What is the primary function of membrane lined tanks?

The primary function of membrane lined tanks is to contain liquid spills and leaks. These tanks are designed with a flexible membrane that acts as a barrier, effectively preventing any leakage of the contents stored inside. This feature is particularly important in environments where safety and environmental protection are paramount, such as in the storage of hazardous materials or substances that could contaminate the surrounding area.

Having a membrane lining helps to ensure compliance with environmental regulations by mitigating the risk of spills, which can lead to soil and water contamination. By containing potential leaks, membrane lined tanks provide an additional layer of safety and security for both the facility and the surrounding community.

The options related to storing liquids in semi-solid form, facilitating easy cleaning, and increasing pressure resistance do not accurately reflect the main purpose of these tanks. While these factors may be relevant in some contexts, they do not capture the critical role that membrane lined tanks play in leak containment and environmental protection.
