About ECA Disinfectant

Information about what Electrochemical Activation Technology is and how it's outstanding sanitation capability can be used in real-world scenarios.

Introduction

A few years ago, we began work on designing an automated production unit that uses non-toxic liquid for water disinfection. This piece of equipment was designed to be capable of increasing and decreasing pH as well as controlling odours.

After years of research and development, our product is now a validified and proven concept. The resulting product is Electrochemically Activated (ECA) Disinfectant. This product is kind to the environment and eliminates the necessity for transporting and storing dangerous chemicals. ECA Process Water lowers cost, reduces carbon emissions and eliminates some risks by letting you maintain control of production. ECA Disinfectant doesn't require specialist equipment or maintenance.

The system typically uses what would otherwise be waste process water and electrochemically activates it.

Definitions of electrochemical activation

Electrochemical activation is a technology to generate metastable substances with strong oxidizing and reducing properties. This is used in various technological processes instead of chemically stable reagents.

As a physical-chemical process, electrochemical activation is a combination of electro-chemical and electro-physical effects on water. It does this with ions and molecules of dissolved substances that are carried out in conditions of minimum heat in the space charge region at a surface of an electrode (either anode or cathode) of an electrochemical system under non-equilibrium charge transfer across the border of "electrode-electrolyte" electrons.

ECA is Environmentally Sustainable

ECA uses salt solutions which contain alkali and alkali-earth metals and mixes them with water using electricity. This results in pure, low-mineralized ECA solutions. Low-mineralized ECA solutions self-degrade over time to their original state without formation of harmful and toxic by-products

Cost efficiency

ECA is cost efficient due to its use of affordable and inexpensive reagents (salt and water) in electrolysis.

Unison ECA devices generate reagents in any quantity so there is no need to deliver, store and securely maintain standard reagents.

Case Study: Hudson Valley WWTP

The Unison ECA unit was first deployed in coordination with the New York State Department of Environmental Conservation. It was piloted at a large municipally owned Wastewater Treatment Plant (WWTP) on the Hudson River.

New York has some of the most stringent wastewater discharge permit standards in the world, but the Unison ECA Unit easily met permit standards and delivered demonstrable cost savings. The facility uses a sodium hypochlorite disinfection system comprising of two 5,000 US gallon (~18,927L) storage tanks. Permit samples are collected daily and cannot contain more than 200 colonies of faecal coliform (a disinfection efficacy indicator), nor have a chlorine residual (by-product) in excess of 0.75mg/L. In order to meet its permit standard, the facility uses approximately 10,000 US gallons (~37854L) of sodium hypochlorite every two weeks, as well as sodium bisulphate to dechlorinate discharge water in order to meet chlorine residual thresholds.
