Wastewater Treatment System Renovation and Upgrade
After long years of operation, wastewater treatment plants are prone to deterioration, overloading and poor performance. This not only raises operating costs but also makes it difficult for the effluent to meet environmental standards. So what are the signs that a business needs to renovate and upgrade its wastewater treatment system, and what is the most effective remedy?

1. When does a wastewater treatment system need renovation and upgrading?
For wastewater treatment systems that have been in operation for many years, or that have deteriorated or suffered serious damage so that the effluent no longer meets environmental standards, businesses need a renovation and upgrade plan to avoid the risk of penalties and operational disruption. Compared with investing in an entirely new system, renovation can save businesses money because existing treatment tanks, equipment and machinery that still work well can be reused.

In the past, when environmental protection was not strictly enforced, many businesses did not pay real attention to investing seriously in wastewater treatment systems. As a result, many systems were designed merely as a token measure to get past inspections by the authorities.
Others built systems and centralized wastewater treatment facilities while cutting operating costs, resulting in treatment systems that perform poorly and do not match their design capacity. In addition, many businesses still have flawed original designs or wrongly applied, unsuitable or unverified machinery and equipment, making system operation and maintenance difficult. Another cause is that the people supervising and operating the system lack the expertise to detect incidents, faults or abnormal changes in the treatment process.
In short, if any of the following signs appear, the business needs to renovate and upgrade its wastewater treatment system:
- The system is old and can no longer handle the required treatment capacity as production volume increases;
- Increased wastewater flow, additional production lines, changes to the treatment process, etc.
- The effluent does not meet permitted standards and does not comply with regulations;
- Machinery and equipment break down during operation or are damaged, compromising the quality of the treated water;
- The machinery line needs upgrading to meet production standards.
2. Common problems when renovating and upgrading a wastewater treatment system
System renovation must be carried out by an experienced technical team and specialists, because countless unexpected problems can arise during renovation that a young, inexperienced contractor would struggle to handle. Common problems include:
- Abnormal microbial die-off caused by an abnormal increase in wastewater load;
- Low microbial density due to nutrient deficiency;
- Sludge turns black and settles very poorly;
- Slow nitrification due to anoxic conditions;
- High suspended solids in the effluent of the biological settling tank because small sludge flocs settle poorly;
- Neglected periodic maintenance and servicing of equipment and machinery, causing some equipment to rust and perform poorly.
