Pilot Testing for Wastewater Treatment

Industrial wastewater: a "mandatory" step

The need for pilot units is often recognized by engineers and contractors working with civil wastewater treatment plants. Even more so, the need is noted with professionals working for industrial wastewater treatment: in this case, in fact, the quality of the effluent changes considerably from plant to plant and there is no precise sequence of treatments (primary, secondary, tertiary). It is therefore essential to understand in advance the amount of suspended solids, phosphorus and nitrogen, and the values of BOD and COD.

Determining the flow rate is also a key factor in getting off to the right start with the project: what can be easily detected from the pilot units. In addition, industrial wastewater also has all the more reason for preliminary pilot testing because of its complexity (e.g., abnormal sludge, need for chemicals, etc.).

MITA units for filtration and biological treatment

MITA Water Technologies, aware of these needs, is expanding its fleet of pilot units for water treatment.

Currently, we can offer pilot tests to the customer through filtration and biological oxidation units.

• MITA’s pilot filtration units are free-fiber cloth filters (type TF2): they are useful for tertiary filtration, i.e., the finishing part of the effluent before discharge into water bodies or reuse. Free fiber allows depth filtration, which is more efficient than surface filtration for the same useful surface area.
• Testing for biological treatment, on the other hand, takes place through Biorulli® biological oxidation systems (such as type M 115): simple secondary treatment solutions by means of plastic biodiscs, immersed in the effluent, on which the flora of aerobic bacteria useful for biodegradation of the organic matter develops.
