Using Polluted Water In Oni: A Guide

Polluted water, formerly known as contaminated water, is a common issue in the game Oxygen Not Included. It is water that contains waste and can be infected with germs. While it can be a nuisance, polluted water can be put to good use in several ways. One option is to use it for cooling, as it has a high specific heat capacity and a wide boiling and freezing range. It can also be used to feed plants or converted into steam to power your base. Additionally, it can be purified and reused or stored for later use. This guide will explore the various ways to utilise polluted water in the game, ensuring that players can make the most of this resource.

Purify polluted water into clean water using a water sieve or gulp fishes

Purifying polluted water into clean water can be done using a water sieve or gulp fishes. Here is a detailed description of both methods:

Using a Water Sieve

A water sieve is a building that helps convert polluted water into clean water. It uses a filtration medium, such as sand or regolith, to purify the water. The process is quite simple: polluted water is pumped into the water sieve through a liquid pump, and the filtration medium removes the impurities, resulting in clean water. For every 5 kg of polluted water and 1 kg of sand or regolith, you get 5 kg of clean water and 200 g of polluted dirt as a byproduct. It's important to note that the water sieve doesn't remove germs, so separate sieves should be used for filtering clean and waste water to prevent germ proliferation. Additionally, the water sieve doesn't change the temperature of the water.

Using Gulp Fishes

Another method to purify polluted water is by using gulp fishes. This method is quite fascinating as it involves using fish to clean the water. Gulp fishes can take in polluted water with temperatures ranging from 20-40°C and output clean water at 2°C. One of the advantages of this method is that it doesn't require feeding the fish or any duper labor. However, it does need refined metal, ethanol, and access to shipping techs. Additionally, it is important to continuously replace the fish or their eggs, as some may be born as tropical pacu, which freeze to death at low water temperatures.

It is important to note that polluted water is a common occurrence in the game, especially in the Swamp Biome and Frozen Biomes. It can be created when a duplicant doesn't reach a toilet in time or through stress-vomiting. While it has its uses, such as a coolant and for growing certain crops, it can also have negative effects on duplicants, adding stress if they walk or submerge in it. Therefore, purifying polluted water is an essential aspect of the game to maintain the well-being of your duplicants and ensure a steady supply of clean water.

Use it to cool down systems as it has a high specific heat capacity

Water is vital for all life on Earth, and its unique properties make it an excellent coolant. Water has a high specific heat capacity, meaning it absorbs a lot of heat before it begins to get hot. This is defined by the amount of heat needed to raise the temperature of 1 gram of a substance by 1 degree Celsius (°C). Water's high specific heat means it takes more energy to increase its temperature compared to other substances. This property is why water is used as a coolant in industries and car radiators.

Similarly, polluted water also has a high specific heat capacity, making it a great coolant. It has a reasonable thermal conductivity, and its boiling and freezing points are also suitable for cooling systems. For example, polluted water has a boiling point of around 120°C and a freezing point of approximately -20°C. These properties make it a valuable resource in the early game, as it can be obtained easily and used to cool down systems efficiently.

The specific heat capacity of polluted water can be advantageous in various applications. One example is in cooling loops, where it can be circulated to absorb and dissipate heat. This is particularly useful in systems that generate a lot of heat, such as electronics or industrial processes. By using polluted water as a coolant, the system can maintain a stable temperature and prevent overheating. Additionally, polluted water can be used in cooling systems for buildings or other structures, helping to regulate indoor temperatures and create a comfortable environment.

Moreover, the high specific heat capacity of polluted water can be beneficial in energy generation and storage systems. For instance, in power plants or renewable energy systems, such as solar thermal or geothermal energy, polluted water can be used as a heat transfer fluid. It can absorb and store thermal energy, providing a way to manage and utilise heat more efficiently. This application can improve energy efficiency and reduce the environmental impact of energy generation.

