The IWWT®-Linearbegaser

The IWWT®-Linearbegaser is the new highest efficient system for pressing gases into water

IWWT®-Linearbegaser: lower costs and more climate protection by fewer energy use


The efficiency of the entry of gases into water is determined by the two parameters of the smallest possible gas bubble diameter and undisturbed diffusion space of each individual gas bubble during their residence time in the water. The IWWT®-Linearbegaser meets these requirements like no other gas entry system in water.

Why does a gas bubble form in the water? A gas bubble forms in the water, because more gas is added than can go into solution in the water.                          

The ratio of bubble number and bubble surface

Usually air, oxygen O2 or ozone O3 is introduced into water. For the wide range of applications of the IWWT®-Linearbegaser.

What do gas bubbles in the water mean for costs and climate protection?

For the costs bubbles in the water mean that the amount of energy used to press in the gas bubbles is lost, and that means the money for generation of energy to introduce gas bubbles into water is lost too.

For climate protection gas bubbles in water mean the generation of energy above the demand and – as long as coal-fired power plants are operated – the climate is unnecessarily burdened by more CO2 or the energy is not available for climate-friendly use.

Efficiency of gas input into water

The distribution of a gas flow in water determines the efficiency of the gas input.

The efficiency of the gas input is defined by the proportion of gas pressed in which remains in the liquid.

The efficiency of the gas input depends on 2 parameters

1st parameter – Diameter of the gas bubbles pressed in

A registered volume flow of the gas must be suspended on the way from the compressor to the entry points into the liquid up to the surface of the water in a maximum of individual gas bubbles.

The more gas bubbles of the intake volume flow is decomposed, the larger is the contact surface between all gas bubbles and the liquid.

The contact surface is equal to the diffusion surface.

The entire diffusion surface is the contact surface over which the gas of all bubbles passes into the liquid.

2nd Parameter – Arrangement of the gas entry points into the water

Each gas bubble needs enough diffusion space from the outlet from a IWWT®-Linearbegaser or from a conventional aerator or from an injector to the water surface for the gas to pass from the gas bubble into the water.

For optimal efficiency of the diffusion of the gas into the water, the diffusion space of each individual gas bubble must not be disturbed.

The diffusion spaces of two or more gas bubbles are disturbed by the superposition of too close together entry points of the respective gas bubbles.

IWWT®-Linearbegaser for the today´s most efficient gas input into water

With IWWT®-Linearbegaser, air or oxygen O2 or ozone O3 is the today´s most efficiently and environmentally friendly introduction og gas into water.

With openings in the pipe wall with a diameter of 30 microns to 70 microns, the gas stream is broken into gas bubbles with diameters up from 1.5 mm.

The distances of the entry points are arranged so that each gas bubble has its own diffusion space and that the gas is optimally distributed in the water.
