CHOOSING THE RIGHT WASTEWATER TREATMENT SYSTEM

Investing into a wastewater treatment system is not really a very attractive option for factories and manufacturing plants. In most cases they have to have the WWTP in order to get the license to operate the manufacturing facility. In other cases they are forced into getting a WWTP due to legislative action and non compliance of environmental regulations

It is a fact that choosing the right WWTP is not an easy matter as it means that the factory have to invest money to buy construct operate and maintain the WWTP

One of the main criteria in deciding the right WWTP is that the WWTP must be able to treat the wastewater to reach the mandatory level of effluent treatment. There is nothing to negotiate on this point.

However most factories would like to cut costs and cut corners to reduce the amount of investment. Most regard investing in WWTP is a non profitable activity which brings no financial returns.

They will call for tenders for contractors that are able or promise to achieve the effluent standards. However, in most cases after the WWTP is completed it only works in the first few months. Then the problem starts……

In many cases these companies do not ask for independent reviews from other consultants to ensure that they are not taking chances. Even their own engineers cannot provide valuable input into the choice of the best WWTP because most times these engineers they employ work on the production floor but not the WWTP

The key aspect they are looking for are:
1 Cheap cost of the WWTP
2 Low utilization of energy

Cheap does not mean it is always good. It just give the contractor a lower profit margin and that their tender have a stronger chance of being accepted


Choosing WWTP that will not use much energy. The factories do not like to pay for high utility bills. This is understandable. However they will end up very disappointed when in the end the WWTP does not live up to their requirements. Then who is to be blamed?

WWTP is not a simple system. It is in fact a very complex bioreactor or fermentor. Anything can go wrong! It is far easier to operate a normal fermentor than a WWTP!
