A method of removing silicone oils from waste water generated by a silicones manufacturing plant including the step of centrifuging the waste water to concentrate silicone oil contaminated solids while removing the silicone oils. The silicone oil contaminated solids are then dried in a continuously mixed sludge dryer to remove more silicone oils from the sludge to form a sludge product which comprises at least 10% water and a low silicone oil concentration.

System for removing silicone oil from waste water treatment plant sludge

An on-line sparging sampling system and method sparges polar and non-polar volatile organic compounds from aqueous discharge. The system comprises a network of tubular members that are interconnected to each other to define a fluid passage, in which the network of tubular members comprises an inlet for influent aqueous discharge into the network of tubular members and an outlet for discharge of aqueous discharge from the on-line sparging sampling and monitoring system; a sparger disposed in the network of tubular members, in which the sparger is disposed between the inlet and the outlet of the aqueous discharge so that aqueous discharge flows by the sparger, the sparger providing inert non-reactive gas to the on-line sparging sampling and monitoring system; and at least one analytic device connected to the on-line sparging sampling and monitoring system for analyzing volatile organic compounds in the aqueous discharge. The aqueous discharge forms an aqueous discharge portion and a headspace during flow through the network of tubular members. The sparger provides the inert non-reactive gas to flow through the aqueous discharge portion. The inert non-reactive gas partitions volatile organic compounds from the aqueous discharge portion to the headspace. Thus, polar and non-polar volatile organic compounds can be analyzed by the at least one analytic device.

On-line sparging sampling and monitoring systems and methods

A headspace sampling system monitors materials in wastewater. The headspace sampling system comprises a sample receptacle that can contain a wastewater sample; a sparger chamber vapor column; a sample receptacle cover assembly that connects the sparger chamber vapor column to the sample receptacle; a sparger tube; at least one sensing device; and at least one analytic device. The sparger tube and the sample receptacle define a headspace. The sparger chamber vapor column is in communication with the sample receptacle and is closed by a sparger chamber vapor column cover at a second end that is opposed to the sample receptacle. The sparger tube extends into the sample receptacle and the wastewater sample in the sample receptacle. The sparger tube is connected to a source of inert gas at a first end opposed to the sample receptacle and comprises a dispersion device at an end opposed to the first end. The sensing device is disposed in the headspace sampling system in the headspace. The analytic device in communication with the least one sensing device. Inert gas can flow through the sparger tube into the wastewater sample to separate materials from the wastewater, the sparged materials entering the headspace of the headspace sampling system. The sparged materials are sensed by the sensing device thus providing material signal characteristics, which can be analyzed by the analytic device to determine characteristics of the material from the material signal characteristics and provide information about the characteristics of the material.
