## Abstract

This Invention Patent application provides a comprehensive program for control of organic and inorganic contaminants from paper production processes and other potentially pollutant industries through the integrated action of three continuous treatment systems, referenced herein as “3WAY”, with a first system aimed at the treatment of process waters for reuse, more specifically “white or clarified water” present in the “wet end” of paper and cellulose machines, allied to a second system based on the use of an adsorbent clay mix equipment that enables treatment of the cellulose pulp in previous phases of the process up to the machine circuit, in addition to a third system that carries out the cleaning of contaminant deposits present in clothing (felts and wires) or other machine parts through application of a heated and pressurized cleaning solution with a high detergency power.

## Claims

### Claim 1

“HYBRID SYSTEM FOR CONTAMINANTS CONTROL OF INDUSTRIAL PROCESS” comprising three integrally-controlled contaminant control systems, comprising a clothing and machine parts utilized in clothing treatment cleaning system including a thermal injector pump for injecting material for cleaning contaminants from the clothing and machine parts, a process water treatment system including an oxidative reactor for removing contaminants from water utilized in the cleaning system, and a cellulosic pulp treatment system including a shear chamber, provided with adsorbent clay, for treating cellulosic pulp from said clothing and machine parts.

### Claim 2 (depends on 1)

“HYBRID SYSTEM FOR CONTAMINANTS CONTROL OF INDUSTRIAL PROCESS”, according to claim 1, wherein said oxidative reactor includes a reagent capable of degrading organic load of the water.

### Claim 3 (depends on 1)

“HYBRID SYSTEM FOR CONTAMINANTS CONTROL OF INDUSTRIAL PROCESS”, according to claim 1, wherein the shear chamber provided clay comprises bentonite clay and a hydrotalcite clay.

### Claim 4 (depends on 1)

“HYBRID SYSTEM FOR CONTAMINANTS CONTROL OF INDUSTRIAL PROCESS”, according to claim 1, wherein the clothing and machine parts treatment cleaning system includes thermodynamic equipment comprising the thermal injector pump and further comprising a diffuser that combines fresh water, steam and products chemicals capable of producing a heated and pressurized chemical solution at pressures between 7 and 35 kgf/cm and temperatures between 70 and 99° C.
