Overview of waste water

Liquid waste sourced from manufacturers who usually use a lot of water in the system process. Industrial wastewater for agriculture is very much water is used for:
  1. cleaning materials and food processing equipment.
  2. away materials that do not want (dirt).
The liquid waste originating from agriculture industry contains many organic materials (carbohydrates, fat and protein) because it is easy to rot with a problem of air pollution (odor) and water pollution. In addition there is also a raw material containing water so that the processing process water must be discarded. Water from ending up in the processing and then discarded for example when used for washing a material before further processing. Water plus certain chemicals and in-process and after it is removed, all types has resulted in waste water treatment. In some factories, such as a wire processing factory, zinc, iron steel - most of the water used for cooling the casting machine, or kitchen. Water is pumped from its source and then passed on the parts that require cooling, and then discarded.

Therefore, the channel of water flowing in the plant looks a fairly large volume. Boiler water will be disposed of at certain times after the laboratory examination, because water is no longer qualify as a water kettle and should therefore be discarded. Along with the need for good amounts of water to wash the inside of the washing water kettle should also be discarded. Washing factory floor every day for several specific plant needs water in large quantities. Fish canning factories require washing water in quantities should be a lot, amount of water required continuous washing equipment, floors, etc., rust need to be washed before entering and upon chopped pencincangan constantly flowing water to remove sand-borne ash.

Water from the plant brought a number of both solids and particles that dissolve or precipitate. This material is rough and smooth. Often colored turbid water from the factory and high temperature. Water containing toxic and hazardous chemical compounds have the nature of its own. Waste water that is polluted giving 577 features that can be identified visually can be known from turbidity, water color, taste, odor generated and other indications.

While identification in the laboratory, marked by changes in chemical properties of water where water already contains toxic chemicals and hazardous in concentrations that exceed recommended limits. Types of industrial liquid waste include the industries of pulp and rayon, the processing of crumb rubber, palm oil, steel and iron, cooking oil, paper, textiles, kaustiksoda, electro plating, plywood, tapioca flour, canning, dyeing and coloring, meat and others. The amount of waste removed each of these industries depends on a lot of production being generated, and the type of production. Pulp and rayon industries produce waste water as much as 30 m3 per tonne of pulp produced. For fish and seafood industry waste water ranges from 79 m3 to 500 m3 per day; crumb rubber processing industry waste water ranging from 100 m3 to 2000 m3 per day, palm oil processing industry has a waste water: average of 120 m3 per medium-scale day.
