1. Farm inlet
Bring water to dissolved-oxygen saturation before distributing it to the ponds. Ozone transfer for inlet disinfection can also be considered with a compatible configuration and a separately designed treatment process.
Dissolved oxygen and compressed air, powered by water
Koohub HMTR is designed for farms with flowing water and at least one metre of available head. Using the energy of water flow, it delivers water saturated with dissolved oxygen regardless of the inlet dissolved-oxygen level, while supplying compressed air at a typical pressure of 0.7 bar. Process gases such as ozone can also be dissolved using a suitable configuration and compatible materials.
HMTR requires no electricity or fuel to operate. Its composite body and design without moving parts provide a design life of at least 25 years, with no internal maintenance required under standard operating conditions.
To estimate dissolved-oxygen equilibrium for your water temperature and site altitude, use the calculator on the HMTR page.
The hydraulic head H supplies the energy that drives the device
Four suggested installation locations
The location and number of devices are selected to suit the water route and the farm’s needs. Each system can discharge directly into tanks or into a distribution channel.
Inlet water flow per device: 20–1,000 litres per second
Device dimensions are selected to suit the water flow and site conditions.
Use the device’s air supply with companion equipment
Airlift pump
Air-powered water transfer at low head; dimensions and installation depth are selected to suit the transfer route.
Airlift mixer
Air-driven circulation and mixing, configured for the pond’s geometry and depth.
Pneumatic pond vacuum
Collect sediment from the pond floor. Air enters through the hollow handle, while water and sediment leave through a separate hose.
