Ebrahim,
There are some good suggestions here already.
Chlorine will certainly slow down or kill off algae with the right dosage.
Other suggestions
If you can stop sunlight entering the product tank you will stop the growth of all algae. Shading will slow them down.
You don't say if the problem is due to attached or planktonic (floating) species or but I assume you will have low water residence time in the product tank so probably attached algae (filaments) as the planktonic species will be washed out. So a good scrub of the walls and floor along withthe chlorine if you have attached forms.
Cheers
