The Cheapest wastewater treatment technologies

It’s natural to try to cut costs in your facility and look for the cheapest wastewater treatment technologies. While the treatment itself is vital, you also have a budget to consider, so you need to think about how to reduce the cost of your operations.

The Cheapest Wastewater Treatment Technologies Options

Let’s take a look at some of the low-cost treatment options you can use within your wastewater setup. Keep in mind that these treatment methods may not be suitable for all types of wastewater or for all industries. Make sure you’re familiar with the nature and chemistry of your wastewater so you know which methods you can deploy.

Absorption

Absorption is the process of transferring atoms or molecules from a liquid to a solid surface. The value of this transfer in wastewater treatment is clear – it can remove traces of heavy metals and other harmful substances at the molecular level.

Deploying absorption within a wastewater treatment facility doesn’t have to be expensive. You can use materials such as sawdust inside a filter device, to complete the absorption process. It’s important to understand the specific types of molecules and atoms you want to remove, and choose the absorbent material accordingly.

Sand Filtration

Filtering wastewater through a relatively inexpensive material such as sand can be a viable treatment method. Sand is useful for removing pathogens from the water as it passes through, but – as with the absorption method mentioned above – you may need to research the pathogens it is working on and use the appropriate filter media to remove them.

It may be necessary to use other methods in addition to sand filtration. For example, chlorination can be used to remove pathogens from treated water without significantly increasing the cost.

Limestone Treatment

Although limestone treatment is not a stand-alone method of water purification, it does have its uses. When wastewater comes into contact with limestone, its acidity increases, which ultimately reduces the acidity of the effluent.

If you are experiencing acidity problems in your wastewater, running the water through limestone slabs may be beneficial. However, you may need to use other methods in addition to slabs before the effluent is of a quality that can be released.

Five Ways to Control Wastewater Treatment Plant Costs

Whether it’s electricity bills, sludge management, or the number of employees required, operating a wastewater treatment plant can be a financial challenge. Even neglecting maintenance can lead to significant cost increases over time. To help you overcome these challenges, we’ve identified five key areas to focus on when you’re trying to control your wastewater treatment plant costs.

Reduce Electricity Use

Energy costs are likely to be one of the biggest drains on your finances. However, there are many areas of your wastewater treatment plant where you can make significant reductions in consumption. By investing in the right technologies, you can save a significant amount of money.

Ventilation systems are probably responsible for the majority of your energy use. Experience shows significant savings simply by maintaining the system and even greater cost reductions with improved ventilation systems. This is because aeration elements wear out over time, clogging can occur, and in some cases, membranes can break. These problems significantly reduce the efficiency of the aeration process, resulting in increased energy consumption. In addition, increased pressure drop places greater loads on the blowers, accelerating their wear. Higher system pressures can lead to higher outlet air temperatures and decreased oxygen transfer efficiency, which poses a challenge to the efficient and economical operation of the treatment plant.

Maintaining proper water management

We can be more environmentally friendly and save money at the same time by recycling water in our wastewater treatment processes. Instead of using “new” tap water for activities such as flushing, cleaning equipment, or watering lawns, we can use water that has already passed through the treatment plant. This water is suitable for the purposes mentioned above and is a great way to reduce new water consumption.

There are several ways to increase the amount of water that can be reused. One of these methods is dewatering, where the filtered water is returned to the treatment process, increasing the volume of water that can be reused. However, it is important to note that the clumped material from the filtered water used during the dewatering process must be broken down. This is a crucial step to ensure that the recycled water is suitable for reuse.

Reducing the Amount of Waste Removed

The efficiency of the dewatering process is closely related to the amount of dried sludge (DS or dry matter) that must be removed on a regular basis from the treatment plant. The more comprehensive the dewatering process, the less waste that has to be transported, and thus the cost of waste removal and treatment is significantly reduced.

In practice, this means that the target for dewatering the sludge should be as high a percentage of dry matter as possible. However, it is of utmost importance to choose the right dewatering equipment for the plant treating wastewater and preparing the water drying process properly.

Disposing of sludge

Although dried sludge is considered a waste, it can also be an essential raw material.

It is naturally used in agriculture. Sludge is rich in nutrients such as nitrogen, phosphorus and potassium. It helps improve soil fertility and promotes crop growth. On the other hand, it can also contain hazardous materials, so ensuring that the sludge meets all regulatory requirements and standards for application on agricultural land is important.

Dried sludge is also used to produce biogas, which is one of the common ways to dispose of this brown gold.

It has also been found to be useful in the construction industry. Research shows that sewage sludge is a useful component in the production of some building and insulation materials. It increases their insulating capacity and reduces the cost of production.

However, in most cases, the dry material goes to composting plants. Where the sludge is homogenized (heated to reduce pathogenic microbes) and processed back into the building.

Saving manpower

With unemployment rates relatively low, labor costs are steadily increasing. In wastewater treatment plants, the optimal process design and focus on automation are essential. Automated systems can reduce the demands on operators. At the same time, automated systems are becoming more suitable for operators of large wastewater treatment plants. As they can be used to their full potential. When choosing technologies, you can turn to a screw press for dewatering or an automated polymerization plant, for example, which often do not require manpower.
