Abstract: A method, system and apparatus for treating water is provided including a treatment mode comprising the steps of drawing said water from a pressurized water source through a controlling device to a treating vessel, the water inlet of said treating vessel being substantially at the top of a treating vessel, contacting said water with pressurized air present at the top of said treating vessel to release substantially all hydrogen sulfide and offensive odors present in the water and to dissolve oxygen in the water which reacts with soluble iron in the water to form ferric oxides, flowing the water through a filter bed of calcite mineral to remove substantially all sediment present in the water and to neutralize the ph of the water and to remove substantially all the ferric oxides from the water, the ferric oxides fastening to the calcite minerals and to already fastened ferric oxides, flowing the water to a final media means and to the outlet of the treating vessel.

Abstract: A multi-skill question and answer board game which can be competitively and simultaneously played by players of different skill and age levels comprising a game board with a one directional playing track along which each player moves their pieces based upon the value of the roll of a single die, the track is made up of plurality of different topic sectors, a number of sets of multi-skill level topic cards bearing questions for each topic to which each player must reply once he has chosen the skill level, the higher the skill level chosen the higher value given to the correct answer.

Abstract: A method for determining carbon content in fly ash includes providing a source of fly ash and a microwave interrogation chamber. A quantity of fly ash is introduced into the interrogation chamber and exposed to microwave energy. The amount of carbon in the fly ash is determined by measuring the amount of microwave energy exposed to the fly ash, the amount of energy transmitted through the fly ash, and the amount reflected therefrom in order to determine the amount of energy absorbed. The concentration of fly ash is preferably determined by determining the weight of the fly ash and determining the percentage of carbon content in the fly ash. The method is particularly useful in respect of monitoring carbon content in fly ash of boiler exhaust gases. The system may also be employed to determine the fly ash glass content of fly ash. An associated apparatus is also disclosed.
