Our approach
Based upon our years of experience in treatment of polluted ground- and process waters we are able to find quickly the right solution for your treatment challenge. Every case and client asks for tailormade solutions. We do not focus on a single technology but always choose for an approach or technology that is most suited. We also check if source solutions can lead to less water that needs treatment.

Our approach is practical and solution-oriented in all our services. Together with our clients we will find the right treatment solution. Not only we design, install and deliver water treatment systems, if necessary we also carry out bench or pilot scale tests to precheck a solution. In the end we can organize the detailed design, instalment and – if wished – the operation & maintenance of your water treatment system. 

We deliver a service. Each project is a puzzle whereby the pieces have to be put into the right place,” says Jack van Rossum, water treatment specialist at HMVT.

A composite installation with multiple purification phases is often the best solution for a water treatment challenge. We have broad experience in the following treatment processes:

  • Physical separation techniques: separators, filtration, iron removal, and aeration
  • Biological treatment: biorotors and bioreactors.
  • Chemical treatment: acid and caustic dosages, ozone, UV and hydrogen peroxide treatments.

Our plants are used for a variety of applications – for the treatment of groundwater or industrial process water within petrochemical and pharmaceutical industries. All our solutions meet stringent safety requirements, including the ATEX guidelines. Prior to the handover, we perform a Risk Inventory and Evaluation to ensure that the plant works in a safe manner and complies with all European Guidelines. 

It is also possible for us to install temporary water treatment systems, for instance to bridge a maintenance period. This avoids the operations of the customer grinding to a halt during this time. Temporary water systems are often rented incl. operation & maintenance.

Our Water Team is formed by process water engineers with a lot of experience in both physical/chemical as well as biological water treatment processes. In our workshop we pre-construct our treatment systems prior to shipment to and instalment on-site. For the (pre) construction of our treatment systems we have a dedicated and experienced team of mechanical, electrical and control engineers. 

Nature Based Water Treatment
Beside our more classical physical/chemical water treatment solutions we also have specialized ourselves in water treatment of complex chemical pollutants in helophyte ponds, also called constructed wetlands. A constructed wetland is a treatment system in which the pollutants are removed by biological processes and that is integrated into its natural environment. Whereas helophyte ponds are often used to treat domestic type of wastewater, we design our constructed wetlands to remove more complex pollutions. These pollutants can vary from oil-based products to all kind of (chlorinated) solvents or even more exotic. When a water is treatable via a constructed wetland the low energy and operating costs are an interesting advantage.

The design, instalment and operation of a constructed wetland is a very specialized business. We have successfully carried out such projects in the past and would like to assist you with similar cases.
