StingRay MART EQ-1 Wastewater Processing System

StingRay MART EQ-1 Wastewater Processor 

The StingRay MART EQ-1 Wastewater Processor removes waste from dirty solution in a single step. The EQ-1 System processes waste streams from many industrial or remanufacturing sources.  The water is clarified, and can either be returned to its processing machinery and recycled, or sewered. The encapsulated waste is most often safe for disposal in a landfill. 

The EQ-1 processor is a verified technology tested and qualified by the EPA. It earned the EPA ETV mark signifying technology with tested and verified environmental pollution prevention in metal finishing. The ETV mark provides credible performance data for commercial-ready environmental technologies.

Theory of Operation How it Works

EQ-1 Operations, What it Does

The StingRay MART EQ-1 Wastewater Treatment System recovers Alkaline cleaner and water for reuse. The processor chemically separates and clarifies spent wash solution and encapsulates the waste for disposal. The chemical compound used in the system’s encapsulating process is a non-hazardous product called by its trade name, Magic Dust.

The Upper Reservoir is the Reactor Tank. In use, an operator pumps wastewater into the Reactor Tank where Magic Dust is added and the batch mixed. Unlike conventional wastewater flocculating systems that require multiple steps and the addition of several chemicals, one charge of Magic Dust and a few minutes of mixing complete the EQ-1 separating and encapsulating process. (The exact Magic Dust formulation and dosage is included in your Wastewater Treatability Report furnished by STINGRAY).

During the mixing, chemical reactions and micro-encapsulation occur. Molecules with adsorbed oil, metallic ions, and charged contaminants attach to the Magic Dust to form a mass. The flocculation process encapsulates the waste into a floc. The clarified water retains about 75% of its active chemical. A Sight Tube on the side of the Reactor Tank allows the operator to see when the separation/encapsulation process is complete.

After encapsulation, the operator filters the flocculated waste through a disposable filter paper to collect the waste for disposal. Once filtering is complete, the operator rolls the filter paper with the encapsulated waste like a burrito into a packet. The packets are placed in the drying tray and after several days harden into a solid similar to dry clay or concrete for handling and disposal. 

The clarified solution collects in the Holding Tank. A Submersible Pump in the Holding Tank rinses the Reactor Tank and transfers the clean solution to the Parts Washer reservoir for reuse or to another optional filtering system such as the StingRay MART Final Polishing System for sewer disposal.
