Water is a habitat for many organism, oxygen is necessary for them to survive. he oxygen for respiration. They need a minimum of 4 mg O2 per liter of H2O to survive without damage.  The amount of dissolved oxygen is therefore a balance between absorber and donator, temperature and other substances dissolved. If this balance is seriously disturbed, one would speak of waste water
           The model RX-2 consists of two wheels where in between are six baskets mounted. The baskets are open on top and have a lot of small holes at the walls and at the bottom. This ensures, that, when the wheels turn, the baskets are filled quickly when diving into the water and empty slowly in a lot of thin water jets, maximizing its efficiency by creating turbulence in the water.

Suitable for use in public and natural water sources such as ponds, swamps, canals, lakes, creeks, etc. In case of polluted, the aerator is used in combination with water hyacinth.

Presentation editorial

Presentation structure Effective Presentation Techniques 1. Use visual aids Using pictures in your presentations instead of words can double the chances of meeting your objectives. 2. Keep it short and sweet 3. Use the rule of three A simple technique is that people tend to only remember three things. Work out what the three messages that you want your audience to take away and structure your presentation around them. Use a maximum of three points on a slide. 4. Rehearse Practice makes for perfect performance. Many experts say that rehearsal is the biggest single thing that you can do to improve your performance. Perform your presentation out loud at least four times. One of these should be in front of a real scary audience. Family, friends or colleagues. Even the dog is better than nothing. 5. Tell stories 6. Lose the bullet points – don’t put your speaker notes up on the screen Bullet points are the kiss of death for most presentations.
