Notes de l'éditeur Water Solutions is the water and effluent treatment side of the business at B+W which is managed by Dr John MorganMany companies simply sell a treatment system to a client without proving its effectiveness in treating the problem that they have.At B+W we offer the client our services in checking the sample and possible treatment solutions at laboratory scale first to give us and them more confidence that what we offer will actually work.We also offer the client the opportunity to hire our mobile pilot plant for 1-2 weeks where it can be hooked up to their problematic water system and tested for a longer period of time using various treatment stages. Thus giving added confidence in the treatment effectiveness. Finally we can then be confident in designing, installing and commissioning a water treatment plant which we know will work on the clients water or effluent.Once installed we can then offer them a service and maintenance package to look after the plant on a regular basis each year. We have represented Amazon filters for over 8 years although have had a relationship with them for over 25 years when they first started.We will go on to discuss Amazon in a separate presentation.
