When using two-piece dosing tanks, how should the sections be joined?

In the context of joining two-piece dosing tanks, the correct approach involves utilizing mastic, butyl rubber, or other approved sealants. These materials are specifically designed to create a watertight seal that can accommodate the necessary flexibility and durability required in wastewater applications.

Using sealants ensures that the joints remain intact and can withstand potential movement or shifting of the tank sections due to soil settling or other environmental factors. These materials also prevent leaks, which could lead to contamination of the surrounding soil and groundwater, posing environmental hazards.

While welding, bolting, and clamping could be methods for other applications, they may not provide the same level of flexibility or water-tightness required for dosing tanks. Welding might not be suitable for plastic tanks, bolting could create points of failure that sealants do not, and clamping may not secure a robust enough seal to prevent leaks or allow for any thermal expansion that may occur. Therefore, using approved sealants is the most effective and recommended method for ensuring the integrity and functionality of two-piece dosing tanks.
