conducted by

injecting ozone at different concentra- tion levels for ozonolysis. There was reduction in oil and grease & COD, but there was increase in hard-ness. The treatment was effective but costly. Samples were also treated with 1,4 Dioxan. Result showed that there were no reduction in oil & grease. Study was conducted with commercial emulsi –fier wherein the reduction in oil & grease was obser-ved but the process was tedious &

* Correspondence has been done to procure PTT yarn from various suppliers. Request in this regard has been made to supplier of `Corterra’ fibres of Shell Chemical Co. Similarly, supplier of Triexta’ fibers of Dupont Co. has been approached. We are

awaiting their response.

* Since no response was received from M/s Shell Co., correspondence has been done with Product Marketing Manager of M/s DuPont India. He has arranged 10 kg of DuPont Sorona (PTT) fiber from their agent in Korea, which will be received by 1^st week of February.

Under this project, an HTHP beaker dyeing machine is required. For this, quotations from two companies have been received.
