Appl. No.:

11/026137

Inventors:

Harold Diamond - Alpine NJ, US
Joshua Schwarz - Wesley Hills NY, US

Assignee:

Diamond Chemical Company, Inc. - East Rutherford NJ

International Classification:

C11D 17/06
C11D 3/06
C11D 3/10
C11D 3/395

US Classification:

510276, 510309, 510375, 510378, 510506, 510509, 510510, 510108

Abstract:

Cleaning compositions functioning in a unique manner are described. These new compositions provide improved cleaning efficacy for all types of surfaces. In addition, in textile laundry applications these compositions provide superior cleaning efficacy for all types and colors of fabrics, as well as extending the range and types of stains and dirt that commonly can be treated by present day commercial laundry compositions.

Filed:

Nov 16, 1992

Appl. No.:

7/976816

Inventors:

Thaddeus J. Kaniecki - Pompton Plains NJ
Harold Diamond - Fort Lee NJ
Larry Rotter - Andover NJ
Rudolph N. Vermes - Randolph NJ

Assignee:

Diamond Chemical Company, Inc. - Lyndhurst NJ

International Classification:

C02F 152

US Classification:

210704

Abstract:

The invention pertains to the purification of commercial, industrial and institutional waste streams in order to bring them into dischargeable compliance with environmental standards. The invention provides a system for removing contaminants, such as fats, oils and grease (FOGs) and total petroleum hydrocarbons (TPHs), from waste effluents on an essentially continuous basis. During the treatment process, the FOGs and TPHs disposed within the textiles to be cleaned are treated with an alkaline, pH- or acid-sensitive detergent, causing their emulsification. The effluent waste stream is then treated by removing the solids and particulates. The alkaline emulsion is broken up by acidification of the wastewater, thereby releasing and dispersing the FOGs and TPHs. The FOGs and TPHs in the broken-up and dissolved emulsion are agglomerated by the introduction of an organic, cationic polymer. The waste stream is then fed to a separation station, where the oils are adsorbed on an appropriate surface, such as a plate or lipophilic media pack.

International Classification:

B01D 1704

US Classification:

210708

Abstract:

In accordance with the present invention, there is provided a system for treating commercial, industrial and institutional effluents to remove contaminants such as: fats, oils and greases, (FOGs) from the waste water. The system generally features a continuous processing treatment of the effluent, but can also be adapted on a small scale to a batch procedure. The system comprises the feeding of an emulsified waste stream to a first screening station, where solid matter and large particulates are removed. The FOGs in the waste stream are initially emulsified during the laundering or cleaning process by an alkaline detergent. The alkaline, emulsified waste stream is then fed to a first stage of a pH adjustment station. Here, the emulsified FOGs begin the process of being released and dispersed within the fluid, through the downward adjustment of the pH, i. e. by treating the effluent with acid.
