Water intake

To secure fresh water intake to your process, different types of treatment can be needed. Some of these also generate a waste stream. Alfa Laval offers a number of solutions to help you deal with this in an efficient and sustainable way. Examples include water for cooling towers, process water preparation and treatment of waste from reverse osmosis.

Industrial wastewater treatment

Industrial wastewater varies considerably in specification, depending on type of industry and local habits. In many cases it is not accepted by the municipal wastewater treatment plant, so pre-treatment or complete on-site treatment is needed. Alfa Laval offers several compact, easy-to-operate wastewater treatment technologies that produce clean effluent either for discharge or further treatment for water reuse.

Product recovery

Valuable products are normally lost in waste streams from industrial processes, and are costly to treat or dispose of. But many waste products can be effectively recovered. Alfa Laval can help you convert cost to profit. We offer a variety of general or industry specific solutions that help you recover products of value that you can either reuse or sell.

Sludge treatment

The liquid content of sludge from municipal and industrial wastewater treatment and waste from other operations has a high impact on disposal costs. Alfa Laval supplies equipment that cover the entire sludge treatment process, including thickening, dewatering, heating, cooling, heat recovery, digestion and pasteurization, as well as advanced control systems for optimizing plant operation and reducing manpower requirements.

Tertiary treatment

Most often some form of tertiary treatment is necessary after industrial and municipal wastewater treatment to achieve an effluent quality good enough for discharge to a nearby recipient (sea, lake, etc.). And it is a must if treated wastewater is to be reused. Alfa Laval offers two types of tertiary treatment that produce effluent clean enough to meet strict discharge criteria or for water reuse.
