The fight against micro-pollution
In the Netherlands, we collect domestic wastewater for treatment and purification purposes. This has resulted in a clear improvement of our surface waters. A new challenge on the horizon is tackling micro-pollutants by applying additional or new combinations of purification systems. After passing the sewer, our domestic wastewater enters a sewage treatment plant together with organic matter, phosphorus and nitrogen. Here, the water is treated. In this process, the organic matter is broken down into water and carbon dioxide. This process requires a lot of oxygen (oxidation ditch), resulting in the formation of sludge.
After the (biological) cleaning process, the water ends up in the post- sedimentation tank. This is a rotating tank where the purified water is separated from activated sludge. The circling tracks of the tank have to endure a lot due to pressure loads and weather influences. These circling tracks will therefore slowly crumble, causing the wheels of the tank to jam. This in turn means the sludge is not (or no longer) sufficiently discharged and the quality of the purification process/water decreases.
To prevent or remedy such situations, Prokol offers various solutions for protecting concrete and/or metal for both walls and floors and for making platforms anti-slip.
Drinking water is one of our basic needs
Drinking water must be clean and safe to drink. The government is taking measures to protect the quality of drinking water in the Netherlands. Drinking water companies purify groundwater and surface water to provide clean and safe drinking water. Strict legal rules and regulations apply to the extraction, purification and supply of tap water.
In addition, it has been determined how many substances and organisms are allowed to occur in drinking water.
These legal quality requirements for drinking water are contained in the Drinking Water Decree. For example, drinking water may only contain very limited amounts of lead and mercury (10 micrograms of lead and 1 microgram of mercury per litre of water). These requirements are based on the European Drinking Water Directive.
Clean drinking water is therefore of vital importance. Our water is subject to continuous monitoring to ensure the quality is guaranteed. The safe production, storage and transport of drinking water to the end user are essential in this process.
Prokol seamless liners meet the requirements
To realise safe drinking water, drinking water systems must be set up properly. Prokol offers a number of liners that can meet this requirement. These liners are applied seamlessly and quickly and meet both the English and German drinking water standards, which are laid down in a certification for these applications.
Some of the advantages:
- Permanently elastic and crack-bridging
- Resistant to organic and inorganic compounds
- Resistant to high and low temperatures
- Heavy-duty ready
