Abstract
The present invention involves an improved integrated reactor and solids settler system for solids removal from a water stream. The integration of the rapid mix reactor and the solids settler of the present invention uses an overflow line from the rapid mix reactor to eliminate both the rapid mix reactor level indicator and controller and the flow controller in the solids settler clarified water outlet. The proposed design is simple, cost effective, and eliminates the possibility of unnecessary downstream unit shutdowns.
Claims18
An apparatus for treating and removing solids from grey water generated in a high pressure, high temperature gasification system, the apparatus comprising:
- a reactor comprising a plurality of reactor inlet means, a mixing means, and a plurality of overflow lines;
- a settler comprising a plurality of settler inlet means, a coagulation chamber, a sludge outlet means, and a plurality of liquid outlet means;
- and
- a transfer conduit connecting the plurality of overflow lines and the plurality of settler inlet means,
- wherein the plurality of overflow lines are located on the side of the reactor where a liquid level in the reactor is to be maintained, and a flow of liquid through the plurality of liquid outlet means is not adjusted so as to control a level of liquid in the reactor.
A method for treating and removing solids from grey water generated in a high pressure, high temperature gasification system, the method comprising:
- supplying a plurality of feeds to a reactor through a plurality of reactor inlet means in the reactor;
- mixing the plurality of feeds within the reactor forming a feed mixture;
- removing the feed mixture from the reactor through a plurality of overflow lines, wherein the plurality of overflow lines are located on the reactor where a feed mixture liquid level in the reactor is to be maintained;
- transferring the feed mixture to a settler, wherein the feed mixture is introduced into a coagulation chamber in the settler through a plurality of settler inlet means;
- allowing solids to settle out of the feed mixture and accumulate in the bottom of the settler, forming clarified water;
- removing the solids from the settler through a sludge outlet means;
- and
- removing the clarified water from the settler through a plurality of liquid outlet means, wherein the flow of clarified water through the plurality of liquid outlet means is not adjusted so as to control the feed mixture liquid level in the reactor.
