4.2 Implementation of Water Recycling Program

4.2-1 Recycling Waste Water from ponds, natural ponds for lawns and trees.

— To install water pumps by using sprinklers within the wastewater treatment ponds for watering the lawn.

— To use water from natural ponds, for watering trees to replace tap water (Figure 4.2-1)

                                                                            1.Water is flowed through the sand, carbon,                          2.Then run into Reverse Osmosis

                                                                                                 and resin strainers.

                               

3. It cannot produce drinking water flows into the tube and then separates from the tank.

                           

                 4. The water flows in the pipe to the first floor of the building.     5. Then, flow in the pipe which is connected to the tank on the first floor.

                                                 

6. The water is kept in the pump for daily use.

                                    

        7 .The recycled water is used for cleaning up the floor.             8. Using recycled water in flushing the toilets.

4.2-4 Water Recycling System in Tilapia Hatchery

Water Recycling System in Tilapia Hatchery. The water is used to hatch the fish that is supplied with flowing water all the time. The water from the hatching tubes will flow into the support tray before flowing into the PVC pipe and circulating through the hose to return to the top of the hatching tubes. With this system of rotation can reduce the amount of water needed each day. The amount of water need to be added each day is about 2% of the total system water is about 20 liters.
