Wastewater treatment

Thanks to wastewater treatment, a process that includes different types of procedures (physical, chemical, physico-chemical or biological) whose aim is to eliminate and/or reduce pollution or undesirable water properties, access to clean water and the prevention of pollution of rivers and seas is ensured.

The goal of this process is to obtain water with the appropriate characteristics for use. The process of water treatment therefore depends on both the initial properties of the water and its intended use.

The treatment of wastewater from urban centres or industries is carried out in a Wastewater Treatment Plant (WWTP).

In the sewage treatment plant, the purification processes (which occur naturally along the path of a river) are concentrated and automated.


Pumps have contributed to the technical development of the industrial sector to such an extent that they could easily be considered one of the essential resources within the production fabric.

Since the chemical industry requires high-performance pumps that must operate without interruption and in compliance with safety and environmental regulations, choosing the right pump is crucial, especially for chemical applications. Kronoa’s team of experts meets the challenges of chemical processes by following industry best practices and always considering environmental and health and safety regulations.

Biogas and Waste

Pumps play a very important role in managing different types of waste, so it is important to choose the best pumps for pumping food waste and animal byproducts. For food waste, you need a pump that can reliably pump resistant solids and is not prone to clogging, which can only lead to downtime and lost production.

The use of different types of waste to produce biogas as a method of generating renewable energy is becoming increasingly important, especially in European Union countries whose regulations are becoming stricter in terms of proper waste management, protecting the environment, reducing CO2 emissions, and promoting green or ecological energy.

The biogas plant is the system responsible for the conversion of organic material into biogas. There are different types, especially in terms of size, but the basics of operation are the same for all of them. The interest of biogas lies in the methane, which has a calorific value of 10 KJ/m3 and can therefore be used as a renewable energy source.

In a collector, which serves as a biofilter, the decomposition of organic material is used to produce electrical energy, thermal energy, and biofuel.
