Why do we need filters?
Filters are sometimes needed to remove the “precipitated” contaminant (iron, for example), or to remove an injected chemical and its by-products after it has done its work. Chlorine, for example, can create some very undesirable spin-off chemicals.
What is a solution tank?
A solution tank to hold the solution you're going to inject into your water. A pump to feed the solution into your water line. A simple tee connection to provide an entry port for the solution into your water line.
Is chemical feeder system a guarantee?
Below is a brief summary of problems that you might treat with a chemical feeder system. This is not an exhaustive list and it is not a performance guarantee. Here, as with any water treatment strategy, results can depend on many variables. It's often best to get advice before ordering.
Can a Stenner pump feed hydrogen peroxide?
And equipment purchased for one purpose can be easily converted to another. The high quality Stenner peristaltic pump can be used to feed chlor ine or soda ash, for example , but is also capable of feeding hydrogen peroxide without losing its prime.
