EMPLOYMENT OF THE OLOID TECHNOLOGY FOR THE TREATMENT OF:
LEACHATE OF COMPOST & WASTE DISPOSAL SITES
The leachate of compost and waste disposal sites must not reach the ground-water because of its pollution with COD, BOD5, ammonium, and other nutrients. That’s why it is collected in cisterns, tanks, or ponds and re-used for irrigation on compost sites. However, leachate tends to be rather odoriferous due to its high pollution load. This makes irrigating compost pits with leachate difficult or impossible. In many countries, leachate may only be disposed of by public sewage treatment plants and against high charges.
The OLOID is able to aerate and gently circulate the leachate so a substantial part of these unwelcome nutrients is degraded and the water looses its penetrating smell. The leachate may now be used for irrigation. Thanks to the degradation of the pollutants in the water, you may cut down on sewage treatment charges. The OLOID is, moreover, highly economical as to energy consumption: the net power consumption of an OLOID-Type 400 A is approximately 250 W. In fact, an OLOID plant will be amortized in a mere few months.
TESTIMONIAL: COMPOSTING ERNST LANDES, GER
"Since September 2000 an OLOID-aerator type 400A is in operation in our 300 m3 compost leachate tank. The aerator allows a steady oxygen transfer into the water on a constant high level and a good distribution of the oxygen in the tank. This leads to an active biology in the tank. The energy consumption decreased significantly. Before the OLOID-aerator was installed, two injector-aerators were in operation in the tank with a power consumption of 7,5 kW each. These aerators operated each 4 hours for 20 minutes... These were not able to provide a constant level of oxygen. ...With the OLOID-aerator we have good conditions for an active biology in the tank and we can save a lot of energy."
Power demand per day decreased. Biological degradation of the water pollutants is better and the fees that have to be paid to the sewage treatment plant have decreased.
