Microclor® OnSite Hypochlorite Generation

Efficiency and Reliability At It's Best

Microclor® On-Site Hypochlorite Generation (OSHG) is the market leading on‐site sodium hypochlorite generator with systems installed worldwide. Microclor® OSHG systems efficiently and reliably generate sodium hypochlorite disinfectant with just salt and power without the inherent risks of gas chlorine or delivered concentrated hypochlorite.

Microclor® OSHG, The Next Generation OSHG

Microclor® OSHG is the next generation OSHG. It was purposefully designed to be safe, reliable and easily maintained. Using only salt and electricity, the Microclor® OSHG brings simplicity and safety to the water disinfection process.

The combined benefits of the following unique features make Microclor® OSHG the most resilient and durable system available today:

Vertical Cell Arrangement
Multiple Cell Configuration
Direct Hydrogen Management
Continuous Process Control
Full-Wave DC Power
Compact Cell Design
High-Velocity Electrolyte Circulation

Safe. Sound. Clean and Green.

As concerns mount and regulations change regarding the safety and security of using chlorine gas for water disinfection, many utilities are choosing sodium hypochlorite (bleach) as a safer disinfection alternative. Once the decision to convert to a safer alternative has been made the question remains whether to purchase or produce sodium hypochlorite. Two reasons our customers chose Microclor® OSHG come down to safety and fewer deliveries.

Safety

Microclor’s® OSHG dilute (0.8%) hypochlorite solution is below most hazardous material concentration thresholds of 1%. This reduces operator HazMat exposure and eliminates the need for diluting commercial hypochlorite to compensate for degradation which results in inconsistent solution strength.

Fewer Deliveries

The only raw materials required for the OSHG process are salt and water. This will reduce vendor deliveries by about 66% compared to commercial bulk hypochlorite. Less truck traffic through the community and at the facility will reduce the potential for accidents and eliminate the associated carbon footprint, furthering efforts towards Green Facility Management and improves the water security profile of your facility.

Save More with Microclor®

Reduced Operational Expenses

Since all chlorine compounds are derived from salt, on-site electrolytic conversion can result in significant savings to the owner. Typically, it costs less to produce sodium hypochlorite as compared to buying it as commercial grade hypochlorite.

Continuity of Operations

Microclor® OSHG will enable storage of larger quantities of raw materials (salt) necessary for your disinfection process. This will result in a more sustainable and robust treatment facility better able to withstand price fluctuations and the demands imposed by natural disasters or health emergencies.

Superior Results by Design

The patented Microclor® OSHG design is the result of over twenty-five years of experience in the manufacturing, installation and servicing of hypochlorite generation equipment.

Vertical, Multi-Cell Configuration

The breakthrough multiple, vertical cell design of Microclor® OSHG allows it to immediately vent by‐product hydrogen away. It also improves resilience by allowing for continued hypochlorite production even with individual cell removal.

Compact Cell Design

The cell’s vertical orientation not only allows better hydrogen separation but is also more compact, resulting in a more space-efficient footprint. The clear acrylic cell body supports the electrode array and eliminates the need for internal baffles and fasteners, reducing maintenance and repair costs over the life of the system.

Advancements in system safety and ease of operation make Microclor® OSHG the overwhelming choice for water treatment professionals.

Microclor OSHG. Simple. Efficient. Reliable.

Direct Hydrogen Management

The electrolytic cells are configured in a vertical array and vented directly to atmosphere. This prevents the chance of over pressurization by releasing virtually all hydrogen directly from each cell. Other systems use the storage tanks as hydrogen separators which can contribute to excessive cell pressure and vibration in the discharge piping.

Continuous Process Control

Microclor’s® OSHG integral brine pump is controlled by the PLC to optimize salt conversion efficiency and hypochlorite production. Automating precise brine control reduces operator intervention and improves system effectiveness.

Full-Wave DC Power

Automated brine control allows full-wave rectification which greatly reduces excess heat and the number of components necessary in the rectifier. This reduces facility HVAC loads and improves system reliability.

High-Velocity Electrolyte Circulation

The hydraulic lift created by the hydrogen separation circulates electrolyte through the cell loop at 3 fps. This reduces the requirement for cell cleaning and minimizes heat accumulation in the cell.

System Overview

The Microclor® OSHG system is modular in design and utilizes standard components that are easily customized to meet a wide range of requirements.
