News from industrial water technology

ALMAWATECH has commissioned a high-performance seawater treatment plant for the renowned GEOMAR Helmholtz Center in Kiel. The aim was to filter and treat raw water from the Kiel harbor basin in such a way that it meets the high requirements of marine biological and chemical research projects. The plant was planned and implemented with a particular focus on operational safety, corrosion protection and ease of maintenance. In this article, we show the technical highlights of the plant and take a look behind the scenes of the project.

An ALMA CHEM MCW CP batch plant was successfully commissioned in Leipzig. It treats around 20 m³ of specialty chemicals wastewater per week and reliably removes heavy metals, AOX, hydrocarbons and chromium(VI). Precipitation, flocculation, neutralization, chamber filter press, gravel filter and ion exchanger ensure compliance with the limit values in Annex 40.

A modern ALMA BHU EGSB reactor in stainless steel construction was successfully commissioned at a leading bioethanol producer. The two-stage reactor (680 m³, 24 m high, 6 m diameter) is designed for a load of 10,000 kg COD/day and mainly treats vapor condensates and mixed wastewater from production. Thanks to the innovative 3-phase separator with round gas collection system, the plant operates stably, without clogging and without foaming - and at the same time produces valuable biogas for the energy supply.

Neutralization systems are indispensable components in industrial wastewater treatment. They ensure that acidic or alkaline wastewater is reliably adjusted to a permissible pH range, thus guaranteeing both legal limits and the protection of downstream processes. In addition to traditional neutralization with acids and alkalis, CO₂ neutralization is becoming increasingly important, as it is characterized by higher operational safety, better environmental compatibility and sustainable economic efficiency.
