Process Description:

The process will be of low operating costs. The procedure consists of pre-treatment, primary sedimentation, biological treatment by means of an anaerobic process of bio-disks and secondary sedimentation.

Sludge is treated through anaerobic cold stabilization and subsequent drying. The plant includes an operating building and a control one.

The project also includes the design of the following elements:

• Sand filtering and filtered pumping from the secondary treatment.
• Flocculation with dosage of aluminum chloride.
• Automatic sifting under 500 um.
• Micro-filtration with polypropylene membranes for particles over 0,001 μ m.
• Reverse osmosis with cellulose acetate membranes for particles over 0,001 μm.
• Disinfection with sodium hypochlorite.
• Pumping and distribution to the Irrigation Community (902 m FD f 300).
