Proposals for consideration:1. Reverse osmosis/Ultra-filtration - resource of membrane is defined by the volume of passing water and an electro-magnet (e/m) valve will be to close the water when volume of water was passed. If there is no water - call a service to replace cartridges. E/m valve required on all devices.
2. Need to install the adjustment of total dissolved solids (TDS) for reverse osmosis system. It can be set at the factory, but can be adjusted as a scale valve bypass. The amount of salt is determined by the TDS-meter - threshold value (not less than 100mg/l).
3. It is proposed to set the quality of water for initial installations (3 options of total volume: 1 – bad water - 1000L, 2 – average water – 3000L, 3 – good water - 5000L) and to calculate the time for replacement cartridges.
4. To develop the algorithm of operation of the monitor with regard to suggested water quality (3 variants).
5. For entrance to service mode need to hold the button for at least 4 seconds on the panel.
6. Our suggestion - Exclude KDF filter (It's expensive and working badly).
7. Hide a tube of submission of the source water, the output of filtered water, drain pipe into a pipe or duct.
8. Send to us the "Service Manual for filter" and technical details on UV systems and replacement cartridges.
9. Set the colour display on the device.
Questions:
1. How to determine the difference of pressure of the RR for making decision on replacement, if the pressure drop across the filter more than 1,5 Bar?
2. How are working a back wash of the membrane cartridge for UF?
3. The new generation of UV-lamps. Is it possible to make in according to our drawings?
4. Is it possible to make the filters FS (housing and mesh 20-mg) pre-filter mesh strainer in according to our drawings?
5. Is there a sample of cartridge 0,1mc and to show a composition and price. Compare with analogue of Harmsco Corp. (USA) – 0,3mc

太多了，翻译一段吧：

反向渗透膜/超滤 -膜资源视通过的水量以及水量通过时靠近水的电子阀（e/m）而定。如果没有水流出-就应拨打服务电话，请人更换滤芯。所有装置上都需要电磁阀。

2. 需要安装调整的总溶解固体(TDS)反渗透系统。它可以设置在工厂,但是可以调整比例阀旁路。盐的数量取决于TDS-meter -阈值(不少于100毫克/升）。
