CIE Srl - Waste Water Treatment and Zero Liquid Discharge Plants for Lines for degreasing, pickling, chromating or Cr-free of light alloy castings

D.I. UNITS

Purification plants with Ion Exchange (I.X.) technology, able to deliver demineralized water with low salt concentration and conductivity to be used within process or as a cycle of rinse waters.

PUR-ALL

Waste water treatment plants for metal finishing (aluminum and steel) wastes treatment.

OXIPUR

Units with chromatographic acid retardation resins for treatment and reuse of anodizing or acid pickling baths by removal of dissolved metal salts.

CHEMGUARD

Instrument control system for metal finishing baths (degreasing, pickling, chromating, phosphating, etc.) and dosing of the required chemicals.

RINSEGUARD

Analysis and maintenance of contaminant concentrations in rinses from degreasing, pickling, chromate, phosphate, etc. through conductivity, pH measurements and automatic introduction of fresh water.

REVERSE OSMOSIS

Unit for separation of soluble salts from water in order to obtain water with low conductivity.

EVAPORATION

Spent solution concentrators by evaporation of water and its condensation as a distillate.

ZERO LIQUID DISCHARGE

Highly sophisticated plants for purification and total reuse of water coming from metal treatment, using a combination of technologies such as: chemical-physical purification, sand and charcoal filtration, UF, RO and Evaporation.

ZERO ZERO

Zero Liquid Discharge units equipped with cogeneration system for the reduction of evaporation energy costs.

PHOENIX

Catalytic process for caustic soda recovering by spent Die Cleaning Solutions.

MECHANICAL FILTRATION

Filtration is the general unitary operation able to remove solid particles from a liquid.

MEMBRANE FILTRATION

Units for the membrane filtration of water containing suspended solids and oily substances.
