Products & Services

Eliquo Hydrok provides engineered solutions that support the effective treatment and management of liquid and solid waste streams. Building on proven delivery for municipal customers, we are now expanding into the non-municipal bioresources and anaerobic digestion (AD) markets.

Our approach is grounded in practical delivery. We design, fabricate, manufacture and integrate equipment that is built to operate reliably in real-world conditions, where consistency, uptime and ease of operation are critical. With UK manufacturing centres of excellence, we can support repeatable delivery of DfMA, plug-and-play products and long-term aftercare, helping you standardise where it makes sense and reduce project risk.

Within the AD sector, digestate management is an area of increasing importance. Rising transport costs, regulatory pressures, and the need to maximise value from outputs are driving demand for more efficient and controllable solutions. At the same time, AD and biogas have a critical role to play in decarbonising heat and power, so reducing losses across the process matters. That includes helping operators capture aberrant emissions from digestate and handling steps, turning avoidable methane release into measurable performance improvement. This is where our technologies can add value.

ELODRY® is a low-temperature belt drying system designed to reduce the volume and mass of dewatered digestate and sludge, producing a stable, easier-to-handle end product while significantly lowering transport and disposal requirements. By removing moisture from the cake, overall mass can typically be reduced by around 70–80%, helping operators cut haulage movements, associated costs and carbon emissions. For many non-municipal sites, this also translates into a very practical benefit: more controllable storage and improved resilience when digestate must be held ahead of landspreading windows.

ELODRY® is engineered for high energy efficiency, using integrated heat recovery to pre-heat incoming air from the dryer exhaust stream and minimise thermal demand. This delivers low specific energy consumption while maintaining reliable drying performance, making it well suited to AD sites focused on operational efficiency and net zero objectives. In addition, drying can reduce on-site storage requirements and improve planning certainty—particularly if the application of wet digestate becomes more restricted over time. ELODRY® also supports a practical DfMA approach through a compact, modular layout, with enhanced operational safety features including temperature monitoring, particle detection and fire protection systems.

ELODRY® can also play an important upstream role in pyrolysis and other advanced thermal conversion processes by drying digestate or sludge to consistent dry solids levels. This creates a more suitable feedstock for conversion pathways such as biochar production, supporting energy recovery, potential carbon capture opportunities and the development of higher-value end products.

ELOVAC® complements this by recovering dissolved methane and carbon dioxide via vacuum degassing. It provides a controlled approach to biogas recovery and collection, helping you reduce aberrant emissions from digestate handling, strengthen site safety and improve process stability. For non-municipal operators who are focused on cost and controllable outcomes, ELOVAC® can also help tackle two common pain points: struvite formation (which can drive blockages, downtime and unplanned maintenance) and improved dewaterability. Better dewaterability can reduce polymer demand and improve cake capture, while supporting practical digestate management when material needs to be retained on site ahead of seasonal landspreading windows.

Both systems are proven within wider bioresources and waste processing applications and offer strong potential for non-municipal AD operations, including food waste, agricultural and industrial feedstocks, where digestate handling, emissions performance and process uptime are key commercial drivers.

Smart operations and maintenance

We also recognise that availability is driven as much by day-to-day operability as it is by core process performance. Where appropriate, we can offer ELOVAC® and ELODRY® with our inCTRL OpsControl “smart” capabilities, helping you simplify maintenance, standardise operational routines and respond faster to developing issues. This can include clearer asset visibility, alarm management and performance monitoring—supporting reduced unplanned downtime and a more predictable cost base.

Beyond individual technologies, Eliquo Hydrok delivers a full-service approach. From early-stage design support through to manufacture, installation and commissioning, we work alongside you to ensure systems are appropriately specified and effectively integrated. Our aim is to be your long-term partner of choice for DfMA, plug-and-play solutions that can be deployed repeatedly across portfolios and upgraded over time.

Our focus is always on delivering solutions that balance performance with practicality: systems that meet technical requirements and support day-to-day operations. Through the wider ELIQUO Water Group and the SKion Water family, we can also bring forward proven, high-value technologies and specialist expertise when they are the right fit for your site.

For AD operators, designers, constructors and investors, this means access to proven engineering, backed by UK fabrication capability and a team that understands the importance of reliability, efficiency and long-term value. ELOVAC® and ELODRY® are our first wave into the non-municipal AD/biogas market, with further high-value products planned for successive phases as we broaden our offering.

About the business

Eliquo Hydrok is a UK-based engineering business with over 30 years of experience in water, wastewater and biosolids processing. Over that time, we have built a strong reputation for delivering robust, reliable solutions across the UK and Ireland. Backed by the ELIQUO Water Group and the wider SKion Water family, we combine international R&D with UK delivery, engineering and fabrication capability. Recent investment in advanced robotics strengthens our manufacturing centres of excellence, creates skilled employment and helps ensure resilient UK supply.

We are now applying that same delivery focus to the non-municipal AD and biogas sector, starting with ELOVAC® and ELODRY® as our first phase of entry. Our core strength lies in our ability to design, manufacture and integrate systems that perform in practice. We understand that success is not defined by specification alone, but by how equipment operates over time.

Our mission is to be the partner of choice for our customers across water, wastewater and bioresources operations. This is underpinned by a commitment to quality, accountability, and long-term relationships with the organisations we work with.

Our vision is to deliver world-class solutions that enable cleaner water and reduce pollution to land and air. This drives our focus on sustainable engineering and continuous improvement across everything we do.

As part of the ELIQUO Water Group and the wider SKion Water family, we can draw on additional capability in bioresources, with experience developed across European markets over the past decade. This strengthens our ability to support evolving sectors such as anaerobic digestion and enables us to bring the best-fit technologies from across the group to the UK market in successive waves.

While our background is rooted in municipal applications, we recognise that the AD sector operates with different drivers, commercially and technically. Our approach reflects this. We are investing time with the industry to understand specific needs, investment models and priorities, and to support the sector’s role in decarbonising heat and power through robust, high-uptime plants.

Through collaboration with operators, designers, constructors and investors we aim to ensure that our solutions are aligned with real world AD requirements.

For ADBA members, Eliquo Hydrok offers a combination of proven engineering, UK fabrication and delivery capability, and a commitment to building long-term partnerships. Whether you are standardising assets, delivering new-build facilities or upgrading existing sites, we aim to be a practical partner for DfMA and plug-and-play solutions that are easy to integrate, operate and maintain.
