The wastewater treatment is performed in three subsequent treatment stages. The effluent from domestic, agricultural or industrial sources passes a preliminary treatment step where solids are separated out and chemical treatment is applied where necessary. The secondary treatment consists of Biological Disks and Lamella Separators that are used for the final clarification step. Optional advanced treatment can then be applied thereafter.
PP-RCT technology PP-RCT fibre composite pipes, made of the proven material PP-RCT, consist of a PP-RCT outer and inner pipe and a middle layer of a PP-RCT/PP glass fibre mixture and are an alternative solution to conventional pipe systems suitable for e.g. cooling and air conditioning systems, rainwater utilisation systems, drinking water and sanitary installations and industrial pipeline construction.
The complete range of PP-R pipes and fittings for the environmental supply of water.
Plastic pipes made from Polypropylene Random Copolymer (PP-R) were introduced more than 30 years ago. Since then, they have been used mainly for hot and cold water pipe systems and have significantly contributed to the growth and acceptance of plastic pipes for plumbing and heating systems. While system components have been gradually improved over time, no resin improvement of particular significance has happened in the last 20 years.
