Treatment of waste water of a conference center in Jamaica 1

[munich]

A conference center for about 10,000 visitors will be built near the city of Kingston, Jamaica (Old Harbour). Are there any collegues, which might be able to come up with design hints, tips, comments etc.
I would be grateful to share opinions and to listen to advices.

My background: I am a chemical engineer from Germany, living and working in Jamaica since about 15 years. Since there is only a little bit of chemical industry in Jamaica I am working in the environment field with emphasis on small wastewater and sewage treatment plants.
Looking forward to comments
Cheers

If available land can be found, nothing is more cost effective than sewage treatment lagoons. Coupled with a wetland marsh, they can provide tertiary treatment.

If you are going to put in UF/RO system, a membrane bioreactor may be a good solution. The benefits to the MBR is that you replace the clarification with membrane separation. Then you don't have to worry about maintaining good settling sludge, so you can increase your biosolids concentration in the activated sludge process and increase the capacity or biological treatment of your system. (probably need to add some more aeration) and you get rid of the activated carbon and ozonation before the RO.

Munich,

Try Danny Hibbert at Omni Services (876-929-5568 or 876-926-6565). They have installed quite a few small treatment systems on the north coast.

I'm not convinced a membrane biological reator would cope with the huge changes in flow and load you would expect in the discharge from a conference centre. My experience of them has shown they don't handle changes very well.

This is a domestic wastewater management problem as such could be dealt with by providing enough detention time, then filtration and aeration before subsequent disposal. There also lots of soft wares to help you in the modelling and design
