Effluent Treatment Plants

The design, manufacturing, supply and installation of Waste Water Treatment Plants for surface treatment rinse waters

Galvatek’s experience in industrial water and wastewater treatment plants (WWTP) dates back to the very beginning of the company. Our water treatment plants typically serve surface treatment plants, completing the overall plant project by producing clean water to the plant and/or treating the surface treatment wastewater utilising the latest technological and environmentally friendly solutions.

Energy efficiency and environmental friendliness

The two main types of industrial wastewater treatment plants are physical-chemical neutralisation systems and evaporation systems. Galvatek supplies effluent treatment plant (ETP) applications for the aviation, aluminium, energy and various metal finishing industries. Our wastewater treatment plants often include special applications, such as chemical recovery and/or demineralised water production.

Wastewater neutralisation plants

Wastewater neutralisation plants are the most typical type of wastewater treatment plant in Galvatek’s process plant project deliveries.

Galvatek offers tailor-made water and wastewater treatment plant solutions for the aviation, aluminium and other surface treatment sectors. In these cases the effluent is rinse water from a surface treatment plant containing impurities such as dissolved metals and suspended solids, which must be removed from the water before sewage according to environmental regulations and norms.

Physical-chemical treatment process of wastewater

Typically, our wastewater treatment plants utilise traditional physical-chemical treatment steps, such as neutralisation, flocculation, clarification and filtration. We refer to these types of wastewater treatment plants simply as neutralisation plants. The pH of wastewater is adjusted, and the required coagulation/flocculation chemicals are added to the water to convert the dissolved components into solid form. The clarification step typically involves a lamella clarifier in which flocculated solids are separated. Solid sludge is further dewatered using a chamber filter press.

Sizing according to wastewater usage

Wastewater neutralisation plants are always scaled and designed according to the needs of the customer and the quantity of the wastewater to be treated. Typically our neutralisation plants can process up to 10 m3/h, but Galvatek can also deliver larger plants as required.
