Filtering Water for Industry

The ManagerIn our factory we cool things using water from a local reservoir. The water is pumped along pipes to the factory.

The water must be very clean, otherwise the particles in the water could block the pipes and pumps.

We need to filter the water to remove any solids. How do you think we could do this? Can you help us find the best method?
