Common Mistakes To Avoid When Choosing Wastewater Treatment Equipment

If you are on the market for wastewater equipment supplies or you want to upgrade your current equipment, there are a few common mistakes you should avoid.


Improperly characterising the water makeup to the equipment


It is very important to properly characterise the incoming supply of water before you prepare for equipment specifications. You should therefore take multiple samples at different types and under various operation conditions. Always remember to measure the temperature of the water and the SDI on each sample.


Assuming that the supplier knows best


When buying your treatment equipment, it is important to understand that every supplier wants to sell and they can do everything to convince you to buy their equipment even when they do not have the right equipment for your needs. Unless you choose the right supplier like Xylem, you should know that the supplier of your wastewater equipment supplies in NZ can be wrong.


It is therefore important to involve plant personnel such as maintenance staff, operations staff and engineers throughout the design to installation stages.


Under sizing your reverse osmosis pre-treatment systems


A cold snap or high turbidity can cripple the treatment equipment ahead of the reverse osmosis or ion exchange. It is therefore important to put an extra capacity to handle water that feeds the ion exchange and RO systems so that this is never the production bottleneck.


Improperly sizing your pumps


The reverse osmosis feed pumps are a critical part of the RO system. They are also expensive. It is therefore important to have a sufficient pump for your required feed flow.


Poorly integrating new and existing equipment


When you buy new wastewater equipment supplies, it is important to remember that you need to integrate your new equipment with your old ones. If you do not do proper integration, you will end up overworking your new equipment and this can cause a system failure.
