – approx. 67% Reduction
  • 100-150 ppm – approx. 80% Reduction
  • ​60 ppm – approx. 90% Reduction​

Facts about hydrogen sulfide

Hydrogen sulfide is an inorganic chemical compound with the formula H2S. Hydrogen sulfide is very poisonous, corrosive, and flammable and a mixture of H2S and air can be explosive.​

With a content of hydrogen sulfide in the air on:

  • Less than 0,01-0,02 ppm can the sense of odor start to reveal hydrogen sulfide
  • ​By 1 ppm experiences a weak, but unmistakable odor
  • ​By 3-5 ppm feels a strong odor of hydrogen sulfide
  • ​By 20-30 ppm do you feel at clear and unpleasant odor
  • ​By 30-150 ppm then can the odor be experienced as sweetish
  • ​By 150-300 ppm the sense odor will finally disappear if the content of hydrogen sulfide in the air excess ppm. Because of that it is not possible to decide if a location is dangerous because of hydrogen sulfide.

The hygienic limit value for hydrogen sulfide is 10 ppm:

  • By 10-50 ppm occurs a light eye irritation
  • ​By 50-100 more serious eye damages and difficulty breathing after 1 hour in the contaminated air.
  • ​By 100-200 ppm occurs cough and eye trouble, as after 10-20 minutes is accompanied by dizziness, and with exposure for the gas in more hours can the death occur.
  • ​By 500-1000 ppm occurs fast unconsciousness, pulmonary edema, and death.

The acute toxicity of hydrogen sulfide is due to local attacks on tissues, primarily eyes and lungs, and an inhibition of blood’s ability to transport oxygen. Hydrogen sulfide is also a flammable gas which, when mixed with air, is explosive at concentrations between 4 and 46% by volume.​

What customers says about the professional air purification for pump wells HS Purifier

”At Svendborg wasterwater we carried out a test with JIMCO’s HS Purifier and showed that it effectively reduces H2S.”

Thomas Egel - Technician

Svendborg Wasterwater​

​”We use JIMCO’s HS Purifier in several of our pump wells to reduce odor to the surroundings and to neutralize hydrogen sulfide. We have been working with JIMCO for more than 10 years.”

Bjarni Hansen - Operations Manager

Langelands Forsyning

”We brought 5 HS-Purifiers from JIMCO. We mounted 4 and had good results with the 3 of them. The last one did not show immediate results, but after 14 days of operating there was a noticeable difference in the well. We are very satisfied with the JIMCO HS-Purifiers”

Alex Olsen - Teamleader

​technical data

The HS Purifier solution is connected to a 230 V power supply and is mounted vertical in an Ø110 PVC tube with the ventilator on top. The Ø110 tube ends in the pump well and the ozone will go through the tube into the pump pit.
