Abstract
A system for reconditioning contaminated water includes a plurality of filter tanks, each filter tank configured to hold a media mixture comprising media particles to which contaminants adhere when the contaminated water is pumped through the filter tanks and a feed water pump to pump the contaminated water through the plurality of filter tanks. The plurality of filter tanks are configured to form a multistage filter system for filtering the contaminated water at different contaminant particle sizes, and the feed water pump pumps the contaminated water through the multistage filter system in a continuous manner during a normal filtering mode.
Claims18
A system for reconditioning contaminated water, the system comprising:
- a transportable skid;
- treatment equipment mounted on the transportable skid, wherein the treatment equipment is configured for treating the contaminated water, and wherein the treatment equipment consists of:
- a plurality of filter tanks, each filter tank containing a media mixture comprising media particles to which contaminants adhere when the contaminated water is pumped through the filter tanks;
- and
- an oxidant chemical pump to inject an oxidant into the contaminated water before it is pumped into the filter tanks, the oxidant serving to interact chemically with contaminants in the contaminated water to cause the contaminants to adhere to the media particles in the filter tanks;
- water transporting equipment mounted on the transportable skid, wherein the water transporting equipment comprises an input pipe, a filtered water output pipe, and a feed water pump configured to pump the contaminated water through the plurality of filter tanks,
- wherein the plurality of filter tanks are configured to form a multistage filter system for filtering the contaminated water at different contaminant particle sizes, and
- wherein the feed water pump pumps the contaminated water through the multistage filter system in a continuous manner during a normal filtering mode.
A water treatment system to recondition contaminated water in oil and gas fields, the water treatment system comprising:
- a skid configured to be a mounting frame that permits the system to be transportable;
- treatment equipment mounted on the skid;
- and
- water transporting equipment mounted on the skid,
- wherein the treatment equipment is configured for treating the contaminated water, and wherein the treatment equipment consists of:
- four filter tanks configured to be a multi-stage filter system comprising media mixtures serving as filtering particles to which contaminants in the contaminated water will adhere;
- and
- an oxidant chemical pump to inject an oxidant into the contaminated water before it is pumped into the multi-stage system, the oxidant chemically interacting with contaminants in the contaminated water to permit the contaminants to adhere to the filtering particles in the media mixtures in the multi-stage filter system;
- wherein the water transporting equipment is configured for transporting the contaminated water, and wherein the water transporting equipment comprises:
- a contaminated water input pipe to be connected to a source of contaminated water to be filtered and reconditioned;
- a unit pump mounted on the skid, the unit pump configured to pump contaminated water received via the contaminated water input pipe through the multi-stage filter system during a normal filtering mode;
- and
- a filtered water output pipe through which filtered and decontaminated water exiting from the multistage filter exits the water treatment system,
- wherein, during the normal filtering mode, the unit pump continuously pumps input contaminated water through the multi-stage filter system.
