The present invention provides novel forms of atorvastatin designated Forms VI, VIII, IX, X, XI and XII and novel processes for their preparation as well as processes for preparing atorvastatin Forms I, II, IV, V and amorphous atorvastatin. The bioreactor tank receives recycled wastewater feed from a recycle tank and discharges via an overflow outlet treated wastewater and microbial consortia particles to a bioselector. During operation the resonance tube provides a pulsating output which is directed into the fuel nozzle. In one example, each cell includes four charge storage locations, each for storing one bit of data.
