12) Remarks

13) Size of the batch can only be determined after we get results from you of your Pilot Plant trials, or we conduct the trials in our Pilot Plant. You will have to give us 250 litres of slurry for trials. We shall be charging a nominal sum of Rs. 9000/- towards cost of trials, which will be refunded in case we receive order. Also, please note that your materials should be sent to our factory at your cost and the same must be collected from our works after trial is over within a week. In case materials are not collected we shall arrange to send the same to you at your cost.

Please fill up the answers to all the questions. In any information asked for is not available, you should mention "Not Available" in the space provided for the answer. Besides, the information asked for, any other information you feel is relevant may also be furnished. This will enable us to design a most efficient Filter.

Note: If space provided for answering any question is not adequate, please reply in separate sheet and attach.
