Through continuous business development, Hydrok UK Ltd has introduced new products into the portfolio of solutions available to engineers within the UK water industry. Hydrok's heritage as a key manufacturer and supplier for storm water overflow screening technology has positioned the company firmly within the management of water within the networks particularly focusing on Storm Water control and treatment.

The future challenges facing water companies include the continued control of storm water flows within the sewer networks and also the design of sustainable systems as green and brown field sites are developed. Hydrok also exclusively represent Steinhardt GmbH based in Frankfurt Germany who, with over 25 years of experience in this area, produce some of the most widely installed systems in Europe for flow control, flood alleviation, tank cleansing and sewer screening.

Eliquo Hydrok, with its established ethos of providing innovative water engineering solutions, offer highly efficient, significantly reduced energy solutions for the Wastewater Treatment Process using fine bubble aeration systems and fixed bed media. These systems deliver extremely cost effective, life time saving solutions whether utilised for retrofit, refurbishment/expansion or new build.

The Eliquo Hydrok experience in sludge treatment is comprehensive. Sludge thickening, digestion, dewatering and drying are all part of our portfolio. With our proprietary, innovative design concepts, we provide advanced sludge treatment solutions. Our LysoTherm® system improves the gas yield and reduces the amount of residue for disposal.

The best-possible sludge digestion enables sewage treatment plants to operate with energy self-sufficiency and in some cases with an energy surplus. This is achievable in combination with co-substrate utilisation, with energy-related improvements in the mechanical and aerobic biological wastewater treatment or with the additional use of renewable energies, such as wind power and photovoltaics. We would be happy to work with you on a tailor-made system design.


Sustainable Urban Drainage Systems (SUDS) offers an alternative approach to traditional drainage. The use of SUDS to reduce levels of diffuse pollution and flooding is rapidly becoming more widespread in the UK and the Eliquo Hydrok SUDS portfolio offers products for control of water flow, quality and flood management within the urban water networks. An integrated approach considering quality, quantity & amenity.
