Environment and Wastewater

Low investment budget, decrease in water resources, renewable energy requirement, environmental pollution, global warming... If we have to express in the simplest way, in today’s world, we do not have any room left for waste.

Unless all humane, commercial and industrial activities are subject to purification, waste materials that are harmful to our environment are caused to emerge. Therefore, new methods are looked for in order to reduce pollution, provide clean water, use less energy and recycle a product/energy already used on a permanent basis. Despite of the increase in the population and life standards, the need for recycling water is gaining importance each day because of water scarcity in various regions.

As the results of the researches conducted on increase in environmental awareness, upgrading standards on dismissal of waste and the damages caused by purification sludges, it has been revealed that the decrease in the waste amount and dewatering are of vital importance for final dismissal of the sludge.

As Polat Makina, we offer decanter centrifuge and centrifugal separators for industrial applications, water and wastewater applications. Besides, we offer turnkey dewatering process solutions including decanter.

The aim of dewatering and purification is to enable valuable raw material within the wastewater or production waters caused in municipalities and industrial application areas to be recycled and to enable waste sludges to be disposed in an economical way without causing any harm to the environment.

Return of centrate which has gone out from the decanter operating unproductively bears the need for high ventilation. And it increases the energy cost of the facility. Obtaining much drier sludge cake decreases sludge disposal costs at a considerable level. It has a significant impact on shipment, wastewater disposal, storage, and drying costs.

Therefore, the most important aim in dewatering is to decrease the volume of purification sludge as much as possible. Because a slight increase in solid material percentage bears a serious profit in solid material disposal. Apart from such profits, realizing an effective dewatering is of vital importance for sustainable growth.

Intensification Decanter
The decanter is used for the intensification process of sludge in this application. Sludge volume for the following operation is reduced by 90% and tanks of the facility is ensured to be used effectively. Centrifuge intensificators are used for both intensify and dewater the sludge.

Dewatering Decanter
Solid materials separated are transferred to the solid output through the barrel and conical part with a spiral carrier. Solid materials are stressed in the conical part and the dewatering rate is increased.

Installation and labor costs of the decanters are low. They are advantageous in terms of hygiene and odor since they are closed systems. They have a very low infection risk.

Primary usage areas of separators in the environment and wastewater industry:

• Urban wastewater treatment facilities,
• Potable water treatment facilities,
• Industrial treatment facilities; intensification and dewatering processes.
