closed loop recycle system

closed loop recycle system

closed loop recycle system

(OP)
Hi Everyone,

I am a first time poster. I am trying to design a small closed system recycle loop for the treatment of wastewater containing mono/di valent metal cations and some soft marine growth. I was thinking of introducing the influent into a settling chamber. After sitting for some time, it would be directed to the top of a sand filter. For obvious reasons, I would replace the sand with clinoptilolite (a form of naturally occurring zeolite) capable of removing the cations. The effluent would then be directed to a storage container for wash re-use. I know their will be some maintenance issues associated with the settling chamber and clinoptilolite substituted sand filter. Does anyone have any experience with something similar? Any general observations or suggestions would be greatly appreciated.

Some other technical info:

1) Since the system will be used to collect and treat wastewater generated during marina washing processes, it does not need to be continuous system. On active days it may need to treat as much 500 gallons a day. If that water could be available in the storage container every morning (for use by a pressure washer), that would be satisfactory.

2) My greatest concern is fouling of the system. Since I have very little familiarity with this issue, I am trying to predict any foreseeable problems that may arise and remedy them in the design.

3) The system needs to be as low cost and low maintenance as possible.

4) The recycled wastewater only needs to be clean enough to perform the cleaning process again. It will not be used for drinking. Probably something equivalent to gray water. It should not clog the pressure washer.

Thank you for the help,
RM
 

RE: closed loop recycle system

1) filtration system will be solution
2) Please test your sytem via your pilot scale before go to real invesment, you must know by collect information of inlet concentration & load vary
3) the full closed loop will have high operation and maintenance cost if bio-growth too high
4) take 60% as closed loop & 40 % as open chamber or vice versa

5) activated charcaol + sand filteration always resonable economic and hydralically handle by simple sytem
6) Try to optimize the gravity flow for separation brfore force via pump
