Ozonation Purification Unit

The Ozonation Purification Unit (OPU) is an LuV tier multiblock used for the second step of the Waterline. Its automation challenge is very simple: it requires large amounts of Ozone to run, which needs to be produced fast enough to keep up with its 120 second cycle.

The OPU has no tiered components or energy hatches because it receives power directly from the Water Purification Plant once linked with a data stick, like the rest of the Water Line multiblocks. Use the Multiblock Structure Hologram Projector to visualize/build the structure.

The OPU uses large amounts of Ozone to purify water, and has four different recipes that consume increasing amounts of Ozone in exchange for an increasing chance of success. The first recipe consumes 128 kL of Ozone and has a 20% chance of succeeding, and each successive recipe doubles the Ozone consumed and increases the chance of success by 20%. If there is more than 1,024 kL of Ozone in the Input Hatch, the OPU will explode. Because there can only be one Input Hatch for Ozone, the tier of the Input Hatch determines which recipes are available, with the best recipe requiring a ZPM Input Hatch, and therefore a ZPM Assembling Machine, to reach the maximum success chance of 80%. This can be further improved to 95% by feeding Grade 2 water back into the OPU, which is almost always advantageous. The recipes that the OPU can run, based on the Input Hatch tier that is needed for each, are as follows:

Automating the OPU requires producing enough Ozone during its 120-second cycle to fill up either an LuV or a ZPM Input Hatch, depending on which tier of Input Hatch is available; the lower tiers are never worth using. A Hyper-Intensity Laser Engraver (HILE) is used to convert Air into Ozone, and it can be covered in Air Intake Hatches to supply the required amounts of Air. The following table lists the minimum required voltage tier, Laser Source Hatch amperage, and Air Intake Hatch quantity that the HILE needs for the two viable Input Hatch tiers, although note that in practice the HILE is often slower than this due to the fact that it repeatedly runs short recipes as soon as it has Air available, and therefore cannot take full advantage of its parallels and has to wait for the recipe switching delay. The Extreme Air Intake Hatch, available in ZPM, can be used to replace 8 standard Air Intake Hatches. In UHV the Atmospheric Intake Hatch is unlocked, which provides essentially unlimited air.
