The current Equity multiplier stands at 97.48%; If you observe the above calculation, you will notice that a simple ROE calculation would not have given you a clear picture of the performance of the company. Webcellulose membrane. Stable process pressures and flow conditions indicate absence of plugging and suitability of cassette design. No Protein Loss Samples of composite permeate from each process run were analyzed for protein using the biuret method. No protein loss was detected in the permeate, indicating greater than 99.9% protein yield.
