Garbage Disposal for Gray Water Treatment Plant

garbage disposalWastewater from households or office building can contaminate the environment if it is disposed of carelessly. It is should be further treated in a proper garbage disposal system. Generally, wastewater is divided into 3 types; they are gray water, black water, and clear water waste. Each of this waste water needs different management before being disposed of because each of them has its own characteristics.

Proper Garbage Disposal for Gray Water

Gray water is all waste water without fecal contamination which is generated in households or office buildings, including waste water from sinks, showers, baths, washing machines, and dish washers. This waste water needs a different management from the one that contains fecal contamination or black water so it can flow together to the same garbage disposal management. Gray water commonly contains antiseptic which possibly kills the microorganism needed in black water management. Gray water contains fewer pathogens and is generally safer to handle although it needs an advanced management. Traditionally, to reduce the amount of contaminant contained in gray water, some plants like a water lily, sword plant, or cat tail can be planted in the banks or bodies of ditches. However, this method is claimed as an ineffective way since the plants cannot neutralize too much contaminant.

A more advanced garbage disposal system is needed in gray water treatment. The most simple water treatment system for managing gray water waste needs two tanks which are collector tank and absorption tank. In the collector tank, gray water waste will be filtered. Small trash and oil which possibly still left in the waste water will be separated from the water itself in this collector tank. After the gray water is free from oil and other trash, it will flow to the absorption tank in which the water is once again filtered from the contaminant substances through biochemical process.
