Dear Tung,
Would you be able to provide the dates for following events:
Chemical washing of RO membranes for recent 4 washings (or those carried out within recent 2 years)
They did not make any note when chemical washing is done.
The recent RO membrane replacement
(I remember Dama purchased new membranes end of last year, did they carry out any replacement?)
No, they have yet carry out the replacement. They will replace the membrane on the next shutdown
What are the monitoring parameters to decide when to carry out chemical washing?
If usual permeate flow rate is off by 10lpm chemical washing will be carry out
I will look more detailed into the data and graphs for further comments with the info given.
Thank you.
Regards,
Guo Jing
Tung,
亲爱的唐：
Would you be able to provide the dates for following events:
你能提供下列活动的日期吗 ：
Chemical washing of RO membranes for recent 4 washings (or those carried out within recent 2 years)
They did not make any note when chemical washing is done.
RO膜最近4次洗膜日期（或在最近2年内进行的洗膜的日期）。
他们在清洗化学品时没有做任何记录。
The recent RO membrane replacement
(I remember Dama purchased new membranes end of last year, did they carry out any replacement?)
No, they have yet carry out the replacement. They will replace the membrane on the next shutdown
最近的RO膜置换日期 （我记得去年底达玛买了新的薄膜，他们有没有进行任何更换？） 不，他们还在更换。他们将在下次关闭时更换薄膜
What are the monitoring parameters to decide when to carry out chemical washing?
If usual permeate flow rate is off by 10lpm chemical washing will be carry out
有哪些监测参数来决定何时进行化学清洗？ 通常渗透流速在10lpm以下，将进行化学清洗
I will look more detailed into the data and graphs for further comments with the info given.
我将更详细地查看数据和图表，以获得更多的评论和信息。
Thank you.
Regards,
Guo Jing

董建华先生:你能提供最近4次清洗的RO膜化学清洗日期吗?(或最近2年内的清洗日期)最近的RO膜更换(我记得Dama在去年年底购买了新的膜，他们进行了更换吗?)没有，他们还没有进行更换。他们会在下次关机时更换膜，什么是监测参数来决定什么时候进行化学清洗?如果正常的渗透流量在10lpm之前关闭，将进行化学清洗，我将更详细地查看数据和图表，以得到进一步的意见和信息。谢谢你！问候,郭靖
