In Singapore, wastewater treatment is one of the common ways of controlling pollution. Manufacturers are even required in complying with the laws that are made to eliminate this problem. Thus, if you operate businesses in industrial zones, then you should know how this service works!
Here are the processes that you will get from wastewater cleaning services!
Collection
In order to ensure that all wastewater is in one place before treatment, service providers make use of underground drainage systems to collect it. This transportation of wastewater should be done in hygienic conditions that is why all the pipes are leak-proof and the personnel are wearing protective clothing.
Odour control
Wastewater contains dirty substances that can cause a foul smell to spread. The treatment plants are regularly cleaned using high-pressure water cleaner so that odour sources can be eliminated. They would use chemicals that can neutralise the elements that produce foul smells.
Screening
This step is crucial in the process of wastewater cleaning because this is where large objects in the water are removed. For example, there are plastics, rags, bottles, diapers, among many other things that could damage the equipment that will clean the water.
Treatments
After the screening process, the wastewater will undergo at least three treatment processes that are done to filter all the bacteria from the water. They will use microorganisms that can consume organic matter and heat it. You could get a tertiary treatment that can remove 99 per cent of the impurities in the wastewater!
Disinfection
This is an integral part of the treatment process because it ensures the health of the animals and locals who will use the water for other purposes. To achieve this, the wastewater is contained and disinfected for at least 20 to 25 minutes in tanks that contain a mixture of cleaning chemicals!
