Water Purification: Managing Duplicant Pollution Output

In the game Oxygen Not Included, duplicants produce polluted water when they are stressed, as well as through amenities such as lavatories, showers, wash basins, and sinks. A lavatory produces 11.7 kg of polluted water and consumes 5 kg of clean water, making it water positive. With the default schedule, each duplicant will use the lavatory once every cycle, creating 6.7 kg of polluted water per cycle. Thus, with 8 duplicants, the total amount of polluted water produced per cycle would be 53.6 kg. This can be managed through various strategies such as using excess water for an electrolyzer, creating a closed-loop system, or converting polluted water into clean water through filtration.

A lavatory produces 6.7kg of polluted water per cycle per duplicant

It is important to note that this is an oversimplification and that there are other variables that can impact how many times a lavatory can be used in a cycle. For example, the time it takes for a duplicant to do their business may vary if they are ill or have the Irritable Bowel trait. Additionally, the number of lavatories available may affect how often duplicants go on the floor, but it would not otherwise impact the end number.

The polluted water produced by lavatories can be a problem, as it can fill up the washroom loop and require an overflow. One solution is to use a tank to accumulate the polluted water and use it to feed an electrolyzer or a petroleum generator. Another option is to use a water sieve to purify the polluted water, turning it into pure water that can be deposited from a liquid vent. However, it is important to note that filtering polluted water does not remove any germs that may be present, so additional steps may be necessary to ensure the clean water is not contaminated.

Overall, understanding the amount of polluted water produced by duplicants and the options for managing it is crucial for maintaining a functional and healthy environment in the game.

Duplicants produce polluted water when they are stressed

In the game Oxygen Not Included, duplicants produce polluted water when they are stressed. This can occur through stress-induced vomiting or when a duplicant doesn't reach a toilet in time. A lavatory produces around six times more polluted water than a duplicant not reaching a toilet in time. With a default schedule, each duplicant will use the lavatory once every cycle, producing 6.7 kg of polluted water. This can be recycled or used in a fertiliser synthesizer to produce fertiliser.

There are other ways to manage duplicant stress and prevent the production of polluted water. For example, ensuring the base has plenty of decor and storage, and minimising clutter on the floor. Players can also increase the number of paintings, particularly those made of granite which has a decor bonus.

Polluted water can also be produced as a by-product of certain amenities, such as lavatories, showers, wash basins, and sinks. It can also be created through the use of algae distillers and carbon skimmers. Polluted water has a higher specific heat capacity than water and a larger boiling and freezing range, making it a great coolant. While it can be pumped and purified via a liquid pump and water sieve, this process does not remove any germs that may be present.

It is important to note that polluted water can have negative effects on duplicants if they walk or become submerged in it, adding to their stress. This can create a cycle of stress and polluted water production. Therefore, it is essential to manage stress levels and prevent the accumulation of polluted water.

Petroleum generators produce 450kg of polluted water per cycle

Petroleum generators are a great source of energy, converting petroleum or ethanol into electrical power. However, they also produce a significant amount of waste, including carbon dioxide and polluted water. This waste can have negative consequences if not properly managed.

The amount of polluted water generated by petroleum generators is substantial, with each generator producing 450kg of polluted water per cycle. This is a significant amount and can be utilised in various ways. For example, the polluted water can be used to feed approximately 6.42 domesticated Arbor Trees, as they require around 504kg/cycle. Additionally, the polluted water can be used to regrow Arbor Trees, and the resulting polluted dirt has multiple applications, such as generating oxygen or producing coal through Sage Hatches.

Another application of the polluted water produced by petroleum generators is in the fertiliser synthesis process. By combining 39g/s of polluted water with 65g/s of dirt and 26g/s of phosphorite, fertiliser and natural gas can be produced. This efficient use of resources can be beneficial for sustainable practices.

It is important to note that the polluted water generated by petroleum generators is germ-free, which can be advantageous in certain contexts. This purity can be beneficial for specific applications, such as irrigation or industrial processes that require clean inputs.

While the polluted water produced by petroleum generators can be useful, it is essential to consider the overall impact on the environment and the potential consequences of improper waste management. The high energy output of petroleum generators must be balanced with the significant waste they produce to ensure sustainable practices and minimise negative environmental effects.

Polluted water can be purified using a water sieve

Polluted water is created when a duplicant doesn't reach a toilet in time, or through stress-induced vomiting. Lavatories, showers, wash basins, and sinks also convert water into polluted water. A lavatory produces around six times more polluted water than a duplicant not reaching a toilet in time. A lavatory will take 5kg of water and each time it is used, it puts out 11.7kg of polluted water. This means that with the default schedule, each duplicant will use the lavatory once every cycle, creating 6.7kg of polluted water each cycle.

The water sieve is a very helpful building as polluted water is a very important resource. It allows a colony to operate structures like the carbon skimmer or the lavatory without consuming polluted water by instead consuming clean water. However, it is important to note that the water sieve does not remove any germs that may be present in the polluted water. The germs will remain in the clean water unless additional steps are taken.

There are ways to decontaminate the germ-infested water. One way is to use a liquid bridge pipe design and a bit of automation. This design will send a signal when all three tanks are full, ensuring that all germs are gone by the time the germy polluted water passes through all three tanks to the water sieve. Another way is to use chlorine to kill the germs.

Polluted water can be used to produce fertiliser

Polluted water is created when a duplicant does not reach a toilet in time or through stress-induced vomiting. It can also be produced as a by-product of certain amenities such as lavatories, showers, wash basins and sinks, which convert water into polluted water. A lavatory produces 11.7 kg of polluted water and consumes 5 kg of clean water, resulting in a net increase of 6.7 kg of polluted water per use. With eight duplicants, this can quickly add up to a substantial amount of polluted water.

While polluted water can have negative effects on duplicants, it is a valuable resource that can be utilised in various ways. One important use is in the production of fertiliser. Polluted water can be used in a Fertilizer Synthesizer to create fertiliser, which is an essential resource for agriculture. The process involves combining 39 g/s of polluted water, 65 g/s of dirt, and 26 g/s of phosphorite, resulting in 120 g/s of fertiliser and 10 g/s of natural gas. This not only helps in disposing of polluted water but also ensures a steady supply of fertiliser for your crops.

Additionally, polluted water is a superior coolant compared to pure water due to its wider temperature range. This property can be particularly useful in early-game cooling applications. Polluted water can also be used to grow specific plants that thrive in it, such as the Pincha Pepper, Thimble Reed, Bog Bucket, and Arbor Tree. These plants can be utilised for food production or other purposes.

It is worth noting that polluted water can be purified and converted back into clean water. This can be achieved through various methods, including using a water sieve, boiling it into steam, or employing a Gulp Fish to clean it. However, simply mopping up small amounts of polluted water (less than 150 kg) is also an option, especially if it is submerged at the bottom of a tank.
