Claim 13:
14. The algae harvesting method of claim 11, wherein the permeate suction source comprises:
the siphon tank containing permeate;
a vent from the siphon tank to the atmosphere;
a fluid connection between the permeate valve and a point below a permeate level in the siphon tank, such that a siphon is generated; and
a permeate pump configured to withdraw permeate from the siphon tank;
wherein the permeate suction source is configured to maintain the permeate level in the siphon tank by measuring the permeate level in the siphon tank and varying a flow rate of the permeate pump, such that a negative suction pressure is maintained at the permeate valve.
