Abstract
Systems for cleaning waste water described herein include an integrated and portable skid having a clarifier and a microfiltration tank. The microfiltration tank includes a plate with a plurality of microfilters, the microfilters each including a sock filter that hangs down into the microfiltration tank from the plate. The system may periodically clean the microfilters by opening a backwash valve below the microfiltration plate, reversing water flow through the microfilters based on a negative pressure drop, separating particulate from the microfilter walls.
Claims20
A system for cleaning waste water, the system including:
- a base;
- a clarifier tank positioned on the base;
- a microfiltration tank positioned on the base, the microfiltration tank including a microfiltration plate that includes a plurality of microfilters, wherein the microfiltration tank includes a plurality of valves including:
- a clean water output above the plate in the microfiltration tank;
- an input below the plate that receives a solution for cleaning from the clarifier or a mixer into the microfiltration tank;
- and
- a backwash valve that automatically opens to create a pressure drop of at least 4 PSI between the output and the backwash valve, causing clean water to flow back through the microfilters.
A compact water cleaning skid including:
- a base having dimensions of less than 7 feet wide and 7 feet deep, wherein at least the following components are affixed to the base:
- a clarifier tank that includes both a solution holding tank and a clarifier with a weir;
- a backwash holding tank;
- a control center;
- and
- a microfiltration tank including a microfiltration plate having a plurality of sock microfilters, the microfiltration tank including a clean water output above the microfiltration plate and a backwash valve below the microfiltration plate, wherein the backwash valve is actuated by the control center to create a pressure drop and cause cleaned water to flow back through the plurality of sock microfilters.
A water cleaning skid including:
- a microfiltration plate;
- a clean solution ouput above the microfiltration plate;
- a dirty solution input below the microfiltration plate;
- a backwash valve below the microfiltration plate;
- and
- actuation circuitry that causes the backwash valve to open, creating a pressure drop that causes clean solution to backflow through the microfiltration plate.