Overall, the high specific heat capacity of polluted water makes it a valuable resource for cooling systems. Its ability to absorb and store heat efficiently makes it a versatile coolant, suitable for a range of applications. By utilising polluted water in this way, we can take advantage of its unique properties to manage heat more effectively in various systems and processes.

Feed it to specific plants like Pincha Pepper, Thimble Reed, and Bog Bucket

Polluted water can be used to feed specific plants like Pincha Pepper, Thimble Reed, and Bog Bucket. This method is especially useful if you have an excess of polluted water.

Pincha Pepper, Thimble Reed, and Bog Bucket can be grown using polluted water. Thimble Reed, in particular, is a safe choice as it consumes a large amount of polluted water and never gets germs. According to one source, Pincha Pepper requires 35 kg/cycle of polluted water, Thimble Reed requires 160 kg/cycle, and Bog Bucket requires 40 kg/cycle.

It is important to note that while plants can consume germs from the polluted water, there is a risk of food poisoning if the food is not cooked. Cooking the food will eliminate the risk.

Additionally, polluted water can be used as a coolant due to its high specific heat capacity and wide boiling and freezing range. It can also be purified and converted into pure water using a water sieve and a filtration medium.

Store it in a reservoir where it won't off-gas or use a deodorizer

Polluted water is a common occurrence in the game, especially in the Swamp Biome, and can be used for many purposes. One of the ways to store polluted water is in a reservoir, where it won't off-gas. This is because the liquid reservoirs do not emit any polluted oxygen, which is useful for players who want to store the polluted water for later use.

Another way to store polluted water is by using deodorizers. Deodorizers can be placed in choke points where the polluted oxygen has to pass through to access your base. This will ensure that the polluted oxygen is converted to oxygen, and you won't have to worry about your duplicants breathing it in. Deodorizers can also be placed above the storage tanks to ensure that you get nice oxygen.

Additionally, you can use a layer of CO2 to prevent off-gassing. A thin layer of normal water can also be used to achieve the same effect. This is because the polluted oxygen lets slimelung proliferate, and a single puff of contaminated PO2 can turn your atmosphere into poison gas.

One user on Reddit mentions that they store their polluted water in reservoirs in a chlorine room and then reuse it. They also mention that polluted water is always useful, as it is a great coolant and can be used in various cooling systems.

Turn it into steam and use it in steam turbines or steam engines for power

Polluted water is a common issue in the game Oxygen Not Included, and there are several ways to deal with it. One method is to turn it into steam and use it to generate power through steam turbines or steam engines. Here is a detailed guide on how to do this:

First, it is important to note that polluted water has a high specific heat capacity and a wide boiling and freezing range, making it a great coolant. This means that it can be used in cooling loops to regulate temperatures in your base. By creating a closed-loop system, you can reuse the same polluted water repeatedly, ensuring an efficient and sustainable cooling mechanism.

To turn the polluted water into steam, you can utilise a liquid tepidizer built out of gold ore. Gold ore is an excellent material for this purpose as it can withstand high temperatures without melting or sustaining damage. Ensure that the tepidizer is placed in a basin insulated with granite tiles to prevent heat loss. The water will evaporate, leaving behind sand and fertilizer, which must be removed to prevent the tepidizer from malfunctioning.

The resulting steam can then be directed through airflow tiles into an adjacent basin or chamber. Here, the steam will recondense into fresh water, which can be collected and stored. This process effectively distills the polluted water, making it safe for consumption or other purposes.

Finally, you can utilise the generated steam to power steam turbines or steam engines. Steam turbines, in particular, can be placed at the bottom of your base, where the hot steam will rise and turn the blades, generating electricity. This method of power generation can be sustainable and efficient, especially if coupled with your cooling loops. Remember to insulate and store the steam effectively to maximise its potential.

By following these steps, you can not only manage your polluted water but also generate a valuable source of renewable energy for your base in Oxygen Not Included.
