Industrial water treatment using a modular system

Plants for industrial water processing and wastewater treatment designed using a modular approach have an advantage in a global implementation strategy.

The German company, EnviroChemie, head quartered in Rossdorf has been developing, manufacturing and installing systems lo clean industrial wastewater, circulate water and condition process water for over 35 years. Its engineers and technicians have always applied a decentralised solution and developed custom designs for customers and for sectors. As well as fully individually manufactured system solutions, from the early days compact standard ready-Tiade systems were also implemented. Depending on customer requirements the water and wastewater processing challenges are resolved using one of the company's proprietary biological, chemical-physical or membrane technology solutions.

In 2008 the company started developing the EnviModul system. The construction of the existing processes on offer was modified so that they fit into the pre-fabricated, high-quality space modules and can be combined in many different ways. An EnviModul component replaces operational buildings constructed from steel and concrete, is semi-mobile, adaptable to different climatic conditions, durable and visually attractive.

Construct and reconfigure rapidly
Compared with conventional plant construction, modularised solutions can be implemented significantly faster and at a lower cost. They can be adapted more easily to variable operating conditions at customer sites. And where required, they can be relocated to other operating facilities.

Decentralised solutions for treatment of wastewater and process water or for water recycling are customised to meet operating requirements and configured individually. Detailed, basic empirical information about the flows of materials, such as where they arise, what they contain and their concentrations, are just as important as the exact determination of the quality of water or substances to be produced. Official requirements for the issue of permits must be taken into account. Depending on these requirements, the EnviroChemie experts select the most suitable processes and steps within processes, combine them and size them. The process stages are then configured and designed using the necessary number and sizes of modular cells. Depending on the plant single modules between Ihree and twelve technology required and the size of the plant, the EnviModul system components can be metres in length, which can be transported in their finished state by lorry, double components which are transported in sections, or complete buildings, which may consist of up to 20 modules.

Components with solid individual elements
The construction of the module cells is based on corrosion-resistant steel frames with several coats of paint and ISO corners for easy transport. The modules are insulated on all sides and feature plastic-coated inner lining. For the floors, various design options in steel, plastic or gratings are available. Modules housing media have a 100 mm high watertight floor tray. Windows with insulated glass or light domes can also be fitted where required. Heating and climate control is available to suit regional requirements. The roofs of the modules can simply be opened or moved back to enable the easy maintenance and care of dip moulding membranes in membrane filter systems or membrane biologies. In a frosl-free environment, the housing modules are open at the sides and are erected without any wall coverings. This solution saves costs and facilitates operation and maintenance. As a general rule, the plants are loaded using a truck-mounted crane and - just like prefabricated garages - set on deep foundations, strip foundations or concrete slabs.
