System and method for treatment of wastewater via enhanced electroflotation

A method for treating wastewater involves electrolyzing a stream of seawater and wastewater mix within one or more electrolytic cells mounted outside a batch tank. The electrolyzed stream is piped to a quelling chamber which is mounted above the batch tank. A diluted polymer solution is injected at upstream of an in-line mixer piping into the quelling chamber substantially concurrently with the electrolyzed stream. The polymer solution and the electrolyzed stream are dispersed as a fine shower over residual seawater and wastewater in the batch tank. The polymer solution facilitates flocculation of the suspended solid particles and creates a distinct buoyant layer of flocculated solid particles attached with micro bubbles. A substantially clarified effluent is separated from the flocculated layer and neutralized prior to discharge. The flocculated layer is pumped from the batch tank to a dewatering system where entrained solids are compacted to a desired level. A centrate generated during the solids/sludge dewatering step is recirculated to the batch tank prior to addition of seawater during a subsequent treatment cycle as a supplement to the seawater.

The conveying system may include a series of rollers to provide a path for a container to pass through the wash system and the drying system. The wash system and drying system may be housed in a containment structure, which may be mounted to a trailer thereby allowing the container washing system to be portable. The wash system may include one or more water jets for spraying water at a container carried by the conveying system, and the drying system may include one or more air nozzles for directing moving air at the container carried by the conveying system. The conveying system may be motorized to automatically convey the container through the wash system and the drying system. The water may be reclaimed, filtered, and recirculated through the wash system.

Water treatment for removing PFAS

An above-ground low-energy method of dewatering highly contaminated waste e.g. leachate contaminated with at least a first group of contaminants and PFAS is described. The method comprises the step of removing the PFAS before removing the first group of contaminants. The removal of PFAS is undertaken by actively aerating the contaminated waste comprising PFAS to produce a waste stream comprising a concentration of PFAS and a liquid stream having at least some of the first group of contaminants. The one or more liquid streams are separated from the waste streams so as to dewater the contaminated waste. Optionally, the liquid streams are treated to remove the first group of contaminants.
