The final output is always as we desire because it goes through many stages of improvisation. Before any RO Membrane is out for final packaging, it is tested for its accurate performance. We also re-check them in-case of any issue arises during its usage. The product goes through the stages of pressure test, filtration check and other mandatory processes. We have separate labs for dry and wet membranes. The wet membranes need to pass a mandatory check that we conduct. It is a standard test. Some other tests that we have come up with keep our products updated and satisfy us, too, with the quality that we aim to provide. The membranes failing the test are segregated to study the issues which might have caused an error.
