The waste coming from any kinds of activities will be stored in the effluent, aeration functioning as the filter for solid dirt and rubbish that an obstacle for further equipment process or other water types of equipment that had been filtered to further go into equalizing function as saving water in initial process in order for average and regular water quality
After that the water is pumped into flow control box for further go into the aeration tank, this aeration is supplied with diffuser water that functions to dilute air into the water so that the bacteria to be active.
In the aeration, wastewater will be processed by adding or diluted air into water and add activated sludge that is obtained from sedimentation tank.
This tank functions to bend down sludge that comes from aeration having the objective to speed up the structure of bending down, so it is made in quadrangle size. The bending down sludge will be removed by airlift through air blower, and then the sludge is stored in every distributor box to be distributed to the aeration tank, effluent tank and chlorine tank. After the water bending down, next it adds chemical substances functioning to kill germs but CV. SURYA TIRTA BUANA does not use chemical substances, this matter can be solved by adding more active bacteria during the aeration process. The water tank of water processes or effluent tank is the tank functions as the tank for storing processed water produced by the unit of wastewater processed to be distributed to a water tank, water that goes into this tank is the water after being processed which is free from germs.
Before entering makeup water tank, processing water waste will be filtered using sand and carbon to erase color and smell taste, next will be stored into aeration tank and in the tank is recycling water that has been prepared safely for the usage of water needs such as cooling tower, boiler laundry, toilet flusher, watering plants, general cleaning, fish pond, car wash and other water needs.TECHNOLOGY
To prevent environmental pollution from waste, now it has been mostly used a system of maintaining of modern domestic wastewater namely Sewage Treatment Plant ( STP ). The STP system consists of any kinds which one of them is using the system of Activated Sludge or it is called Extended Aeration. This system is mostly used at the moment.
