Pressurized electro-separation system
View Patent ↗A treatment system for treating a liquid containing contaminants is provided. The system can include a separation apparatus, an oxidation reactor and a power supply. The separation apparatus can include: a housing capable of maintaining a pressure of 50 psi or greater in an interior space; an inlet; an outlet; and an electrode assembly provided in the housing. The oxidation reactor can include: a housing defining an interior space; an inlet oriented to induce swirling in an incoming flow of liquid in the interior space of the housing, the inlet connected to the outlet of the separation apparatus; an ozone port leading into the housing; an outlet; and a conduit connected at a bottom end to the outlet and extending vertically in the housing to an opening at a top end. The power supply operative to supply a voltage to the first and second electrical conductors of the separation apparatus.
1. A method comprising:
providing a separation apparatus comprising:
a housing defining an interior space; and
an electrode assembly provided in the interior space, the electrode assembly having a plurality of electrode plates;
routing liquid containing contaminants into the interior space of the housing of the separation apparatus;
increasing the pressure in the interior space of the housing to between 50 psi and 80 psi and supplying a voltage across adjacent electrode plates; and
supplying the voltage for a period of time while maintaining the pressure in the liquid between 50 psi and 80 psi to allow the contaminants in the liquid to destabilize.
2. The method of claim 1 further comprising providing an autowash assembly in the housing and using the autowash assembly to spray a cleaning liquid between adjacent electrode plates of the electrode assembly, wherein the autowash assembly comprises a plurality of spray nozzles operative to direct a flow of liquid from the autowash assembly into gaps formed between adjacent electrode plates of the electrode assembly.
3. The method of claim 2 wherein the autowash assembly is used when the housing contains liquid to be treated.
4. The method of claim 2 wherein the autowash assembly is used when the housing is drained of liquid to be treated.
