Future trends to watch for include:

Implementation of stricter environmental regulations which may drive the need for more advanced wastewater treatment technologies.
Increased adoption of sustainable manufacturing practices aimed at reducing overall wastewater generation.
Technological innovations in water recycling within industrial processes that can significantly impact future wastewater volumes.
