Question: 1 / 400

What is the minimum contact tank capacity for chlorine tanks?

15 gallons

30 gallons

The minimum contact tank capacity for chlorine tanks is established to ensure that there is sufficient time for chlorine to effectively disinfect the water before it is released into the septic system or back into the environment. A capacity of 30 gallons is typically considered the minimum necessary to facilitate adequate contact time with the chlorine, allowing it to act on pathogens and ensure that the water is safe for dispersal or reuse. This is based on industry standards that take into account flow rates, chlorine dosage, and the importance of maintaining effective disinfection processes in wastewater management. Larger capacities may be beneficial in certain scenarios, but the minimum standard is set at 30 gallons to achieve effective treatment.
