The Water Resources Act (WHG) and the AwSV regulate the safe handling of substances hazardous to water. What companies must observe when storing, filling or using - explained in compact form.
What does the path to a new wastewater treatment plant look like - step by step from the perspective of an engineer at an industrial company?
This is exactly what this interview with Tobias Höfer, Project Manager at MÖLLER Medical GmbH in Fulda, Germany, is about. The company, which has stood for precision in medical technology for over 70 years, planned and implemented a new chemical-physical wastewater treatment plant together with ALMAWATECH in 2023. In this interview, Mr. Höfer explains how he got to grips with the complex topic as a career changer, what challenges had to be overcome during the project planning and integration of the plant - and what really matters when choosing a plant manufacturer.
Wastewater treatment in the metal industry requires efficient and reliable solutions in order to comply with the legal requirements of Annex 40 of the Wastewater Ordinance and at the same time ensure economical and stable operation. Chemical-physical (CP) plants (also known as precipitation and flocculation plants) play a central role here, as they represent an efficient and adaptable method for treating industrial wastewater with different levels of contamination.
A high TOC value is a major problem for industrial reverse osmosis and water recycling plants, as organic contamination impairs efficiency and increases operating costs. In this article, we show how our ALMA BioFil Compact biofiltration system effectively solves this challenge.
Treatment of 12 m3 of acidic and metal-containing wastewater from electroplating, mass finishing and electropolishing, installed in a two-storey ALMA module for the medical technology manufacturer Möller Medical GmbH.
Silicon compounds such as silicon dioxide and silicic acid are among the most problematic substances in water treatment with reverse osmosis systems. They can cause deposits and significantly impair the performance of the membranes. In this article, you will learn why silicon compounds pose a challenge and what effective measures are available to protect your system from damage.
From softening and decarbonization to demineralization, special ion exchangers ensure that water is optimally treated to meet the respective requirements. In this article, we explain how these processes work and shed light on how mixed-bed filters further optimize water quality through precise fine purification.
Reverse osmosis systems are powerful, but sensitive to free chlorine, which can permanently damage the membranes. This article explains why this is the case, which chemical processes take place and how you can protect your reverse osmosis systems.
Ion exchangers are indispensable components in water treatment. They specifically remove dissolved ions from the water and adapt its quality to a wide range of requirements - whether for industrial processes, the production of demineralized water or the recycling of process water. In this article, we explain how cation and anion exchangers work, which ions can be removed by the different types of resin and when it makes sense to use a CO₂ trickle filter.
Biofiltration offers an effective way of pretreating organically contaminated wastewater so that it is optimally prepared for further treatment in reverse osmosis systems. Organic compounds and nitrogen are specifically broken down with the help of sessile microorganisms.
