Castor HR Consulting Ltd
Specialist in the operation and improvement of industrial water treatment systems. From my background in continuous industrial production, process troubleshooting and management in the paper and other industries I am developing a business where a strong technical base is used to evaluate and improve water systems. Non-specialist managers of plants often struggle to evaluate alternative approaches to changes in procedures, equipment or chemicals. From experience on all sides of these operations I am able to independently help to predict short-comings; design and monitor valid trials. I act as an arbitrator to manage expectations with practicalities. Agent for Rithco Airjec - Updated aeration for Dissolved Air Flotation to save most of the energy load. Specialities: Fresh water treatment, effluent water treatment, water plant optimisation, paper process optimisation, odour control, water plant financial optimisation, microbiological control in water systems, foam control, boiler water

Dissolved air systems used in DAF clarifiers are governed by the physics of air solubility in water. High flows of water at high pressure are needed, requiring significant energy for the water pump and also the air compressor. Even under ideal conditions 1 cubic metre of clean water will only dissolve 100 litres of air (at 5 bar and at 30° C).
Additionally, the air solubility is dependent on a number of factors including temperature and water quality; meaning that poor quality clarified water can cause further flotation issues.
The Airjec Diffuser is a unique device for the formation of air micro-bubbles to replace conventional pressurized vessel aeration systems on flotation water clarifiers.
A relatively small flow of water is used to kinetically draw in air by suction from the surrounding atmosphere. The configuration of the mixing chamber is designed to form a bubble size distribution ideally suited to particle flotation.
Typically 1 cubic metre of clean water will carry 4 000 litres of air.
The kinetic energy of the water is independent of water quality; so, within some constraints, the aeration is not effected by suspended solids. This means that aeration is not reliant on good water quality removing the escalation of poor operation.
The system is designed to generate bubbles that are ideally suited to solids separation in clarifiers.
Using the different physics will save >80% of the aeration energy, removing the need for a compressor and greatly increasing the stability of operation.
