Wastewater Treatment Emission Control

Wastewater Treatment Emission Control .Chemteq supply filter replacement indicators for hydrogen sulfide ammonia and mercaptans

Wastewater Treatment Emission Control.

Sewage odor is often the number one complaint related to wastewater treatment and waterworks facilities which is mainly due to hydrogen sulfide gas.

Using Chemteq filter’s replacement indicator on the outlet of filter or carbon absorber alerts the user when filter or carbon absorber is saturated .

Our filter replacement indicators, not only ensures the health and well being of the wastewater treatment staff.  But also ensures that residents around the plant are breathing odor free air.

Filter change Indicators for drum type filters

We make filter change indicators BTI  for ammonia, hydrogen sulfide and mercaptans.

BTI2  for ammonia, hydrogen sulfide and mercaptans,  BTI3   for ammonia, hydrogen sulfide and mercaptans.

Breakthrough indicators inline inlet BTI inline for ammonia, hydrogen sulfide and mercaptans.

Filter change indicator stickers for manhole filters

Sewer manhole filter change indicator for hydrogen sulfide. Filters end of service life indicators for hydrogen sulfide.

We also make three different sizes of filters with end of service life indicators for hydrogen sulfide and ammonia.

Custom cut colorimetric indicators are available for wide range of chemicals including hydrogen sulfide.

Our indicators have shelf life range between one year and two years, plus service life range between one year and two years.

Sunlight has no effect on the hydrogen sulfide indicators, and they are waterproof. Available in one side and two side indicators and you can observe color change from both sides
