Water pollution can be characterized from various perspectives. Usually, it means one or more substances have built up in water to such an extent that they cause problems for animals, people and our environment. There are many factor that can lead to the water pollution such as waste water that produced from the factory that flow to the river or sea, waste water that drain out from the car wash centres and others .On top of that, we need the water treatment to get the good quality of water resources and prevent the activities than can lead to the water pollution.
From the case of study, nowadays, we know that many car washes centre that operating in the country. Due to there are too many car wash centre in our country, the water pollution may occur from this activities. In view of the scientific investigation of the previous years, washing the vehicle in the public area may cause the water pollution because from the waste water containing dirt, chemicals, black grease, tar and oil brakes that stick out from the cars. The impact of these activities is clearly violating the Environmental Quality Act 1974.
Car wash centres make wash wastewater that can have a great impact to the environment if not appropriately managed and discharged to the right places , the contaminants are include the oil and grease which contains the hazardous material , detergents are made from the chemical that can cause the pollution of water quality and can poisonous to fish which is our food resources , the trash that contain from the car wash wastewater can clog the drainage from flow to the sewer and produced bad fumes.
On top of that, by using snow wash in the car wash operating centre can cause many side effects to the environment and living things. From the snow wash detergents there are a lot of chemical. The chemical that are contains in the snow wash detergent can lead to the water pollution of especially, if the entrepreneur of the car wash centre does not take a good care of the runoff the wastewater directly to the drainage. Review discovered that the washing facility not provided with a waste water flow system, including allowing it to stream into the streets. That is the major causes of the water pollution from the car wash wastewater.
The improvement of a prevention to reduce the impact of runoff car wash wastewater to the environment and also reduce the discharged of wastewater to the drainage system by using a commercial car wash. Commercial wash must be conducted by professional car washes, so that they are preserving about the wastewater from their washing water. Besides, they can make the full system of drainage that can prevent the wastewater directly flow to the drainage with the residual.
In the other way to prevent the car wash wastewater pollution is washing the cars on the grass or permeable surface. By doing this, it definitely can treat the wastewater naturally. It is because the wastewater directly flows to the permeable surface so that the soil and the rock inside the permeable surface can act as the filter. This can reduce the wastewater flow with the contaminant directly to the river or sea. It naturally can conserve our water resources from the pollution.
To reduce the water pollution from the car wash wastewater, the entrepreneur of the car wash centres must conduct the drainage systems that environmentally friendly to the user and also to the environment. This system can be minimizing the pollution from the car wastewater. The way to conduct the system that environmentally friendly is by using biodegradable cleanser and chemicals rather than dissolvable based arrangements. Secondly reduce the amount of the detergent and make the water filtration. So that, it can lower the amount of the residual of the suspended solids or chemical that discharge to the drainage.
We can conclude that water is one of the important sources on the earth to the environment and all living things. We as a human must take a good care of the water to prevent it from pollution. As we are discussed about the car wash wastewater pollution, there are such major things that can be lead to the water pollution nowadays. Starting from now, we must act wisely to maintain and conserve our environment in every aspect. At the same time we can save the water resources if we conserving about the wastewater treatment.
